东芝 Satellite U940-101 超级本测评
Editor's Note (January 17, 2013): The following review has not yet been edited for grammatical errors. A final draft of the review will be released soon.
For the original German review, see here.
The first ultrabooks were launched more than a year ago. Meanwhile, an impressive variety of models is available, which is continuously enhanced by several manufacturers.
Toshiba also expand their product range and launch the first 14-inch ultrabook. Compared to previous models like the Portégé Z930, the Satellite U940 does not only feature a bigger display, but should also attract price-conscious customers. The entry-level configuration with Core i3 is priced at 700 Euro. Our U940-101 test model is available for about 800 Euro and features a Core i5-3317U, 8 GB RAM and a 640 GB hard drive with 32 GB SSD cache. Its price-performance ratio is excellent, but does this have a negative impact on build quality?
In our review, we will scrutinize the laptop and compare the Satellite to its direct competition. This includes Lenovo's IdeaPad U410 and Dell's Inspiron 14z, which performed excellently in the past.
编者按（2013年1月17日）：下面的审查尚未被编辑语法错误。最后草案的审查将很快被释放。
对于的德国原装审查，在这里看到。
一年多前推出的第一个ultrabooks。同时，一个令人印象深刻的多种型号，这是由几家制造商不断提高。
东芝公司还扩大其产品范围，并推出第一款14英寸Ultrabook。相比以前的型号一样的Portege Z930，卫星U940不仅配备了更大的显示屏，但是也应该吸引对价格敏感的客户。采用酷睿i3入门级配置的售价为700欧元。 U940-101测试模型可为约800欧元和功能的酷睿i5-3317U，8 GB RAM和640 GB硬盘32 GB SSD缓存。它的价格性能比是好的，但有建设质量的负面影响？
在我们的审阅，我们将审议的笔记本电脑，并的卫星直接竞争相比较。这包括联想的IdeaPad U410和戴尔的Inspiron14Z，在过去的表现非常出色。
Case
At the first glance, the Satellite looks like typical ultrabooks with high-quality metallic surfaces. But, when looking closer, you'll realize that it is not made from aluminum. In order to keep the price low, Toshiba instead use significantly cheaper plastics. Besides, the bluish shining U940 looks elegant.
The especially thin display frame (about 14 mm) intensifies this experience. As a result the case looks smaller than many competitors'. The laptop can be easily transported as it weighs barely 1.7 kg and is only 20.7 mm high, although it cannot compete with 13.3 inch laptops in this aspect, as these often even 0.5 cm thinner and several grams lighter.
The omission of solid light metals has a negative impact on the stability. The chassis notably gives in under light pressure at many parts, but this does not have an impact on usability. In addition, the display's torsional stiffness is also just moderate. As with many laptops in this price range, the lid teeters, because the hinges are not high-quality.
Finally, we want to praise the Toshiba's high build quality. Due to small gaps and neatly rounded edges, we cannot criticize much here and, taken as a whole, the Satellite U940 deserves a good rating.
乍看之下，卫星看起来像典型的ultrabooks提供高品质的金属表面。但是，当仔细一看，你就会意识到，它不是由铝合金制成。为了保持低价格，东芝，而不是使用非常便宜的塑料。此外，蓝色的闪亮U940看起来很优雅。
特别薄的显示框（约14毫米），加剧了这方面的经验。作为结果的情况下看起来比许多竞争对手的。笔记本电脑就可以很容易地运输，因为它的重量仅仅1.7公斤，是只有20.7毫米高，虽然不能与13.3英寸的笔记本电脑在这方面的竞争，因为这些往往甚至0.5厘米薄，轻几克。
遗漏了坚实的轻金属的稳定性有负面影响。机箱特别是给出了在许多部分的轻的压力下，但不具有对可用性的影响。此外，显示的是扭转刚度也只是适度。与许多笔记本电脑在这个价位上，盖摇摇欲坠，因为铰链的质量不高。
最后，我们要赞美东芝的建设质量。由于小的差距和整齐的圆边，我们不能批评很多在这里，作为一个整体，卫星U940应该得到很好的评价。
Connectivity
Ultrabooks often offer only few interfaces. Unfortunately, the U940 is not an exception and only delivers standard fare. Peripherals can be connected to a total of three USB ports. Two of them support modern version 3.0. In addition one of the supports "sleep and charge", which allows charging USB devices when the notebooks is turned off.
