机箱和连接性 - 带有Thunderbolt 4的廉价ThinkPad
联想ThinkPad L14 G2的外壳是由坚固的塑料制成。制造质量处于高水平。任何地方都没有缝隙或缺口。显示器的开启角度为180度。显示屏的盖子相当坚硬。
与其他现代笔记本电脑相比，显示屏的边框看起来有点厚。ThinkPad L14 G2的重量约为1.7公斤，比我们为这次审查选择的所有其他竞争设备的重量都大。联想的笔记本电脑也比其他商务笔记本电脑更深、更厚一些。
两个USB-C端口中的一个可用于充电。另一个USB-C端口支持Thunderbolt 4，还集成了联想的对接端口。可选的是，L14 G2有一个智能卡读卡器和LTE，为此有相应的卡槽。
联想笔记本电脑中的microSD读卡器使用我们的参考级存储卡AV Pro V60，实现了73.91MB/s（写）和84.92MB/s（读）的体面数据传输率。
在用我们的参考级路由器Netgear Nighthawk AX12进行的Wi-Fi测试中，联想ThinkPad L14 G2在传输数据时只达到了907 MBit/s的平庸速度，在接收数据时则为662 MBit/s。
L14 G2的网络摄像头和目前大多数笔记本一样，只提供0.9MP的分辨率。因此，图像质量很差。一切看起来都很模糊，即使在良好的照明条件下，颜色也不清晰。

输入设备 - 带有背光键盘的联想笔记本电脑
ThinkPad L14 G2的键盘提供了一个清晰的启动点，适合长时间打字使用。键盘的布局是经过深思熟虑的。在这里，即使是方向键也不承担双重任务。两级背光允许用户在弱光环境下工作，并能均匀地照亮按键，没有任何眩光。
一个塑料ClickPad和一个TrackPoint作为鼠标的替代品。这两种输入设备都很适合导航鼠标指针。点击可以通过机械和触摸方式可靠地触发。在我们审查期间，联想笔记本的指纹传感器也能可靠地识别存储的指纹。
显示屏 - ThinkPad L14 G2的对比度良好
联想ThinkPad L14 G2有一个14英寸IPS屏幕，原始分辨率为1920x1080像素。由于最大亮度为294cd/m²，联想笔记本电脑在我们的对比表中占据了一个位置。90%的亮度分布是非常好的。
此外，没有 PWM闪烁，这意味着眼睛敏感的人不必担心任何问题。

性能 - Tiger-Lake的CPU在负载下不会出现节流现象。
根据规格表，ThinkPad L14 G2配备了不同的CPU，其中有 英特尔酷睿i7-1165G7是顶级选项。内存配置也不尽相同，而且没有配备专用GPU的型号--至少在欧洲是这样。在其他地方，L14 G2可以使用 GeForce MX450.我们的评测模型配备了一个 英特尔酷睿i5-1135G7，8GB内存和256GB固态硬盘，因此很适合各种办公应用。
处理器
该 英特尔酷睿i5-1135G7是一个4核/8线程的CPU。时钟频率在2.4和4.2GHz之间，据此，最大性能取决于冷却系统以及TDP。在这里，联想配置的短期值为60W（PLA2），长期值为28W（PL1）。
在我们的Cinebench R15压力测试中，ThinkPad L14 G2成功地将其性能保持在一个较高的水平。
Cinebench R15 Multi Stress Test
在某些基准测试中，联想的笔记本电脑实现了高水平的多核性能，只有拥有AMD Ryzen 7 5850 Pro的竞争对手能够击败它。单核性能足以在我们的比较图表中占据一个位置。Geekbench的低分是引人注目的，即使在第二次基准测试运行后也没有明显改善。
在电池电量方面，启用电池效率模式时，Cinebench R15的多核得分下降到248分。在性能模式下，即使拔掉插头也能达到872分。

图形卡
这款 Intel Iris Xe Graphics G7 80EUs负责图像渲染。iGPU受益于在双通道模式下运行的快速RAM，而这里的情况并非如此。
由于在我们的评测设备中，RAM以单通道模式运行，因此在3DMark基准测试中的性能低于其他配备该GPU的笔记本。通过安装第二个RAM模块可以提高性能。
在电池供电的情况下，3DMark 11的得分在性能模式下为3787分，在效率模式下为2494分。 你可以了解iGPU与其他图形卡的比较，在我们的 GPU基准测试页面上了解iGPU与其他显卡的比较。

系统噪音
在日常使用中，当使用办公应用程序和浏览互联网时，ThinkPad L14 G2的风扇是听不到的，这导致了安静的操作。即使在我们的压力测试中，主动冷却系统也只是在很晚的时候才启动，在风扇稳定旋转的情况下，最大声压级为41.1 dB(A)。

温度
根据我们的测量，ThinkPad L14 G2的表面温度在非常大的负荷下达到51.3°C（124.34°F）。最热的地方在右上角；腕部休息区总是感觉相对凉爽。
在我们的长期压力测试中，L14 G2内部的温度很快就达到了100℃（212°F）。冷却系统最终能够将其降低到93℃（199.4℉）。时钟频率在短时间内明显低于基本频率，但随后稳定在3.8GHz左右。尽管负载很重，系统仍然可以使用。由于冷却解决方案工作良好，而且在我们的压力测试方案中看到的负载在实践中极不可能发生，我们预计在日常使用中不会看到任何热节流。
(+) The maximum temperature on the upper side is 36.6 °C / 98 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 51.3 °C / 124 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 21.7 °C / 71 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.6 °C / 83.5 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-0.9 °C / -1.6 F).
发言人
联想笔记本电脑的扬声器很安静，听起来很尖锐。因此，在非常安静的环境中偶尔播放媒体内容是可能的。不过，我们建议使用耳机或外部扬声器。

能源消耗
闲置时，我们测得的耗电量为7W。在压力测试中，能耗峰值为59W。因此，耗电量与其他具有这种硬件的笔记本相当。
附带的65瓦电源适配器即使在负载情况下，为联想笔记本电脑提供足够的电力应该没有问题。

结论 - 好的笔记本，有一些改进的空间
联想的ThinkPad过去和现在都是不错的办公笔记本电脑。L系列是如此，因此ThinkPad L14 G2也是如此。性能处于良好水平，系统和应用程序都感觉反应灵敏。升级内存的选项弥补了相对较低的图形性能。
联想ThinkPad L14 G2是一个很好的日常伴侣，即使使用的是英特尔CPU，但更长的电池运行时间也是非常值得赞赏的。
然而，在一些领域，竞争对手正在变得更好。最重要的是，这里必须提到重量和尺寸。在直接比较中，L14 G2看起来比其他14英寸笔记本更大更重。显示屏和电池寿命在未来肯定能得到改善。
总而言之，ThinkPad L14 G2是值得购买的。与竞争对手如 申克威盛14，以及 华硕ExpertBook B1 B1400或 Acer Swift 5 SF514不过，也有很好的替代品可以选择。
价格和可用性
采用英特尔CPU的联想ThinkPad L14 G2目前在亚马逊上销售。.
