Magyar联想ThinkBook 15 G3 ACL回顾。低排放的办公笔记本，走得更远
通过ThinkBook，联想提供了一款办公笔记本，旨在提供一个介于IdeaPad和ThinkPad之间的选择：为私人和专业用户提供一个可靠的、可负担的笔记本。它的主要竞争对手包括以下设备 华硕ExpertBook B1 B1500CEAE，以及 惠普ProBook 445 G8，以及 Acer Extensa 15 EX215-54.
我们已经测试了这款设备的前辈和继任者，即ThinkBook 15 G2 ITL和 联想ThinkBook 15 G4 ABA.虽然G3机型是基于AMD的塞尚和卢西恩APU，但G2 (Tiger Lake, Renoir)和G4 ( Alder Lake, Barcelo)可以使用英特尔或AMD芯片。

外壳和连接性--提供USB-C Power Delivery的联想电脑
银灰色的机箱没有显示任何制造缺陷。然而，电脑的底座可以扭曲和翘曲得有点过分：这里明显缺乏刚性。联想依靠金属（盖子的背面）和塑料元素（底座）以及哑光的光滑表面。电池（用螺丝固定，而不是用胶水粘住）和其他内部零件可以通过移除底层外壳来获得。从正面看，内置的网络摄像头（0.9MP，最大1280x720像素）带有一个机械盖。
这台电脑配备了两个USB-A（USB 3.2 Gen 1）和两个USB-C端口（USB 3.2 Gen 2；Power Delivery，通过USB-C的Displayport）。笔记本总共有三个视频输出（2个DP，1个HDMI）。SD存储卡读卡器（参考卡：AV PRO SD 128 GB V60）是一个中等速度的模型。
在最佳条件下的WiFi传输率（附近没有其他WiFi设备，笔记本和服务器PC之间的距离很短）很好，但不太符合WiFi芯片的全部功能（联发科MT7921；802.11 ax）。

输入设备--ThinkBook G3配备了一个发光键盘
点亮的Chiclet键盘（2个亮度级别）的平坦光滑的按键具有较短的行程以及清晰的压力点，按键的阻力水平令人愉快。键盘在打字的时候会有轻微的弯曲，尽管这并不太具有破坏性。总而言之，联想提供了一个适合日常使用的键盘。
多点触控板（约10.5 x 7厘米）的光滑表面使手指很容易滑动，同时对角落里的输入也有反应。键盘的落点很短，压力点也很清晰。
显示屏--联想笔记本的IPS面板
哑光的15.6英寸屏幕（1920x1080像素）在亮度（271.4 cd/m²）以及对比度（776:1）方面没有达到目标范围（>300 cd/m²和1000:1）。大多数竞争对手在这方面表现得更好--除了 延伸型.从好的方面看，该面板在任何亮度设置下都没有显示任何PWM闪烁。

屏幕可以正常显示所交付的颜色：但是，不能完全达到目标色彩精度（DeltaE<3），偏差为4.17。 该显示器不能再现AdobeRGB（45%）、sRGB（66%）和DCI-P3（44%）色彩空间。因此，该面板不适合依赖色彩保真度的应用场景。然而，在这方面，竞争对手的情况也没有好到哪里去。
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 | ||
|---|---|---|
| 21 ms ... rise ↗ and fall ↘ combined | ↗ 12 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. » 41 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21.5 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 30 ms ... rise ↗ and fall ↘ combined | ↗ 14 ms rise |  |
| ↘ 16 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 34 % of all devices are better. This means that the measured response time is better than the average of all tested devices (33.7 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
IPS面板具有稳定的可视角度，可以从任何位置阅读。只要太阳不是太亮，在户外阅读屏幕不是问题。
性能--联想依靠Ryzen-APU
联想的办公笔记本针对的是私人和专业用户。只有配备 Ryzen 5 5500U或 Ryzen 7 5700UAPU的机型，在测试时可以使用。相同设置的前代产品(ThinkBook 15 G2) 和后续系列 (ThinkBook 15 G4)提供了更多的选择。G2可使用英特尔Tiger Lake 或AMD Renoir芯片，而G4可使用英特尔Alder Lake或AMD Barcelo硬件。
测试条件
组合键 "Fn "+"Q "可用于在三个制造商特定的能源配置文件（"智能冷却"、"高性能 "和 "电池节约模式"）之间进行切换。测试是在标准的 "智能冷却 "模式下进行的。这些配置文件在多线程CPU性能方面略有不同，而GPU性能始终保持不变。
| 智能冷却 | 高性能 | 省电模式 | |
|---|---|---|---|
| 功率限制1 | 25瓦 | 37,5瓦 | 20瓦 |
| 功率限制2 | 48瓦 | 48瓦 | 48瓦 |
处理器
的CPU部分 Ryzen 5 5500U APU(Lucienne)由六个核心组成，基本时钟为2.1 GHz。通过Turbo可以提升到4.05 GHz。还支持同步多线程（每个核心两个线程）。
Cinebench R15基准测试的多线程测试在短时间内以4GHz的速度处理，尽管时钟速度随后下降到3.4和3.5GHz之间。单线程测试在1.8至4.05GHz下运行。 在电池模式下，CPU工作在2.5至3.5GHz（多线程）或1.4至3.5GHz（单线程）。CB15循环测试证实，持续使用CPU Turbo是可能的。高性能 "配置文件使多线程性能略有提高。