In addition to Fast Ethernet, it is a pity that the laptops lacks a DisplayPort as well as VGA. External displays can only be attached via HDMI with a maximum resolution of 1080p.
The right side houses most of the ports. So righties might find avoiding disturbing cables more difficult than lefties. Frequently used interfaces like audio jacks and card readers are far at the front and easily accessible.
Ultrabooks往往只提供一些接口。不幸的是，U940也不例外，只提供标准收费。共3个USB端口可以连接到外围设备。其中两个支持现代版本3.0。另外之一的支持“睡眠和充电”，它允许USB设备充电，当笔记本被关闭时。
除了快速以太网，遗憾的是，缺乏一个DisplayPort的笔记本电脑以及VGA。只能连接外部显示器可以通过HDMI，最大分辨率为1080p。
的右侧设有大部分港口。所以右手可能会发现避免令人不安的电缆更加困难比左撇子。音频插孔和读卡器等常用的接口在前面不远，交通方便。
Communication
Toshiba's ultrabook supports Bluetooth 4.0 and WiFi standards IEEE 802.11b/g/n. The WiFi module from Intel is called Centrino Wireless-N 2230 and belongs to the lower mid-range. While the user has to live without compatibility to 5 GHz networks, the module features Wireless Display technology used for wireless transfer of image signals. Transmission range, connection stability and transfer rates (maximum gross transfer rate via two antennas of 300 MBit/s) proved to be typical in our test. Unfortunately, Toshiba does not offer a UMTS module.
The image quality of the built-in web cam is disappointing. The blurred pictures from the 1.0 MP sensor are already very noisy in daylight. Together with the also only moderate mic, it at least allows video chats in sufficient quality.
Accessories
Alike most manufacturers, Toshiba does also not include many accessories, but only the essential things: Apart from the ultrabook there are only a battery, a 45 Watt power supply and a short getting started guide and the warranty information in the box.
Windows 8 64 Bit and some applications and tools, which should ease everyday task, are pre-installed. E.g. the "eco Utility" allows controlling the energy settings and Nero 12 can be used to create backups.
Maintenance
Only few ultrabooks can be opened that easily and extensively as the Satellite U940. The two maintenance hatches on the underside are just screwed down and allow access to the notebook's most important components. Apart from RAM (2 slots, both occupied) and hard drive (1x 2.5 Zoll) also the mSATA drive and the WiFi module can be removed or replaced. In theory, the case can even be further disassembled. However, this is only recommended for technically experienced users.
Warranty
The price includes 2 years international bring-in service or on-site service for customers from Germany and Austria. In addition the warranty can be enhanced for a surcharge of e.g. about 65 Euro (3 years) or 110 Euro (4 years).
通讯
东芝的Ultrabook支持蓝牙4.0和WiFi标准IEEE 802.11b/g/n的。 WIFI模块被称为从英特尔迅驰无线-N 2230，属于低中档。当用户生活在没有到5 GHz网络的兼容性，该模块具有用于无线传输图像信号的无线显示技术。传输范围，连接稳定性和传输速率（最大总经由两个天线300 MBit / s的传输速率）被证明是在我们的测试中的典型。不幸的是，东芝并没有提供一个UMTS模块。
内置的网络摄像头的图像质量是令人失望的。在白天的照片模糊从1.0 MP传感器已经非常嘈杂。一起也只有温和的麦克风，它至少可以让视频聊天足够的质量。
饰品
相同方式大多数制造商，东芝确实也没有包括许多配件，但最根本的东西：除了从ultrabook的是只有一块电池，一个45瓦的电源供应器和一个短的入门指南和保修信息，包装盒中。
Windows 8的64位和一些应用程序和工具，从而简化日常任务，并预先安装。例如“生态实用程序”使您可以控制的能量设置，Nero的12可用于创建备份。
保养
只有极少数的ultrabooks可以打开，很容易和广泛的Satellite U940。两个维修舱口盖在底部拧紧，并允许访问笔记本电脑的最重要的组成部分。除了RAM（，既占用2个插槽）和硬盘驱动器（1个2.5十二分之一），也有mSATA驱动器和WiFi模块，可以移除或更换。从理论上讲，的情况下甚至可以被进一步分解。然而，这仅仅是推荐技术有经验的用户。
保
该价格包括2年的国际带来的服务或上门服务的客户来自德国和奥地利。此外，保修的附加费，如可以提高约65欧元（3年）或110欧元（4年）。
Input Devices
Keyboard
Unfortunately, Toshiba did not use the additional space of the 14 inch case and incorporated a keyboard similar to their smaller ultrabooks'. Nevertheless, the alphanumeric keys of the Chiclet keyboard are with 15 mm side length sufficiently big. In addition, we appreciate the keyboard backlight with two brightness levels. It is somewhat unusual that the special functions are assigned to the F-keys as primary function (F1-F12 via Fn-key). Otherwise the layout conforms to the usual standard.
