Was using a rarely used MBP to restore my Mothers iPhone today, the iPhone failed to restore and went in to DFU mode. iTunes then sat waiting for the iPhone, so I thought best to reboot the MBP and start fresh. White light came on, fans and HDD started spinning, nothing else. It's a 2008 A1260 2.5Ghz MBP, used as an iTunes server and nothing else. Sleeps and wakes, never turned off, never did anything strenuous, didn't get overly hot. Tried PRAM, SMC, taking RAM out, different RAM, booting from a disc (via USB, internal one died and think I threw it out) Any ideas? Despite it being an 8600M model, I don't think it's an issue with that. Seems like something failed that's only used in boot up, which is why it worked fine until it tried to reboot itself.
