Magyar富士通LifeBook A512笔记本测评
For the original German review, see here.
The LifeBook A512 family is a series of affordable office notebooks with 15.6-inch screens. The various models are suitable for both home and business users. Fujitsu has positioned the A512 series in a notebook segment filled with countless devices from a number of manufacturers. In this review we'll see if Fujitsu manages to stick out from the crowd.
For comparison we have chosen the following rivals: Dell Vostro 2520 (Intel Core i3-2328M, Intel HD Graphics 3000) and the Acer TravelMate P253-M (Intel Core i3-2328M, Intel HD Graphics 3000).
对于的德国原装审查，在这里看到。
富士通LifeBook A512系列是一种实惠的办公笔记本电脑，15.6英寸的屏幕。各种型号适合家庭和商业用户。充满了无数的设备，从多家厂商在笔记本电脑领域，富士通定位的A512系列。在这次审查中，我们会看到，如果富士通管理，坚持从人群。
为了便于比较，我们选择了以下的对手：戴尔Vostro成就2520（英特尔酷睿i3-2328M，英特尔高清显卡3000）和宏基TravelMate P253-M（英特尔酷睿i3-2328M，英特尔高清显卡3000）。
Case
The case, housing the hardware of the Fujitsu A512, is made of black plastic. The smooth and matte surfaces indicate that this is a work notebook. The black base unit is partially surrounded by a silver-gray plastic frame. Acer and Dell also utilize plastic cases and similar color schemes.
The case appears well built and quite stable. It can be twisted slightly only in the area of the touchpad. Overall the base unit has a good rigidity. It can hardly be twisted when the display lid is opened. But the lid itself is another story - it can be easily bent. This leads to slight image alterations. The back of the display is more stable. Pressing it does not change the picture. The hinges hold the screen firmly in position and do not allow one-handed opening.
住房的情况下，富士通A512的硬件，黑色塑料制成。光滑的磨砂表面，这是一个工作笔记本。黑色底座单元部分包围一个银灰色的塑料框架。宏碁和戴尔也利用塑料箱及类似的配色方案。
建成并相当稳定的情况下出现。只在区域的触摸板，它可以稍微扭曲。整体的基本单元，具有良好的刚性。显示盖打开时，它也很难被扭曲。但盒盖本身是另一个故事 - 它可以很容易弯曲。导致图像略微改变。显示器的背面更稳定。按下它不会改变图片。按住屏幕的铰链牢牢的位置，并不允许单手打开。
Connectivity
The connectivity equipment of the three notebooks we are comparing is almost identical. There is only one difference - the LifeBook is the only one with an ExpressCard slot (54 mm). Unfortunately, the three notebooks do not have any USB 3.0 ports. Since all of them are aimed at home as well as business users, there should have been at least one such port. Every owner of a large external hard drive would have been grateful. LifeBook owners can use USB 3.0 via an ExpressCard adapter, which costs about 10 Euros (~$14).
The positioning of the USB ports on the A512 is a bit inconvenient. They are located at the front (left and right sides) of the notebook. The Kensington Lock is also located at the front right side of the devices, which is an unusual and impractical place.
我们是在比较的三个笔记本电脑的连接设备几乎是相同的。只有一个区别 - 一个ExpressCard插槽（54毫米）的LifeBook是唯一的一个。不幸的是，这三款笔记本没有任何的USB 3.0端口。由于所有的人都针对于家庭以及商业用户，应该有至少一个这样的端口。每拥有一个大的外部硬盘驱动器会一直心存感激。的LifeBook业主可以通过使用USB3.0 ExpressCard适配器，它的成本约10欧元（约$14）。
在A512上的USB端口的定位有点不方便。它们存在于上面的前部（左侧和右侧）的笔记本电脑。 Kensington锁也位于右前侧的设备，这是一个不寻常的和不切实际的地方。
Communication
Fujitsu has equipped the A512 with an Intel WLAN module (Centrino Wireless-N 2230). It supports the 802.11 b/g/n standards. In addition, it also provides the notebook with Bluetooth 4.0 functionality. The Windows WLAN indicator shows full bars at short distance (3 meters, ~9.84 feet) and at two floors between the router and the notebook (50% transmission power).
