Does your Windows 11 PC wake up unexpectedly after you put it to sleep? If so, this may be caused by connected devices, scheduled tasks, or wake timers. Follow these steps introduced in this article to identify the cause and prevent unwanted wake-ups.
Step 1. Identify What Woke Up the PC
- Press Win + X and run Terminal (Admin) as administrator, then run the following command in it:
powercfg /lastwake
- Check the output for the device or source responsible for the last wake-up.
Step 2. Disable Devices to Wake the PC
If a keyboard, mouse, or network adapter is identified as the wake source, open Device Manager and expand the relevant device category.
- Right-click the device identified in the “last wake-up” report and select Properties.
- Under Power Management, uncheck Allow this device to wake the computer.
- Click OK to disable the devices you want to prevent waking up your PC.
Step 3. Check Scheduled Wake Tasks
If no specific device is identified, check whether a scheduled task is waking your PC.
- Run the following command in Terminal (Admin):
powercfg /waketimers
- If a task is identified, press Win + R, enter taskschd.msc, and press Enter.
- Find the corresponding task and open Properties > Conditions.
- Uncheck Wake the computer to run this task if you don’t need it.
- Click OK to save the change.
Step 4. Disable Unnecessary Wake Timers
If you don't want scheduled tasks to wake your computer, you can disable wake timers through
Power Options.
- Open Control Panel > Hardware and Sound > Power Options.
- Select Change plan settings > Change advanced power settings.
- Expand Sleep > Allow wake timers.
- Set the available options to Disable.
Step 5. Verify If the Problem Is Fixed
After applying the relevant changes, put your PC into
Sleep mode and leave it untouched for several minutes. Check whether it wakes up automatically.
Conclusion
A Windows 11 PC that wakes up unexpectedly is often triggered by a connected device or scheduled task. By identifying the wake source and adjusting the relevant settings, you can prevent unwanted wake-ups and keep your computer asleep when needed.
