    have you checked your system preferences on how many minutes before your pb sleeps--it's under energy saver.
     
  3. yes i did, its put to never but then it still sleeps, i tried restarting, rebooting, reinstalling 10.4.7, reseting ram as well, what could possibly be wrong?

    There could be a problem with your sleep sensor where the powerbook "thinks" that the lid is closed.

    When it goes to sleep, can you wake it up again by just hitting a key or do you have to plug it in?
     
  6. sometimes i can wake it up easly, but sometimes no. this has happened for the first time, any advice?

    Maybe you can check some of the ff:

    1. Can your PB battery still hold charge?
    You should have a battery icon somewhere near the upper right of your screen, it should tell you how long you can go with the pb unplugged. If it is too low, say 10% or lower, you may have a faulty battery if you are plugged yet its not charging. You can also check it by pressing the silver button in the battery (bottom of your PB), it should light up 4 green lights to indicate a full charge.

    2. If the battery is full and your PB sleeps still, the sleep sensor maybe malfunctioning. In this case, go to your nearest Apple Center

    But if you still find yourself pulling hair, go to an Apple Center for peace of mind.

  8. thank you, this happens only rear times. anyone have an idea on how to reset the sleep mode?? yeah i guess this is sleep mulfuctioning, cause i left my powerbook turned on when i left and it drained it battery and when i got home, it was off, this was when it started to happen, any advice? i don't think they have an apple center here in the middle east, this help would mean so much to me and will be very much appreciated, thank you
     
  9. hi randytamayo, do you think if i reformat my powerbook this will solve the problem? will it be ok and goes back to normal? or is it in the hardware problem?

    Try disk utility first.. If can't then reformat it again.

    Thanks

    patrix, i was wondering if you were able to solve the sleep problem with your powerbook? my 15" PB has been having the same problem the last couple of days (sleeping randomly and often). i've tried everything from resetting the PMU, zapping pram, repairing permissions and still my powerbook is narcoleptic.

    let me know what you have done to solve this problem or if any apple service centers have been able to fix it. thanks.

    hi tiongks, sorry to hear you're having the same problem with your pb. is your powerbook still under warranty? best to have it looked at asap. mine started having the sleep problem a few weeks after warranty expired (of course!)

    also, i found that the danny hajicek hack works but only if i don't restart or shut down my powerbook. if i do need to restart for some reason, the sleep problem occurs and i perform the long tedious hack process again.

    seems the problem is more widespread than i thought which is interesting.

    I know this is reviving an old topic but might be helpful for those who still use powerbooks.

    I experienced this with my powerbook... Sleeps automatically and sometimes I can't wake it up. I tried resetting the PMU, zapping the PRAM... Nothing.

    Googling, I found that a lot of people are experiencing this problem. I checked my system log and found out that the sleep was caused by an overtemp or high trackpad temperature detected by the termperature sensor. Following a solution proposed... I think I've solved it - so far hehe

    The solution is probably not for everyone. It involves opening up your powerbook and desoldering the temperature sensor IC to take it out.

    I decided to go with this solution since it seemed to be the only permanent solution (so far) and considering my context (out of warranty, can't even find my receipt, etc.).

    Just sharing :)

    It didn't seem to be too difficult. The only thing that made it "hard" was the temperature sensor's size. Good thing I had a soldering iron I used in my college freshman days haha

    Here's a picture of the temp sensor on a 25 centavo coin. Of course I managed to tear off a couple of the IC's legs in the process hehe
