MacBook Air shutting down randomly on OS install
I have a MacBook Air 11” from 2012.
The laptop boots normal but it always shuts down before finishing the installation. Its never the same time it is shutting down, totally random. Sometimes right away a few seconds after booting sometimes 60% in the install.
I dissasambled the laptop and tried it with no peripherals. Same thing still shutting down.
PCB looks very clean und no signs of liquid damage.
I cleaned of the old thermal paste and put new paste on the CPU. Nothing changed.
I am not sure what i am looking for. Is it some kind of power problem that the pmc has a fault or mire likely to be a sensor issue?
Hopefuly some on can help me. I can provid pictures if needed.
Anyone with a similar problem? And probably a Fix?
Thanks a lot peace üt
I found one component missing!
first question what is it, looks weird and not really part of the schematic.
Is that importent and tthe problem?
Looks a little bit like I ripped it of when i took the motherboard out
Sierra is working on the Macbook now . It is booting fine and most of the time its all good. but still sometimes it rondomly crashes.
I run the apple service diagnostics tests and it seems to be a Memory Ram issue. Does anyone of you know about Ram issues on the Macbook air 2012? What can i do about it?