In our test, we had to get used to the extremely short key travel first. Together with the spongy pressure point the typing experience lacks precise feedback. In addition the stability should be improved, but we like the low noise. Similarly expensive competitors from Dell and Lenovo perform better here.
Touchpad
The 10 x 6.5 cm touchpad stems from Synaptics and supports many multi touch gestures with up to four fingers. The smooth surface features excellent gliding traits and precisely reacts to user input without delays. If you dislike arbitrary movements of the mouse pointer while typing, you can simply deactivate the touchpad by pressing F5.
Toshiba use a Clickpad, whose mouse buttons are directly beneath the front part of the surface. Although the feedback could be crispier, quality experience and build quality are overall satisfying.
键盘
不幸的是，东芝没有使用额外的空间，在14英寸的情况下，并纳入其较小ultrabooks'类似键盘。然而，15毫米边长够大的Chiclet键盘，字母数字键。此外，我们对此表示赞赏键盘背光与两个亮度等级。这是有点不寻常的特殊功能，被分配到F-键的主要功能，通过Fn键（F1-F12）。否则，布局符合通常的标准。
在我们的测试中，我们习惯于在极短的按键行程。再加上海绵压力点的打字经验缺乏精确的反馈。此外，应提高稳定性，但我们喜欢的低噪音。同样昂贵的竞争对手戴尔和联想在这里有更好的表现。
触摸板
10 x 6.5厘米触摸板源于Synaptics和支持多种多点触控，最多可以四根手指的手势。光滑的表面具有优异的滑翔特征，正是无延迟，响应用户输入。而打字时，如果你不喜欢的鼠标指针的任意升降，您可以简单地按F5键关闭触摸板。
东芝使用的ClickPad，其鼠标按钮的正下方的前部表面。虽然反馈可能是楷书和优质的体验和建设质量的总体满意。
Display
While more and more high-end ultrabooks feature touchscreens and especially high resolutions (Full HD and higher), the cheap Satellite U940 does neither. The 14 inch display of our test sample only delivers a poor resolution of 1,366 x 768 pixels, which was to be expected in this price range. However, the resulting pixel density of 112 dpi is on par with the Dell and Lenovo, but limits the screen real estate.
The internal screen is a TruBrite display. We measured the brightness in 9 segments and calculated an average brightness of 220 cd/m², which is only good mid-range. Please note, reflective screens as in our test sample should be brighter than matte displays (see outdoor usage below). Furthermore, a slightly darker area is visible along the bottom of the screen, but this is not really disturbing.
虽然越来越多的高端的ultrabooks配备了触摸屏和特别高的分辨率（全高清及更高版本），便宜的卫星U940都不是。我们的测试样本的14英寸显示器只提供了分辨率为1366×768像素，在这个价位上，这是可预期的差。然而，由此产生的像素密度为112 dpi的分辨率是等同于戴尔和联想，但限制了屏幕房地产。
内部屏幕是一个TruBrite显示。我们在9段测得的亮度和计算的平均亮度220坎德拉/平方米，这是唯一的好中档。请注意，在我们的测试样品的反射屏的亮度比磨砂显示（见下面的户外使用）。此外，稍深的区域沿屏幕底部的是可见的，但是这是不是真的令人不安。

Brightness Distribution: 78 %
Center on Battery: 181 cd/m²
Contrast: 210:1 (Black: 1.12 cd/m²)36.17% AdobeRGB 1998 (Argyll 2.2.0 3D)
52.7% sRGB (Argyll 2.2.0 3D)
35.01% Display P3 (Argyll 2.2.0 3D)
The internal screen (140AT20-T02) is based on TN technology and its quality is rather poor. The contrast ratio of 210:1 and the black value of 1.12 cd/m² are standard in this notebook category, but are outperformed be high-end IPS panels like the one used in Asus' Zenbook UX31A. So, videos and games do not look that crisp and vivid. As so often, you need to spend more money for better solutions.
