Running latest stable KDE (Minimal) at the time.
Almost killed it when, unbeknownst to me, one of my machines spat a beep sequence (which I though was somebody's retro ringtone) right before I placed it in its bag.
The laptop became so hot I wouldn't touch it. Fan on high, battery died, and some 12 hours later it booted just fine. Has happened 3 times, but not once in the last week.
In order to flex its warranty I need help identifying the cause.
Only took place during shutdown.

fan on high indefinitely.
