Windows 10: Sudden shutdown when in battery mode

My HP laptop is fine when in AC mode. When in battery mode, the laptop will unexpectedly shut down, and this can happen after various time lengths. Battery check reveals no problem. Battery is usually 80 to high 90@s %. All drivers checked and ok. BIOS checked and ok.

Computer management logs always show the same event. Critical - Kernel Power - Event ID 41 - Task Category 63. The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed or lost power unexpectedly.

I have tried to research this, but no clean answer. Other than this does seem to be a problem with HP. Any new perspective would be appreciated.

Problem appears worse since latest 1909 update.



Many thanks

PC is Suffering Unexpected Shutdowns

Most important detail to me would be whether these shutdowns are sudden, in which case it's likely a short or PSU issue (capacitor aging maybe?) or graceful windows style shutdowns, which suggests software interference.

It could also be overheating components if it's a sudden shutdown. What are your thermals like?
