Solve the problem that the computer cannot wake up from sleep mode

Problem overview

I recently got a new computer and found that whenever it goes into sleep mode it won't wake up, even though the keyboard and mouse lights are still on.

Solution steps

1. Check your computer's support for sleep mode:

   # 用于查看电脑支持的电源睡眠模式
   powercfg -a
   # 查看在系统休眠后，哪些设备有权唤醒系统，例如键盘、鼠标等
   PowerCfg -DEVICEQUERY wake_armed
   

   

   If you find that your computer does not support sleep mode, the simple solution is to set all sleep modes to hibernate mode in the control panel.

2. Update or reinstall the driver:

   If the computer supports sleep mode, try updating or reinstalling the Intel(R) Management Engine Interface driver. Specific steps are as follows:

   • Open Device Manager, locate "System Devices" and expand it.
   • Find the Intel(R) Management Engine Interface, right-click and select Properties.
   • In the power management options of the pop-up window, uncheck "Allow the computer to turn off this device to save power", click "OK", and then observe whether the computer's sleep problem is resolved.

3. Looking for network solutions:

   If none of the above methods solve the problem, you can search online for users of the same model of computer who have encountered the same problem and refer to their solutions.
