自 2010 年推出以来，联想 ThinkPad L 系列一直处于价格更高的 ThinkPad T 系列的阴影之下，这是不公平的。价格更实惠的企业系列畅销大型企业，是许多人的工作笔记本电脑。即使设备的某些方面质量较差，L 系列也获得了许多过去只有更昂贵的 ThinkPad 才拥有的功能。在本次评测中，我们将看到最新的变体--联想 ThinkPad L14 5 代。根据其在联想产品线中的位置，它是以下型号的廉价替代品 ThinkPad T14 第 5 代.与 T14 一样，L14 也有英特尔和 AMD 两种处理器可供选择，我们测试的是 AMD Ryzen 处理器。

机箱：经济型 ThinkPad 使用塑料
如今，塑料的名声并不好--不利于环境、质量低劣，这是许多人对这种材料的看法。不过，如果使用得当，塑料也不是那么糟糕，因为它重量轻，而且相当坚固。联想 ThinkPad L14 5 代给人的第一印象不错。尽管 L 系列没有采用 T 系列的镁合金结构框架，但底座的硬度与 T14 相似。掌托和键盘同样坚固，做工不错。底座和屏幕都不太容易弯曲。在这方面，L14 5 代比前一代 L14 4 代有所改进。屏幕背面受到的压力很快就会影响到面板，因此这是一个比较薄弱的地方。屏幕盖和掌托都采用了光滑的涂层，而底部则是简单粗糙的塑料。手感并不好，这也暴露了该机型的预算水平。
联想在 T14 G5 上引入的许多设计变化 T14 G5同样适用于 ThinkPad L14 5 代。ThinkPad 徽标采用黑色，铰链也是如此。与 ThinkPad T 系列相比，这里的 "摄像头凸起 "明显减少了。如果不喜欢这种设计，L14 G5 可能是一个不错的选择。总的来说，L14 Gen 5 看起来像一台典型的新一代 ThinkPad，采用方形设计，屏幕盖板有一些微妙的弧度，侧面呈锥形。
两个下拉式小铰链可实现 180 度的打开角度。单手无法打开屏幕，因为铰链太紧了。优点我们没有发现屏幕有太大的晃动。
联想 ThinkPad L14 Gen 5 的重量为 1.56 千克，比昂贵的 ThinkPad T14 Gen 5.L ThinkPad 还比 T 型重一毫米。
连接性唯一配备三个 USB-A 端口的 14 英寸 ThinkPad
L 系列的 AMD 机型是为数不多的仍缺少 Thunderbolt 或 USB4 的 ThinkPad 之一。随着联想 ThinkPad L14 第 5 代 AMD 机型的推出，这种遗憾终于得到了改变。升级到 Zen3+ 后，USB4 出现了。两个 USB-C 端口中有一个支持 USB4。与 ThinkPad L14 Gen 4，L14 5 代还增加了一个 USB-A 端口。这也是多年来第一台拥有三个 USB-A 端口的 14 英寸 ThinkPad。另一方面，上一代产品的 microSD 读卡器被取消了。另一方面，RJ45 以太网接口依然存在。
交流
联想ThinkPad L14 Gen 5 AMD配备了高通公司的Wi-Fi 6E网卡，在发送和接收数据时都能实现稳定的高传输速率。
除 Wi-Fi 和 RJ45 以太网外，ThinkPad L14 G5 AMD 还可选配 WWAN - CAT6 或 CAT16 4G/LTE。我们的机型可以升级 WWAN。不过，由于 ThinkPad 有 WWAN 白名单，只有专门为这款笔记本电脑制造的联想 FRU 的 WWAN 模块才能使用。
网络摄像头
之前的型号配备的是 1080p 网络摄像头。ThinkPad L14 G5 AMD 是第一款配备摄像头的 L 机型，配备了 500 万像素网络摄像头，但仍有 720p 网络摄像头供吝啬的企业客户选择。在光线充足的环境下，我们使用的这款分辨率更高的摄像头能生成清晰的图像。它当然足以满足视频会议的要求，但不能满足更多要求。
安全
从安全功能的清单和数量可以看出，联想 ThinkPad L14 Gen 5 AMD 是一款真正的商务笔记本电脑。智能卡读卡器、指纹传感器、红外摄像头、Kensington 锁插槽和隐私快门是外部的安全功能。在内部，我们发现了专用的 TPM 2.0 安全芯片。联想 ThinkPad L14 Gen 5 AMD 还具有底部防篡改检测功能，可确保底盖无法移除--或者说，它要求用户在底盖被移除后输入主管密码。
配件
联想 ThinkPad L14 5 代 AMD 的包装盒里只有 65 W USB-C 充电器和一些纸片。
维护
