Cleaning the motherboard did not help. In fact, it now doesn't boot at all. The corrosion must have damaged some motherboard components or ate all the way through a connection.

Replacement motherboard ordered. Got an i7 instead of the Intel i5 that was in it.

A customer's laptop was crashing, abruptly turning off, while I was trying to check it over and apply updates. No crash recent crash dumps. That indicates it may be something physical, possibly overheating.

I took the bottom cover off, then removed the CPU heat sink. Was going to apply fresh thermal paste when I noticed corrosion on the motherboard. I examined the bottom cover again and noticed some discoloration around the air vent that lines up right with the corrosion. I think something may have dripped through that vent while the laptop was upside down.

I will clean that up with rubbing alcohol and see if it works better after that.
