外壳和连接性--ThinkPad的坚固外壳
联想为ThinkPad L15使用了坚固的塑料结构,这应该是为了保护笔记本电脑不受颠簸和溅水的影响。做工质量很高,我们没能发现任何缺陷。盖子也很稳定,抗扭转,可以向后折叠达180度。铰链在任何时候都能将显示屏牢牢固定在位置上。
在连接方面,制造商从ThinkPad L15 Gen 1 ,提供了与前代产品相同的基本配置,有一个对接端口和一个USB-C充电端口。不过,如果你需要使用Thunderbolt 4,你必须选择英特尔的型号。
内置WWAN的NanoSIM插槽位于microSD读卡器上方。用于这一目的的相应天线已经安装在笔记本电脑内,这就是为什么你只需要将LTE模块插入空闲的插槽。第二个RAM插槽,在我们的测试配置中是空闲的,提供了进一步的维护选项。SSD和WLAN模块也可以被替换。
通过我们的AV Pro V60参考存储卡,存储卡读卡器本身实现了良好的读写速度,与我们的测试领域相当。尽管支持Wi-Fi 6和蓝牙5.1的无线连接,但采用AMD处理器的ThinkPad L15只实现了平均速度,与我们的Netgear Nighthawk AX12参考路由器的测试领域相比处于低端。
网络摄像头只提供了广泛传播但仍然很低的0.9MP分辨率,我们的测试图像显示了相应的适度的图片质量。它还与Windows Hello兼容,可以用机械快门关闭。

输入设备 - 带背光的笔记本电脑键盘
L15 Gen 2还配备了熟悉的ThinkPad布局与数字键盘。因此,按键的布局和提供的反馈使其能够轻松地输入较长的文字。特殊键也采用了单键布局,因此只有F键有双重任务。两级键盘背光也可以通过空格键+Fn组合激活,它可以相对均匀地照亮字符。
ClickPad和带有分离式鼠标按钮的TrackPoint都可以作为鼠标的替代品。两者都非常适合精确控制鼠标指针,并对输入作出可靠的反应。此外,ThinkPad L15第二代还提供了一个指纹传感器和一个可选的智能卡读卡器作为商务功能。
显示屏 - 具有良好的校准,无闪烁现象
ThinkPad L15 G2的屏幕由一个15.6英寸的IPS面板组成,提供1920x1080像素的分辨率。平均276cd/m²的最大亮度在我们的测试领域中处于领先地位。另一方面,其86%的分布是平均的。联想避免使用PWM进行
亮度控制,这意味着眼睛敏感的用户不应该期待任何困难。除了这里使用的显示配置,联想还列出了L15 Gen 2配备1366x768像素的TN面板,以及配备1920x1080像素的可触摸IPS面板。

