System Find Wake Source for Windows 11 Computer

This tutorial will help show you how to find the wake source for what woke up your Windows 11 computer from a sleep or hibernate state.

When you put your computer to sleep or hibernate, many sources (ex: device or wake timers) can wake the computer.

References:







1 Open Windows Terminal, and select either Windows PowerShell or Command Prompt.

2 Copy and paste the command below into Windows Terminal, and press Enter. (see screenshots below)


3 The output will now report information about what woke the system from the last sleep transition.

A "USB Controller" can be for a device (ex: wireless mouse) connected to the USB port.

1 Open Event Viewer (eventvwr.msc).

2 Perform the following steps in the left pane of Event Viewer: (see screenshot below)

1. Expand open Windows Logs.
2. Click on System to open it in the middle pane.
3. Right click on System, and click/tap on Filter Current Log.

3 Check Kernel-Power and Power-Troubleshooter in the Event sources drop menu. (see screenshots below)


4 Click/tap on an empty area in the "Filter Current Log" dialog to close the drop menu, and click/tap on OK. (see screenshot below)


5 You can now click/tap on an event log in the middle pane of Event Viewer to see its wake source. (see screenshots below)

Kernel-Power logs with Event ID 507 can help reveal if a Modern Standby device may have woken from Connected Standby.

Power-Troubleshooter logs can help ID wake sources like devices or timers.

That's it,
