Know which devices can wake up your PC from Sleep mode
April 14th, 2008 • Filed Under • by Ramesh Srinivasan
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 type:
powercfg –devicequery wake_armed
Press {ENTER}
If you find a device in the list that may be causing the problem, open Device Manager and disable the wake up option for the device. This can be done by double-clicking the corresponding device in Device Manager, clicking Properties and clicking on the Power Management tab.
Note: You can open Device Manager via Control Panel, or by running the command devmgmt.msc.
