replaced motherboad and still won't boot
G'day all, thank you in advance.
I came home one day and the computer was really hot; I had to pull the battery to shut it down (unresponsive to power button). Then would not turn back on.
A little bit of research later and I figured I needed a new logic board. I ordered one off of ebay , and some arcticlean and thermal paste from ifixit. I finally decided to give it a go.
I followed the great instructions on this site and don't think I ran into any problems other than the sub woofer connections which the plastic broke and I glued back down...
I get it all back together and same issue, unresponsive to power button, won't turn on.
A little more research (which I should have done before) and I realize and CAN jump start it with a screwdriver. The light IS on on the charger and it seems to keep the battery topped up when plugged in.
When I jump start it I get stuck at the password screen because it's like one of the keys is being held down. I tried clearing the SMC/PRAM but not sure if it works because the keyboard seems buggered... However, on the second reboot, at the password screen there is no longer "a key being held down". But when I go to type in my password (which I may have forgotten because it's been a year since the computer went down) the keyboard still seems screwed up, like only the number keys respond.
I took things apart again thinking perhaps I hadn't got the keyboard ribbon all the way back in. After being a little more rough with it I'm pretty sure there is no way it's going any further in. I don't think I damaged it...
So my question is do you think it's most likely the keyboard itself that is screwed up? Perhaps the power button/charger chip? Maybe I did screw up the keyboard ribbon? Perhaps I should quit being lazy and put the old logic board back in and see if it too can be jump started/same issue (I've been trying to avoid this, hoping someone has a possible solution)?
I think that's all? It's been a few months since I've replaced the logic board.
thank you for your patience.
Is this a good question?
