Completely dead MacBook Pro, won't turn on.
I was using this MacBook Pro. I bought it over a year ago (so no warranty anymore) at an Apple store here in South America. (EMC 2554, late 2012)
I turned it off, everything seemed normal, but the next morning it wouldn't turn on again. It won't even start up: absolutely no sound, as if it was completely dead.
I checked the battery indicator and it was completely charged. I opened it up and disconnected the battery, plugged in the MagSafe charger, and there was still no response. I plugged the battery back in and no response. Plugged in the charger and connected the battery and no response.
I took out the hard drive and all my info was there; it would mount on a different MacBook Pro with no problem, and luckily I got all my files backed up.
So I know the hard drive is not the problem. The fan won't even move when trying to turn it on.
I tried taking out the RAM, one by one, no RAM at all, switching them from slot to slot: no response.
Tried out all of the key combinations on the keyboard as well... still nothing.
I don't know what else to try. I read somewhere that the on/off button is connected to the ribbon cable from the keyboard. I checked, and it is plugged in correctly to the logic board. I'm afraid my logic board is dead, but after only a little more than a year????
Thanks for your help.
