联想ThinkPad L15 G2评测。600欧元(约680美元)的办公笔记本电脑
就联想的ThinkPad L15 G2而言,我们已经看了一个配备AMD硬件的模型。 配备AMD硬件的型号,我们也已经测试了稍小的14英寸的 联想ThinkPad L14 G2.
现在轮到L15 G2的实惠配置了,它已经可以以大约600欧元(约680美元)的价格出售,配备了 英特尔酷睿i3-1115G4,8GB内存和256GB的SSD。虽然这应该允许它无障碍地运行办公应用程序,但我们不期望有足够的储备来完成更苛刻的任务。

机箱和设备 - 带Thunderbolt 4的ThinkPad L15 G2
联想ThinkPad L15 G2的外壳由坚固的塑料制成,具有高质量的工艺。盖子非常耐翘,可以打开到180°角。在我们的测试装置中,我们没有发现任何做工上的问题。
由于边框与其他笔记本电脑相比略大,ThinkPad L15 G2的尺寸也略大。1.9公斤(约4.2磅)的重量也相对较高,但L15 G2仍然适合随身携带。
除了可选的LTE和智能卡读卡器外,联想ThinkPad还提供了一个集成到对接端口的雷电4端口。这使你可以在已有的连接方式上增加多种连接方式。
使用我们的AV 60 Pro参考存储卡,L15 G2的microSD读卡器在复制时达到了66.99MB/s的良好速度,在读取数据时达到了86.38MB/s,这使它在我们的测试领域处于领先地位。
另一方面,在使用我们的Netgear Nighthawk AX12参考路由器进行的WLAN测试中,传输时为687 Mbit/s,接收数据时为634 Mbit/s,传输速率相对较低。
网络摄像头的分辨率很低,只有0.9MP,这在目前的笔记本电脑中是很普遍的。图像质量也相应较低,显示模糊的物体边缘和苍白的颜色。

输入设备 - 一个好的联想键盘
联想ThinkPad L15 G2的键盘很适合打长文。压力点很明显,而且布局也没有被恼人的、必须履行双重功能的按键所破坏。此外,还有一个单独的数字块。
作为鼠标的替代品,有一个ClickPad和一个Trackpoint。机器人输入法很适合导航鼠标指针,点击可以通过机械或使用触摸方式可靠地触发。在我们的测试中,指纹识别器对存储的指纹也反应良好。
显示屏 - 15英寸笔记本电脑的全高清
ThinkPad L15 G2的显示屏由一块15.6英寸的IPS面板组成,分辨率为1920 x 1080像素。279 cd/m²的最大亮度相对较低,但对于在室内使用完全足够。亮度分布是我们测试领域中最低的,为81%。亮度控制并没有使用任何 PWM因此,眼睛敏感的人不需要担心会遇到任何问题。
除了这里使用的显示屏外,根据数据表,还有带触摸屏和300cd/m²亮度的全高清面板或220cd/m²的高清面板可供选择。

我们的测量结果证明,ThinkPad L15 G2具有1213:1的良好对比度,也具有0.23 cd/m²的良好黑值,这足以在我们的测试领域中占据一席之地。在59.8%的sRGB中,色彩空间的覆盖率对于一台经济型笔记本来说也是平均水平,尽管从绝对值来看非常糟糕。
CalMAN的分析也表明,在交付状态下,色彩的再现已经非常平衡。然而,校准仍然可以带来一些改进。你可以在上面的框架中下载相应的ICC文件,在显示器亮度分布图形的右边。
在户外,联想笔记本电脑可以在阴暗的地方轻松使用,但显示亮度不足以在阳光直射下阅读。面板的可视角度非常稳定,即使从非常陡峭的角度也能读到内容,不会失真,也不会出现失真的色彩。
性能 - 负载下稳定的性能
联想将L系列的ThinkPads定位为价格低廉的工作设备,配置可变。虽然我们的测试设备配备的是入门级硬件,但也有配备更强大的处理器或更大存储设备的配置。所有这些都可以让你执行各种办公任务,运行对图形性能要求不高的应用程序。
处理器
的英特尔酷睿i3-1115G4这里使用的是英特尔Tiger Lake 代的双核处理器。它能够同时运行四个任务,并达到3至4.1GHz的时钟速度。除了冷却系统外,配置的TDP也对实际性能负责。联想在这里配置的短期值为25瓦(PL2),长期值为8瓦(PL1)。
在我们的Cinebench R15恒定负荷测试中, i3-1115G4在我们的Cinebench R15恒定负载测试中,L15 G2中的i3-1115G4也能够在较长的时间内持续保持其性能,并且比相同的处理器,例如在 戴尔Inspiron 15 5502.
Cinebench R15 Multi Constant Load Test
联想ThinkPad L15 G2在大多数单独的学科中取得了略高于平均水平的成绩。在我们的测试领域,它经常能够离开 戴尔 Inspiron 15 5502与i3-1115G4但它并没有达到配备i3-1115G4的竞争对手的数值。 英特尔酷睿i5-1135G7.
当使用 "最佳性能 "电源配置文件时,L15 G2在电池运行中也达到了这里显示的性能。另一方面,当你将配置文件调整为 "更好的电池效率 "时,Cinebench R15 Multi得分从494分降至125分。

