MacBook mid 2012 fan spin sleep stays on
Hi,
Just a issue with my macbook mid 2012
no water damaged, no corrosion very clean
Sometimes it turns on and it works but this could be about 100 attempts.
Normally when i turn on my macbook fan spin normal speed and white sleep stays on
no external output
when i take out ram it beeps so it knows when there is no ram
i have tried the following
smc ,pram reset
changed ram with working ram,changed battery,changed charger
unplug all connections apart from lcd
Does anybody have any ideas( Looks like Logic board)