The module also supports Intel's Wireless Display technology. This allows a connection between the notebook and a certified display (a TV for example) over WLAN. Displays that do not have WLAN capability can be made compatible with an adapter.
Accessories
The LifeBook comes with a good number of accessories. In addition to the usual leaflets, warranty information and the quick-start pamphlet, Fujitsu has also included three Recovery DVDs (Windows 8 Pro 64 bit, Windows 7 Professional 32 and 64 bit) and two DVDs with drivers (Windows 7 and Windows 8).
Operating System
Our test unit came with a pre-installed Windows 8 Pro (64 Bit). Users who do not want to work with Windows 8 can quickly and easily replace it with Windows 7 via the Recovery DVD. In addition, both systems can easily be installed on a new hard drive. Even Windows XP is still supported and the corresponding drivers can be downloaded from Fujitsu's website.
DVD playback
Microsoft has removed the DVD playback software Windows Media Center from Windows 8. This causes no problems, because the manufacturers have equipped their devices with alternative software. But the LifeBook has no such software pre-installed on Windows 8, thus it cannot play DVDs. When we inquired about this, Fujitsu said that every customer should order the corresponding software (for example PowerDVD; about 10 Euros, ~$14) when choosing Windows 8 as the operating system.
Maintenance
The LifeBook proved to be very maintenance-friendly. The large cover on the bottom of the notebook allows access to the RAM, WLAN module, fan and BIOS battery. The hard drive is located behind a separate cover. The A512 has two RAM slots. Our test unit had one 4 GB module already installed. The notebook supports up to 16 GB of RAM. The fan is completely accessible and can even be removed in order to be cleaned. We liked this feature very much. The hard drive can also be easily replaced. Simply remove the frame, secure the new HDD in it and then install it in the notebook.
Warranty
Fujitsu delivers the A512 with a 12-month Bring-In warranty in some countries. The owners of the P253-M receive more - Acer offers the notebook with a two-year warranty. The warranty period of the Vostro depends on where you buy it from (directly from Dell: one year; other shops: two years). The warranty of the LifeBook and its rivals can be extended. A three year warranty costs about 25 Euros (~$34) and an on-site warranty for the same period costs about 70 to 80 Euros (~$94 to $108).
沟通
富士A512配备英特尔迅驰无线-N 2230无线网络模块（）。它支持802.11 B / G / N标准。此外，它也提供了笔记本与蓝牙4.0功能。在Windows WLAN指示灯显示满格在很短的距离（3米〜9.84英尺），并在两个楼层之间的路由器和笔记本电脑（50％的发射功率）。
该模块还支持英特尔无线显示技术。这使得WLAN的笔记本电脑和认证的显示器（例如电视）之间的连接。不具备WLAN功能的显示适配器可以兼容。
饰品
富士通LifeBook自带的好一些的配件。除了平时的宣传单，保修信息和快速启动的小册子，富士通还包括三个恢复DVD光盘（的Windows 8 Pro的64位Windows 7专业版32位和64位）和两张DVD光盘驱动器（Windows 7和Windows 8） 。
操作系统
我们的测试单元附带一个预装Windows 8专业版（64位）。谁不想与Windows 8的用户可以快速，方便地更换它与Windows 7，通过恢复DVD。此外，这两个系统可以很容易地安装一个新的硬盘驱动器上。即使是Windows XP仍然是支持，可以从富士通网站上下载相应的驱动程序。
