Magsafe light turns on, fan runs, no power.
My macbook suddenly didn't turn on one day. Prior to this I had run a system check and saw that my battery wasn't doing good, so when it didn't turn on I bought a replacement battery.
It still won't turn on though. I look around inside it with it plugged in and unplugged. The Magsafe light is on when I plug it in and the fan runs, but the SSD gets pretty warm quickly. Decided to take that out to see if it would be with the question mark folder, but no such luck. I'm out of ideas now besides replacing the logic board, I/O board and everything else piece by piece until it works.
I'd very much appreciate if someone could help me with this. I did try a keyboard combo I saw somewhere of holding Ctrl, Option, left-shift and the power button for ten seconds and everytime I do that the Magesafe light goes green for a short period, then back to amber. Not sure what that means, but I know the keyboard still works.
Thank you to anyone who can help.
