联想 B570e-N2F23GE 笔记本测评
According to Lenovo, the models of the B-series are "budget-friendly notebooks for home and home office". The features and the price range certainly support this statement. Our test sample comes equipped with an Intel Pentium B960 dual-core CPU, an Intel HD Graphics (Sandy Bridge) GPU, and 4GB of system RAM. The hard drive has a capacity of 320GB. Even a DVD-RW drive is on board. We reviewed another member of the series – the Lenovo B570-M58G4GE (Intel Core i3-2330M, Intel HD Graphics 3000) - not too long ago.
For our evaluation, we compare this notebook to two competitors: the Sony Vaio VPC-EH3C0E/W (Intel Pentium B960, Intel HD Graphics (Sandy Bridge)) and Lenovo’s own G585 (AMD E2-1800, AMD Radeon HD 7340).
据联想的B系列，该机型是“预算友好的家庭和家庭办公室的笔记本电脑”。功能和价格范围，当然支持这种说法。我们的测试样机配备了英特尔奔腾B960双核CPU，Sandy Bridge的英特尔HD图形（）GPU，和4GB的系统内存。硬盘驱动器的容量为320GB。即使是DVD-RW驱动器在主板上。我们审查了该系列的另一名成员 - 联想B570-M58G4GE的（英特尔酷睿i3-2330M，英特尔HD Graphics 3000） - 不是很久以前。
对于我们的评价，我们比较这两个竞争对手：笔记本索尼VAIO VPC-EH3C0E/ W（英特尔奔腾B960，英特尔高清显卡的Sandy Bridge）和联想自己的G585（AMD E2-1800，
Case
The first look leaves no doubt: this notebook is designed to be a tool. The chassis is very similar to the one Lenovo uses for the B570-M58G4GE, but the surfaces are textured differently. The B570e-N2F23GE is entirely made from matte, black plastic. Only the display is glossy. Since the surface isn't smooth, it's not very susceptible to fingerprints. The quality of the construction and overall sturdiness is quite acceptable. For more information on the chassis, please take a look at the review of the Lenovo B570-M58G4GE.
先来看看毫无疑问，这款笔记本的设计是一个工具。底盘是非常相似到一个联想为B570-M58G4GE的使用，但不同的表面纹理。 B570e-N2F23GE完全是由磨砂，黑色塑料。仅显示有光泽。由于表面是不光滑的，这不是很容易受到指纹。建设，整体坚固的质量是完全可以接受的。机箱上的更多信息，请看一看的联想B570-M58G4GE的审查。
Connectivity
The number of the ports and their location is identical to the Lenovo B570-M58G4GE, although the Lenovo B570e-N2F23GE lacks the USB 2.0/eSATA combination port. In addition, the fingerprint reader is also missing. Otherwise all ports one might need are included, even though USB 3.0 is not offered on any notebook in the Lenovo B570 and B570e series.
这些端口的数量和它们的位置是相同到联想B570-M58G4GE的，虽然联想B570e-N2F23GE的缺乏USB2.0/eSATA组合端口。此外，指纹识别器也不翼而飞。否则可能需要的所有端口，一个USB 3.0，即使不提供任何在联想B570和B570e系列笔记本。
Communication
Our test system features a (not identified) WLAN module from Broadcom. The module supports the usual standards 802.11 b/g/n. For wired connections via RJ45, Lenovo sources a well-known Gigabit-Ethernet controller from Realtek (RTL8168/8111 family). A Bluetooth module is not part of the package. The display frame houses a webcam.
Accessories
The only additional items in the box are a quick-start guide and pamphlets with security and warranty information.
Operating System
The Lenovo B570e-N2F23GE ships with Windows 7 Home Premium (64 Bit). A Windows 7 DVD is not included. Potential restores rely on the recovery partition.
