Replaced MagSafe board, computer won't power on. Suggestions?
My late 2008-early 2009 MacBook Pro was not receiving a charge from my 85w power adaptor (green LED or faint LED), but would start charging eventually after reconnecting it several times. After looking into it, it made sense that the MagSafe board needed to be replaced, and so I did. After very carefully doing so and double checking all connections, screws, seating, etc... the MagSafe board and adaptor seem to work and the battery charges properly (as indicated by the LED charge indicator), but the computer will not power on. So here's what I've tried:
-triple and quadruple checking all connections
-SMC reset (disconnect power and battery, hold down power button for ten seconds, reconnect power cord while holding power button for ten more seconds, turn power on normally)
-swapping old MagSafe board back in
-interchanging both RAM chips
-disassembling and cleaning power button
-powering on with and without battery
None of these things have worked, and I'm really hoping that the logic board isn't somehow toast, as that's a pricey replacement.
I should also mention that I haven't had any problems with this computer such as GPU or anything else.
Anyone have any suggestions?
Is this a good question?
