No answer, but likely contributing semi-conductor EE semi-conductor thermal engineering / humidity limitations.
First, water conducts electricity.
Second, I killed the wife's Zenbook.
She still doesn't know, but I suspect I know why its power dead, quite possibly a root cause of many other Zenbook fails.
I downloaded a game for my kid. It's highly graphic-CPU intensive, as the fan is on in <15 minutes and the Z'book gets hot. Every 30 min, I opted to unplug, as Z'book fan is working overtime to try to cool a VERY hot left keyboard corner / power supply - video processor.
I don't believe the Zenbook was meant for intensive and sustained compute-intensive video graphics.
It's either going to over-heat and have processor fail for semi-conductor thermal limitations, or if cooled too quickly, when shut off, absorb and condense resident environmental humidity to short out critical elements lending to grant of main and/or battery energy supply.
Still looking for means to reset what I see as a now dried out short circuit, on the premise I didn't actually damage a what should have been moisture protected circuit for its heat profile.....
Hopefully I'll learn an answer to share.