系统性能
这个运行平稳的系统可以处理办公和互联网应用，以及低图形设置下的游戏。然而，部分性能被浪费了，因为内存（8GB，DDR4-3200，板载）只在单通道模式下运行。安装另一个RAM模块会有很大的帮助--特别是在图形性能方面。对于DDR4-3200内存来说，可用的RAM的传输率处于正常水平。PCMark的结果很好。

存储设备
联想为ThinkBook配备了三星的PCIe 3固态硬盘（M.2 2242；M.2 2280型号也适用），它的存储容量为256GB。传输速率很好，但它不是一个顶级的固态硬盘。在DiskSpd循环的后半段，它的性能有一些下降。该笔记本还可以容纳第二个PCIe固态硬盘。

GPU性能
AMD的 Vega 7iGPU允许在全速（1800MHz）下连续运行，这在Witcher 3 测试中可以看到。低于平均水平的基准测试结果是由于RAM以单通道模式运行。 内置硬件可以在低设置下在屏幕上流畅地运行要求不高的游戏。如果采用主动的双通道模式（即安装另一个RAM模块，见对比表），则可以获得更多的性能。

温度
笔记本并不特别热，在压力测试中，有两个测量点的温度超过40摄氏度（104华氏度）。在日常使用中（办公室、互联网），温度处于绿色范围。

电池寿命
在我们的实际WiFi测试中，这台15.6英寸的电脑可以管理8:06小时的运行时间（包括使用脚本调用网站）--这是一个好的，但不是突出的价值。在竞争对手中，联想的这台电脑只被以下产品打败了 惠普ProBook 445 G8.
Pros
+ 哑光IPS屏幕
+ PCIe 3.0固态硬盘
+ 可容纳第二个PCIe SSD的空间
+ 运行时基本安静
+ 适度的热量排放
+ 可扩展的内存
+ 发光的键盘
+ 良好的电池寿命
+ 电源交付
Cons
- 显示屏的对比度和亮度可以做得更好
- 底座可以做得更结实
- 永久焊接的内存
- 只有一年的保修期
结论 - 一个没有严重缺陷的坚实的办公笔记本
内置的组合是一个 睿禅5 5500UCPU和8GB内存（单通道模式，板载）可以轻松处理办公和互联网应用以及轻度游戏。建议安装第二个内存模块（激活双通道模式），以释放AMD CPU的全部潜力。
联想ThinkBook 15 G3 ACL--配备Windows 11 Pro的全面的办公笔记本。
在发热和噪音方面没有什么可抱怨的，尽管风扇在满负荷情况下可以更安静一些。这款相对较轻的笔记本电脑（约1.7公斤/3.8磅）在连接WiFi的情况下，可以管理约8小时的电池寿命。一个很大的优点是：通过USB-C电源适配器进行充电。
当涉及到屏幕（15.6英寸，FHD，IPS）时，还有改进的余地。亮度、对比度和色彩空间覆盖率都太低了--不过，一些竞争对手的笔记本电脑的屏幕质量也没好多少。基本单元也可以做得更硬，而短的一年保修期也值得批评。
ThinkBook的一个替代品是 惠普ProBook 445 G8例如，它提供了更好的电池寿命，并以其在负载下的低噪音排放而得分。笔记本 延伸15 EX215-24可以被认为是经济型替代产品：它在大多数方面都不如ThinkBook，但它的Core i5-1135G7具有很高的每美元计算性能。这款笔记本已经可以买到，价格约为430欧元（446美元）或400欧元（415美元），带或不带Windows。
既然较新的G4已经上市，为什么还要买ThinkBook 15 G3？难道 "老 "G2还不够吗？
这款 G4机型我们评测的G4机型在使用与G3（6个核心，12个线程）或G2（Core i5-1135G7；4个核心，8个线程）相当的CPU配置时，提供了更多的处理能力。如果你不需要从你的机器中挤出每一滴性能，G3和G2的价格更具吸引力。G3的得分是更多的多线程性能和更好的电池寿命，而G2的优势是更大的单线程性能以及一个雷电3端口。
价格和可用性
ThinkBook 15 G3 ACL可从Heinzsoft购买（603欧元/626美元），其配置已被审查。它可以从亚马逊售价约为728美元，以及从Amazon India价格约为33,990英镑。
