Pros
Cons
IdeaPad S940是一款绝对华丽的设备。它是我们迄今为止评测过的最小最轻的14英寸笔记本电脑之一，它非常适合在厨房桌子或会议室中使用。虽然它很小，但它的构造仍然感觉相对坚固，具有高强度的屏幕，完美的铰链，并且机身几乎不会弯曲。它也是我们在笔记本电脑中看到的最令人印象深刻且令人难以置信的高亮度4K HDR显示器之一。使影音体验更上一层楼的是四个看似强大的杜比Atmos扬声器......虽然物理大小仍然是一个不可避免的约束，但它们提供的音频体验远远超过其他任何尺寸的笔记本电脑。它几乎在所有条件下几乎都是静音的，即使在负载下也几乎听不见。最后，尽管它很薄，输入设备也相当不错——带有非常好的玻璃点击垫，伴随着键程短但仍可维修的键盘。
IdeaPad S940是一款漂亮的笔记本电脑，但4K显示屏和i7 CPU版本有一些重要的失误，使其难以被推荐用于大多数用途。我们期待在以后有机会评测i5 CPU，FHD版本，我们希望这可能会解决其中一些令人失望的问题。
可惜它不完美。不幸的是，从这里开始，情况就下滑了。端口选择有点少，只有两个雷电3.0端口（没有专用充电端口），另外还有一个USB Type-C端口和一个耳机插孔。功耗偏高，电池续航时间短得令人失望——我们的网页浏览基准测试续航只有不到5小时。但最令人不安的是机器不愿意——或者说是没这个本事——正常的散热：持续的负荷导致温度迅速上升到90摄氏度，也不会变得得更低。结果低于我们评测中Core i7芯片的平均CPU性能。但笔记本电脑在空转时和正常使用情况下同样对冷却本身并不感兴趣 - 疏忽导致在许多情况下表面温度很高，使得放在腿上的使用不那么舒适。
所以，不幸的是，S940的实际用途——至少与前面提到的令人惊叹的UHD显示器相比——就不尽如人意了。尽管我们还没有测试过这样的配置，但FHD显示选项可能会明显改善续航时间，所以我们不能肯定地说。如果CPU性能不重要，或许Core i5可能会以更低的成本表现得更出色。这也可能对温度有所帮助，甚至会改善整体情况。尽管如此，尽管它具有漂亮的轻量级机身和屏幕，但很不去推荐X1 Carbon，或其他任何其他竞争对手（所有这些都在大多数类别中表现更好），例如戴尔XPS 13或MacBook Pro 13。
