联想 IdeaPad Flex 5Chromebook Plus 评测：性能强劲的优雅可折叠电脑
Chromebook 和敞篷车。
这两者配合得很好，涵盖了许多使用领域。联想二合一笔记本电脑还可作为功能强大的平板电脑使用，配备了强大的英特尔酷睿处理器，支持笔输入，并完全兼容许多Android 应用程序。有了 Gemini，用户身边还多了一个多才多艺的人工智能。Marc Herter, 👁 Marc Herter (translated by DeepL / Ninh Duy) Published 🇺🇸 🇩🇪 ...
结论--多才多艺的同伴，弱点较少
联想 IdeaPad Flex 5 Chrome 是一款多功能可转换笔记本电脑，其优雅的设计、扎实的做工和灵活的 360 度铰链给人留下了深刻印象。这款二合一笔记本电脑还可用作Android 平板电脑的有力替代品。
英特尔酷睿 i3 处理器和 NVMe 固态硬盘保证了流畅的性能。此外，还配备了两个 USB-C 端口、一个背光键盘和一个大触摸板。16:10 屏幕提供了良好的可视角度和均匀的照明。
除此之外，屏幕并无特别之处。分辨率、色彩还原度和亮度都相当标准。
电池续航能力稍弱和显示屏表面反光也是扣分项。此外，没有附带手写笔也是一个遗憾。购买价格比 宏碁Chromebook Plus 514这一点并不完全清楚。就性能、显示屏和功能而言，在Chromebook 的典型使用场景中，只有少数几处差异会比较明显。

联想 IdeaPad Flex 5Chromebook 是一款采用 360° 铰链和 14 英寸 16:10 格式屏幕的可折叠设备。它配备了英特尔酷睿 i3 处理器、8 GB 内存和 512 GB NVMe 固态硬盘。其他功能包括带隐私快门的全高清网络摄像头和 Wi-Fi 6E。
规格
机箱和设备 - 高质量材料，使用灵活
联想 IdeaPad Flex 5Chromebook 拥有现代而优雅的设计，酷炫的铝合金和坚固的塑料相结合，给人留下深刻印象。这款二合一笔记本电脑采用优雅的深灰金属色。屏幕盖由铝合金制成，而屏幕本身则由玻璃保护。底座主要由烤漆塑料制成。这种材料的混搭不仅给Chromebook 带来了令人愉悦的清凉感，其稳定性也令人印象深刻。
Flex 5 的核心是 360 度铰链，它赋予了Chromebook 同名的灵活性。只需轻轻一摆，触摸屏就能完全折叠起来，经典的笔记本电脑瞬间变成实用的平板电脑。无论是在沙发上舒适地冲浪、展示内容，还是使用可选的联想 USI 笔进行创意绘画，Flex 5 都能毫不费力地适应任何情况。
联想 IdeaPad Flex 5Chromebook 的做工一如联想一贯的高标准。缝隙精确均匀，找不到锋利的边缘或难看的毛刺。屏幕的抗扭转性能令人满意，即使在强大的压力下也几乎不会弯曲。底座同样坚固稳定，不过键盘可能会被压得有些变形。只有屏幕盖子还可以更平滑一些，但大部分情况下还是可以用一只手打开。
联想 IdeaPad Flex 5Chromebook 的尺寸为 21 x 315 x 231 毫米，重量为 1.64 千克，是一款小巧的移动伴侣。 它的重量是 14 英寸可折叠笔记本电脑的平均重量，便于背包或手提包携带。
设备两侧都有一个 USB-C 端口。这两个端口都提供 DisplayPort 和 PowerDelivery，用于外接屏幕和充电器。左侧还有一个 USB-A 端口、一个 MicroSD 读卡器和一个用于耳机和麦克风的组合音频接口。在安全方面，Chromebook 提供了一个 Kensington Lock 插槽和一个指纹传感器。
SD 读卡器、网络摄像头和 WiFi - 均为平均值
集成的 SD 卡读卡器读取速度为 50 MB/s，性能相当不错。这样就能从存储介质中快速传输照片和视频。
网络摄像头具有全高清分辨率，可为视频会议提供可用图像。机械式隐私快门是一大亮点，它能在不使用时安全地遮住摄像头，从而保护隐私。
由于采用了 Wi-Fi 6E 标准，Wi-Fi 模块性能稳定，在 2.4 GHz 和 5 GHz 频段以及新的 6 GHz 频段都能提供快速的传输速率。

