System unable to shutdown after update
4.5
The PC hangs on the "Shutting down" screen or restarts instead of turning off.
Symptoms
- Infinite spinning circle
- Fans stay on after screen goes black
- PC reboots on shutdown
Possible Causes
- Update process stuck
- Driver power state failure
- Fast Startup conflict
Step-by-Step Fix
1
Force Shutdown
Hold the physical power button for 10 seconds to force a hard power off.
2
Disable Fast Startup
Power Options > Choose what power buttons do > Uncheck "Turn on fast startup".
3
Check for Pending Updates
Ensure the update actually finished; sometimes it needs one more reboot.
When to See a Technician
A "Restart" loop is often caused by the "Automatically restart on system failure" setting.