As expected the Satellite U940 is only fit for professional graphics applications to some extend, as it notably misses important standards like AdobeRGB (about 36 % coverage) or RGB (about 53 % coverage). In addition, the color deviation is high ex factory (bluish even after calibration). But, the typical user will hardly notice this.
内部的屏幕（140AT20-T02）是基于TN技术，它的质量是比较差的。在这个笔记本类，210:1的对比度和黑色值的1.12 cd /m²的标准，但跑赢使用的在华硕ZENBOOK UX31A，像一个是高端的IPS面板。因此，视频和游戏不看，清晰和生动。由于这样的时候，你需要花更多的钱，更好的解决方案。
正如预期的那样，卫星U940只适合专业图形应用程序的一些扩展，因为它显着的AdobeRGB（约36％覆盖）或RGB（约53％的覆盖率）错过重要的标准，如。此外，颜色的偏差是在出厂前高（偏蓝即使校准后）。但是，普通用户很难注意到这一点。
As already mentioned above, Toshiba uses a so-called glare-type display with reflective surface. As a result colors look more saturated, but it also brings about negative impacts in many other scenarios: E.g. the notebook can only be used outdoors to some extent. Furthermore, the brightness even falls by about 20% on battery. So, the user should better stay inside at his desk.
正如上面已经提到的，东芝使用一个所谓的防眩光型显示与反射表面。因此，颜色看起来更饱和，但它同时也带来了负面影响，在许多其他情况下，例如：笔记本计算机只能在一定程度上在室外使用。此外，亮度甚至落在对电池的约20％。因此，用户应该更好地留在他的办公桌内。
As a typical TN panel it suffers from narrow viewing angles. Especially when viewed from above, the screen content looks distorted. But, you can move up to 30 degrees in vertical direction without experiencing negative effects. Once the viewing angles is even more acute-angled, the image quality quickly decreases here, too.
作为一个典型的TN面板，它存在视角窄。特别是当从上方观察时，屏幕上的内容看起来扭曲。但是，你可以移动到30度，在垂直方向上没有出现负面影响。一旦观看角度更是锐角，图像质量迅速降低在这里
Performance
Like all ultrabooks, the Satellite U940 uses a ULV processor from Intel. The Core i5 3317U belongs to today's most popular Ivy Bridge models and performs mid-range. Besides Hyper Threading its two cores also support Turbo Boost, which can increase the base clock of 1.7 GHz to up to 2.6 GHz depending on temperature and power consumption. Thanks to the modern 22 nm lithography, it features a low power consumption of 17 Watt. A detailed description of the Core i5-3317U and its Haswell successor expected for Q2 are available in our news and our technical articles.
Every Ivy Bridge CPU houses an integrated graphics chip. The HD Graphics 4000 supports DirectX 11. Thanks to its 16 Executions Units (EU) clocked at 350 to 1050 MHz in the i5-3317U, it delivers a performance on par with dedicated entry-level graphics cards.
The memory capacity of the Satellite is notable. Apart from 8 GB RAM in two 4 GB DDR3-1600 modules, the buyer will also be pleased about a big 640 GB hard drive, which is supported by an additional SSD cache with 32 GB capacity.
像所有的ultrabooks，卫星U940采用的是来自英特尔的ULV处理器。酷睿i5的3317U属于当今最流行的Ivy Bridge的型号和执行范围中。除了超线程（HT），它的两个核心也支持Turbo Boost，可以增加基准时钟为1.7 GHz至2.6 GHz，取决于温度和功耗。由于现代化的22纳米光刻技术，它的特点是低功耗17瓦。酷睿i5-3317U和Haswell的继任者预期第2季的详细说明可在我们的新闻和技术文章。
每个Ivy Bridge的CPU，设有一个集成的图形芯片。高清显卡4000支持DirectX 11。由于其16个执行单元（EU）采用了主频的酷睿i5-3317U在350至1050 MHz的，它提供了一个专用的入门级显卡的性能看齐。
卫星的内存容量是显着的。除了8 GB RAM，2个4 GB DDR3-1600模块，买方也可以高兴一个大的640 GB硬盘驱动器，这是一个额外的SSD缓存支持32 GB的容量。
Processor
If ULV lets you think of slow energy saving models from past years, you are wrong: The Core i5-3317U performs decently and is capable of more than web surfing and office tasks.