DVD播放
微软已经删除了DVD播放软件的Windows Media Center的Windows 8。这不会造成问题，因为厂家都配备了他们的设备的替代软件。但是，有没有这样的LifeBook软件预装在Windows 8，因此，它不能播放DVD。当我们询问，富士通表示，每一位顾客应该购买相应的软件（例如PowerDVD的;约10欧元〜$ 14）选择Windows 8操作系统。
保养
的的LifeBook被证明是非常维修同行。在笔记本电脑底部的大盖允许访问的RAM，无线局域网模块，风扇，BIOS电池。硬盘驱动器位于一个单独的盖后面。 A512有两个内存插槽。我们的测试单元，一个4 GB模块已经安装。笔记本电脑最多可支持到16 GB的RAM。风扇是完全访问，甚至可以进行清洗，以便除去。我们非常喜欢这个功能。硬盘驱动器也可以轻松更换。只需删除帧，确保在新的硬盘驱动器，然后将它安装在笔记本电脑中。
保
富士A512提供12个月把在一些国家的担保。 P253-M的业主得到更多的 - 笔记本与宏碁提供了一个为期两年的保修。保修期为Vostro成就取决于你在哪里买（直接从戴尔：一年;其他店铺：两年）。可以延长保修的LifeBook和它的竞争对手。三年保修费用约25欧元（约$ 34），同期成本约70％至80欧元（约$ 94至$ 108）和现场保修。
Input Devices
Keyboard
The LifeBook comes with a traditional flat keyboard. It also has a number block. The keys are 15 x 16 mm (0.59 x 0.62 inches) in size. They have a good travel and clear pressure point. Users will also be happy about the pleasantly crisp feedback. Unfortunately, the arrow keys are very small and look like they were crammed into the keyboard. The Shift and Tab keys also should have been larger.
Touchpad
The touchpad is 8.5 x 4.2 cm (3.4 x 1.65 inches) large. The smooth surface allows easy finger gliding. The pad supports multi-touch gestures such as two-finger zooming. The two mouse buttons have a short key travel and a clearly audible and tactile pressure point.
键盘
富士通LifeBook配备了传统的平面键盘。它也有若干块。键是15×16毫米（0.59×0.62英寸）的大小。他们有一个良好的旅游和明确的压力点。用户也很乐意有关惊喜脆反馈。不幸的是，方向键是非常小的，看起来像是塞进键盘。 Shift键和Tab键也应该已经较大。
触摸板
触摸板为8.5 x4.2厘米（3.4×1.65英寸）大。光滑的表面可以便于手指滑动。该板支持多点触摸手势，如两个手指的缩放。两个鼠标按钮有一个简短的按键行程和清晰的听觉和触觉的压力点。
Display
Fujitsu has chosen a matte 15.6-inch display for the A512. No other screen options are available. The display surprises us with an acceptable average brightness of 246.1 cd/m². The Vostro (232.8 cd/m²) and the TravelMate (211.1 cd/m²) cannot really keep up here. The brightness distribution, 80% in the Fujitsu, could have been better for all three models.
富士通选择了磨砂A512的15.6英寸显示屏。没有其他屏幕选项可供选择。显示的惊喜我们提供了一个可以接受的平均亮度为246.1坎德拉/平方米。 Vostro成就（232.8坎德拉/平方米）和（211.1坎德拉/平方米）的TravelMate不能真正跟上。所有三个型号的亮度分布，在富士通的80％，本来可以更好。

74.5% sRGB (Argyll 2.2.0 3D)
51.7% Display P3 (Argyll 2.2.0 3D)
The contrast (186:1) and black level (1.49 cd/m²) are worse than the brightness. The display of the Vostro (304:1, 0.84 cd/m²) looks good. The screen of the TravelMate is even better (418:1, 0.56 cd/m²). The display of the A512 cannot cover AdobeRGB or sRGB.
We measured these before the calibration of the display (factory settings). We observed strong DeltaE-2000 deviations in cyan and gray. Subjectively, a blue haze was visible.
对比度（186:1）和黑电平（1.49坎德拉/平方米）比亮度差。 Vostro成就（304:1，0.84坎德拉/平方米），显示效果不错。屏幕的TravelMate甚至更好（418:1，0.56坎德拉/平方米）。 A512的显示不能覆盖AdobeRGB的或sRGB。
我们测量的显示校准前（出厂设置）。我们观察到强2000年的DeltaE青色和灰色的偏差。主观上，蓝色的薄雾可见。
The brightness of the display suffices for outdoor use. Thanks to the matte surface we are spared the reflections. The maximum brightness is fully available on battery power.
