Fan spins for roughly 5 seconds and keeps restarting. Short somewhere?
Hi guys,
I have a MacBook mid 2012 logic board 820-3024
The fan spins when the power adapter is connected then keeps restarting the fan spin process after about 5-6 seconds. I’m convinced there is a short some where; I have the schematic heat gun multi meter iron etc so am ready to start diagnosing & fixing it.
Anybody come across this issue ?
Where abouts should I start measuring resistance values etc.
I know old turkey is good with this stuff. Any help will be greatly appreciated :)
I might even buy you a beer !! Haha
PS - MAGSAFE ADAPTER LIGHT STAYS GREEN
Update (08/15/2021)
Board is 820-3023-A… my bad
Ist dies eine gute Frage?
What happens when you remove the SSD?
Follow this guide MacBook Air 11" Mitte 2011 SSD austauschen to take it out. Does it now boot up with a flashing Question Mark in a folder icon?

Hi mate,
Removed all peripherals mousepad speakers ssd etc ..
I/O board is good. Backlight fuse good.
It’s a power issue for sure.
Thank you for your reply :)