我们的测量结果显示,ThinkPad L15具有相对较好的1,146:1的对比度和仅略微升高的0.26 cd/m²的黑度。这使它在我们选择的对比设备中处于中间位置。色域覆盖率稍好一些,与华硕VivoBook S15 D533UA
。此外,CalMAN分析显示,颜色的再现与开箱时的偏差非常小。然而,通过校准,DeltaE 2000的值仍然可以从1.7提高到0.5。相应的ICC文件可以在位于顶部、显示器亮度分布图右侧的窗口中下载。
显示器的亮度足以在户外以及有阴凉的日子里清晰地显示图像内容。然而,在阳光直射下,显示屏的亮度就不够了。内置的IPS面板在可视角度上也非常稳定,即使从非常平坦的角度看,它显示的内容也没有失真或不准确的颜色。
性能 - 恒定的CPU性能
联想ThinkPad L15是一款相对实惠的商务笔记本电脑,它适用于各种办公应用。虽然我们的测试配置为中等要求提供了足够的性能,但也可以通过额外的费用获得更强的CPU和修改的内存配置。
处理器
这里安装的AMD Ryzen 5 5600U是一个六核处理器,可以同时处理多达12个任务。其时钟频率在2.3和4.2GHz之间,但实际性能还取决于冷却系统和TDP配置。后者可以由制造商在10至25瓦之间定义,联想选择了10瓦的下限。
在我们的Cinebench R15耐力测试中,ThinkPad L15 Gen 2因此可以在很长一段时间内将其性能保持在一个恒定的水平。实现的速率比Lenovo ThinkPad L15 laptop review - Decent office companion with high system performance ThinkPad L15 Gen 1 中的AMD Ryzen 7 PRO 4750U Processor - Benchmarks and SpecsAMD Ryzen 7 Pro 4750U低了约9%。如果需要更多的性能,ThinkPad L15 Gen 2也可以使用AMD Ryzen 7 Pro 5850U ,需要额外支付80欧元(约94美元)。
Cinebench R15 Multi endurance test
在个别学科中,Ryzen 5 5600U可以在我们的测试领域中名列前茅,特别是因为其良好的单核性能。相比之下,像华硕VivoBook S15或ThinkPad L15 Gen 1与Ryzen 7 Pro 4750U这样的设备在多核性能方面表现得略好。

ThinkPad L15第二代的AMD Radeon RX Vega 7集成显卡
单元适用于对图形性能要求不高的应用。在3DMark基准测试中,性能略高于我们测试领域中大多数其他设备的水平。因此,简单的图像编辑任务也是可能的,但对于要求高的3D应用来说,性能不够。然而,AMD RX Vega 7得益于使用双通道配置的内存,这就是为什么通过安装第二个内存模块仍然可以实现改进。其他显卡提供的性能比较,可以在我们的 GPU基准测试文章中找到 。

温度
ThinkPad L15的表面在负载下的温度高达44.1°C(~111°F)。最热的地方是底部的左后角,使掌托的温度始终保持适度。
在我们大约一小时的压力测试中,ThinkPad L15 Gen 2内部的温度上升到71.3 °C(约160 °F)。在这个过程中,时钟速率下降到1.9GHz,低于基本时钟。在测试接近尾声时,系统也出现了严重的卡顿,但在消除高负荷后,它又迅速稳定下来。在日常使用中,这意味着由于温度过高而造成的限制只有在长时间运行高要求的应用程序时才会出现。
(±) The maximum temperature on the upper side is 42.8 °C / 109 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 46 °C / 115 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25.5 °C / 78 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 27.3 °C / 81.1 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 (+0.4 °C / 0.8 F).
发言人
联想ThinkPad L15第二代的扬声器不会变得特别响亮,但它们提供了相当广泛的声谱。这使得它们完全适合在非常安静的环境中播放媒体内容,但从长远来看,建议使用外部扬声器或耳机。

结论 - 稳定的笔记本电脑提供良好的办公性能
联想ThinkPad L15 Gen 2提供的正是它所宣传的功能。它的性能足以满足各种办公应用的需要,而且还能为简单的图像编辑任务提供动力,比如说。系统在重载时可能会有点慢,但这在日常使用中应该是个例外。
凭借其坚固的外壳和良好的输入设备,联想ThinkPad L15 Gen 2总体上给人留下了良好的印象。
然而,由于使用了AMD的CPU,你不得不不使用Thunderbolt 4,而且Wi-Fi速度在许多竞争对手中更高。虽然不到8小时的电池寿命足以在没有电源插座的情况下度过一个工作日,但其他机型,如华硕VivoBook S15或 戴尔Latitude 15 5511,在这里也能提供更好的速率。
价格和可用性
在撰写本文时,似乎只有英特尔版本的联想ThinkPad L15 Gen 2可用。你可以在制造商的网上商店找到它。有广泛的定制选项,价格约为780美元起。另外,你也可以等待该设备在其他网站上市,如Amazon,newegg, 或联想自己的网站,例如。