与 ThinkPad T 系列不同，联想从未在 L14 上使用焊接内存。联想ThinkPad L14 Gen 5 AMD仍然有两个SO-DIMM插槽，但现在已经升级到了急需的DDR5内存。除此之外，值得注意的是，联想重新使用了 M.2 2280 SSD，而不是前两代的 M.2 2242 模块。出厂时，WWAN 模块的 M.2 插槽是开放的，天线和 SIM 卡插槽都已就位。下面焊接的是 Wi-Fi 模块和 USB-C 端口。旋入式电池可由用户更换。但与最新的 T 系列不同的是，在保修期内，只有维修技师才能更换电池。
在固定底盖的十颗螺丝中，有两颗标有键盘符号。如果松开这两颗螺丝，键盘就可以拆卸下来--这一功能是 ThinkPad 与竞争对手的区别所在。由于键盘作为一个机械部件很容易出现故障，因此这是一个非常重要的可维修功能。
可持续性
即使是 2010 年推出的第一代 ThinkPad L 系列，如 ThinkPad L512也被称为 "绿色 ThinkPad"。除了良好的可维修性，这一传统的一部分还包括使用可回收材料的机箱和可堆肥的包装。CO₂ 产值为 145 千克 CO₂ 当量。联想一如既往地为 ThinkPad 提供全面的视频和文字拆卸指南。联想提供多年的部件和软件更新支持。
保修
L 系列和 T 系列 ThinkPad 的保修服务差别很大：经济实惠的 L 系列只提供一年的标准保修，而 T 系列则提供三年。当然，ThinkPad L14 Gen 5 AMD 的保修期可以延长，但需要支付一定的费用。还可选择现场服务，因为这是一种商业模式。出厂时，只提供全球适用的保修服务。
输入设备：带有一些新功能的典型 ThinkPad 键盘
键盘
早在 2020 年，联想就已经在 ThinkPad L 系列上实现了向 1.5 毫米键程的过渡。 L14 Gen 1.在这方面，L14 5 代没有任何变化。不过，与 联想 ThinkPad L14 4 代.制造商精元在这里使用的键盘具有很好的平衡性，驱动力不太大，但仍能给键盘带来坚实的反馈。有了这款键盘，您可以长时间工作并输入长文本，例如本评论。
键盘布局有一些变化：联想调换了 Ctrl 和 FN 键的位置。这将使从其他品牌转换到 ThinkPad 更加容易。长期使用旧布局的 ThinkPad 用户仍可在 UEFI-BIOS 中切换按键功能。此外，还新增了 Copilot 键，可将 PrtScr 键移至 F9。除了这些变化，联想还为 Ins、FN、Enter 或音量增大/减小键等按键添加了触觉标记。这样做的目的是让盲人更容易使用键盘。
触摸板和轨迹点
随着 16:10 面板的加长，联想也增加了触摸板的长度。塑料触摸板的表面从 11.5 x 5.5 厘米（L14 G4）增至 11.5 x 6 厘米（L14 G5）。就表面触感而言，这款触控板无法与高级笔记本电脑相媲美。塑料表面给人廉价的感觉。只能在触摸板的下半部分激活的集成点击机构的机械质量非常好。总的来说，这是一块非常实用的触摸板。
红色的 ThinkPad TrackPoint 也同样好用，它提供了另一种通过压力控制鼠标指针的方法。与触摸板相比，TrackPoint 的优势在于用户可以将手放在键盘上。此外，在火车或平原等狭窄环境中使用它也更方便。触摸板上方的三个专用鼠标按键也很好用。中键可用于滚动。双击菜单是这一代产品的新功能，当你点击 TrackPoint 两次时，菜单就会出现。在这里，可以进行一些快速设置，还可以激活 "语音转文字 "模式。
显示屏亮度更高，但色域覆盖率仍然较低
只剩下三个：联想减少了 ThinkPad L14 5 代的屏幕选项。高清分辨率（1,366 x 768）的 TN 液晶屏不复存在--没有人会错过这个选项。此外，联想还将基本屏幕的亮度从 250 / 300 cd/m² 提高到 400 cd/m²。其余三款 14 英寸产品均采用 IPS 技术，并首次在 14 英寸 L 系列产品中采用 16:10 屏幕--ThinkPad 产品线终于完成了向 16:10 格式的过渡，TN 技术也在慢慢消亡。
- WUXGA (1,920 x 1,200), IPS, 400 cd/m², 45 % NTSC, 雾面
- WUXGA（1,920 x 1,200），IPS，400 cd/m²，45 % NTSC，亚光，On-Cell Touch
- WUXGA (1,920 x 1,200), IPS, 400 cd/m², 100 % sRGB, 雾面, 低功耗
屏幕几乎达到了宣传的 400 cd/m²。399 cd/m² 是测得的平均最大亮度。与前代产品相比，同等屏幕的亮度为 250 cd/m²，这是一个很大的进步。

