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.
You can use the powercfg.exe tool to control power schemes (also named power plans) to use the available sleep states, to control the power states of individual devices, and to analyze the system for common energy-efficiency and battery-life problems.
This topic describes the scenarios in which the devices in this PC must be able to wake the processor.
During modern standby, Windows periodically transitions the SoC platform from idle mode to active mode to perform value-adding tasks.
Open Windows Terminal, and select either Windows PowerShell or Command Prompt.
Copy and paste the command below into Windows Terminal, and press Enter. (see screenshots below)
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.
Open Event Viewer (eventvwr.msc).
Perform the following steps in the left pane of Event Viewer: (see screenshot below)

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)
