Nice. I might copy your idea.

Do a BIOS recovery using the jumper. You’ll have to go to download the recovery BIOS from Intel.

Edit: didn’t read the full post. You can turn off the other LED in the bios.Youll need a display to know what’s going on and to debug. If no storage is present, it usually boots to PXE boot or a screen that says no boot device found.

100% disagree that “most people” need more than a brick.

Windows is never responsible for this. It is errors in the EC code or BIOS wake timers. When you click shutdown, the system is powered off. Windows hands off execution to Bios code for shutdown after the cycling dots saying “shutdown”.
