富士通 LifeBook U772 超级本测评
What is the first thing that comes to your mind when you think of ultrabooks? Slim case (perhaps metal), 13-inch screen, low weight and maybe an SSD drive besides a long battery life?
In addition to these basics, Fujitsu rather seemed focused on the idea of how to install as much hardware as possible into the laptop's smaller size while designing the Lifebook U772. Therefore, the 14-inch screen is installed in a case where rivaling manufacturers would at most use a 13-inch screen, among other things. The U772's price starts at about 1200 Euros (~$1513) depending on the configuration.
Naturally, it has to convince - the new Lifebook's target group is heavily fought over. Many manufacturers fight for supremacy in the premium price range of 1000 to 1300 Euros (~$1261 to $1639) with well-designed, elegant ultrabooks. The main competition is set up well here. Principally, it was Apple who invented the ultra-portable notebook category - long before the "Apple-less" rivals - via its MacBook Air and omitted a DVD drive for the first time in 2008. Now, besides the MacBook Air 13-inch, particularly Asus has become just as an important player in this sector with a few of its Zenbooks, e.g. UX31A or UX32VD. But Samsung also offers slim and mobile devices in the high-end sector with its Series 9 (see 900X3B-A01).
Many of these laptops feature very high-res screens with up to 1920x1080 pixels in a 13.3-inch screen size in addition to the typical ultrabook advantages. Is a 14-inch HD screen enough to at least draw even with the competition?
来到你的头脑，当你觉得ultrabooks的第一件事是什么？修身的情况下（可能是金属），13英寸的屏幕，重量轻，也许除了延长电池的使用寿命的固态硬盘驱动器？
除了这些基本，富士通，而似乎集中在如何尽可能多的硬件安装到笔记本电脑的尺寸更小，而设计的LifeBook U772的想法。因此，安装在14英寸的屏幕相媲美制造商的情况下，最多使用一台13英寸的屏幕，除其他事项外。 U772的价格开始于约1200欧元（〜$1513）的配置。
当然，这要说服 - 新通Lifebook的目标群体的大量战斗。许多制造商争夺霸权溢价的价格区间为1000〜1300欧元（约$1261至$1639）精心设计，优雅的ultrabooks。主要的竞争以及在这里设立。原则上，这是苹果是谁发明的超便携笔记本电脑类 - 很久以前的“苹果”对手 - 通过它的MacBook Air，并省略了DVD驱动器第一次在2008年。现在，除了13英寸的MacBook Air，特别是华硕已经成为其Zenbooks几个只是作为一个重要的球员，在这一领域，例如： UX31A或UX32VD。不过，三星还提供了超薄和移动设备在高端的行业，其系列9（900X3B-A01）。
这些笔记本电脑配备了许多非常高清晰度的屏幕，高达1920×1080像素的13.3英寸的屏幕尺寸除了典型的Ultrabook的优势。是一台14英寸的高清屏幕，足以至少画，甚至与竞争吗？
Case
The U772 looks very impressive when just unboxed. The first positive thing we notice when picking up the new Lifebook for the first time is its chassis' low weight of 1.4 kg (3.1 pounds). When placed on our table, the case's slimness impresses us. With a height of 1.56 cm (0.6 inches), Fujitsu's ultrabook is actually over a millimeter slimmer than the MacBook Air 13-inch. This is also the reason why the RJ45 LAN port is designed as a flatter connector.
Nevertheless, its rigidness is satisfying. The slim base is extremely stiff and even the display lid defies quite a bit of pressure considering its narrowness. In return, Fujitsu's laptop is not completely convincing in terms of feel. The display lid's magnesium surface rather has a plastic feel to it. The base unit makes a much higher-quality impression.
The U772 even manages well the test that has taught many lightweight notebooks the meaning of fear - the opening test. A tiny recess is on the lid's center front edge and intuitively indicates where the laptop can be best opened. The lid opens very easily - even with only one hand without lifting the base for one second - great! When the display is brought into position, it usually stays there immediately and stably without rocking for a long period. The long hinge's stability is immediately noticed when adjusting the opening angle precisely. The maximum opening angle of 155° is just as thrilling. Thus, it is possible to work pleasantly on the Lifebook when it's placed on the lap during a cramped train ride.
刚拆箱时，U772看起来非常令人印象深刻的。我们注意到，当第一次拿起新的LifeBook第一个积极的事情是它的底盘低的重量为1.4公斤（3.1磅）。我们的餐桌上，当放置的情况下的苗条让我们印象深刻。随着高度为1.56厘米（0.6英寸），富士通的Ultrabook实际上是比MacBook Air13英寸超过一毫米的轻薄。这也是原因的RJ45 LAN端口被设计成一个平坦的连接器。
然而，它的坚硬程度是令人满意的。苗条的基础是非常激烈的，甚至的显示屏盖违抗相当的压力位考虑它的狭隘性。作为回报，富士通的笔记本电脑是不是完全信服的感觉。显示屏盖的镁表面，而它有一个塑料的感觉。基座单元使一个更高品质的印象。
U772甚至管好，教了很多轻量级的笔记本电脑恐惧的含义 - 开放测试的测试。一个微小的凹陷处中心前盖的边缘，最好打开笔记本电脑就可以直观地表示。打开盖子很容易 - 即使只用一只手，没有一秒钟 - 大提升的基础！当显示被带进位置，它通常是呆在立即稳定了很长一段没有摇摆。长铰链的稳定，精确调节开启角度时，立刻就注意到了。最大开启角度为155°是一样惊心动魄。因此，它是可能的工作愉快富士通LifeBook时，它被放置在一个狭小的火车车程，上一圈。
Connectivity
It is increasingly becoming untrue that ultrabooks frequently do not harbor many ports due to their chassis' slim design. The U772 does not blunder here either.
