Hello

This is my first macbook pro repair ! ive see some youtube on that most of these models have an GPU issue and needed to be reballed of reflowed.
First of all iam having trouble to identify the mainboard type.
when i connect the magsafe the green led goes on but no respone form the macbook.

820-2532 as written in second picture near top left corner.
Only the 2011 model 820-2915 has a very high failure rate of GPU. Reflow or reball is a scam.
This 2009 model 820-2532 has a high failure rate of C7771 instead.
These older machines don't turn on automatically when connecting MagSafe, power button must be triggered.

Re: A1286 No power

Forgot to mention when pressing the power button there is no change.
Where can i find C7771 ?

EDit is it this one ? When i measure it iam getting 1,1V

Re: A1286 No power

okay looks like i used the wrong magsafe 60w,
So i got an 85w and the system goes on. Now only strange issue is that the mousepad click does not respond
