Hello, I've got a 2008 MacBook Pro 15" and it just wont start up anymore. Shut it down on Friday evening and it won't start up since. As I write this I realise that it was Friday 13th I switch the power on, you can hear the hard-drive spin, the DVD drive spin, the fans are going, but black screen and no startup chime. Caps lock light won't come on, so I'm wondering if the keyboard is the problem? I tried inserting the OSX DVD, and restarting, but no joy, and now the DVD won't eject. Tried resetting the SMC as per here, but again no joy. This time last year I replaced the original 200GB disk with a 500GB hybrid drive, but that's been working fine. Until now. Is there anything else I should try before getting the screwdrivers out?