Fujitsu installs everything of distinction among interfaces. For example, two USB 3.0 ports, an HDMI socket and the mini RJ45 port as well as an SD-XC card reader are on the case's right. The power socket, Kensington lock slot, one USB 2.0 port and headphone jack are on the left. Additionally, a SIM card for the built-in UMTS modem can be inserted at the rear below the display hinge.
Since Fujitsu has primarily designed the Lifebook U772 for business customers, a docking port is also installed on the bottom and allows adding other interfaces via a docking station. Thus it is probably ahead of many competitors in this device category because they usually omit this expansion option.
这是越来越不真实的，ultrabooks经常不怀有许多端口，由于其底盘的超薄设计。 U772并没有犯错。
富士通将所有文件安装接口之间的区别。例如，两个USB 3.0接口，一个HDMI插口和迷你RJ45端口，以及一个SD-XC卡阅读器的情况下的权利。在左边的电源插座，Kensington锁槽，1个USB 2.0端口和耳机插孔。此外，SIM卡为内置在UMTS调制解调器可以在下面的显示器铰链的后部插入。
由于富士通公司主要为企业客户设计的LifeBook U772，还安装了一个对接端口的底部，并允许添加其他接口通过对接站。因此，它可能是此设备类别中的许多竞争对手，因为他们通常省略此扩展选项。
Communication
The U772 proves to be communication-eager. Of course, you can connect to wired LAN not only via the included RJ45 dongle, but also wirelessly via WLAN (b/g/n - 2 x 2 Centrino 6205N) or UMTS (Sierra Wireless Gobi 3000). Intel's WLAN solution also supports the proprietary Wireless Display technology, which transmits screen content to monitors/projectors/flat screens that support this technology without cables. Bluetooth 4.0 is also on board and is covered by a dedicated Broadcom module (BCM207002).
Security
No half-measures are made here. In addition to the above mentioned port for a laptop lock, TPM (Trusted Platform Module) is installed as well as a fingerprint reader that is located in the wrist rest's lower right corner and thus cannot be enabled accidentally while typing. Besides these features, it is also possible to encrypt hard disk content. Security is ensured for this ultrabook.
Accessories
Apart from the user's manual, the PSU and the aforementioned mini LAN port dongle, a large software bundle is also included in the big box. It contains programs for Web design or photo editing as well as compression and archiving software. Currently there is unfortunately no matching port replicator for the U772 online, but will likely be available soon.
Maintenance
There are no visible screws on the Lifebook U772 and thus you cannot access the hardware on your own. Consequently, it is not possible to upgrade or exchange anything later, which is too bad.
Warranty
Fujitsu grants a standard 24-month warranty on the U772's proper functionality. A 5-year warranty extension including bring-in service costs a reasonable 65 Euros (~$82). In return, the 5-year on-site service costs a steep 290.60 Euros (~$366).
通讯
的U772被证明是通信渴望。当然，你可以不仅通过RJ45加密狗连接到有线局域网，但也通过无线WLAN（B / G / N - 2×2迅驰6205N）或UMTS（3000）Sierra Wireless的戈壁。英特尔的WLAN解决方案还支持独有的无线显示技术，屏幕内容传送到显示器/投影机/平板的屏幕，支持这项技术，无需电缆。蓝牙4.0也是在船上，并覆盖由一个专门的博通的模块（BCM207002）。
安全
在这里没有一半的措施。除了上述端口的笔记本电脑锁，TPM（可信平台模块）以及安装了指纹识别器，位于腕托的右下角，因而不能打字时不小心被启用。除了这些特点，它也有可能加密硬盘内容。确保此ultrabook的安全性。
饰品
除了从用户手册，PSU和上述的小型LAN口加密狗，一个大的软件包中还包括大箱子。它包含网页设计或照片编辑以及压缩和归档软件的程序。目前，遗憾的是，没有匹配的端口复制的U772线上的，但可能会很快面市。
保养
富士通LifeBook U772是不可见的螺丝，因此你无法访问自己的硬件上。因此，它是不可能的升级或更换任何东西后，这是太糟糕了。
保
富士通授予标准的24个月的保修期U772的正常功能。 5年保修期延长带来的服务成本合理的65欧元（约82美元）。作为回报，5年的现场服务成本陡峭的290.60欧元（约$366）。
Input Devices
Keyboard
The U772 is extremely slim. Regrettably Fujitsu doesn't stop at nothing in the case of the keyboard. The first thing we noticed was the stiff keys with a very low stroke and poor feedback while typing.
Actually, the problem is quite logical: When a laptop has such a slim design, there is not much room left for the key drop beside the electronics and results in a key drop of just one millimeter (see picture below). The pressure point is just as inferior. The resistance is sometimes more and sometimes less palpable. But you never get a clear, haptic feedback whether the key was really hit. You also have to strike the keys with relatively high force.
This phenomenon is especially noticed in the space bar. When not enough pressure is applied somewhere in the center third, the chances are that the keystroke will not be accepted immediately at the first try. We thus found ourselves returning to our old, forceful typing habits while typing this review and simply pounded on every key in a hit and miss style known from keyboards of the 90s - however, we did not make as many typos then and our fingers did not ache as much due to the longer keystroke.
So the keyboard requires a very accurate and forceful typing style. A few users will likely not have as many problems in making correct inputs, but others will definitely have to reckon with a familiarization period at the beginning. The testers did not take a liking to typing on the keyboard even after extensive writing. In cases of doubt we would advise trying out the keyboard before buying.