图形卡
的 英特尔UHD Graphics Xe G4 48EUs集成在处理器中,负责图像内容的显示。它适合于对图形性能要求不高的应用,如简单的图像处理。
在3DMark基准测试中的结果相对较低,只够在我们的测试领域中排在最后。你可以通过使用第二个RAM模块来提高性能,实现双通道运行。
当充电器断开时,ThinkPad能够保持其图形性能,只要你将电源配置文件设置为提供最佳性能。但即使使用 "更高效 "的电源配置文件,3DMark 11的结果也只是从2,972分略微下降到2,520分。

噪声排放
ThinkPad L15 G2在日常运行中非常安静,即使在负载下,风扇也需要很长时间才能打开。然后它们会产生均匀的呼啸声,在我们的压力测试情况下,音量会增加到37.86分贝(A)。然而,由于这样的负载在日常操作中几乎不会发生,因此联想笔记本电脑也很适合在安静的环境中使用。

温度
根据我们的测量,L15 G2的表面温度在负载下最高上升到53.1℃(127.6°F)。由于这种情况的责任也可以在我们的压力测试方案的超常负载中找到,所以在日常操作中,你应该不会遇到任何表面发热的问题。
在我们一小时的恒定负载测试中,ThinkPads内部的温度短暂上升到100℃(212°F)。当时,时钟速率下降到3GHz的基本时钟速度以下,但冷却系统很快就能将其稳定在这一数值上,约2.8GHz的速度可以维持到测试结束。因此,你不应该期待由于温度过高而造成的任何限制,即使是在重负荷下。
(±) The maximum temperature on the upper side is 44.4 °C / 112 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 53.1 °C / 128 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 20.8 °C / 69 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 24 °C / 75.2 F and are therefore cool to the touch.

发言人
ThinkBook L15 G2的扬声器可以产生相对较低的音量,并提供一个宽广的声谱。这使得它们只适合在非常安静的环境中再现媒体内容,建议使用外部扬声器进行长时间聆听。

消耗功率
我们的测量结果证明,联想笔记本电脑在空闲情况下的平均功耗为8瓦,在负载情况下高达60.31瓦。然而,这个最大值只在短时间内达到,然后就稳定在30至40瓦之间。
附带的电源的额定功率为65瓦,所以它提供了足够的功率。

结论 - 一个良好的价格与稳定的性能相结合
由于其价格合理,联想ThinkPad L15 G2显然可以推荐给所有那些正在寻找用于办公任务的强大笔记本电脑,并且可能以后想升级它。外壳和输入设备的质量非常好,而WLAN和存储性能也与竞争对手处于同一水平。
搭载英特尔CPU的联想ThinkPad L15 G2的平价版提供了非常好的性价比。
联想在存储设备方面确实走了一些弯路。尽管8GB的容量在单通道运行时是足够的,但由于CPU和图形单元之间的共享访问,它变成了有点紧张。在这里,良好的维护选项可以带来一些补救措施,因为它们允许插入第二个RAM模块而没有任何复杂的问题。
与竞争对手相比,如 三星Galaxy Book和 戴尔 Inspiron 15 5502竞争对手,特别是电池寿命还有待提高,而且扬声器也没有提供最好的质量。然而,这些只是小抱怨,并不妨碍推荐购买。
价格和可用性
而联想ThinkPad L15 G2配备了一个英特尔酷睿i5-1135G7在联想的上市价格为629美元目前无法购买。Amazon和BestBuy目前的报价为1049美元。
