结论联想 ThinkBook 14 Gen 8 IAL 是学生的不错选择
如果你没有太多钱，只需要一台笔记本电脑来完成工作，无论是在微软 Office 中工作还是在学习时，联想 ThinkBook 14 Gen 8 IAL 当然非常适合这些任务。它拥有良好的输入设备和日常工作所需的所有端口--RJ45 以太网和 SD 读卡器，甚至比一些更昂贵的设备更具灵活性。此外，出色的可升级性意味着这款设备可以走得更远，而且凭借强大的 Arrow Lake H CPU，它的性能也将持续多年。
联想ThinkBook笔记本电脑的不足之处在于屏幕质量和扬声器缺乏低音等细节，但话又说回来--这并不是一款真正用于多媒体任务的笔记本电脑，在这个价位上，必须做出一些牺牲。我们测试的这款机型最大的缺点是电池续航时间低于平均水平，因为电池容量只有 45 瓦。不过，如果选择配备 60 瓦时大电池的机型，就能弥补这一不足。
Pros
+ 强大的 CPU 性能
+ 多种端口选择，包括 RJ45 和 SD 读卡器
+ 高度可升级（2x M.2、2x SO-DIMM、插座式 Wi-Fi）
+ 漂亮的键盘
+ 经济实惠
Cons
- 廉价显示屏，色域覆盖率低
- 电池容量小，电池续航时间低于平均水平
- 扬声器无低音

外壳和连接性：经济实惠的联想 ThinkBook 笔记本电脑提供多种端口
联想 ThinkBook 14 的基本设计在过去几年中没有太大变化。它采用银灰色机身，铝制盖子和塑料底盖。在这个价位上，质量当然是一个值得关注的问题，而 ThinkBook 在很大程度上做到了坚固耐用。底座和屏幕盖几乎没有松动，但铰链有一些晃动。单手打开是不可能的，但至少屏幕可以打开到 180 度。说到材料质量，ThinkBook 给人的感觉显然与同价位的设备不相上下，至少掌托的漆面很光滑，与底盖粗糙的塑料相比，给人的廉价感稍逊一筹。
这款价格实惠的联想笔记本电脑还有一个优点：它为用户提供了很大的灵活性。ThinkBook 14 Gen 8 配备了现代的 Thunderbolt 4 端口，以及时下罕见的全尺寸 SD 卡插槽（卡伸出）和 RJ45 以太网。此外，联想ThinkBook笔记本电脑有两个SO-DIMM插槽用于扩展内存，M.2 2242固态硬盘也没有焊接--M.2 2280固态硬盘也可以安装，而且还有第二个空闲的M.2 2280插槽。Wi-Fi 卡也没有焊接，这使得 ThinkBook 非常容易维修。

输入设备：良好的联想笔记本键盘
联想采用了 1.5 毫米行程键盘，带有微笑形状的按键和两级 LED 背光，还提供自动模式。键盘具有良好的键入体验，布局合理，方向键和 F 键大小适中。这是一款全能型键盘。
触摸板（12 x 7.5 厘米）是典型的机械式潜水板点击板。它具有光滑的塑料表面，在日常使用中表现良好。总的来说，联想 ThinkBook 笔记本电脑的输入设备非常实用。
显示屏典型的廉价办公笔记本电脑屏幕
联想 ThinkBook 14 Gen 8 始终配备 14 英寸 16:10 IPS LCD，分辨率为 WUXGA（1,920 x 1,200），屏幕亮度达到 300 cd/m²，覆盖 45% 的 NTSC 色域。唯一的选择是触摸或非触摸解决方案；我们的评测样品使用的是非触摸显示屏。
屏幕亮度不达标，最高为 276 cd/m²。总的来说，这是一款廉价屏幕，可用于室内办公环境，但也缺乏色域覆盖，因此不适合任何照片编辑或色彩工作。这是一款典型的经济型办公笔记本电脑屏幕，由于屏幕背光较弱，即使是磨砂显示表面也无法在户外环境中发挥真正的作用。

Display Response Times
ℹ
Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.| ↔ Response Time Black to White | ||
|---|---|---|
| 15.8 ms ... rise ↗ and fall ↘ combined | ↗ 8.7 ms rise |  |

| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 35 % of all devices are better. This means that the measured response time is better than the average of all tested devices (20.5 ms). | ||

| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 31 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.1 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.| Screen flickering / PWM not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8327 (minimum: 5 - maximum: 343500) Hz was measured. | |||

存储设备
联想使用的是 Western Digitial 生产的快速 NVMe PCIe 4.0 固态硬盘。它是一个 M.2 2280 插槽内的 M.2 2242 硬盘--还有第二个 M.2 2280 插槽，因此 ThinkBook 的升级能力很强。在我们的基准测试中，出厂的固态硬盘速度也很快，在基准对比中名列前茅。

图形处理器性能
英特尔 ARC 140T 是 Arrow Lake H Ultra 7 CPU 的标准 GPU 解决方案。从技术上讲，它与去年流星湖 H CPU 的英特尔 ARC GPU 几乎完全相同，只是人工智能性能有所提高。因此，ThinkBook 与老款 Meteor Lake 笔记本电脑相比，取得类似的性能也就不足为奇了。这意味着，ThinkBook 当然可以用于一些对图形要求较高的任务，如轻度游戏，不过较新的游戏只能在图形保真度大幅降低的情况下进行。

温度
在负载情况下，ThinkBook 会发热，但考虑到所使用的强大处理器，温度不会很高。在赛博朋克 2077 测试中，我们测得的最高温度为 46 摄氏度或 115 华氏度。这个温度仅限于设备底部的一个热点，掌托等区域几乎没有发热。
在压力测试中，我们没有发现任何节流现象。

联想使用的扬声器声音很大，但缺乏低音效果。这使得 ThinkBook 14 Gen 8 IAL 非常适合在办公室使用，但不太适合听音乐。

能源管理：小电池限制了电池续航时间
耗电量
ThinkBook 14 Gen 8 IAL 在空闲时的能效表现不错。总体而言，它比我们对比的其他设备更省电，尤其是在负载情况下与 Meteor Lake H 机型相比。
对于 66.7 W 的最大功耗来说，65 W 的 USB-C 充电器似乎不够用，但由于功耗很快就会下降，用户不必担心使用过程中电池会放电。

电池寿命
联想 ThinkBook 笔记本电脑有 45 Wh 和 60 Wh 两种电池可供选择。我们的机型采用的是小电池，因此电池续航时间低于平均水平：在我们的网页浏览测试（亮度为 150 cd/m²）中，7 小时多一点的成绩很不理想。好在电池容量较大。如果您对 ThinkBook 感兴趣，并希望在旅途中使用它，请务必选择配备大电池的机型。

笔记本检查评级
联想的 ThinkBook 14 Gen 8 IAL 具有良好的性能、可升级性和丰富的端口选择，但显示屏价格低廉，扬声器不足，这些都是经济型办公笔记本电脑的典型问题。另外，电池续航时间有限，但可以通过选择配备更大电池的配置来改善。
