I had a program running last night and when I woke up this morning my computer wasn't on. I attempted to turn it on and nothing happened. I know this is a vague question, but what could be the issue? Thanks for your help.

MacBook Pro, Mac OS X (10.4.1)

    Hi t,

    Is the power adapter plugged in to provide power?
  • tdubbs26 Level 1 Level 1 (10 points)
    It doesn't seem to recognize it. The lights (neither green nor orange) don't come on. The battery is full though. The computer just won't turn on.

    Try an SMC Reset.
  • tdubbs26 Level 1 Level 1 (10 points)
    Unfortunately, that didn't do anything.
  • tjk Level 7 Level 7 (24,165 points)
    Exactly what happens after you push the power button? Is there any activity whatsoever?
  • tdubbs26 Level 1 Level 1 (10 points)
    Nope. Nothing at all.

    Then, if you know it's getting power (batt and/or power adapter), there isn't much to do but bring it to the "genius" bar or an AASP. Earlier you said the batt has a full charge. How do you know that?
  • tdubbs26 Level 1 Level 1 (10 points)
    Because all the green lights on the battery light up.

    I first thought that the MagSafe board could be shot but I'm thinking it's more serious since the computer itself won't even turn on with a charged battery.

    Try the usual.

    Boot safe mode...

    then try single user mode (verbose)

    reset pram (hold down commandoption+pr) while booting

    target disk mode work?
  • tdubbs26 Level 1 Level 1 (10 points)
    The problem is that I can't even attempt those things because the computer won't turn on. Period. Nothing.

    I'm curious if someone could tell me that if my MagSafe board is dead could that cause my MacBook Pro to become unresponsive? I'm thinking that it's both my Logic board and my MagSafe board. Thanks.

    I've never run across that before and don't know the answer to that question, but if the left I/O board can indeed cause there to be absolutely no signs of life even with a fully charged battery, then it could also be just the cable between that board and the LB. Another potential cause of these symptoms is a faulty power button, which requires replacing the top case. Given that as a possibility, try "massaging" the power button, especially around the edges. I've never had one apart, but with power buttons on other electronics/electrical equipment that has sometimes yielded results.

    Depending on the cost, it might be worth your while to find a place that will test the components, not play trial and error replacement.

    Good idea.  Maybe a short inside the machine as well?  Sometimes the power supply will not operate as a protection for a shorted peice of hardware i nthe machine.  Also, you could just take it apart and test the power lines with a voltmeter to see if they are working and in spec.

    Be carefule though!
