Whiskey Lake ThinkPad Ultrabook Laptop / Notebook Business

更轻薄更好吗? ThinkPad T490是T系列的一次重新设计。联想通过更紧凑,更薄,更轻的外壳带来了更大的移动性。这引出了一个问题,即联想是否必须做出任何妥协以实现这些改进。这一次,至少联想并没有在屏幕上吝啬。

Screen Flickering / PWM (Pulse-Width Modulation)

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 detected 2451 Hz ≤ 50 % brightness setting

The display backlight flickers at 2451 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2451 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9354 (minimum: 43 - maximum: 142900) Hz was measured.

Display Response Times

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
45.6 ms ... rise ↗ and fall ↘ combined↗ 22.8 ms rise
↘ 22.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
74 ms ... rise ↗ and fall ↘ combined↗ 33.6 ms rise
↘ 40.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.7 ms).

很明显,联想ThinkPad T490是ThinkPad T480的继任产品。但实际上,ThinkPad T490的设计完全不同,它更像是T480和T480s的混合体,而不是T480的直接后继产品。这种组合大多做得很好,但也存在缺陷。

ThinkPad T490采用坚固的外壳,采用镁质增强塑料制成,比T480更轻巧,更紧凑。接口选项非常丰富,安全功能也很多,还有除了Wi-Fi之外的全尺寸RJ45以及LTE(可选)的通信选项。与所有ThinkPad一样,输入设备非常好。与较旧的ThinkPad相比,最大的改进在于屏幕。终于,联想推出了高品质的FHD屏幕,具有良好的屏幕亮度和色域。由于更高的TDP,ThinkPad T490的CPU性能高于平均水平,可选的Nvidia GeForce MX250甚至允许一些轻量级游戏,使T490更加灵活。尽管性能良好,ThinkPad T490的风扇也很安静,电池寿命也很好。最后但并非最不重要的是,我们测试的T490保修包很慷慨。

虽然屏幕是ThinkPad T490的最佳配置之一,但它的响应时间非常糟糕,快速的鼠标会导致重影现象。 T490有很多接口,但不幸的是,联想已经用microSD卡插槽取代了SD卡插槽 ——我们认为这是不必要的改变。同样令人遗憾的是,Thunderbolt 3端口是半速的。在所有最近配备14英寸屏幕的T / X ThinkPad中,T490是最易升级的型号,但很难打开D面。负载下的高温也存在问题,因为它们经常超过50°C的门槛。良好的性能和安静的风扇没有任何帮助,因为T490在压力测试中会受到限制。T490的另一个问题是它发出的噪音:它受到电流噪音和扬声器嗡嗡声的困扰。最后,我们哀悼可拆卸功能的丢失——虽然USB C电池可以提供相同的功能,但PowerBridge是一个有趣而舒适的功能。

联想ThinkPad T490是传统T系列的最新型号——与之前的型号相比,联想已经做了很多改变。虽然并非所有这些改变都变得更好,但考虑到所有因素,ThinkPad T490是比T480更好的笔记本电脑。

总体而言,联想ThinkPad T490是一款非常出色的商务笔记本电脑,但联想应该通过软件更新修复扬声器的问题。此外,问题仍然是较弱的散热。我们确实给ThinkPad T490一个基本的建议,但是用户应该选择带有低功耗FHD屏幕或QHD LCD的型号。
