笔记本电脑使用电池时无线鼠标连接丢失

Question

我刚买了一个HP 无线鼠标，但遇到了一些问题。

光标经常变得对鼠标移动无响应。我注意到只有在我的笔记本电脑电池耗尽时才会发生这种情况，并且只要鼠标在 20-30 秒内没有移动，我就必须触摸笔记本电脑的触摸板才能重新连接鼠标。

所以看起来电源管理可能会干扰，但我不确定如何解决这个问题。

编辑： 我完全忘记提及的一条重要信息是，我之前使用的Sweex MI420无线鼠标没有出现此问题。

$ dmesg |grep -i mouse：

我通过更改设置解决了这个问题/etc/laptop-mode/conf.d/usb-autosuspend.conf

根据配置文件中的注释，某些 USB 设备不正确支持自动挂起。

配置中有一个选项AUTOSUSPEND_USBID_BLACKLIST可以为有问题的设备添加 USB 设备 ID 列表，我添加了鼠标的 ID，现在它可以正常工作了。

# If you enable this setting, laptop mode tools will automatically enable the
# USB autosuspend feature for all devices.
#
# NOTE: Some USB devices claim they support autosuspend, but implement it in a
# broken way. This can mean keyboards losing keypresses, or optical mice turning
# their LED completely off. If you have a device that misbehaves, add its USB ID
# to the blacklist below and complain to your hardware vendor.