In Cinebench R11.5 (64 Bit) the frugal dual core CPU achieves 2.4 points and is about 15 % slower than the 35 Watt Core i5 3210M model. Only the significantly more expensive i7 3517U performs equally much better. In practice the difference should not be noticeable. Just those who frequently edit HD videos or high-resolution images or execute other CPU-intensive task, should consider a faster notebook with quad core CPU. E.g. the Core i7 3630QM is about twice as fast in multi-threading tasks, but cannot be used in slim ultrabooks like the U940.

Mass storage
While SSDs are very fast, they are also small and expensive. In order to combine the speed of flash memory with the capacity of a conventional hard drive, several manufacturers use cache solutions. Here two drives work in a special RAID connection, which automatically moves frequently used programs to the SSD.
Toshiba use a 640 GB hard drive from Hitachi (Travelstar series, 5.400 rpm) and a 32 GB mSATA SSD from Samsung (PM830 series) for such a hybrid solution. It is difficult to measure the resulting performance with conventional tools: Depending on the media currently accessed, transfer rates and the access times vary from very fast to slow. But, OS, browser and other important applications definitely profit from the dedicated cache.
虽然固态硬盘的速度非常快，他们还小，价格昂贵。为了结合与一个传统的硬盘驱动器的容量的闪速存储器的速度，一些制造商使用高速缓存的解决方案。这里有两个驱动器工作在一个特殊的RAID连接，它会自动将经常使用的程序的SSD。
东芝使用640 GB的硬盘驱动器从日立的Travelstar系列（5.400 RPM）和32 GB的mSATA SSD三星（PM830系列），这样一个混合的解决方案。这是很难用传统工具测量得到的性能：根据目前的媒体访问，传输速率和访问时间的变化非常快的慢。但是，操作系统，浏览器和其它重要的应用绝对利润从专用缓存。
System Performance
The PCMark 7 benchmark indicates how well our system with SSD and HDD performs. In achieving astonishing 4,300 points the Satellite U940 even outperforms the Inspiron 14z although the later is equipped with a fully fledged SSD. But, this result should not necessarily be generalized: Apparently the test sequences of the PCMark nearly exclusively used the mSATA SSD, which will not always be the case in practice. If you always demand full performance, you won't be happy with a cache solution in the long run. Everybody else will appreciate the great compromise of price and performance.
7的PCMark基准测试表明我们的系统如何与SSD和HDD的性能。在达到惊人的4300点的Satellite U940甚至超过了Inspiron14Z虽然后来都配有一个完全成熟的SSD。但是，这样的结果应该不一定一概而论：显然的PCMark几乎完全使用的mSATA SSD，这将不总是这样的情况在实践中的测试序列。如果你总是要求完全的表现，你也不会开心的高速缓存解决方案，从长远来看。其他人都将体会到很大的让步，在价格和性能。

Graphics Card
Intel's HD Graphics 4000 does not only decode and encode videos (via quick sync), but can also run simple 3D tasks. Thanks to fast RAM access via dual channel mode, the U940 efficiently uses the potential of the graphics card and achieves 642 points in 3DMark 11. Here, it is on par with the GeForce 610M in Lenovo's IdeaPad U410 (654 points), but about 30 % slower than the Radeon HD 7570M in Dell's Inspiron 14z (908 points). The HD 4000 even performs better in older benchmarks of the 3DMark series, as they depend more on CPU performance.

Gaming Performance
As is already known from former tests, the HD Graphics 4000 can only smoothly run current games in very reduced settings. Nearly all titles are (more or less) playable if you do, although they do no longer look that good.
In Battlefield 3 the user even has to select poor 640 x 480 pixels and the lowest detail level. The game does not even runs smoothly (15 fps) in our preset minimum level (XGA resolution, minimum details) and you really can't enjoy the game this way. Anno 2070, Dishonored, and Diablo 3 are significantly less demanding and run at 30 fps in 1,024 x 768 pixels and low to medium settings. But, as the results prove, adding a weak, dedicated GPU such as in the Lenovo or Dell, would not have been useful. It's a good thing, that Toshiba did not.