出厂时，色彩质量非常糟糕。使用 X-Rite i1Pro 3 校准后，卡尔曼测量值略有改善，但只有灰度值得到了真正的改善。
由于色彩准确度低，该屏幕不适合任何与色彩有关的工作。色域覆盖率低也证实了这一点，即使是较小的 sRGB 色域也没有覆盖。对于 ThinkPad L14 Gen 5 的廉价面板选项来说，这一弱点依然存在。
ThinkPad 的亮度为 400 cd/m²，只要避免阳光直射，在户外也能使用。

性能L14 现在配备 DDR5 和 PCIe Gen 4
在停滞了三年之后，联想 ThinkPad L14 Gen 5 AMD 终于为 AMD L 系列带来了新的 CPU。有三种芯片可供选择AMD Ryzen 3 Pro 7335U, Ryzen 5 Pro 7535U, Ryzen 7 Pro 7735U)系列的 AMD Ryzen 7035U 基于 Ryzen 6000 - L14 第 2 代。 L14 Gen 2, L14 第 3 代和 L14 4 代都使用基于 Ryzen 5000 的 CPU。随着从 Zen3 升级到 Zen3+，我们也从 Vega 升级到 RNDA2。买家可以选择 Radeon 660M或 Radeon 680M取决于所选的 CPU。
联想 ThinkPad L14 5 代 AMD 的两个 SO-DIMM 插槽可容纳 64 GB DDR5-4800，而不是前代产品的 64 GB DDR4-3200。在固态硬盘方面，联想终于从 PCIe 3.0 转向了 PCIe 4.0。格式也从 M.2 2242 变为 M.2 2280。出厂最大容量为 2 TB。
测试条件
联想通过本地 Windows 设置提供了三种不同的能耗配置文件。它们都会影响处理器在持续负载（功率限制 1/PL1）和短期负载（功率限制 2/PL2）下的功耗：
- 最佳电池寿命：PL1 10 W / PL2 10 W
- 平衡：PL1 14 W / PL2 18 W
- 最佳性能：PL1 22 瓦 / PL2 40 瓦
处理器
餈 AMD Ryzen 5 Pro 7535U是一款拥有六个 Zen3+ 内核的处理器。它属于 "伦勃朗刷新 "系列，基于 2022 年首次发布的 Ryzen 6000。作为 U CPU，它的功耗优化在 15 到 30 W 之间。六个内核的时钟频率在 2.9 GHz 到 4.55 GHz 之间。通过我们的 CPU 比较列表。
尽管采用了更新的架构，但在我们的基准测试中，联想 ThinkPad L14 第 5 代 AMD 处理器的速度与前代产品相比还是稍慢了一些。问题在于与旧款 ThinkPad 相比，L14 G5 的功耗限制更低，旧款 ThinkPad 在持续负载情况下功耗可达 25 W，而 L14 G5 功耗限制为 22 W。笔记本 ThinkPad T14 5 代尽管 T14 G5 的 CPU 性能也不出色，但配备酷睿 Ultra CPU 的 ThinkPad T14 Gen 5 比 L14 Gen 5 AMD 更快。
在使用电池供电的情况下，设备没有出现节流现象。

噪音
联想 ThinkPad L14 Gen 5 AMD 的风扇在空转时基本上是静音的。当风扇开始运转时，即使仅在中等负载（配置文件：平衡）下，其噪音也高达 38 dB(a)。在最大负载情况下（配置文件：最高性能），风扇噪音仅略有增加。噪音水平高于前代产品 联想 ThinkPad L14 4 代 AMD.
遗憾的是，这款 ThinkPad 笔记本电脑确实存在线圈啸叫。将耳朵贴在键盘上会明显感觉到。

