    i put my MBP (intel santa-rosa late 2007/early 2008) to sleep by closing the lid.
    i went back and opened the lid and got nothing apart from hearing the optical drive make its usual noise.

    so i killed the power and tried to boot up normally... again nothing other than optical drive noise and the white light is on at the front of the MBP.

    have tried resetting the SMC - still nothing
    tried CMD-OPT-P-R during boot - still nothing.
    tried swapping out RAM - still nothing.

    i get no bong, no display at all.
    only indication that MBP is actually getting power is the optical drive noise and the white light. battery also still charges whilst plugged into mains.

    any advise please ?

    You didn't by chance have it plugged into an external monitor when you put it to sleep?

    Can you enter Target Disk Mode, Safe Boot mode, or boot options mode? Do you have another Mac so you can utilize Target Disk Mode?

    Can't access any boot modes. Display is always black (off).

    Just to make sure we are on same page. What procedure or how did you go about resetting the SMC?

    I've now managed to get it to "bong" at startup without the battery installed. But still no video at all.

    And fans are running full speed.

    Take your computer to an Apple Store to see a Genius - you've got a problem with your hardware (probably the logic board or RAM memory).

    Already tried swapping the ram so I know it isn't that.

    Didn't do anything I hadn't tried before.
    Just tried resetting smc for the 10th time.

    It sounds like it is booting as if I press a lot if keys at once it makes that little noise it to tell you.
    Still absolutely nothing in screen though.

    The MagSafe is showing a green light but the battery is only 20% charged and the fans are running full.

    I don't have an external monitor, only LCD tv and I cant connect it to that just now.

    Yeah you have a bad logic board. If youre in warranty, get down to the Apple store to get your computer repaired

    I'm not in warranty but is this covered by the extended 3 year nvidia failure warranty?

    it's probably not your graphics card thats causing trouble *unfortunately*

    to repair a logic board on an out-of-warranty MacBook Pro often costs around $700 or more

    Sorry for hijacking, but can you explain this further because this may have been my scenario the other day, and not gpu failure, or was it? I had an external monitor attached and closed the lid. I remember pulling the dvi cable for the external out after the mbp went to sleep. The next morning I open the lid and the display was completely black, including the backlight. The only solution was to hard reset.

    My initial thoughts was the onset of the now notorious 8600M GT failure since I have had my logic board replaced one year ago under warranty for that very same issue. Could this have been something entirely different?