键盘
U772是非常渺茫。遗憾的是，富士通并没有停止在什么的情况下的键盘。我们注意到的第一件事情是一个非常低的中风和不良反馈的硬键，同时打字。
其实，这个问题是很合乎逻辑的：当一台笔记本电脑有这样的超薄设计，没有太多的余地的主要下拉旁边的电子和结果的关键下降一个毫米（见下图）。压力点是一样的劣势。的阻力，有时多有时少情溢于言表。但是你从来没有得到一个明确的，触觉反馈的关键是是否真的打。您还可以取得相对高力的关键。
这种现象特别是注意到在空格键。当没有足够的施加压力的地方，在中央第三，机会是不会被接受的按键，立刻在第一次尝试。因此，我们发现自己回到旧的，有力的打字习惯，而输入这项检讨，并简单地拍打在一个碰运气的风格而著称，从90年代的键盘每个键 - 但是，我们并没有让尽可能多的错别字，然后和我们的手指没有疼痛尽可能多的时间越长按键。
因此，键盘需要一个非常准确，有力的打字风格。有些使用者可能会没有作出正确的输入，很多问题，但其他人将肯定有不可忽视的一个熟悉期开始。测试人员不喜欢在键盘上打字，即使经过广泛的写作。在有疑问的情况下，我们建议在购买前尝试键盘。
Touchpad
The installed mouse replacement's accuracy is acceptable but can only be called middling. The surface is more smooth than rough and thus the fingers stick only occasionally.
However, the touchpad buttons certainly have to be criticized. They are, like in other modern ultrabooks, no longer dedicated and separated but are in the marked area of the touchpad itself. The keyboard's phenomenon is again found here. The pressure point is too stiff and when the button clicks, the stroke is only detected when the center is hit. Our reaction to this was that we simply placed our thumb in the center. But be careful!: This leads to erroneous entries since all too often a left click is translated as a right-click and vice versa here. Multi-touch gestures cannot be enabled in the lower right task bar in state of delivery as is usual. It is only possible indirectly via the driver menu. However, all current multi-touch gestures, such as the popular two-finger scroll, work fairly accurately.
What good touchpads could look like - and also should in our opinion - is seen in many colleagues, e.g. the Zenbooks UX31A and UX32VD. But even the U310 and U410 Ideapads, cheaper by about 300 to 500 Euros (~$378 to $630), have good input devices installed despite their much lower price.
触摸板
已安装的鼠标替代的精度是可以接受的，但只能被称为中等。表面更加光滑比粗糙的手指粘只是偶尔。
不过，触摸板的按键肯定要批评。 ，像其他现代ultrabooks，他们不再致力于分开，但在标记区域的触摸板本身。键盘的现象再次在这里找到。的压力点是过于僵硬，当按钮按下时，被击中的行程时，仅检测中心。我们的反应是，我们只是把我们的经验，在中心。但要小心：这将导致错误的条目，因为常常被翻译成左击单击鼠标右键，反之亦然。多点触控手势，可以在右下角任务栏状态交货通常无法启用。这是唯一可能间接地通过驱动程序菜单。但是，目前所有的多点触摸手势，如目前流行的双指滚动，工作相当准确。
有什么好处触摸板的样子 - 也应该 - 在我们看来，在很多同事看到，例如： Zenbooks UX31A UX32VD。但是，即使是U310和U410 Ideapads的，由约300至500欧元（约$378至$ 630）便宜，具有良好的输入设备安装，尽管他们的价格要低得多。
Display
Fujitsu's idea to simply install a virtually frameless 14-inch screen in a 13-inch chassis apparently works well and looks good. It is naturally not really a frameless screen because 8 mm (0.3 inches) still separates the TN screen from the air. However, a protective layer over the display suggests an even bigger screen.
Unfortunately, the screen cannot technically compete with similarly expensive contenders due to a resolution of 1366x768. They often rely on a much higher resolution and somewhat well-illuminated screens, for example Samsung's Series 9 900X3B (1600x900) or Asus' Zenbook UX31A (1920x1080).
富士通的想法只是一台13英寸的机箱中安装一个14英寸的屏幕几乎无框显然是行之有效的，看起来不错。这自然不是一个真正的无框屏幕，因为8毫米（0.3英寸）仍然从空气中分离的TN屏。然而，保护层在整个显示表明一个更大的屏幕。
遗憾的是，屏幕可以不是技术上的竞争同样昂贵的竞争者，分辨率为1366x768。他们往往依赖于一个更高的分辨率，有点照屏幕，例如三星的9系列900X3B（1600×900）或华硕的：ZENBOOK UX31A（1920×1080）。

So as to the screen's technical capabilities (LG screen: LP140WH6-TS3), we can confidently speak of merely average quality. Subjectively, the representation is acceptable although it does not display really crisp colors or great contrast rates. The screen is at least matte. Nevertheless, it is not perfect for outdoor use due to the maximum average brightness of 191.4 cd/m2.
The screen responds to viewing angle changes as expected from a TN screen. Although there are no coarse color deviations seen over a long span horizontally, the colors fade when the vertical viewing angle is adjusted only moderately.
The reproduced color spectrum also does not reach the sRGB gamut as expected. The much higher resolution and brighter contenders do not manage this either. However, they are recommended for outdoor use, which is more interesting than the covered color space for ultrabook users. Graphic designers will turn to other, specialized devices anyway.
The Lifebook U772 is usually sufficiently bright for indoor and outdoor use in the shade. Subjectively, we can only criticize the occasionally slightly pixelated reproduction caused by the low resolution and the lack of overview besides the poor brightness after our check. Otherwise, the screen is absolutely sufficient for Internet browsing or office applications. Nevertheless, we think it’s too bad that Fujitsu does not completely exhaust the potential for an absolutely unique selling point in the U772 here.
