MBP Unibody won't power on
My old 15" MacBook Pro Unibody (2.4 GHz late 2008 A1286) won’t power on.
I’vet tried the various reset PRAM / SMC options, removing battery etc.
I know the charger is working. The machine won’t run when it’s connected to charger with the battery removed. So I’m pretty sure it’s a hardware issue.
I have a second machine to use for spares - which I can use parts from to repair the first machine.
So my question is where to begin. Replace DC in board? Logicboard ? Other parts? Any advice on diagnostics, most likely source of problem and best order to replace parts by trial and error would be v welcome.