通讯
我们的测试系统采用了来自Broadcom WLAN模块（未鉴定）。该模块支持802.11 B / G/ N通常的标准。对于有线连接通过RJ45，联想来源的一个著名的千兆以太网控制器从瑞昱（RTL8168/8111家庭）。一个蓝牙模块是不是包的一部分。的显示框设有一个网络摄像头。
饰品
唯一的额外的包装盒中有一个快速启动指南和小册子，安全性和保修信息。
操作系统
联想B570e N2F23GE附带的Windows7家庭高级版（64位）。一个Windows 7 DVD不包括在内。潜在还原，依靠恢复分区。
Lenovo OneKey Recovery
Lenovo OneKey Recovery
System recovery is very easy: with the notebook turned off, the user only needs to press the OneKey Recovery button (the small button next to the power button). The notebook then turns on and starts the Lenovo OneKey Recovery automatically. Once the option "OneKey Recovery" is selected and the image to restore has been selected (either the factory image or one the user has subsequently created), the restore starts. Important to keep in mind: the system will be reset and all data created (and programs installed) after the image date will be erased.
联想一键恢复
系统恢复是很容易的：与笔记本电脑关闭时，用户只需要按下“一键恢复”按钮（电源按钮旁边的小按钮）。然后打开笔记型电脑，并自动启动联想一键恢复。一旦“一键恢复”的选项被选择和恢复的图像已被选择（无论是工厂图像或1随后创建用户），在还原开始。重要的是记住：系统将被复位和创建的所有数据（和安装的程序）后的图像的日期将被删除。
Software
Lenovo is pretty generous with the included software. We found the following programs pre-installed: Adobe Reader X, Google Chrome, Cyberlink PowerDVD 10, Cyberlink Power2Go (DVD-/CD burner software), Cyberlink Youcam (webcam software), McAfee Antivirus Plus, Microsoft Office 2010 Starter, and Windows Live Essentials 2011. In addition, Lenovo supplies some specific tools. One example is the Lenovo EE Boot Optimizer, which optimizes and accelerates the system boot and startup process. Port Locker might be more interesting for the business user: it can prevent unauthorized data copy to or from USB attached devices or media cards, unless the user supplies a password.
Maintenance
The underside of the notebook is home to a fairly large maintenance cover. Hard drive, RAM, BIOS battery, and WLAN module are all accessible (but the system cooling fan is not). Unlike the B570-M58G4GE, the B570e only comes with one RAM slot (which is home to a 4GB module). Maximum RAM is 8GBbut requires removal of the already installed module.
It's pretty easy to swap out the hard drive. One screw needs to be removed - then the hard drive caddy can be taken out. After the old drive has been swapped out for the new one, the caddy gets re-inserted. One caveat: Lenovo uses a drive that is 7 millimeter thick - and not the 2.5-inch typical standard of 9.5 millimeter.
Warranty
Lenovo offers a 12 month depot warranty. In case of a defect, the customer needs to send the notebook directly to the manufacturer. Lenovo offers an extension of the warranty to 24 or 36 months for 30 or 80 Euros, respectively. A tip: the Lenovo Online Shop allows the user to enter the serial number of the notebook to find out what warranty options they have available. An extended warranty can then also be purchased directly from a dealer, not just online.
软件
联想是非常慷慨的软件。我们发现了以下预安装的程序：使用Adobe Reader X，谷歌Chrome浏览器，讯连科技PowerDVD10，讯连科技“威力酷烧”（DVD-/CD刻录软件），讯连科技YouCam网络摄像头软件，McAfee防病毒+，微软Office 2010入门，和Windows Live Essentials 2011的。此外，联想提供了一些特定的工具。其中一个例子是联想EE引导优化器，优化和加速系统的启动和启动过程。港储物柜，为商业用户可能会更有趣：它可以防止未经授权的数据复制到USB连接的设备或媒体卡，除非用户提供一个密码。
保养
笔记本电脑的底部是一个相当大的维修盖。硬盘驱动器，内存，BIOS电池，WLAN模块都可以（但系统冷却风扇是不是）。与B570-M58G4GE，B570e只配备了一个内存插槽（这是到4GB模块）。最大RAM是8GBbut的要求拆除已经安装的模块。
这是很容易交换的硬盘驱动器。需要被删除的一个螺丝， - 然后在硬盘驱动器的球童可以取出。被换出的新的旧的驱动器后，球童被重新插入。有一点需要注意：联想采用7毫米厚的 - 而不是典型的标准的9.5毫米2.5英寸驱动器。
保
联想提供车厂保修期为12个月。在有缺陷的情况下，客户的需求直接向制造商发送的笔记本电脑。联想提供了一个扩展的保修期分别为30或80欧元，24个月或36个月。小提示：在联想在线商店允许用户输入序列号的笔记本电脑，以找出他们有那么大的保修选项。延长保修期，然后也可以直接购买从经销商，不只是在网上。
Input Devices
Keyboard
The keyboard of the Lenovo B570e-N2F23GE is the same one found on the Lenovo B570-M58G4GE. Keystrokes are quite precise and the keyboard is well suited for those who need to type a lot.
