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.
