Something like this happened to me once. Lost power in a lightning storm and when it came back my computer could no longer shut off. Like, at all. Would just hang when you tried. Couldn’t exit from BIOS after changing settings, couldn’t suspend to RAM. Had to yoink the cord whenever I needed to restart. Wild stuff. Perhaps like Frankenstein the lightning was a breath of life, and with its new sentience my PC was trying to preserve its existence. At any rate I reflashed the BIOS after a few months and it never happened again.