因此，屏幕的技术能力（LG屏LP140WH6-TS3），我们可以理直气壮地讲，仅仅是平均质量。主观上，表示是可以接受的，虽然它不显示非常明快的色彩或巨大的反差。屏幕至少是磨砂。然而，这是不适合户外使用时的最大平均亮度为191.4流明。
屏幕响应视角的变化，预计从TN屏。虽然没有粗大的颜色偏差看到了大跨度水平，颜色褪色时，垂直可视角度只有适度的调整。
再现的彩色光谱也没有达到预期的sRGB色域作为。更高的分辨率和更光明的竞争者不管理。然而，他们推荐用于户外使用时，这是更有趣的比ultrabook的用户覆盖的颜色空间。平面设计师将转向其他专用设备了。
富士通LifeBook U772通常是足够明亮的室内和室外使用在阴凉处。从主观上说，我们只能批评所造成的分辨率低，缺乏概述除了亮度不佳的支票后，我们偶尔稍微像素化的再现。否则，上网浏览或办公应用程序的屏幕是绝对足够的。不过，我们认为这是太糟糕了，富士通并没有完全耗尽的潜力，绝对是独一无二的卖点U772在这里。
Performance
Judging from only the components, the Lifebook U772 should be a really swift ultrabook. The combination of a speedy SSD storage device (Micron C400, 128 GB - identical with Crucial's M4), Intel's new Ivy Bridge Core i5-3427U processor and 2 x 2 GB of DDR3 RAM (1600 MHz, also from Micron).
And in fact, the Lifebook makes an extremely fast subjective impression in our test. No interruptions or unwanted breaks are seen even in energy-savings mode; all inputs are accepted and implemented immediately. But we definitely do not rely on our gut feeling in the performance test and look at the measured results in detail.
富士通LifeBook U772只从成分来看，应该是一个非常迅速的ultrabook的。一个快速的SSD存储设备的结合，美光（Micron C400，128 GB - Crucial的M4相同），英特尔的新Ivy Bridge的酷睿i5-3427U处理器和2×2 GB DDR3内存（1600兆赫，也从微米）。
而事实上，富士通LifeBook一个非常快速的主观印象，在我们的测试中。无中断或不必要的中断，即使在能源节约模式，所有投入都将接受并立即执行。但是，我们绝对不依赖于我们的内心感觉在性能测试和详细的测量结果。
Processor
Like in other modern ultrabooks, an energy-saving ULV (Ultra Low Voltage) processor from Intel's latest Ivy Bridge generation is used in the Lifebook U772 (TDP: 17 Watts). The Core i5-3427U features a default clock of 2 x 1.8 GHz in addition to the Turbo Boost 2.0 technology that can accelerate single cores up to 2 x 2.8 GHz according to the load. Hyperthreading is also on board and enables processing two threads on one core per clock cycle at the same time. In particular, highly parallelized applications, such as video editing, benefit from this.
The Lifebook U772 is usually on a par with the competition. For example, it is only 1% behind the Zenbook UX32VD in Cinebench R11.5 (multithread), which however uses a weaker processor. It is also neck and neck in Cinebench R10 (64-bit single). The 13-inch MacBook Air is also only 1% faster here. However, when compared with the faster Zenbook UX32VD, it is 9% slower. Of course, their cheaper processor does not support the Lifebook's somewhat higher Turbo Boost, which is important in the single-core benchmarks. Samsung's 900X3B even lags behind by 29% due to the installed, outdated Sandy Bridge processor (CPU: Core i5-2467M, GPU: HD Graphics 3000).
The processor installed in the Lifebook thus always works very fast.
处理器
像其他现代ultrabooks，节能ULV（超低电压）处理器采用的是英特尔最新的Ivy Bridge的新一代富士通LifeBook U772（TDP17瓦）。酷睿i5-3427U的默认频率为2×1.8 GHz的Turbo Boost 2.0技术，可加快到2个2.8 GHz的单核根据负载。超线程是在船上，使一个核心每时钟周期处理两个线程在同一时间。特别地，高度并行化的应用程序，如视频编辑，受益于这种。
富士通LifeBook U772是通常在面值的竞争。例如，它是背后的ZENBOOK UX32VD Cinebench里R11.5（多线程），但使用较弱的处理器中只有1％。这也是在CINEBENCH R10（64位单）并驾齐驱。 13英寸的MacBook Air也只有1％的速度在这里。然而，当与更快的ZENBOOK UX32VD相比，它是慢了9％。当然，他们更便宜的处理器不支持富士通LifeBook略高睿频加速，这是非常重要的，在单核心基准。三星的的900X3B，甚至落后于29％，由于安装的，过时的Sandy Bridge的处理器（CPU：酷睿i5-2467M，GPU：HD显卡3000）。
安装的处理器富士通LifeBook从而始终工作速度非常快。
System Performance
To test the system's speed in real-world conditions, we use Futuremark's PCMark Vantage and PCMark 7. The Lifebook U772 fares quite well owing to the installed SSD and swift processor. For example, the Zenbook UX32VD (Core i5-3317U / GeForce GT 620M) does not stand a chance against our test device due to the conventional magnetic hard disk that is only "boosted" by a small SSD in PCMark Vantage (47% lower result). However, the dispersion is reduced when only looking at the contenders based on SSDs. The Zenbook UX31A (Core i5-3317U / HD Graphics 4000) achieves a 4% lower score and the 13-inch MacBook Air using the same CPU & GPU achieves a 9% better result than our Lifebook.
Our test device scores very well in PCMark 7 and even manages the 7th overall place of all previously tested laptops at the time of the test. The Zenbook UX31A is 2% faster, the MacBook Air 13-inch is 17% slower and Samsung's 900X3B is even 28% slower than the U772. The latter, featuring the Core i5-2467, however still relies on an obsolete processor including an equally obsolete, integrated graphics (HD Graphics 3000).
The overall system performance assessed using various benchmarks can thus also be called excellent.
