The computer will shut down and restart on its own. After restarting, Kernel-Power 41 (63) will be referenced as the critical event ID in the Windows Event Viewer. This event ID means the computer did not fully shut down or did not successfully transition out of sleep mode.


Running programs that place heavy demands on system resources can result in a computer crash and kernel power error 41. Another cause is problems with the system's sleep or hibernation modes. Sudden power loss or a faulty battery can also cause kernel power errors.


Download the most current updates for your system from Microsoft. Using the Microsoft Fix It troubleshooter can help diagnose the cause of the problem. If the problem began suddenly, remove any recently installed programs.
