Powerbook G4 Dies when unplug AC Adapter Even with fully charged battery

Powerbook G4 dies when running and unplug AC adapter even though have new battery and shows fully 100% charged. Also when shutdown, won't fully start without AC adapter being plugged in. When in sleep mode then can unplug power adapter and be able to wake and run on battery. Have tried resetting power management unit with no success

Hi, Alan, and welcome to Apple Discussions. Some questions for you:
What does System Profiler have to say about your fully-charged new battery's full charge capacity and current capacity?
Have you tested your internal backup battery?
How long can you ordinarily run the Powerbook on a full battery charge, if you unplug the adapter while it's sleeping?
Have you tested the Powerbook using a different, known-good AC adapter to see whether that makes any difference in the PB's behavior when you unplug it?
Is your adapter's plug deformed in any way?
Is the DC-In port on the Powerbook wobbly, i.e. does it move noticeably if you gently push sideways or up and down on the adapter plug when it's connected to the port?

    I upgraded my macbook pro from OS Lion to OS Mavericks. When unplugged, it heats up exceedingly and the battery life is extremely short. What to do?

    Installation of the new OSX is very heavy hdd load, in addition spotlight reindexes all the files on your computer - it may be a few hours. If in the future will be the same macbook hot, you should contact your nearest Apple Authorized Service Provider.
    May be required to clean notebook cooling system.
    You can also install any monitoring utility sensors to your mac  such as Hardware Monitor  and look at the value of the temperature sensors.

  • Battery died, wont hold a charge, just died.  Fully charged battery dies in approx 2 hours.  Is it battery gone bad. Or something causing battery to use excessive amount of energy.  Do you lose data if battery goes out?

    Battery died, wont hold a charge.  After fully charging battery, battery loses all power in 2 hours. Is this indicative of a battery gone bad or something else?  Will I lose data if battery completely dies?

    Hi, thanks for the reply.
    Yes I have done the reset-didn't work.
    Yeh, the calibration was done so the phone turned off, then plugged back in to charge back to 100%!
    The iphone4s was connected to the charger outlet, the second I unplugged the phone the battery percentage went from 100% to 98%.
    AS we speak my phone is now on 100%, after 10 mins usage and 33 minutes standby. This just doesn't correlate with the decrease in battery life associated with every other number (e.g 99,98,97%) apart from when it is on 100%.

  • Ipad shuts off and restarts after 3 to 4 minutes even with a full battery.

    My Ipad will shut off after 3 to 4 minutes even with a full battery and whether it is being used or not. then it will power up again on its own. This also occurs when the charger is connected and when I have it connected to my computer.

    First try to Reset all settings if this does not fix the issue - No data Loss

  • M9 Very Slow Charging Even With Quick Charge 2.0 Chargers

    I have a continuing problem with very slow charging even with Quick Charge 2.0 chargers. For example last night I had the M9 plugged into a fast charger for over 12 hrs and it went from 5% battery to 87%.   I checked  the Settings - Battery usage history - and it displays "NO APPLICATIONS FOUND" - very strange...
    Something is very wrong. I have multiple 2 amp and quick chargers all with poor charging times. I have tried each of these:
    https://www.amazon.com/gp/product/B00FW1GE9S/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1[/

    https://www.amazon.com/gp/product/B00HP0FOCM/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1[/
    The Ampere app displays varying charger power from 15 mA to 880 mA so I don't think it is accurate.
    Testing with multiple chargers point to the problem in the M9. This is maddening. Seriously considering returning the M9.
    Any feedback?

  • The fully charged battery symbol shows up (a plug instead of a lightning bolt) when it's actually not fully charged! It also stops charging!

    Did you already try to set it up "as new device" How to back up your data and set up as a new device
    If this does not work, try again, this time without using the latest backup, in case it contains corrupt data, causing your problems.

  • Powerbook Shuts Down When Unplugged

    My Powerbook shuts down when I unplug my notebook. It won't power back on unless I plug it back in. The battery is brand new from Apple (part of the battery replacement program) It first happened a month ago while using the notebook on battery for 20 minutes, it shut off. I was able to power it back on with the batttery but HAD TO RESET THE CLOCK and the iWeb document I had opened wasn't saved.
    Now, when I unplug the notebook, it shuts off and won't power back on unless plugged back in and I still have to reset the clock.
    Even though the battery is somewhat new, I'm confused because the notebook has to have the battery reset when the notebook turns off when removed from the power adapter.
    Any answers?

    try running it with the battery removed completely.
    if it runs ok, could be bad battery.
    if possible, try your battery on another machine and different battery on your machine.
    if different battery does not work on your machine, it could be hardware problem with PowerBook.

  • Powerbook takes 5 or 6 attempts to power up even with AC only (battery out)