系统性能
为了测试系统的速度在现实世界中的情况下，我们使用Futuremark的PCMark Vantage的和PCMark7。富士通LifeBook U772的票价相当不错由于安装SSD和迅速的处理器。例如，的ZENBOOK UX32VD的（酷睿i5-3317U/的GeForce GT620M）不会有机会对我们的测试设备，由于传统的磁性硬盘，这只是一个小的SSD在PCMark Vantage（低47％的结果“增强型”）。然而，分散降低时，只有基于固态硬盘的竞争者。的：ZENBOOK UX31A（酷睿i5-3317U/ HD图形4000）达到4％的低得分和13英寸的MacBook Air使用相同的CPU和GPU实现更好的结果比我们的LifeBook9％。
我们的测试设备在PCMark7的成绩非常好，甚至在测试的时候，管理的第7顺位之前测试过的笔记本电脑。 ，ZENBOOK UX31A是2％的速度，在MacBook Air13英寸慢为17％和三星900X3B甚至是28％，比U772慢。后者，配备了酷睿i5-2467的，但是仍然依赖于过时的处理器，包括同样过时的，集成显卡（HD3000图形）。
使用不同的基准评估系统的整体性能，因此也可以被称为优秀。

Storage Devices
So the overall performance is excellent. This is also largely due to the installed SSD. Micron's new C400 SSD has a capacity of 128 GB in our test device. However, the user can only use approximately 30 GB effectively after the operating system and important software has been installed. After installing all kinds of benchmarks and the listed games, we have only roughly 24.5 GB left over.
Looking at the test results of CrystalDiskMark, the SSD does a flawless job. Large amounts of data are accessed extremely fast with 451 MB/s in sequential read. The 13-inch MacBook Air using the same CPU/GPU also presents the same result in this test, but the Zenbook UX31A (i5-3317U / HD Graphics 4000) scores 6% better. Whether this slight difference is really noticed in routine use is doubtful.
However, flash-powered storage devices excel in reading small files (for example, booting the operating system or programs) compared with conventional hard disks. CrystalDiskMark's 4K read benchmark provides information about exactly this scenario. Here, a very good 22.6 MB/s is reached, but the Zenbook UX31A is again faster with 28.3 MB/s. Our test device manages an excellent 7th overall place in the 4KQD32 test and is thus the absolutely fastest ultrabook of the ultrabooks we reviewed here. It surpasses its immediate pursuer, Samsung's 900X3B (Core i5-2467M / HD Graphics 3000), by 9%. The MacBook Air 13-inch is even defeated by 55%.
The installed SSD is very fast (this is illustrated by the AS SSD benchmark on the right). Fujitsu may commend Micron as a manufacturer for this because it is doubtlessly the reason for the excellent system performance we observed.
存储设备
因此，整体表现非常出色。这也主要是由于安装的SSD。美光新推出的C400 SSD的容量为128 GB，在我们的测试设备。但是，用户只能使用约30 GB操作系统后有效和重要的软件已经安装。安装完成后各种基准和上市的游戏中，我们只有大约24.5 GB遗留下来的。
在CrystalDiskMark的测试结果看，SSD做一个完美无瑕工作。顺序读取451 MB/ s的速度非常快，大量的数据访问。在这个测试中，13英寸的MacBook Air使用相同的CPU / GPU也提出了相同的结果，但的：ZENBOOK UX31A（酷睿i5-3317U/ HD图形4000）6％的成绩更好。无论是在日常使用中真正注意到这细微的差别是值得怀疑的。
然而，闪存驱动存储设备，擅长阅读与传统硬盘相比，小文件（例如，启动操作系统或程序）。 CrystalDiskMark的4K读取基准的正是这种情况的信息。在这里，一个很好的22.6 MB/ s的到达，但ZENBOOK UX31A再快28.3 MB/秒。我们的测试设备管理的一个很好的第7顺位的地方中的4KQD32的测试，因此是绝对速度最快的的ultrabooks我们回顾这里的ultrabook的。它超越了其直接的追求者，三星900X3B（酷睿i5-2467M/ HD3000图形），9％。 MacBook Air的13英寸甚至打败了55％。
安装SSD是非常快的（这说明了在正确的AS SSD Benchmark的）。富士通赞扬美光，因为它作为一个制造商，这无疑是卓越的系统性能的原因，我们观察到。
Graphics Card
Intel's new Ivy Bridge generation includes a shrunken manufacturing process as well as the new integrated graphics solution: the HD Graphics 4000. According to Intel, it should be fast enough to accelerate even several 4K videos simultaneously (at least the desktop variant). The GPU clock of 650 MHz implemented there is however not used in our test device. We found a base clock of 350 GHz.
We believe that this IGP solution is very appropriate for ultrabooks. Since the graphics is integrated in the processor, more energy can be saved than with dedicated GPUs; the performance is now on a par with that of entry-level cards (e.g. GeForce GT 610M) or sometimes is a bit lower. Thus, you can usually enjoy many games smoothly in the lowest settings in addition to all kinds of HD videos.
Compared with the competition, the HD Graphics 4000 in the Lifebook U772 scores a lot worse than the one in the MacBook Air 13-inch, which renders 57% faster with the same processor and consequently the same GPU in 3DMark Vantage. But the Zenbook UX31A is also 21% faster despite a slightly weaker Core i5-3317U and HD Graphics 4000.
However, since the scores of the respective processor benchmarks are generally higher than those of the competition, the results suggest that Fujitsu prioritizes the processor under high load and takes the power from the graphics card to prevent the device from overheating (see screenshots below). This also makes sense in view of the ultrabook's business alignment because you more often benefit from a faster processor than from faster graphics in daily work situations.
