联想ThinkBook 14 G4笔记本电脑评测。坚实的笔记本电脑，大量的轻质金属
联想自2019年以来一直在制造ThinkBooks。这些笔记本电脑与联想的IdeaPad和ThinkPad品牌之间共享的许多功能相一致。与ThinkPads一样，它们在端口方面优于IdeaPads，但与面向终端客户的机型相比，其显示屏更差。就质量而言，ThinkBooks与E系列的入门级ThinkPads类似。这意味着联想ThinkBook 14 G4也可能最终出现在各个办公室。新的AMD Ryzen 5 5625U确保了系统的高响应性。
我们将联想ThinkBook 14 G4与其他用于办公室的14和15英寸笔记本电脑进行了比较。联想ThinkBook 15 G4也在比较设备之列。这款稍大的笔记本电脑与14英寸版本几乎相同。其他供办公室使用的设备包括戴尔 Inspiron 14，以及Dynabook Tecra A40-J-12-E和Schenker Work 15.

外壳 - 盖子和底座为铝制
银色和灰色是ThinkBook外观使用的颜色。联想保持了设计的吸引力，并在一定程度上玩弄了表面和盖子的结构。这产生了一种双色的效果，尽管这是单色阳极氧化铝。底座的顶部由一个匹配的漆面塑料组成。铝合金再次被用于底座的底部。ThinkBook回到了它的起源，其设计是典型的联想。
特点--巴塞洛Ryzen中仍然没有USB 4
尽管ThinkBook 14 G4在查看其端口时缺少一些功能，但你仍然可以利用其四个USB插口、HDMI和SD读卡器工作。然而，你将不得不放弃Thunderbolt或USB 4。USB 4只有在新的6000系列AMD CPU上才能实现。
SD卡阅读器
这台ThinkBook上的SD读卡器能够用我们的参考卡达到良好的速度。然而，AV PRO microSD 128 GB V60也能够达到更快的传输速度。

自以前的化身以来，Realtek还开发了一个带有Wi-Fi 6的Wi-Fi模块。在测试中，Realtek RTL8852AE提供了良好的传输速度，但还不能完全跟上装有英特尔AX201芯片的笔记本电脑产生的数值。

网络摄像头
凭借其清晰的对比度以及在有利的照明条件下的坚实表现，这款办公笔记本的全高清网络摄像头在测试中给我们留下了深刻印象。少量的环境光导致了非常嘈杂的图像。一个机械盖也能确保隐私。广角镜头的鱼眼效果很醒目。该摄像头不支持Windows Hello面部认证。

安全问题
除了AMD Ryzen 5之外，指纹传感器以及Kensington锁槽也确保了安全。AMD处理器支持TPM 2.0和SecureBoot等安全功能。
维护
笔记本的底座可以快速拆卸。在下面可以找到一些升级的机会。这里有一个免费的M.2插槽。除此以外，现有的NVMe SSD的RAM模块也可以被替换。几乎所有的组件也都被安装到ThinkBook 15 G4以这种方式安装。
担保
我们测试中使用的配置只在德国提供12个月的保修。不过，在联想Vantage计划中，全球范围内都有各种保修选项。
输入设备 - 平面键盘
触摸板和笔记本的背光键盘能可靠地工作。这里的键盘布局与ISO标准一致。按钮的间距和大小都很合理。在这里打字的感觉与IdeaPad键盘非常相似。低键程和小的触觉反馈意味着键盘可能需要一点时间来适应。然而，一旦你习惯了，键盘就很好。
触摸板也更接近于IdeaPad的水平。你不会在ThinkBook 14上找到像你可能从ThinkPad上了解的TrackPoint。
显示 - 色彩空间覆盖率低
联想ThinkBook 14 G4的全高清显示屏(1920 × 1080像素)没有任何特殊的功能或优点。16:9的格式，60赫兹和一个非常漂亮的远距离显示器是为一个Büro-Laptop提供的，但也是很好的。
笔记本的显示效果不是很好，而且对比度也比较低。在这里，我们看到的是对电脑的要求。

