MacBook turning on, power indicator on, fan spins up, shuts down
I have a 2011 17” MacBook Pro which I have attempted to fix the graphics on, first time worked. The second time I tried, I did the usual oven reflow, reassembled the computer and all I got was the optical drive and fans spinning up and the power indicator immediately followed by a shutdown. I have tried different RAM arrangements with different modules and the is no directly visible damage to the board.
Is dit een goede vraag?