图形卡
英特尔的新Ivy Bridge的生成包括一个缩小的制造工艺以及新的集成图形解决方案：高清显卡4000。据英特尔称，它应该是足够快的速度，同时加速甚至几4K影片（至少在桌面上的变体）。然而，在我们的测试设备不使用GPU时钟频率为650 MHz，实施有。我们发现了一个基地的350 GHz的时钟。
我们相信，这IGP解决方案是非常适合ultrabooks。由于图形集成于处理器，更多的能量可以保存比使用专用的GPU（图形处理器）的性能等同于入门级的卡（如GeForce GT610M的），或有时低一点。因此，您通常可以享受许多游戏顺利，除了各种高清视频的最低设置。
随着竞争加剧，高清显卡4000富士通LifeBook U772相比成绩差了很多比MacBook Air的13英寸，这使得57％的速度相同的处理器，因此在3DMark Vantage相同的GPU中的一个。但ZENBOOK UX31A21％的速度尽管稍微弱于酷睿i5-3317U和高清显卡4000。
然而，由于各自的处理器基准测试的分数普遍高于那些在竞争中，结果表明，富士通的优先级处理器在高负载下，并从显卡的电源，以防止设备过热（见下面的截图）。这也是情理之中的Ultrabook的业务调整，因为你常常受益于更快的处理器更快的图形在日常工作中的情况下。

Gaming Performance
We could also only produce a rather below average graphics card performance in the tested games (all bestsellers). However, it is more striking that particularly Fujitsu ultrabooks tend to perform poorly and are the slowest laptops featuring Intel's new graphics solution that we have tested. We relate this to a comparatively poor temperature management and the consequent throttling of these devices (more about that later).
Anno 2070 exhibits smooth playability in low details and a resolution of 1024x768 with an average of 33 frames per second (fps). However, all laptops featuring the same graphics card achieve 17 to 45% faster frame rates. The MacBook Air 13-inch, with the same CPU & GPU and roughly the same settings, manages a much faster 47 fps. We would not recommend higher setting in the Lifebook because, for example, 15 fps do not enable smooth gameplay in medium details and the native resolution of 1366x768.
FIFA 12 looks the same: With 800x600 and low details, the gameplay can be followed with continuously smooth 79 fps. However, the Zenbook UX31A (Core i5-3317U, HD Graphics 4000), for example, is a whole 34% faster with 106 fps than the Lifebook. The game is fairly smooth up to medium details and a resolution of 1024x768 (49 fps). There are noticeable stutters observed in Lifebook's native resolution of 1366x768 and high details including two-time anti-aliasing due to 22 fps.
The atmospheric first-person shooter, Metro 2033, is also part of this test. It even demands quite a bit of effort from high-end systems. Our overburdened Lifebook U772 already displays a jerky presentation of 19 fps at a resolution of 800x600 and low details in DX 9 mode. So a smooth gameplay is not possible on this ultrabook. This is repeated in the result using the native resolution and medium details, where merely 9 frames per second are achieved in DX 10 mode and the game looks like a flip-book.
Verdict: The occasional game is only possible to a point and with limitations. However, if you want to use your laptop more frequently for gaming, the U772 is definitely the wrong piece of hardware.
游戏性能
我们也可以只生产显卡的性能，而低于平均水平测试的游戏（所有畅销书）。然而，更引人注目的，特别是富士通的ultrabooks往往表现不佳，是最慢的笔记本电脑采用英特尔的新的图形解决方案，我们已经测试过。我们涉及到一个相对较低的温度管理和随之而来的节流这些设备（稍后详细说明）。
安诺2070展品顺利可玩性低的细节和分辨率为1024x768，33帧每秒（fps）的平均。然而，所有具有相同的图形卡的笔记本电脑达到17〜45％更快的帧速率。 13英寸的MacBook Air，使用相同的CPU和GPU大致相同的设置，更快的47 fps的管理。我们不推荐富士通LifeBook更高的设置，例如，每秒15帧不使顺畅的进行游戏中的细节和原始分辨率为1366×768。
FIFA 12看起来是一样的：800x600和低细节，游戏应遵循的连续平滑的79帧。然而，在：ZENBOOK UX31A（酷睿i5-3317U，高清显卡4000），例如，比富士通LifeBook 106 fps的速度提高了整体的34％。游戏中的细节和分辨率为1024×768（49 fps）的还算顺利。观察通Lifebook的原生分辨率为1366×768，高的细节，包括两抗锯齿由于22 fps的有明显的口吃。
在大气中的第一人称射击游戏，“地铁2033”，也是本次测试的一部分。它甚至需要相当多的努力，从高端系统。我们不堪重负的LifeBook U772已经显示在一个生涩的表现，19帧，分辨率为800×600和DX 9模式下低细节。因此，一个顺畅的进行游戏是不可能在此ultrabook的。这是重复的结果，使用本机分辨率和介质的详细信息，其中仅仅是9每秒帧数在DX 10模式下实现的，和游戏看起来像倒装书。
结论是：偶尔的游戏是唯一可能的一个点，有限制的。但是，如果你想更频繁地使用你的笔记本电脑游戏，U772的硬件绝对是错误的。

Emissions
System Noise
The U772 is pleasantly continuously quiet during routine use (i.e. Web browsing, word processing, etc.). The fan's noise is even completely canceled for the most part because it is often disabled when not needed. A minor yo-yo effect (regular on and off of the fan) was observed after a longer period of testing in energy-savings mode. However, the frequency between fan and mute phases is longer than usual and is thus not noticed as much as in other laptops.
But when the fan starts up and has a lot to do because of increasing load, the high-pitched whir of the small fan is striking as it desperately tries to discharge the produced waste heat into the surroundings. The device is not very successful in this attempt, which is why we measure a maximum of 40.1 dB(A). Alongside the high frequency, it sounds like a blow dryer. This scenario will unlikely be reached in real-life - providing you do not want to edit videos (we would discourage doing that on this device anyway). The competition cools their ultrabooks with much less noise.
We also noticed that some transistors generate a quiet hum when the PSU is connected to the device. This can get annoying after a long period in quiet surroundings, but is also noticed occasionally in other laptops.