高清显卡4000已经从以前的测试中，只可以顺利运行当前游戏在很低的设置。几乎所有的标题是（或多或少）播放的，如果你这样做，虽然他们看上去不再那么好。
在“战地3”的用户，即使选择可怜的640×480像素，最低的细节级别。本场比赛甚至不运行顺利（每秒15帧）在我们预设的最低水平（XGA分辨率，最小的细节），你真的不能享受这样的游戏。安诺2070年，退票，“暗黑破坏神3要求不高，运行在30 fps的1024×768像素，从低到中等设置。但是，结果证明，加入弱，专用GPU，如联想或戴尔，也不会是有益的。这是一个很好的事情，东芝没有。

Emissions
System Noise
Although the fan runs without interruption, the notebook does not get uncomfortably loud while idle. Because of the uniform and low-frequency noise the noise level of 31.6 to 33.8 dB(A) is subjectively very quiet. If you listen closer, hard drive access is audible (32,1 dB(A)), but also only notable in quiet environments.
Under load the noise gradually increases to up to 42.3 dB(A), but the maximum level could only be observed during our stress test. In real life load scenarios, e.g, 3DMark 06, the noise remains on an acceptable level with 37,6 dB(A) and our test sample is as loud as its ultrabook competition.
系统噪声
虽然风扇运行不中断，笔记本电脑不刺耳，而闲置。由于均匀，低频噪声为31.6至33.8分贝（A）的噪音水平是主观上很安静。如果你听的更近，硬盘驱动器访问声音（32.1分贝（A）），但也只有在安静的环境显着。
负载下的噪音逐渐增大到42.3分贝（A），但在我们的压力测试中的最高水平只能观察。在现实生活中负载的情况下，例如，3DMark 06测试，噪音保持在一个可接受的水平，37,6分贝（A）和Ultrabook的竞争，我们的测试样机是一样大声。

Temperature
While idle the top side of the case gets only slightly warmer and only some parts exceed 30 degrees Celsius. With 37 degrees Celsius the underside gets warmer. Nevertheless you can use the U940 on your lap if you just run undemanding tasks like Office or Internet.
Under full load the U940 suffers from its quiet cooling system. While the palm rests remain comfortably cool with a maximum of 34 °C, the temperature increases to 43 to 50 °C around the keyboard. Given the frugal ULV hardware, record-breaking 66 °C on the underside are a surprise. Is throttling bound to occur?
Much to our surprise it is not: During our one hour stress test with Prime95 and FurMark the i5-3317U's core temperatures stay significantly below 80 °C and it keeps running at its base clock of 1.7 GHz. The clock rate of the integrated graphics chip varies between 900 and 1000 MHz and nearly completely uses its Turbo Boost potential. So, throttling should also not occur in summer.
处于闲置状态的情况下得到的顶面略有回暖，只有部分超过摄氏30度。摄氏37度的底部转暖。然而，您可以使用U940放在膝盖上，如果你要求不高的任务，如办公室或互联网运行。
在满负荷U940患有安静的散热系统。虽然掌托保持舒适凉爽，最高34°C，温度上升到43至50°C，键盘周围的。由于节俭的的ULV硬件，破纪录的66条°C的底部是一个惊喜。节流势必会出现吗？
令我们惊讶的是，它是我们在一个小时的压力测试的Prime95的FurMark酷睿i5-3317U的核心温度保持显着低于80°C，并在其基础为1.7 GHz的时钟保持运行。集成显卡的芯片的时钟速率900和1000 MHz之间变化，几乎全部采用Turbo Boost的潜力。因此，节流也应该不会发生在夏季。
(-) The maximum temperature on the upper side is 50.5 °C / 123 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 66 °C / 151 F, compared to the average of 39.4 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 29.1 °C / 84 F, compared to the device average of 30.8 °C / 87 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (34 °C / 93.2 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (-5.7 °C / -10.3 F).
Speakers
The stereo speakers are hidden inside the case and are designed primarily for communication or background sound of videos, but not for music. It lacks bass and mostly also mid tones, while high tones dominate and sound unpleasantly sharp.
If you prefer a better sound and a higher maximum volume, you should either use headphones or external speakers via the decent 3.5 mm jack (tested with AKG K 701) or the digital HDMI interface.
立体声扬声器藏在里面的情况下，主要设计用于通信或视频的背景声音，但不是为了音乐。它缺乏低音和大部分也是中间色调，而高音调占主导地位，听起来令人不快的猛烈。
如果你喜欢一个更好的音质和更高的最大音量时，你应该使用耳机或外部扬声器，通过体面的3.5毫米插孔（测试AKG K 701）或数字HDMI接口。
Energy Management
Power Consumption
The Satellite U940's power consumption is on par with comparably fast ultrabooks. It demands 6.7 to 10.3 Watt while idle and up to 38.1 in 3DMark 06. So, the included 45 Watt power adapter only has a small reserve capacity for charging the battery. In our stress test (not relevant in practice) a maximum of 41.3 Watt is reached.