Touchpad
The 10 x 5 centimeter (3.94 x 1.97 inches) touchpad is also identical to the one used in the Lenovo B570-M58G4GE. The surface is slightly rough but fingers glide easily. Since the touchpad is multi-touch enabled, functions like zooming with two fingers and other gestures are supported. The two mouse buttons underneath the touchpad feature clear tactile feedback.
键盘
该键盘的联想B570e-N2F23GE的是相同的上联想B570-M58G4GE的人发现。按键是相当精确的，非常适合那些需要输入大量的键盘。
触摸板
10×5厘米（3.94×1.97英寸）触控板在联想B570-M58G4GE的使用也是相同的。表面略显粗糙，但手指滑过容易。触摸板是多点触摸功能，支持用两个手指等手势缩放等功能。两个鼠标按键下方的触摸板配有清晰的触觉反馈。
Display
Our test system features a 15.6-inch display with a native resolution of 1366x768 pixels. The panel is LED backlit and is a glare-type. Unfortunately, there are no other display options for the Lenovo B570e - too bad, since a matte display would certainly look better on a business-type notebook. The average brightness of 182 cd/m² is average at best, although the Sony Vaio VPC-EH3C0E/W is only marginally better (199.6 cd/m²). The Lenovo G585, on the other hand, has an average brightness of 236 cd/m² and clearly outclasses both the Sony and the B570e.
我们的测试系统采用了15.6英寸的显示屏，与原生分辨率为1366×768像素。 LED背光面板和炫光类型。不幸的是，有没有其他的显示选项，联想B570e - 太糟糕了，因为雾面显示屏肯定会更好看商务型笔记本电脑。平均亮度为182 cd /m²的平均水平是最好的，虽然索尼VAIO VPC-EH3C0E/ W仅略好（199.6 cd /m²的）。另一方面，联想G585，平均亮度为236 cd /m²的，清楚地就超越了索尼和B570e的。

58% Display P3 (Argyll 2.2.0 3D)
We measured a black point value of 0.9 cd/m² - again just about average. Given the fact that this notebook resides in the bottom price bracket, the black point is actually quite decent. The contrast is 202:1 and is not particularly great. However, both the Sony Vaio VPC-EH3C0E/W (1.54 cd/m², 144:1) and the Lenovo G585 (1.61 cd/m², 145:1) fare worse in this test. The B570e is not able to accurately reproduce the sRGB and AdobeRGB color spaces. This is not really an issue here, as the system is not going to be used by photographers and graphics professionals. We have to say that the display gets pretty close to the sRGB color space - again something we don't see often in this price range.
我们测量了一个黑点为0.9 cd /m²的 - 只是平均水平。鉴于这一事实，这款笔记本驻留在底部的价位上，黑点其实是相当不错。对比度是202:1，是不是特别大。然而，索尼的Vaio VPC-EH3C0E/ W（1.54坎德拉/平方米，144:1）和联想G585（1.61坎德拉/平方米，145:1）票价在这个测试中差。的的B570e不能够准确地重现sRGB和AdobeRGB色彩空间。这是不是一个真正的问题在这里，因为系统是不会被使用的摄影师和图形专业人士。我们不得不说，显示器有相当密切的sRGB色彩空间 - 什么东西我们不经常看到在这个价格范围内。
The low brightness of the display as well as the fact that it is highly reflective makes outdoor use almost impossible. The user needs to make sure he or she is in the shade and avoids direct sunlight at all costs.
低亮度的显示，以及是高反射的事实，即它使得室外使用几乎是不可能的。用户需要确保他或她是在阴凉处，避免阳光直射的地方不惜一切代价。
As far as viewing angle stability is concerned, the Lenovo B570e-N2F23GE behaves exactly as one would expect from a low-priced laptop. Even small changes in the vertical lead to a washed out picture and color inversions, while the horizontal plane is less susceptible to changes in viewing angles.