系统噪声
U772是惊喜不断安静，在日常的使用（如网页浏览，文字处理等）。风扇的噪音甚至完全取消，因为它是最经常被禁用时，没有必要。 A小调的溜溜球效应（经常的风扇的开启和关闭），观察了一段时间后在能量节省模式下的测试。然而，风扇和静音阶段之间的频率是比通常更长，因此，没有注意到尽可能在其他的笔记本电脑。
但是，当风扇启动时，有很多这样做，因为不断增加的负载，高亢的呼呼的小风扇是惊人的，因为它拼命地试图释放到周围环境中产生的余热。该设备是非常成功的，在这样的尝试，这就是为什么我们测量最大为40.1分贝（A）。除了高频率，这听起来像一个吹风机。在现实生活中，这种情况将不大可能达到 - 你不想要编辑的视频（我们会阻止这样做，反正在此设备上）。本次大赛冷却他们的ultrabooks噪音少得多。
我们也注意到，一些晶体管生成一个安静的嗡嗡声时，电源连接到设备。经过长时间在安静的环境中，这可以让恼人的，但偶尔也注意到在其他的笔记本电脑。

Temperature
Both the case's top (max. 34.8 °C) as well as the bottom (max. 33.6 °C) stays agreeably cool during low load. Thus, we can reassure all potential buyers who want to use the U772 for office tasks on their lap on the go. However, the fan's unusual air intake location has to be considered. The air intake is located on the bottom's upper left corner on the device - exactly where the left knee would normally be when used on the lap. Although it is never fully covered, the positioning doesn't seem well-considered.
The maximum temperature climbs to 44.7 °C on the top and 44.2 °C on the bottom during tests of longer full loads (Prime95 + FurMark), around the vent in the bottom's upper left corner in both cases. The rest of the ultrabook remains comparatively cool (approximately 33 °C). We now want to investigate the feared throttling, and in fact while Turbo Boost still lifted the processor to 2.1 GHz at the beginning (which is still slower than the competition) it freezes at 798 MHz after an hour of full load. The core temperatures exhibit a fairly hot 82 °C and the fan is now in the aforementioned "blow dryer" mode.
Fujitsu has apparently made cutbacks in cooling design in favor of a particularly slim chassis. We would personally have accepted a bit more weight or component density for a better cooling capacity that could harness the installed hardware in full without slowing it down. But when used in Office mode, these worries are quickly forgotten and, as the benchmarks show, the U772 belongs to the currently fastest devices on the market under these conditions.
温度
在低负荷的情况下的顶部（最大34.8℃），以及底部（最大33.6℃）保持愉快凉爽。因此，我们可以向所有潜在的买家谁想要在旅途中使用U772在他们的腿上办公室的任务。然而，风扇不寻常的进气口位置加以考虑。进气口位于底部的左上角在设备上 - 确切位置，通常是放在膝上使用时，左膝。虽然这是从来没有完全覆盖，定位似乎并没有经过深思熟虑的。
的最高温度爬升至44.7°C上的顶部和44.2℃下，在测试过程中的底部上较长满载（Prime95的+ FurMark进行），周围的通风孔，在这两种情况下的底部的左上角。其余的Ultrabook仍然比较冷（约33°C）。现在我们要调查恐怖的限制，事实上，涡轮增压解除了处理器2.1 GHz的开始（这是仍然慢于竞争对手）冻结后，在798 MHz的一个小时的满负荷。呈现一个相当热的82℃的核心温度和风扇现在是在前面提到的“吹塑机”模式。
富士通已经明显地做了特别薄形机箱散热设计，有利于削减。我们会亲自接受了更多的重量或组件的密度，更好的散热能力，可以利用已安装的硬件完全没有减缓下来。但是，当使用在Office模式，这些忧虑很快被遗忘，作为基准测试显示，U772属于目前市场上速度最快的器件在这些条件下。
(±) The maximum temperature on the upper side is 44.7 °C / 112 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(±) The bottom heats up to a maximum of 44.2 °C / 112 F, compared to the average of 39.4 °C / 103 F
(±) In idle usage, the average temperature for the upper side is 32.1 °C / 90 F, compared to the device average of 30.8 °C / 87 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (33.8 °C / 92.8 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (-5.5 °C / -9.9 F).
Speakers
Fujitsu installs two tiny speakers on the U772's lower right and left edges. They are logically very focused on speech intelligibility (business alignment), which is also successful. However, they are not very loud due to their small size.
Nevertheless, this setting affects music enjoyment. Even the tester's smartphone provides a fuller sound than the Lifebook. We don't expect full bass from slim laptops anyway, but rather a treble-heavy sound. However, our test songs hiss and ring so extremely that it is a relief to connect our external speakers. The produced sound pacifies us again because it is absolutely balanced.
音箱
富士通U772较低的左，右边缘上安装了两个微型扬声器。它们在逻辑上非常注重对语言可懂度业务调整，这也是成功的。然而，他们都不是很大声由于其体积小。
然而，此设置影响的音乐享受。即使测试仪的智能手机提供了一个更全面的声音比富士通LifeBook。反正我们不指望低音超薄笔记本电脑，而是一个高音沉重的声音。然而，我们的测试歌曲的嘶嘶声和环如此极端的，它是一种解脱连接外部扬声器。所产生的声音安抚我们，因为这是绝对平衡的。
Battery Life
Power Consumption
It is very impressive how efficiently our test device manages the required energy. The U772 is content with extremely low 4.4 - 8.7 Watts when idling. The Lifebook surpasses all contenders, but then they have screens with a much higher resolution and brightness.
The 37 Watts produced during full load are a very low consumption rate in the test range of all laptops. Compared with ultrabooks that use integrated graphics, the Lifebook is pretty far back - probably also because of the somewhat larger 14-inch screen that consumes a bit more power in maximum brightness than the smaller contenders.
