View Full Version : SOS help please. Macbook Pro won't turn on. Blinking Light

Hello to everyone this is my first post here and sadly its about a problem with my macbook pro.
The notebook in question is a 17'' Macbook Pro I bought in September 2008.
I simply closed it (without turning it off, just let it go on sleep) and took it with me as usual and when I tried turning it on again, it would not turn on.

I press the power button and I hear the hard drive/superdrive (not sure which of the two) start up and I see the sleep light turn on but after a few seconds its turns off again. If I hold the power button down for a few seconds the sleep light starts blinking and then the notebook turns off once more. In all cases the screen is black.

I tried everything here Troubleshooting a MacBook, MacBook Air or MacBook Pro that won't turn on (http://support.apple.com/kb/TS1365) and tried removing and re-installing the RAM and nothing changed.
Short of trying to re-install the RAM again I have no idea what to do. I won't be able to visit a Genius until after the 5th so any ideas/suggestions?

Have you tried pluging the power in and leave it for 15min or so then try.

If the sleep LED blinks repeatedly when trying to wake, then there is a fault with the logicboard. It will need to be properly diagnosed by a technician, but I would put money on it requiring a logicboard swap.