联想将两个立体声扬声器隐藏在前边缘下方，它们是底部发射的。当 ThinkPad 笔记本电脑放在平整、坚硬的表面上时，这不是问题。如果表面比较柔软，比如人的膝盖，声音就会减弱一些。反正扬声器的音量也不大--这也是大多数笔记本电脑的典型扬声器，没有底座。

耗电量
联想 ThinkPad L14 第 5 代 AMD 并不是同类产品中最省电的。4.4 W 的最低负载高于大多数竞争对手的水平。
ThinkPad 笔记本电脑的功耗高达 65.9 瓦，超过了 65 瓦充电器的功率。不过，耗电量很快就会下降。在负载情况下，电池电量应该不会有任何损失。

电池寿命
不同于 ThinkPad L14 第 4 代 AMDL14 5 代 AMD 只有两种电池可选。联想仍然提供 46.5 瓦时电池和 57 瓦时电池，但取消了 63 瓦时电池选项。我们的评测设备配备了较大的 57 Wh 电池，在我们的 Wi-Fi 测试（150 cd/m²）中，电池续航时间超过了 12 小时。在这方面，前代产品略胜一筹。

结论ThinkPad L14 第 5 代 AMD 的众多新功能
联想 ThinkPad L14 5 代 AMD 是一款笔记本电脑，与前代机型相比，它在技术上有了巨大的更新。许多东西都是新的，但对于 ThinkPad 而言，许多东西也保持不变。
首先是变化：ThinkPad L14 Gen 5 是经济实惠的 L 系列中首款配备 16:10 宽高比屏幕的 14 英寸 ThinkPad。在这种情况下，基本配置的显示屏比以前更亮了。此外，廉价过时的高清 TN 显示屏也不复存在。在内部，联想将 Ryzen 5000 架构换成了基于 Ryzen-6000 的新芯片。在向前迈进的同时，还采用了许多更新的标准--DDR5、NVMe PCIe 4.0 和 USB4。ThinkPad L14 G5 AMD 首次支持这些标准。新增的第三个 USB-A 端口是 ThinkPad 笔记本电脑的一大特色。我们还很欣赏联想将较小的 M.2 2242 SSD 转换为较大的 M.2 2280 SSD，从而提高了可升级性。
关于可升级性：联想保留了两个 SO-DIMM 插槽，用户可更换键盘也是如此。遗憾的是，联想还保留了默认屏幕的糟糕色域覆盖，这是经济型商务笔记本电脑的典型标志。至少屏幕亮度得到了改善。比屏幕好得多的是输入设备。它们达到了典型的 ThinkPad 标准。另一方面，L14 的性能并不理想，在这方面停滞不前。由于功耗限制较低，L14 G5 AMD 的性能并没有超过 L14 G4 AMD.在风扇噪音和发热方面，ThinkPad 只有一些小缺点。电池续航时间也还不错，尽管比前代产品稍差一些。
L 系列价格实惠，但对许多办公用户来说仍是不错的选择。如果你想省钱，联想 ThinkPad L14 第 5 代 AMD 是一款出色的工作主力，可以胜任工程和多媒体任务之外的大多数工作相关事务。
总的来说，我们非常喜欢联想 ThinkPad L14 5 代 AMD。与更昂贵的 T 系列相比，L14 G5 的差异感觉比以往任何时候都要小，比 L14 G4 更现代。在材料和屏幕质量方面，买家必须做出牺牲。除此以外，这还是一款价格比较实惠的办公笔记本电脑。屏幕色彩质量不佳，性能不佳，这确实意味着它不适合工程和多媒体任务，但在办公和网络应用方面，它却大放异彩。
与 L14 Gen 5 价格相近的竞争产品有惠普 600 系列 EliteBook 和戴尔Latitude 5000。惠普 惠普 ProBook 445 G10也有可能与之不相上下。它的优点是价格更低，重量更轻。不过，它缺乏可选的 WWAN 或 USB4 等功能。
定价和可用性
经过测试的联想 ThinkPad L14 Gen 5 在德国的售价约为 1,000 欧元。在美国，ThinkPad L14 Gen 5 AMD 的起价约为 735 美元。
注：我们最近更新了评级系统，第 8 版的结果与第 7 版的结果不具可比性。更多信息 此处.