耗电量
我们的测试设备如何有效地管理所需的能量，这是非常令人印象深刻的。 U772是非常低4.4 - 8.7瓦怠速时的内容。富士通LifeBook超越了所有的竞争者，但后来他们有更高的分辨率和亮度的屏幕。
在满负荷生产的37瓦的消费率是非常低的，在测试范围内的所有笔记本电脑。与的ultrabooks使用集成显卡相比，富士通LifeBook是相当早 - 可能也是因为稍大的14英寸的屏幕，消耗了更多的能源，最大亮度比小的竞争者。

Battery Runtime
We knew that the U772 would deliver good rates during low load, as a result of reading eBooks, even before the test. The Lifebook squeezes a good 9 hours 28 minutes out of the 45.3 Wh battery in the Battery Eater Reader's test with disabled network adapters and Bluetooth, minimum screen brightness and a CPU frequency set to 800 MHz (the Eco button is available for this setting). This is a good rate in the ultrabook sector, but the MacBook Air 13-inch and the Zenbook UX31A surpass this a bit with 10 hours 17 minutes and 10 hours 48 minutes using a 60 Wh battery. Therefore we doubt the manufacturer's specification of "up to 10 hours battery life". It is actually impossible to achieve this time unless you leave the laptop unused in sleep mode with disabled screen.
More interesting is our standardized WLAN browsing test where, as the name indicates, we visit predefined sites on the Web via Wi-Fi using a measured backlight of approximately 150 cd/m2 (among them YouTube HD videos). It supplies us with the best conclusions about how a laptop will behave in real-life. For an ultrabook, the Lifebook U772 manages a good time of 5 hours 17 minutes. Many of the above named contenders remain below 5 hours while the MacBook Air 13-inch lasts for at least 6 hours 3 minutes (even a bit longer using Mac OSX Lion).
The Lifebook lasts for 1 hour and 37 minutes during full load (simulated using maximum brightness, enabled Wi-Fi and Battery Eater Classic test). Both Zenbook contenders are the leaders here, going back to the mains as much an hour later (lasting over 2.5 hours).
Overall, the U772 is energy-efficient and thus reaches a good battery life.
电池运行时间
我们知道，U772将提供良好的价格在低负荷，阅读电子书的结果，甚至在测试之前。富士通LifeBook挤出一个好9小时28分钟出的45.3瓦时电池的电池食阅读器的测试禁用的网络适配器和蓝牙，最低屏幕亮度和一个CPU频率为800兆赫的生态按钮是此设置。在Ultrabook的部门，这是一个很好的速度，但13英寸的MacBook Air和ZENBOOK UX31A超越这一点与10小时17分钟和10小时48分钟，使用一个60瓦时电池。因此，我们怀疑制造商的规格“长达10小时的电池寿命”。它实际上是不可能实现的这个时候，除非你离开笔记本电脑在睡眠模式下，残疾人屏幕未使用的。
更有趣的是，我们的标准的WLAN浏览测试，正如其名称所表明的，我们访问预定义的网站在网络上通过Wi-Fi使用的背光约150 cd/m2的（其中包括YouTube的高清视频）。它为我们提供了一台笔记本电脑将如何在现实生活中表现最好的结论。对于富士通LifeBook U772的Ultrabook，管理一个很好的时间为5小时17分钟。上述命名的竞争者仍低于5小时，而13英寸的MacBook Air持续至少6小时3分钟（甚至更长的时间使用Mac OSX狮子）。
富士通LifeBook持续时间为1小时37分钟，在满负荷（模拟使用最大亮度，使Wi-Fi和电池食经典测试）。这两个ZENBOOK的竞争者是领导人在这里，回水管多小时后（持续时间超过2.5小时）。
总体来说，U772是节能，从而达到良好的电池寿命。
Verdict
Perhaps you experienced similar thoughts while reading this review as we did during the test. First anticipation, because of the extremely attractive, slim and lightweight, yet very stable magnesium chassis. Then the delight about how much hardware finds room in the very tight space - including the 14-inch screen and the UMTS module. Finally the overall excellent build quality, the good and robust hinge that first looks so small, almost fragile, but nevertheless always conveys a really secure feeling when the laptop is opened.
But as sublime as the U772 seems to be, it is not without weaknesses. The 14-inch screen, fitted into a small case where the competition would sooner install a 13-inch display, could have been a unique selling point. However, due to its poor outdoor suitability and the comparatively low resolution, it is ultimately a downer.
Fujitsu seems to have accomplished its goal: one of the slimmest laptops with the most efficient use of space. But it was done without regard to losses. There is no other way that we can explain the rather disappointing keyboard in a business ultrabook. The too short and somewhat stiff keystroke that lacks palpable feedback forces the user to apply a concentrated and forceful typing style. What good are the excellent system performance and the swift storage device when inputting issues slow you down?
也许你经历过类似的想法，而阅读这个检讨，因为我们没有在测试过程中。第一期待，因为非常有吸引力的，超薄超轻，但非常稳定的镁质底盘。多少硬件的喜悦，发现房间非常狭小的空间 - 包括14英寸的屏幕和UMTS模块。最后，整体优良的建设质量，良好和强大的铰链，看起来很小，几乎是脆弱的，但无论如何总是传达出一种真正的安全的感觉，当笔记本电脑被打开。
但作为崇高的U772似乎是，但也不是没有弱点。装成小的情况下，这里的竞争迟早会安装一台13英寸的显示器，14英寸的屏幕，可能是一个独特的卖点。然而，由于其的户外适用性差和相对较低的分辨率，它最终是一个令人沮丧。
富士通似乎已经完成了自己的目标：最有效地利用空间上最薄的笔记本电脑之一。但它没有考虑到损失。有没有其他的方式，我们可以在业务ultrabook的解释令人失望的键盘。过短，按键有点僵硬，缺乏可扪及反馈强制用户应用的集中和有力的打字风格。什么是卓越的系统性能和快捷的存储设备时，输入你慢下来的问题吗？
