A Guide for the Kernel Power 41 Error

/ Shayne Sherman

The kernel power 41 error is a critical system error that can occur when corrupt Windows system files interfere with the normal operations of the computer. It is an indication that something went wrong while trying to shut down or hibernate your PC and can often result in data loss or damage to your hard drive.

The most common cause of this is corrupt Windows driver files or corrupt registry entries, but other hardware-related issues can also be at fault. In most cases, you will see an event ID 41 accompanied by an entry in the System event log saying:

“The system has rebooted without cleanly shutting down first.”

This error code typically appears during shutdown and restart sequences but may also occur while waking from sleep mode.