Performance
The Lenovo B570e-N2F23GE is a laptop designed for the home and home office user. As such, it's supposed to handle a daily workload of surfing, internet communication, office tasks, and DVD playback. HD videos are no problem for the B570e. When we played a video in FullHD (1920x1080 pixels) and H.264 encoding, we didn't encounter any issues. The processor workload was at around 33% (we used DXVA Checker) and the video played without any lags. YouTube videos in the same format also play flawlessly. Since the notebook also features HDMI out, it can be used as a movie player in the living room, as it is capable of playing all common formats and does so quietly.
The Intel GPU takes some load off the processor during playback - Intel calls this functionality "ClearVideo". Without this optimization, the CPU would have to bear the brunt of the workload and subsequently the utilization would be higher. The default program for playing videos, PowerDVD 10, is able to take advantage of the technology, although our test sample had it deactivated (it might be a default setting). Activating the hardware acceleration is simple: open "Settings", select the sub-menu "Video", and place a check mark in the box for hardware acceleration.
联想B570e-N2F23GE是为家庭和家庭办公用户设计的一台笔记本电脑。因此，它应该处理每天的工作量冲浪，网络通信，办公任务和DVD播放。高清视频是没有问题的B570e。当我们发挥的FullHD（1920×1080像素）和H.264编码的视频中，我们没有遇到任何问题。处理器的工作量在33％左右，（我们使用DXVA检查）和视频播放没有任何滞后。 YouTube视频相同的格式也发挥堪称完美。由于笔记本还采用了HDMI输出，可以在客厅作为一个电影播放器，因为它是能够播放所有常见格式，就这样静静的。
英特尔的图形处理器（GPU）在播放过程中，需要一定的负载关闭处理器 - 英特尔称之为“ClearVideo”这个功能。如果没有这个优化，CPU必须首当其冲的工作量，和随后的利用率会更高。默认程序，用于播放视频时，PowerDVD10，是能够利用的技术，虽然我们的测试样机已停用（这可能是一个默认设置）。激活的硬件加速很简单：打开“设置”，选择子菜单中的“视频”，硬件加速的包装盒中放置一个复选标记。
Processor
Our test unit comes equipped with an Intel Pentium B960 processor. This dual-core CPU is a member of the Sandy Bridge generation. Core frequency is 2.2 GHz. A Turbo mode is not offered. During our stress test (Prime95 and Furmark in parallel), the CPU frequency remained stable - throttling was not observed. The GPU frequency, however, fluctuated between 650 and 1100 MHz.
Since CPU throttling does not occur, our Cinebench test showed results comparable to other systems equipped with the Intel Pentium B960, like the Sony Vaio VPC-EH3C0E/W. The Lenovo G585 (AMD E2-1800, AMD Radeon HD 7340) is not able to keep up with the other notebooks - not really surprising since it's based on netbook technology. On the other hand, the B570e-N2F23GE is outperformed by the more powerful Lenovo B570-M58G4GE (Intel Core i3-2330M, Intel HD Graphics 3000).
我们的测试样机配备了英特尔奔腾B960处理器。这款双核CPU的Sandy Bridge世代的一员。核心频率为2.2 GHz。不提供的Turbo模式。在我们的压力测试（Prime95和FURMARK平行），CPU频率保持稳定 - 节流，没有观察到。 GPU的频率，但是，在650和1100兆赫之间波动。
由于CPU的限制不会发生，我们CINEBENCH的测试结果相比，其他系统配备了英特尔奔腾B960，像索尼VAIO VPC-EH3C0E/ W。联想G585（AMD E2-1800，AMD的Radeon HD7340）是无法跟上其他笔记本电脑 - 并不令人惊讶，因为它是基于上网本的技术。另一方面，B570e-N2F23GE的是更强大的联想B570-M58G4GE（英特尔酷睿i3-2330M，英特尔HD Graphics 3000）跑赢大市。

System Performance
The components of the Lenovo B570e-N2F23GE make it clear that this is not a high performance system. The system would definitely benefit from a Solid State Disk. In the PC Mark Vantage Test, our test system scored similar to other notebooks with an entry-level CPU - examples are the Toshiba Satellite L755D-14U (AMD A6-3420M, AMD Radeon HD 6520G + HD 7450M Dual Graphics) or the Sony Vaio VPC-EH3C0E/W (Intel Pentium B960, Intel HD Graphics (Sandy Bridge)).
