Know which devices can wake up your PC from Sleep mode

Is your PC waking up automatically when in Sleep mode, and wondering which device is waking the system up? Here is a command which gets the list of devices that are configured to wake the computer up.

Open a Command Prompt window (cmd.exe) and run the following command:

powercfg –devicequery wake_armed

The output contains the list of devices that can wake your computer from sleep or hibernate mode. Sample output is below:

HID Keyboard Device
HID-compliant mouse
Intel(R) Ethernet Connection I217-LM
HID Keyboard Device (001)

If you find a device in the list that may be causing the problem, open Device Manager and disable Allow this device to wake the computer setting for each device. This can be done by double-clicking the corresponding device in Device Manager, clicking Properties and clicking on the Power Management tab.
