底盘：塑料外壳有点吱吱作响联想采用了 联想 ThinkPad T14 第 3 代没有任何变化。从质量上看，深灰色的 ThinkPad T14 G4 的定位低于 ThinkPad T14s G4，但高于 ThinkPad L14 G4.整个外壳由塑料制成，表面有一层黑色磨砂涂层；内部有一个镁合金框架。这使得 ThinkPad 笔记本电脑非常坚固，但与全金属笔记本电脑相比，机身硬度较低。
这台设备有一个非常恼人的方面：设备右前角有一点吱吱作响。而同样结构的联想 ThinkPad T14 G4 Intel 却没有出现这种情况。联想应该能更好地控制这种质量差异。
质量较高的是带有银色金属盖的下拉式铰链，它们不会晃动。单手打开屏幕是不可能的。ThinkPad 的最大打开角度为 180 度。

网络摄像头联想将网络摄像头的分辨率从 1080p 升级到了 500 万像素。在理想的光线条件下，画面确实明显更清晰。在较暗的光线下，图像质量会迅速下降。智能手机的摄像头还是要好得多。

安全企业笔记本电脑以其广泛的安全功能而闻名。联想 ThinkPad T14 G4 就是一个很好的例子：除了 Kensington 锁插槽外，评测设备还配备了专用的 TPM 2.0 芯片。为了实现快速、安全的登录，联想为 ThinkPad 配备了指纹识别器和用于 Windows Hello 的红外摄像头。此外，网络摄像头还配备了机械式隐私快门。
配件除了 65 W USB C 充电器外，包装盒中没有其他设备。
维护与其他类别的设备相比，商务笔记本电脑几乎总是更容易打开和维修。背面和侧面总共有七颗十字螺丝和几个夹子。拧松螺丝后，ThinkPad T14 Gen 4 的内部结构就显露出来了。遗憾的是，升级该机型的方法并不多。AMD 机型的内存始终焊接在下面，而英特尔机型则不同。WiFi 芯片也是板载的。只有固态硬盘可以升级，还有一个开放式的 M.2 2242 插槽，可用于选配 WWAN 模块。电池只需用螺丝拧紧，散热系统可以轻松清洁。
该机型还有一个如今很少见的特殊功能：用户可更换键盘。这是与其他更薄的 ThinkPad 的重要区别。键盘是一个消耗性部件，因此可以轻松更换是非常有用的。
ThinkPad T14 G4 AMD：内部结构
ThinkPad T14 G4 AMD：可拆卸键盘保修此次评测的笔记本电脑是一款专为学生设计的机型，保修期为三年，提供现场服务和顶级支持，内置电池的保修期也更长。保修期为三年，可选择升级到五年。此款德国机型仅在德国提供现场服务和顶级支持。在国际上，则提供上门服务。
输入设备没有缺陷的 ThinkPad键盘与上一代产品相比，联想没有改变输入设备。总的来说，这意味着带有 1.5 毫米行程和微凹按键的 Chiclet 键盘采用了 ThinkPad 的典型布局，并带有两级 LED 键灯。这种布局的好处之一是方向键间距适中。另一方面，FN/Ctrl 键的排列方式对许多用户来说并不常见。光滑按键的打字手感非常好，虽然不像以前那么豪华。尽管如此，它仍然是市场上最好的笔记本键盘之一。
ThinkPad T14 G4：键盘
ThinkPad T14 G4：触摸板 + TrackPoint触摸板与键盘一样，触摸板和 TrackPoint 也没有变化。触摸板采用塑料表面，尺寸略低于平均水平，集成了点击机制，但实际上只有下半部可以点击。触摸板足够光滑，手指可以毫不费力地滑动，但也非常容易脏污。主观上的质量感觉与玻璃触摸板不太一样。不过点击机构非常出色，没有任何晃动。同样优质的还有红色的 TrackPoint，它可以与触摸板上方的专用鼠标键一起使用。用户只需按压橡胶盖即可轻松控制鼠标，专用按键既安静又顺滑。总而言之，这些都是非常出色的输入设备，能让用户获得愉悦的工作体验。

室外（多云）在室外，联想笔记本电脑的屏幕非常好用。磨砂屏幕表面最大限度地减少了反光。加上良好的屏幕亮度，即使在明亮的环境中，用户也能看清显示的内容。只有阳光直射可能是个挑战。
Display Response TimesℹDisplay 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).

Screen Flickering / PWM (Pulse-Width Modulation)ℹTo 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 detectedIn comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8152 (minimum: 5 - maximum: 343500) Hz was measured.

结论：ThinkPad T14 第 4 代 AMD 版优于英特尔版评测中：联想 ThinkPad T14 第 4 代 AMD，评测样品由联想提供
联想再次推出了一款 ThinkPad 笔记本电脑，ThinkPad T14 Gen 4 AMD 获得了我们 "非常好 "的评价。总的来说，它是一款出色的工作工具。但它也并非没有弱点。
其中之一就是：机箱有轻微的吱吱声，这确实降低了设计的主观质量。昂贵的商务笔记本电脑不应该出现这种情况，即使这款笔记本电脑在制造过程中使用的塑料多于金属。与惠普的 EliteBook 845 G10 相比，焊接内存也是一个缺点，就像扬声器声音太小一样。
除此之外，我们还非常喜欢这款笔记本电脑。它有很多端口，RJ45 以太网是其一大特色。WWAN 可以升级，以获得最大的灵活性，ThinkPad 还有许多安全功能。使用 ThinkPad 的输入设备非常有趣，联想还提供了实用的低功耗面板。AMD Ryzen 7 Pro 7840U 性能出色，电池消耗也不快。风扇噪音和温度并无特别之处，但也远非糟糕。通过用户可更换键盘，ThinkPad T14 Gen 4 拥有了大多数现代笔记本电脑少有的特殊功能。
联想 ThinkPad T14 Gen 4 AMD 是企业用户的理想之选。不过，它也有一些弱点。
尤其是这项功能和 RJ45 端口，是与其他采用这种 CPU 的笔记本电脑相比的重要区别。竞争激烈：HP EliteBook 845 G10 扬声器的音量更大，机箱和内存插槽更高档，但缺少用户可更换键盘和 RJ45。同样，Lenovo ThinkPad T14s G4 AMD 也缺少这些功能，但它的设计更轻巧、更高档。
定价和可用性此次评测的 21K4S02000 版本是德国联想校园计划的一部分，仅面向学生提供。它的价格为 1,300 欧元（含教育退款）。亚马逊网站提供的不同配置的 ThinkPad T14 第 4 代 AMD价格约为 1,270 美元。