耗电量
卫星U940的功耗是同等快速ultrabooks看齐。它要求6.7到10.3瓦，空闲时在3DMark06和高达38.1。因此，45瓦电源适配器有一个小的储备能力为电池充电。在我们的压力测试（在实践中不相关）达到最大41.3瓦。

Battery Life
By means of a 45 Wh Li-Ion battery the U940 should be able to reach battery runtimes of up to 4.5 hours according to the manufacturers. However, this value was recorded with Mobile Mark 2012 and not while idle.
The Battery Eater Reader's test (energy saving profile, minimum brightness WLAN off) even reports 6 hours and 27 minutes. That is slightly shorter than the Inspiron 14z's and IdeaPad U410's.
If WiFi is enabled and display brightness is at a medium level (about 150 cd/m²) the runtime falls to about 4 hours. So, the user can work for about half a day remote from an outlet.
As full CPU and GPU performance is also available on battery, the runtime is relatively short in the Battery Eater Classic test. The battery is already empty after 1 hours and 18 minutes and the notebook has to be plugged again. Charging takes about 2 hours.
通过一个45瓦时锂离子电池的U940应该是能够达到长达4.5小时的电池运行时间，按照制造商。但是，该值录得2012年移动标记，而不是在闲置。
电池食阅读器的测试（节能配置，最低亮度WLAN的关闭）报告6小时27分钟。这是比Inspiron越14z和IdeaPad U410稍短。
如果WiFi的启动，和显示器的亮度处于中等水平（约150坎德拉/平方米）的运行时下降到约4小时。因此，用户可连续工作半天遥控器从电源插座。
由于CPU和GPU的性能也可以用电池，运行时间相对较短，电池食经典测试。电池是已经空了1小时18分钟后，，笔记本再次插入。充电时间约2小时。
Verdict
For current laptops barely 800 Euro are not really a small price to pay, however it is for ultrabooks, e.g., because of their high build quality.
The Satellite U940 is not made from expensive light metals. Therefore, the stability of the case is not that high, but the plastics case is neatly manufactured. The money saved here, was invested in powerful hardware, which delivers decent system performance. If you like, you can easily upgrade many components, which is not or only to some extent possible in ultrabook competitors.
As so often, the display is once again one of the biggest points of critique. In this price range, low quality TN panels are commonplace, but the manufacturer should at least have built-in a matte display, so that it stays legible outdoors. As also the battery life is only moderately long, the Satellite unfortunately disappoints a little bit in the key skill of an ultrabook, i.e. mobility.
In addition, the laptop looses points, because its keyboard only has a poor feedback and it gets very hot under load. The later is caused by the slowly rotating fan, which keeps the system noise low. Overall, the Satellite is therefore also not ideal in office use.
Nevertheless, we do not want to say that the U940 is not appropriate for its target group. If you are looking for an especially light and portable laptop with big memory capacities, you could like the slim 14-incher - among others because of its attractive price-performance ratio.
对于目前的笔记本电脑几乎800欧元是不是一个真正的小的代价，但它是ultrabooks，因为他们的高品质。
卫星U940是不是从昂贵的轻金属。因此，稳定的情况下是不高，但被整齐地制造塑料盒。节省下来的钱在这里，在强大的硬件投资，提供了不错的系统性能。如果你愿意，你可以很容易地升级许多组件，这是没有或只有在一定程度上可以在Ultrabook的竞争对手。
正如时候，显示的是再次批判的最大的看点之一。在这个价格范围内，低质量的TN面板是司空见惯，但制造商应至少有内置的雾面显示屏，使其保持清晰的户外。电池的寿命也只有适度的长，不幸的是，卫星令人失望一点点的ultrabook的关键技能，即流动性。
此外，笔记本电脑的丢失点，因为它的键盘有一个贫穷的反馈和负载下，它变得非常热。后缓缓转动的风扇，使系统噪音低造成的。总体而言，卫星在办公室使用，因此也并不理想。
然而，我们不希望说，U940是不适合它的目标群体。如果你正在寻找一个特别轻，便于携带的笔记本电脑，大的内存容量，你可以喜欢苗条的14英寸 - 其中包括因为其极具吸引力的价格性能比。
