联想 IdeaPad Flex 2 14 笔记本电脑简短评测

Name: Lenovo Flex 2 14
Brand: Lenovo

不全是“瑜伽”。 联想的Yoga系列有四款不同型号，而Flex 2 14只有两款。它对于需要灵活易用的笔记本电脑而非平板的用户来说更加适合。我们的评测将会告诉你为什么仅仅不到一年联想就推出了IdeaPad Flex 14的新一代产品，Flex 2 14和Yoga 2 13之间又有什么区别，它独特的魅力又在哪里。

虽然不像联想Yoga 2 13一样灵活，不过作为补偿可以节省100欧元（约134美元）。如果你不需要Yoga的平板模式的话就可以省下这笔钱，除此之外，这两款变形本非常相似——联想Flex 2 14的屏幕大0.7寸，且相比更重半公斤。

不过，Flex 2 14并不是IdeaPad Flex 14的一个真正的替代产品，因为它们之间的区别非常小——甚至处理器都还是同一代的。机身在尺寸上略微增大而重量也提高了。屏幕终于有了全高清分辨率，不过它并无法真正的在户外使用，且可视角度范围也不大。

电池的容量变小了，不过这并没有对实际电池续航时间有太大的影响。但是，从IdeaPad Flex 14开始它们的续航时间作为超便携设备并没有太大的竞争力。一个更大的优势是它的独立显卡。GeForce 840M对于在中等设定下运行较老或一部分最新游戏来说都可以提供充分的动力，这对于普通游戏玩家来说可能已经足够了。

整体上，Flex 2 14是一个优秀的实惠型变形本产品，不过你可以发现它低价的原故：很多细节的设计并不是非常出色，例如它的待机按钮位置和仅有的一个USB3.0接口。它屏幕的低稳定性和旋转机身时的金属声都给人一种廉价感。

如果在这个价位你可以接受这些缺点，那么你可以获得一款对于日常使用来说配置优秀（有快速的固态硬盘，千兆以太网接口，优秀的输入设备）的变形本。由于它屏幕放大比例的问题使得很多程序的使用受到了影响，我们因而从它的总分中减去了一分。

注：本文是基于完整评测的缩减版本，阅读完整的英文评测，请点击这里。

当然你也可以把Flex 2 14当作传统笔记本使用。相比Yoga系列，它只缺少平板模式。

这些水平的线条的错误很幸运地可以通过更新驱动来修正，不过放大比例的问题仍然没有解决。

Nvidia GeForce 840M独立显卡足够满足较老或一些最新游戏的运行要求。
