    Hi Guys,

    I have a 17" powerbook with a 1.33ghz processor, 1gb of ram and a 80gb HD. It all works fine until It has to push itself slightly - for instance when importing a cd into itunes or opening a very large photoshop file. All of a sudden it will just go sleep and it is impossible to wake it back up - even when on 99% battery.

    I have to take out the battery and wait for the sleep led to go off after about 5 minutes, before I can turn it back on!

    Whats up with it? Can I fix this?

    Thanks in advance.

    G

    Oh yes, and when I start it back up again it says the battery has 0% !?

    Yet the last time it happened it was 78% charged when it went to sleep

    I match you a PRAM reset and raise you a PMU reset + battery calibration. Oh, and re-seat the battery to make sure the connections aren't loose. :)

    hehe. Thanks guys.

    I reset the PRAM thismorning before coming to work, so I'm yet to know if it has fixed the problem. I shall find out tonight - and if its still sleeping i'll try the other stuff.

    Thank you.

    Ok its still doing it after resetting the PRAM.

    Im going tot ry recalibrating the battery and resetting the PMU.

    Do you think it could possibly be a dodgy battery/battery connection? It just seems odd that after it "crashes" the battery is completely empty (0%)

    Its really quite anoying :(

    Edit- What does this mean?

    " Warning: Resetting the Power Manager on any PowerBook or iBook will permanently remove a RAM disk, if present, and all of its contents."

    Excuse my ignorance :)

    Don't worry about that. RAM disks were used pre-OSX and aren't relevant anymore. :)

    I had that problem. I had faulty temp sensors that thought my PB was overheating (but it really wasn't), thus, it was going into sleep to protect itself. I had to send it out to Apple for a new logic board, it's been fixed ever since.

    Looks like Ive sorted out the problem!

    I reset the PRAM originally but it still went to sleep once after that. Then I calibrated the battery and turned off automatic sleep completely in energy saver and it is working perfectly - all the time.

    : )

    logic board?

    hi, guys,

    i have the same problem too. since i got that kind of problem, i brought it to technical support on campus. they sent my computer to apple store to fix it.
    they said the logic board and keyboard were wrong, and i paied 461 dollars for it.

    Then, 10 days later, it came back to my hands.
    then, i happily used G4 for a hour. BUT i still had the same problem !!!

    i madly went back to tech service and asked a manager.

    then, he said, "we replace the whole stuff inside your computer. probably, your softwares are bad.." What are you talking about? if my sofewares are wrong, how come i had to pay 461 dollars in the frist place!

    i gotta go to tech service to get the money back !:mad:

    Have you tried simply turning off automatic sleep? Sounds silly but it worked for me.
