2 Random shutdown, with or without battery
Hi,
I bought cheap an old MBA 11’. The laptop was shutting down randomly.
I cleaned up the dust from the fan and the board, removed the heatsink to change the thermal paste (or the leftover gunk…).
I monitor the temperature constantly and the shutdown are not related to overheating. I had shutdowns at 50°C.
Thinking it could be power related (the battery has 995 cycles) I tried to pull the battery from the device and ran it without, shutdown again.
Did I miss something? Or is it simply a dead logic board that I won’t be able to repair.
Это хороший вопрос?

Did you review the crash logs to see if something got reported.

Yes. Nothing in the crash log.
Did a fresh Catalina install when I got the machine. Took a couple tries before I could successfully finish the installation.
The shutdown is nearly instantaneous. So I doubt anything could be reported .
It looks like power was switched off. And usually the laptop needs a couple minutes to start again unless I reset the SMC