关于色彩空间覆盖率，这台办公笔记本电脑的屏幕表现出典型的数值。 62.9%的sRGB覆盖率以及42.2%和43.6%的Display P3和AdobeRGB色彩空间覆盖率都适合这台笔记本电脑的使用情况。
Calman ColorChecker在颜色偏差方面检测到相当高的数值。低色彩空间覆盖率主要反映在测量的最大值上。这意味着红、蓝、绿全色不符合规范。信息框中的校准文件仅在平均色彩偏差方面提供了微小的改进，达到了4.5的Delta E。
Display Response Times
ℹ
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 | ||
|---|---|---|
| 20 ms ... rise ↗ and fall ↘ combined | ↗ 11 ms rise |  |
| ↘ 9 ms fall | ||
| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 39 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21 ms). | ||

| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 35 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.9 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8738 (minimum: 5 - maximum: 343500) Hz was measured. | |||
由于联想ThinkBook 14 G4的屏幕是哑光的，其283.4cd/m²的亮度通常足以在户外使用。然而，在这里，你应该期望根据你的位置而受到限制。
无论从哪个角度看，屏幕都能保持其颜色。当增加观看角度时，笔记本电脑的感知亮度只有轻微下降。
性能 - 由于Barcelo的存在，性能略有提高
联想ThinkBook 14 G4有英特尔或AMD处理器，有多种内存版本可供选择。我们的测试笔记本电脑配备了AMD Ryzen 5 5625U和16GB的内存。其中，8GB的内存包含在SO-DIMM内存中。因此，该笔记本的内存可以扩展。
这些配置显然是为了适应办公笔记本电脑的要求。然而，虽然ThinkBook在办公和浏览器应用方面令人印象深刻，但在游戏和3D应用方面却不能完全跟上其他笔记本电脑。
测试条件
ThinkBook 14 G4的大多数基准测试都是在 "智能冷却 "性能模式激活时进行的。这种平衡的性能模式可以通过联想Vantage计划获得。最大性能模式也被激活，以确定最大耗电量和风扇噪音。
处理器
作为一款适用于小型和轻型笔记本的移动处理器，AMD Ryzen 5625UAMD Ryzen 5625U在ThinkBook 14 G4中可以充分利用其性能潜力。凭借Zen 3架构，这款来自2022年开始的Barcelo刷新的处理器在这里很强大。这并不令人惊讶，因为这款联想笔记本电脑中的处理器能够在其最大可配置的TDP为25瓦时持续工作。在最大性能模式下，该笔记本电脑将保持这一性能。激活 "智能冷却 "后，处理器将获得15瓦的能量。
在涡轮增压功率下，我们在这里测得约50瓦。这使处理器时钟即使长时间保持在2.3GHz以上，并在短暂的时间内达到4.3GHz。
总的来说，Ryzen 5在通用基准测试中表现出强劲的性能。在几乎相同的ThinkBook 15 G4中，处理器的基准测试是在最高性能模式下进行的。

图形卡
AMD没有更新Ryzen 5显卡。因此，著名的AMD Radeon RX Vega 7iGPU在这里工作。该图形芯片可以执行基本任务，并在一定程度上应对3D应用。在测试的游戏中，该显卡能够在中等质量设置和分辨率下产生可玩的帧率。

游戏性能
ThinkBook 14 G4可以流畅地运行一些游戏。然而，iGPU并不是为游戏而设计的，所以需要在质量设置上做出妥协，可能还有分辨率。

在TheWitcher 3 的长时间测试中，笔记本电脑能够保持其性能。在这里不应期待高帧率，因为测试是在最高图形设置下进行的。

Pros
+ 高质量的外壳，大量的金属
+ 可扩展的硬件
+ 良好的网络摄像头
+ 适当的性能
+ 快速的固态硬盘
+ SD卡读卡器
Cons
- 制造商的保修期只有12个月
- 屏幕较弱（色彩空间覆盖率低，在户外使用时有反光现象）
- 键盘的键程较低
结论--ThinkBook 14 G4与其他办公笔记本电脑相比，没有更多的优势。
凭借其16GB的内存和AMD Ryzen 5 5625U，这款办公笔记本电脑能够应对日常使用。事实证明，几乎没有任何程序对这款纤薄的笔记本电脑要求很高。这里有一个很大的好处是。即使在负载情况下，这台笔记本电脑仍然保持安静。
这款联想笔记本电脑的核心竞争力是其较长的电池寿命，在负载时的弹性和缺乏噪音。
ThinkBook 14 G4的屏幕在许多方面都有些弱。色彩空间覆盖率、色彩偏差、对比度值和显示亮度都可以做得更好。但这些数值符合办公用笔记本电脑的要求。因此，哑光屏幕达到了它的目的。
然而，竞争对手的设备和他们的 联想ThinkBook 15 G4都在同一水平上。因此，很难在个别办公笔记本电脑之间做出决定。诸如以下设备 惠普Pavilion 14和 申克工作15提供了几乎相同的性能范围。
价格和可用性
联想ThinkBook 14 G4在CampusPoint有售。在测试的时候，价格约为800欧元。