显示器的亮度足以适合户外使用。磨砂表面，我们不遗余力的反射。最大亮度上完全可用电池供电。
The viewing angle stability is just what we expected at this price level. A change in the vertical angle quickly leads to image alterations. The horizontal angles are far more generous.
Performance
The Fujitsu LifeBook A512 series are affordable office notebooks for home and business users. Our test model has enough power to complete all the daily tasks required. Word processing, internet browsing and video playback (including HD content) pose no challenge for the notebook.
The various models of the A512 series differ in processor, hard drive size and the operating system. Our model costs 450 to 500 Euros (~$605 to $672). The cheapest version that we could find is equipped with a Pentium B960 and a 500 GB hard drive and comes at a price below 400 Euros (~$538). On average, this model should be about 10% to 20% slower in the various benchmarks. For comparison, we have chosen the similarly equipped notebook Acer Aspire E1-531.
富士通LifeBook A512系列是为家庭和企业用户的实惠的办公笔记本电脑。我们的测试模型有足够的力量来完成所有的日常任务所需。文字处理，网络浏览和视频播放（包括高清内容），为笔记本电脑带来任何挑战。
A512系列产品的各种型号不同的处理器，硬盘驱动器的大小和操作系统。我们的模型花费450至500欧元（约$605至$672）。我们能找到的最便宜的版本，配备了奔腾B960和500 GB硬盘驱动器的价格低于400欧元（约$538）。平均来说，这种模式应该是在各种基准慢约10％至20％。为了便于比较，我们选择了同样配备的笔记本宏碁Aspire E1-531。
Processor
Our test model has a dual-core Intel Core i3-2328M processor, which is of the Sandy Bridge generation. The CPU has a base clock frequency of 2.2 GHz. The Core i3 does not have Turbo Boost. It is practically identical to the Core i3-2330M. The only difference is that the 2328M has Intel's Small Business Advantage Tools. This includes, for example, the option to disable the USB ports.
The Cinebench tests showed the same performance on both AC and battery power. The results of the rival notebooks in the CPU and GL benchmarks are all on a fairly even level. That's not surprising, since these notebooks have the same Core i3-2328M processor with the same HD Graphics 3000 GPU.
我们的测试模型，有一个双核英特尔酷睿i3-2328M处理器，是Sandy Bridge的新一代。 CPU有一个基本时钟频率为2.2 GHz。酷睿i3不具备睿频加速。它实际上是相同的酷睿i3-2330M。唯一的区别是，2328M英特尔的小型企业优势工具。这包括，例如，选项来禁用USB端口。
的Cinebench测试表明在AC电源和电池电源相同的性能。对手的笔记本电脑CPU和GL基准的结果都相当均匀水平。这并不奇怪，因为这些笔记本电脑具有相同的核心酷睿i3-2328M处理器与HD3000 GPU图形相同。

Storage Device
Our notebook comes with a 320 GB Toshiba hard drive that works at 5400 RPM. This hard drive is not among the fastest of its kind. CrystalDiskMark showed a read rate of 84.34 MB/s. HD Tune delivered an average transfer rate of 62.6 MB/s. These are not particularly good scores for a 5400 RPM hard drive. Since the notebook has been designed as an office tool, capacity is not a priority. However, speed is far more important and a Solid State Drive would have worked well for the laptop.
我们的笔记本电脑配备了一个320 GB东芝硬盘工作在5400转。这个硬盘是不是世界上速度最快的同类。 CrystalDiskMark的结果显示为84.34 MB / s的读取速率。 HD Tune的交付平均为62.6 MB / s的传输速率。这些都不是特别好，分数为5400 RPM硬盘。由于笔记本一直作为办公工具，设计容量是不是一个优先事项。然而，速度更为重要，将行之有效的笔记本电脑和固态硬盘。
Graphics Card
The integrated Intel HD Graphics 3000 GPU takes care of the graphics output. It runs at 650 to 1100 MHz and supports DirectX 10.1. There were no surprises with the various 3D benchmarks either. The results are on the expected level. The three notebooks we are comparing had very similar scores due to their almost identical hardware.

