Computer keeps restarting when in sleep. What do I do?

Question

Hi Microsoft Community,I’ve been facing an issue with Windows 11 on my PC, and I’m hoping someone here can help.

When I leave my PC to automatically sleep, I come back only to find that the computer has actually restarted while it was asleep. The computer is still only asleep because a simple movement of the mouse or tap on the keyboard wakes it up, but then I find that everything I was working on is closed and lost or has to be auto-recovered.

Here are a few details:

• OS: Windows 11 Home (latest updates installed)
• Device: Core i9
• BIOS and drivers are up to date to my knowledge
• No major third-party software recently installed besides adobe acrobat.

This issue has been going on for some time but I only recently realized it because I am writing a term paper and keep having to save everything before I leave my computer to sleep now.

I’ve already tried:

• Disabling fast startup
• Running the Power Troubleshooter
• Updating GPU drivers via Device Manager (nothing needed it)

I have also disabled the automatic restart, changed the power options, turning off fast startup, changing the virtual memory settings, and repairing the system to prevent the issue.  

Still no luck. I am currently conducting a clean reboot to see if it is an app doing it. I have the log files from all the crashes that seem to have occurred while the device is asleep, and I also have the minidump files from today at least.

Has anyone experienced this, and is there a known fix or setting I should tweak? Could this be a driver or power management issue?

Thanks in advance for any guidance!

It sounds like you're experiencing unexpected restarts while your computer is supposed to be in sleep mode. Here are some troubleshooting steps you can consider:

1. Check Event Viewer: Look for any relevant logs in the Event Viewer that might indicate what is causing the restart. Specifically, check for Event ID 41, which indicates that the system has rebooted without cleanly shutting down first. If you see Event ID 46, it may suggest a crash dump initialization failure, which could be related to your pagefile configuration.
2. Disable Overclocking: If your system is overclocked, consider disabling this feature to see if it stabilizes the system.
3. Memory Check: Run a memory diagnostic tool to ensure your RAM is functioning correctly. Sometimes, faulty memory can lead to unexpected behavior.
4. Power Supply Check: Ensure that your power supply is adequate for your system's needs. An insufficient power supply can cause restarts.
5. Overheating: Monitor the internal temperatures of your components to ensure they are not overheating, which can cause the system to restart.
6. Automatic Server Recovery (ASR): If your system is a physical machine, check if ASR software is enabled, as it might restart the machine if it becomes unresponsive.
7. Hyper-V Heartbeat Feature: If you are running in a Hyper-V environment, ensure that the heartbeat feature is configured correctly, as it can restart VMs that appear unresponsive.
8. Check for Suspicious Events: Look for any suspicious events in the Application and System logs that occurred before the shutdown time, which might give clues about the issue.
9. Clean Boot: Since you are already conducting a clean reboot, continue with that to identify if any third-party applications are causing the issue.

If the problem persists after these checks, consider restoring your system to a previous state or reinstalling Windows as a last resort.

Hi,

Does this folder exist?:

C:\Windows\Minidump

If so, if there are minidump files in that folder can you upload them to a public folder on OneDrive or similar site and share the link.

You may have to copy the minidump files to another location such as the Desktop prior to uploading.

Hi Anthony,

It looks like your PC is running into a “wake-from-sleep” crash. Even with updated BIOS and drivers, Windows can still have issues resuming from sleep. A few things you can try:

1. Check Event Viewer Look for critical or Kernel-Power errors around the exact time the PC wakes. This often points to the driver or service causing the problem.

2. Disable Wake Timers Go to Power Options → Advanced → “Allow wake timers” → Disable. This stops background tasks from waking the PC unexpectedly.

3. Test with Minimal Startup Use msconfig to disable non-Microsoft services. Sometimes a background app or media-related service interrupts the sleep cycle.

4. Update Chipset / Storage Drivers Manually Windows Update doesn’t always install the latest chipset or NVMe/SATA drivers, and outdated ones can easily cause sleep/wake crashes.

5. Disable Hybrid Sleep On many desktops, turning off hybrid sleep stabilizes wake behavior.

I’ve seen users experience similar issues while running lightweight media apps on Windows—especially those who stream or manage APK-based apps through emulators. I share related troubleshooting tips on my Cinema APK blog, mainly for people who run media apps on PC and face performance or power-state issues.

Thank you. Please update BIOS to version FM - you have FK.

Typically this should sort out the issue.