联想B570e-N2F23GE的组件要清楚，这不是一个高性能的系统。从固态磁盘的系统肯定会受益。在PC Mark Vantage的测试中，我们的测试系统获得类似的其他笔记本电脑的入门级CPU - 的例子是，东芝Satellite L755D-14U（AMD A6-3420M的AMD Radeon HD 6520G+ HD7450M双显卡）或索尼的Vaio VPC-EH3C0E/ W（英特尔奔腾B960，英特尔高清显卡的Sandy Bridge）。

Storage Devices
For the B570e-N2F23GE, Lenovo uses a standard (platter-based) hard drive sourced from Western Digital. The hard drive (model Scorpio Blue) has a capacity of 320GB and spins at 5400 RPM. Average transfer rate is 64.5 MB/s - a bit below average for this type of hard drive. The access time of 21.1 ms is also too high.
对于的B570e N2F23GE，联想采用了标准的（单碟）来源西部数据（Western Digital）硬盘驱动器。在5400 RPM硬盘驱动器（型号天蝎蓝）的容量为320GB和旋转。平均传输速率为64.5 MB/ s的 - 这种类型的硬盘驱动器位低于平均水平。 21.1毫秒的存取时间也太高了。
Graphics Card
Intel not only supplies the CPU, but also the GPU for the Lenovo B570e-N2F23GE. The integrated Intel HD Graphics (Sandy Bridge) supports DirectX 10.1 and is based on the Intel HD Graphics 2000. This is definitely a very entry-level GPU that offers limited functionality. Quick Sync (Intel's encoding and decoding technology), for example, has been eliminated.
The results of the different 3D Mark tests are comparable to other notebooks with the Intel Pentium B960 CPU and Intel HD Graphics (Sandy Bridge) GPU. Examples are Lenovo's own IdeaPad G580-MBBG3GE and the Sony Vaio VPC-EH3C0E/W. Even the Lenovo G585 (AMD E2-1800, AMD Radeon HD 7340) can keep up with the other systems. Since the G585 supports DirectX 11, it can actually win one test (in 3D Mark 2011) that the Lenovo B570e can't complete (since it only supports DirectX 10.1). None of the four systems comes close to the results of the Lenovo B570-M58G4GE (Intel Core i3-2330M, Intel HD Graphics 3000).
英特尔不仅提供CPU，但也是GPU的联想B570e N2F23GE。集成Intel HD Graphics（距桥），支持DirectX 10.1和基于英特尔HD Graphics2000。这绝对是一个非常入门级GPU，提供有限的功能。快速同步（英特尔的编码和解码技术），例如，已经被淘汰。
不同的3D标记的测试结果与其他笔记本电脑采用英特尔奔腾B960 CPU和Intel HD Graphics的Sandy Bridge GPU。例子是联想自己的IdeaPad G580-MBBG3GE和索尼VAIO VPC-EH3C0E/ W。即使是联想G585（AMD E2-1800，AMD的Radeon HD7340）能保持与其他系统。由于G585支持DirectX 11，它实际上可以赢得一个测试（在3D MARK2011），联想B570e无法完成（因为它仅支持DirectX10.1）。四个系统接近联想B570-M58G4GE（英特尔酷睿i3-2330M，英特尔HD Graphics 3000）的结果。

Gaming Performance
Those trying to find a gaming rig need to look elsewhere. The Lenovo B570e-N2F23GE is not suitable for demanding 3D games, as the frame rates are just too low. Some games will work with the details and the resolution set to the lowest settings. The (not very demanding) game FIFA 12, for example, works reasonably well.
那些试图找到一个游戏平台，需要到别处寻找。联想B570e-N2F23GE是不适合要求苛刻的3D游戏，如帧速率太低。有些游戏会工作的细节和分辨率设置为最低的设置。 （要求不是很严格）游戏FIFA 12，例如，合理地发挥作用。

Emissions
A notebook that's designed for work is supposed to produce as little noise as possible. The Lenovo B570e-N2F23GE certainly fulfills this requirement. During idle, we measured 30.3 dB - pretty much inaudible. One has to listen very closely to hear the hard drive, as it is very quiet. Even under full load (Prime95 and Furmark in parallel), we only measured 36.9 dB - still very acceptable.