Gaming Performance
The LifeBook A512 is definitely not for the demanding gamers. Latest 3D games can be played at most on low resolution and low details. The performance of the HD 3000 suffices only for undemanding games like the FIFA series. Here, stable frame rate was achieved even at the native resolution and medium settings.
富士通LifeBook A512是绝对不为要求苛刻的玩家。最新的3D游戏都可以玩低分辨率和低细节。仅适用于要求不高的游戏，如FIFA系列的性能，HD3000就足够了。在这里，实现稳定的帧速率，即使在原始分辨率和中等设置。
Emissions
Noise Level
In idle state the LifeBook operates silently. We measured a noise level between 30.1 and 33.5 dB. The fan sometimes turns off completely. The Vostro (30.3 to 34.1 dB) shows similar results. The TravelMate (30 to 30.8 dB) is even quieter than the rest. Under medium load (3D Mark 06) the A512 and the TravelMate produced little noise - 33.3 dB. The Vostro on the other hand is significantly louder at 41.3 dB. Under full load (Prime95 and Furmark simultaneously) the LifeBook and the Vostro emit 45.1 dB and 45.9 dB respectively. The TravelMate is significantly quieter at 37.9 dB.

Temperature
The temperatures on the body of the A512 are in the green under any load. At no point was the case too hot and thus the notebook can be used on the lap at any time. At idle, we measured temperatures ranging from 25.8 to 32.7 °C. The Vostro and the TravelMate have very similar temperatures. Under full load (Prime95 and Furmark simultaneously) the A512 heats up to about 25 to 35 °C. The Vostro and the TravelMate show slightly higher temperatures, but both of them are within the acceptable range.
During the stress test on AC power (Prime 95 and Furmark running for at least an hour) the CPU's frequency remained at maximum for about 5 minutes. Then it was throttled to 2.1 GHz. On battery power, the CPU worked at 2.1 GHz during the whole stress test. The GPU finished said test with its maximum frequency (1100 MHz). The temperature of the CPU remained at 72/73 °C.
对身体的A512的温度是在绿色的，在任何负载。在任何时候，太热的情况下，在任何时候，因此，可使用笔记本电脑上一圈。在怠速时，我们测得的温度范围从25.8到32.7°C。Vostro成就的TravelMate有非常相似的温度。在满载情况下（Prime95的和同时的Furmark）A512加热至约25至35℃。 Vostro成就的TravelMate显示温度稍高，但他们都在可接受的范围内。
在交流电源（总理95和至少一个小时的Furmark运行）的压力测试CPU的主频保持在最高约5分钟。然后，它被节流到2.1 GHz。电池供电，工作在2.1 GHz的CPU，在整个压力测试。 GPU成品所述测试，它的最大频率（1100兆赫）。的CPU的温度维持在72/73℃。

(-) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-5 °C / -9 F).
Speakers
The stereo speakers of the LifeBook are located above the keyboard, beneath a mesh cover. They have a thin and tinny sound with poor bass, but movie dialogue is easy to understand. The sound can be adjusted a bit with the help of the pre-installed Realtek HD Audio manager. Those who want a better sound should use headphones or external speakers.
LifeBook立体声扬声器位于键盘上方，下方网罩。他们有一个薄和尖细的声音，低音不好，但电影的对话是很容易理解的。声音可以调整预安装的Realtek HD音频管理器的帮助下，一个位。那些谁想要一个更好的声音，应使用耳机或外部扬声器。
Battery Life
Power Consumption
In idle state the LifeBook draws between 9.4 and 13 W. The TravelMate (7.3 to 10.8 W) is a bit more energy efficient. The Vostro (6.8 to 13.2 W) consumes, depending on the idle usage, slightly less and slightly more than the rivals. Under full load (Prime95 and Furmark), the A512 and the TravelMate are very close with consumptions of 45.6 W and 43.8 W respectively. The Vostro draws significantly more power - 52 W.
