MBP charges, but won't power on
I recently bought a MBP (13" mid 2012 A1278) from an acquaintance and I'd like to see if I can't get it working. She says she thinks she shorted the logic board when attempting to clean the fan. She said she forgot to take out the battery. I'm guessing when she went to pull out the fan something happened. There's no obvious damage to the board, though. I'll be getting a multimeter this week to see if I can't find out if a particular component is bad.
When connected to an original 60W charger, the light turns orange upon connection, and then green. The front power light does nothing. The charge indicator lights show 5/8 green. I've tried every relevant button combination to power on the device. I've reseat the (OEM) RAM, and tried just one stick. I've reset the SMC. I've tried plugging in the charger with the battery disconnected - still no power. I've tried shorting the power pads - nothing. I've also tried shorting pin #5 to ground. I've got an 85W charger coming in tomorrow that I'll try out, too.
Any other suggestions would be appreciated. If anyone has a decent idea of where to start checking connections on the board, that would also be greatly appreciated!
Is this a good question?