为工作而设计的笔记本电脑，应该尽可能产生较小的噪音。当然联想B570e-N2F23GE的满足这一要求。在空闲期间，我们测量了30.3分贝 - 几乎是听不见的。听着很密切听到硬盘驱动器，因为它是非常安静的。即使在满载情况下（Prime95和FURMARK平行），我们只测量36.9分贝 - 还是很可以接受的。

Temperature
The Lenovo B570e-N2F23GE doesn't run very hot. During idle, temperatures remained completely reasonable. We measured between 27 and 36 °C(80.6 and 96.8 °F) on both the top and the bottom. Working with the notebook on the lap is certainly possible. Under maximum load (Prime 95 and Furmark at the same time), the temperatures only increased slightly to between 28 and 40 °C(82.4 and 104 °FAt the palm rest, we measured about 30 °C(86 °F).
During the stress test (we ran Prime 95 and Furmark in parallel for at least one hour) we always had the maximum CPU performance available - no matter if the laptop was plugged in or running on battery. The frequency of the GPU fluctuated between 850 and 1100 MHz (with the power adapter plugged in) and between 650 and 1100 MHz (battery). The temperature leveled out at 67 to 68 °C (152.6 to 154.4 °F).
不运行非常联想B570e-N2F23GE的热。在空闲时，气温仍然是完全合理的。我们测量了27和36°C（80.6和96.8°F）之间的顶部和底部。工作与笔记本电脑放在膝上是有可能的。在最大负载下（总理95和FURMARK在同一时间），温度只有轻微上升至28至40°C（82.4至104°脂肪的掌托，我们测量了大约30°C（86°F）。
在压力测试（我们跑了总理95和Furmark的平行至少一个小时），我们总是有最大的CPU性能 - 无论如果笔记本电脑在充电或电池上运行。的GPU的频率在850和1100兆赫（与电源适配器插上）之间和在650和1100兆赫（电池）之间波动。温度趋于平稳，在67至68°C（152.6至154.4°F）。
(+) The maximum temperature on the upper side is 37.2 °C / 99 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(±) The bottom heats up to a maximum of 40 °C / 104 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 30.5 °C / 87 F, compared to the device average of 29.5 °C / 85 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 27.6 °C / 81.7 F (-6.2 °C / -11.1 F).
Speakers
The stereo speakers of the Lenovo B570e are located above the keyboard and sound pretty decent, although bass is lacking. For a business laptop, the speakers are good enough. Those wanting better sound quality can always connect external speakers or headphones.
Power Consumption
As far as power goes, the Lenovo B570e-N2F23GE is pretty frugal. During idle, we measured a power consumption of 8.3 to 11.7 watts. The values for the Sony Vaio VPC-EH3C0E/W are almost identical. Under maximum load (Prime 95 and Furmark), the B570e consumed 41.8 watts and remained quite a bit under the Sony (49.3 watts). Under medium load (we ran the 3D Mark 06 benchmark test), the Lenovo consumed 31.9 watts, the Sony 37.5 watts. Both notebooks don't come close to the power requirements of the G585 - but we have to take into consideration that the CPU part of the AMD APU is less powerful and power hungry then the CPU part of the Intel Pentium B960.
Interesting is a comparison with the Lenovo IdeaPad G580-MBBG3GE: the system features almost the same components as the B570e-N2F23GE but requires more power. We measured a difference of 10 watts during full load and about 4-5 watts more during idle. We don't know the cause for this difference.
至于电源方面，联想B570e-N2F23GE是很节俭的。在空闲期间，我们测量了8.3到11.7瓦的功率消耗。索尼VAIO VPC-EH3C0E/ W的值几乎是相同的。 B570e消耗根据最大负载（总理95和FURMARK），，41.8瓦特，并保持相当多的索尼（49.3瓦）。在中等负荷（运行在3D Mark06的基准测试），联想消耗31.9瓦特，索尼37.5瓦特的。这两款笔记本不接近的G585的电源要求 - 但我们必须要考虑到的AMD APU的CPU部分是不那么强大和耗电的英特尔奔腾B960的CPU部分。
比较有意思的是，联想IdeaPad G580-MBBG3GE：该系统具有几乎相同的组件B570e-N2F23GE，但需要更多的权力。我们测量了满负荷，并在空闲时约4-5瓦，10瓦差。我们不知道这种差异的原因。