耗电量
在闲置状态下的LifeBook吸引9.4和13瓦的TravelMate（7.3〜10.8 W）之间，是有点更高效节能。 Vostro成就（6.8〜13.2 W）消耗，根据闲置的用法，略少，略多于对手。在满载（Prime95测试和Furmark对），A512是非常接近的TravelMate消耗分别为45.6 W和43.8 W。 Vostro成就绘制显着更多的权力 - 52 W。

Battery Life
One battery charge is enough for 6:49 h in idle use. The Vostro 2520 (8:27 h) and the P253-M (7:11 h) last a bit longer. This run time is determined with the help of the Battery Eater Reader's test. The screen brightness is set at minimum, the energy saving profile is on and the wireless modules are turned off. In the full load test the A512 reached a time of 1:18 h and is thus on par with the TravelMate (1:19 h). The Vostro is ahead of the competition, with a run time of 1:33 h. These run times were measured with the Battery Eater Classic test. The screen brightness was set at maximum, high performance profile was chosen and the wireless modules were turned on.
The WLAN test finished after 4:42 h. The TravelMate's score (4:49 h) is on par. The Vostro is again ahead of the rest with a time of 5:24 h. During this test, a script reloads web pages every 40 seconds. The energy saving profile was chosen and the brightness was set at about 150 cd/m². The LifeBook managed 3:21 h in DVD playback. The P253-M lasted only 3:00 h. Once again, the Vostro (5:10 h) shows better results. The DVD test was done with energy saving profile on (or a higher one, if the DVD was not played smoothly), full screen brightness and disabled wireless modules.
The run times of the three notebooks are easy to compare, because their batteries have the same capacity - 48 Wh. It is interesting to see how largely identical devices have very different battery runtimes.
6:49小时一次充电足够在空闲使用。 Vostro成就2520（08:27小时）和P253-M（19:11小时）最后的时间长一点。这个运行时确定的帮助下，的电池噬魂读者的测试。屏幕的亮度被设置为最小值，其节能档案中的无线模块被关闭。在满负荷试验，A512达到1:18ħ的时间，因而是看齐的TravelMate（1:19小时）。 Vostro成就是在竞争中领先的1:33 H的运行时间。这些运行时间进行测量与的电池噬魂经典测试。屏幕亮度设置为最大，选择高的性能配置，并开启无线模块。
的WLAN测试完成4:42 h后。对TRAVELMATE的得分（4时49小时）看齐。 Vostro成就再次领先于其他时间的5:24 H。在这个测试中，一个脚本重新载入网页每40秒。节能配置文件选择亮度设置约150坎德拉/平方米。富士通LifeBook管理3:21小时的DVD播放。 P253-M历时仅3:00 h。再一次的Vostro（5:10小时）显示了较好的结果。 DVD测试做与节能配置文件（或更高的，如果DVD无法顺利播放），全屏亮度和残疾人的无线模块。
三款笔记本的运行时间是比较容易的，因为他们的电池具有相同的容量 - 48瓦。这是有趣的，看看大致相同的设备有非常不同的电池运行时间。
Verdict
The LifeBook A512 offers a good application performance. It also impresses us with its maintenance capabilities and low heat emission. The keyboard is also good and is suitable for longer typing sessions and don't forget the two operating systems including the Recovery DVDs. Criticism goes to the bright, but very low contrast display.
The Vostro 2520 offers users the longest battery life of the three notebooks. In addition you can also order it without an operating system. The TravelMate P253-M is recommended to those users who value low operational noise. Overall, all three notebooks do exactly what they were designed to do. Although they are very similarly equipped, each one excels in a different area.
富士通LifeBook A512提供了良好的应用性能。它也让我们印象深刻其维修能力和低热量排放。键盘也不错，适合更长的打字会议，别忘了两个操作系统，其中包括恢复DVD光盘。批评明亮，但对比度非常低的显示。
Vostro成就2520为用户提供了三个笔记本电脑的电池寿命最长。此外，您还可以订购它没有操作系统。 TRAVELMATE P253-M建议这些用户看重的运作噪音低。总体而言，所有这三款笔记本做他们的目的到底是什么做的。虽然它们非常类似的装备，每一个擅长在一个不同的区域。
