键盘随机关闭和打开

  • 772

我有一台 Das Keyboard 6 Professional，连接到运行 Ubuntu 20.04 的台式电脑。键盘上的灯会随机熄灭，键盘会失去响应。几秒钟后，键盘灯会重新亮起，键盘可以再次使用。

我联系了 Das Keyboard 技术支持，他们认为这不是键盘的问题，而是 Ubuntu 的问题，可能是电源管理的问题。他们说也可能是电磁干扰。

我不确定这是否是我的想象，但当我有一段时间没有使用无线鼠标然后移动它时，这种情况似乎更频繁地发生。

我无法尝试将键盘插入另一个 USB 端口，因为它是 USB-C，而我的计算机只有一个 USB-C 端口。

这实际上是 Ubuntu 的问题吗？如果是，有办法解决吗？

我愿意将 Ubuntu 升级到较新的版本。

编辑： 根据@Vercingatorix的建议，我在最近一次关机后运行了dmesg。这是我得到的结果：

    首先要检查的是您的 BIOS。BIOS 中有一个设置，当不使用 USB 时，系统会使用 USB 供电。现在它被称为 ERP（= 能源相关产品）。

    • 在启动过程中：按 F2 您将进入 BIOS。
    • 选项“高级”
    • 选项“APM 配置”
    • 将“Erp Ready”设置为“Enabled”，并将“Enable (S4+S5)”或“Enable (S5)”设置为“Enabled”

    与禁用时相比，它会随着时间的推移消耗更多的电池电量。