可持续性
联想 IdeaPad Flex 5Chromebook 包装在一个纸箱中。里面有泡沫、铝箔和塑料布保护设备。在我们看来，这种包装不太环保。
在维护方面，联想Chromebook 表现出了可持续发展的可喜一面。联想提供了详细的维护说明和多种备件选择，使维修和升级更加容易，并延长了设备的使用寿命。设备上的二维码有助于查找所提供的信息。
另一个亮点是长期的更新保证：Chromebook 的软件更新将持续到 2032 年 6 月，因此它在未来仍能保持最新和安全。
输入设备 - 触摸屏和可选手写笔
键盘
Flex 5 Chrome 的键盘符合典型的联想 IdeaPad 标准。键程不是特别高，但键盘提供了一个清晰可感的压力点，可实现精确键入。
集成背光是一个亮点，它可以进行多级调节。这样，即使在光线较暗的环境下，键盘也能保持最佳照明状态，从而提高工作效率并消除工作疲劳。
触摸板
Chromebook 的触摸板尺寸宽大，12 厘米 x 7.5 厘米，为导航提供了充足的空间。触摸板表面光滑平整，可以精确、舒适地控制鼠标指针。触摸板边缘反应灵敏，使操作更简便，工作更流畅。
触摸屏
二合一笔记本电脑的触摸屏对输入做出快速、流畅的响应。多点触控手势可以可靠地识别和执行。得益于精确的触摸屏，在平板电脑模式下，Chromebook ，操作直观舒适。一个小缺点是表面有些脆弱，很快就会留下指纹。对于喜欢手写笔记或绘画的人来说，联想 IdeaPad Flex 5Chromebook 兼容选配的联想 USI 手写笔。这样就可以实现精确的笔输入，并扩大了Chromebook 的应用范围。
显示屏 - 16:10，分辨率不高
我们的测试设备配备了一块 14 英寸 16:10 格式的显示屏，分辨率为 1,920 × 1,200 像素。亮度约为 340 cd/m²，足以在室内使用。屏幕的均匀照明是一个积极的特点。因此，不会出现恼人的光晕，这在显示暗色内容时尤为明显。
反光玻璃表面在室外可能会造成问题。因此建议在阴凉处使用。
视角稳定性良好。即使从侧面观看，色彩和对比度也能保持稳定，使显示屏在不同位置都能轻松阅读。
主观上看，图像清晰，对比度丰富。由于 sRGB 色彩空间覆盖率为 64%，色彩显得有些暗淡。CalMAN ColorChecker 显示的平均色彩偏差为 4 DeltaE 2000，未经训练的肉眼很难发现色彩偏差。

性能
联想 IdeaPad Flex 5Chromebook 不仅外形抢眼，而且性能不俗。这款可折叠电脑采用英特尔酷睿 i3-1315U。这款高效的多核处理器拥有六个内核，可为Chromebook 浏览、办公和流媒体等典型应用提供足够的动力。
处理器由 8GB LPDDR4X 内存和快速的 512GB NVMe SSD 支持。这一组合确保了较短的加载时间和流畅的系统体验。
处理器
酷睿 i3-1315U 酷睿 i3-1315U然而，在Chromebook 中，该处理器的 PL2 配置明显较低。我们在诊断显示器中看到，即使在满载情况下，Turbo 模式下的最高频率为 3.75 GHz，连续运行模式下的最高频率为 2.2 GHz。无论如何，这足以让联想 IdeaPad Flex 5Chromebook 为日常任务提供稳定的性能。与最近测试的 宏碁Chromebook Plus CB514配备 英特尔 N305 处理器联想Chromebook 在大多数合成基准测试中都表现出更高的性能。不过，处理器的 iGPU 在这方面有明显的不同。英特尔UHD Graphics 配备了 64 个 EU，而不是 N305 的 32 个。因此，只有在图形性能基准测试中才能看出这两款Chromebook-Plus 替代品在性能上的明显差异。

图形卡
联想 Flex 5Chromebook 依靠集成的英特尔UHD Graphics 64EUs。没有安装专用显卡。与 宏碁Chromebook Plus 514UHD Graphics 32 EUs 相比，联想Chromebook 的图形性能略胜一筹。
一些合成基准测试显示，FPS 从宏基到联想Chromebook Plus 提高了一倍。不过，在游戏性能方面，这两款设备并无太大差别。除了图形性能外，CPU 性能等其他因素也起着决定性作用，这两款设备的 CPU 性能处于相似水平。

联想Chromebook 的扬声器带来了令人惊喜的良好音质。均衡的高音提供了清晰、和谐的声音，而音量则足以填满一个小房间。
如果你想定制音效或享受深沉的低音，可以连接耳机或外置扬声器--由于有插孔连接和蓝牙，所有选择都是开放的。

耗电量
IdeaPad Flex 5 Chrome 配备了 45 瓦的电源。测试表明，当处理器满负荷运行时，笔记本电脑也会在短时间内消耗这些功率。不过，由于这些阶段不会持续很长时间，因此电源装置的尺寸足够大。
总的来说，Chromebook 并不是很耗电。最近测试过的 AcerChromebook 则更省电一些，但它的处理器没有强大的 P 核心，因此可以节省几瓦。

电池寿命
联想 IdeaPad Flex 5Chromebook 的电池续航时间并不突出，在 WLAN 测试中仅为 9 小时 15 分钟多一点，但足以满足一般工作日的需求。
其他拥有同样大甚至更小电池的 Chromebook 有时能达到更长的运行时间。这可能是英特尔酷睿 i3 处理器的功劳，它比 Chromebook 通常安装的处理器需要更多的能量。

Notebookcheck 总体评分
联想 IdeaPad Flex 5Chromebook Plus 以其优雅的设计、稳定的性能和灵活的使用方式给人留下了深刻的印象。功能实用，屏幕和扬声器也不错。但电池续航时间稍短，影响了整体效果。如果联想能提供配套的触控笔就更好了。
