Kernel-Power 41 records an unclean shutdown. It does not by itself show that the power supply failed. The event fields and nearby records give the next clue.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
What the code means
Kernel-Power 41 records an unclean shutdown. It does not by itself show that the power supply failed. The event fields and nearby records give the next clue.
Evidence that helps
Open the System log, verify the provider is Microsoft-Windows-Kernel-Power, and record BugcheckCode. Convert it from decimal only if the field is actually BugcheckCode. Compare nearby events and the crash timing.
Avoid a false diagnosis
A zero BugcheckCode does not establish a healthy PC. Do not replace hardware based on this event alone.
Check the exact Windows build and the screen where the error appeared before applying a repair.
Keep track of your checks