    Hey folks- I have read up on this extensively but wonder if the info is more uptodate now (as I have been reading about this from about October last year!) and if anyone can get their head around this.
    Powerbook G4 1.5GHz with 1GB RAM Aluminum 15" with the replacement (recall replacement) battery from a year and a half ago.
    Powerbook was out of action for about a month (I got a replacement MacBook Pro) and was put back into action about Christmas.
    Then it took a charge of half an hour before it would start up. So a drained battery was bad news as it took a long time on AC to even allow a start up.
    Worked fine since then with pretty much weekly use, mostly on AC but also using the battery which performed reasonably despite high use of bluetooth and internet. A couple of times a long "recharge" had to be performed to start it up again if it had gone to sleep on low battery.
    Today it also behaved as though it was going to do what it normally does and take a while on charge before it will start up. Started up pretty much immediately though. Worked fine until the lid was shut, the laptop was unplugged and then it was replugged and lid was opened. Dead. Totally. No amber light beyond about a minute or so.
    End result was that I attempted to charge it this morning, watched the light go amber and it only went to green after 10 minutes or more. No start up possible.
    I removed the battery and tried to start it and hey presto- it worked.
    Works fine if started with no battery installed.
    Or so I thought- I even managed to replace the battery and see that it has had a good number of cycles (263) and is definitely not charging.
    So- I realise that it is probably a dead battery, right? Possibly because it is anyway worn out and maybe also because the Powerbook has recently been updated to Leopard (June time). So, to win some time and to be able to restart the computer when we unplug it I thought we'd at least do the PMU and PRAM etc resets...
    Shut down the computer, pressed the various keys for the PRAM reset and got the digital beep.
    Tried to restart the computer with the PRAM combo and nothing.
    Dead. COMPLETELY. Now wouldn't start up even with the battery removed!! Unhooked battery a couple of times, replugged charger and nothing. Left it for a time in case the battery was charging on the amber light (maybe that first reset had done enough?) and still nothing.
    Fiddled and used bad language.
    Turned the Powerbook over and pressed the battery button a couple of times. Interestingly it flashes on the first light when pressed (but doesn't cycle as it ought to if charging).
    Powerbook started up with battery in and AC connected.
    I no longer understand ANYTHING.
    First it wouldn't start up, then only with battery removed, then not at all, then only with battery in place...
    Help, I am going mad.
    Please? Oh- and since I believe I am having to buy a new battery, where? Apple don't seem to have any but am I wrong? Generic or Apple? What is the consensus? OR have we got a bigger problem?! IO board?! Oh NOOOOOO!

    Oh you CLEVER person you! You know I plum-forgot to mention that on it finally/occasionally starting up it has to always have the time/date reset and also the passcode for the wireless internet re-entered.
    Which I KNOW is a defective PRAM battery from the ancient Wallstreet which had one go on it with similar results (of course it was not also wireless) but assumed that it might have been a board go as a result of the aging battery.
    So- took it to our local Apple repairer and they would like to charge me £55 for the estimate and THEN for labour and parts as well! Used to be that we were looking at the estimate/check up being offset against the resulting pair (basically- they had the thing open and diagnosing the fault is part of a repair. Just if you chose NOT to go through with a repair you'd be charged for an estimate)...
    Was told it was either the logic board or the powerboard. Suspect though that the battery option is one which needs investigating FIRST and will power the laptop non-stop for 24 or so hours minus battery to see if that is enough to spark a start up.
    They did try another battery, no go. Tried another powerlead- no difference.
    COULD be that the defective PRAM battery has caused wider defects and that we are looking at replacing a few things but cheaper options first as spending over £200 is not going to make this machine very worth it as it is ancient and might not last all THAT much longer.

  • Laptop won't power up with AC adapter and won't charge battery

    Here is the thing.
    1) the laptop doesn't power on without a battery when directly connected to ac adapter.
    2) the light which would indicate that the laptop is plugged into the ac adapter is not on when the ac adapter is plugged in.
    3) the battery charge light is also not on, which would indicate the battery is being charged.
    The battery does not charge... Laptop turns on the battery backup mode, but not on ac adapter connection. I tried connecting the battery to another compatible hp laptop (both my laptop and the other test device support same battery models). It was charging fine on that laptop. And when switched it back into my laptop, laptop was running fine, but it does not charge in my laptop. But ac adapter is fine too. So whats the issue? And what can I do to get it sorted?
    My laptop is not on warranty anymore. But i replaced battery 4 months back, so its not a fault with battery or the ac adapter.
    The AC adapter is fine, tested with other laptop.
    The battery is also new and works fine

    Hi  ,
    Thank you for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP Pavilion g6-2004tx Notebook and issues with the battery not charging. Here is a link to calibrate and test the Battery. Calibration should eliminate this issue. Plug the power adapter directly into a functioning wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.HP Battery Check in HP System Diagnostics for Windows 8, would give you details of charging and discharging.Testing and Calibrating the battery using HP System Diagnostics in Windows 8. At the starting of the Notebook, Press F2 to select F2 System Diagnostics. Then choose Component Tests, then battery. If the battery was purchased from HP it could be in warranty. Here is a link to check. If purchased from another source you would have to contact them. Hope this helps. Thanks.

  • MacBook won't turn on even though fully charged

    i have a 13inch MacBook pro that I bought in September 2011. It has been on my desk for a couple of days whilst I was away and when I came to turn it on it wouldn't. I have fully charged it (the lights on the side say so anyway) and the charger seems to be working. the sleep light at the front is flashing once every now and then, I've also tried a different plug adapter for my charger and tried a few different sockets in my house.
    Any help or suggestions would be great! I rely on my MacBook to do my illustrations so it's important! Thanks

    So did resetting the SMC as griff w suggested help?
    "the sleep light at the front is flashing once every now and then"
    That's probably an SMC issue. Try forcing it to shut down. Hold the power button down for 15 seconds until you hear the computer shut down. Then reset SMC and restart.

  • My macbook pro shuts down when I turn it on, its fully charged but shuts down automatically when I turn it on, how do I solve this?

    I have the older 2008 version of the Macbook Pro and since Friday when I closed it and opend it again the screen wouldn't come back on and I'd have to press down the power button and restart the machine again completely. Then when I turned it on it would sound like its powering up but after three seconds it would make the bleeping sound and shut down again, its fully charged and I have taken the battery out and put it back in but nothing is changing, is there a way to solve this problem?

    Check this article http://support.apple.com/kb/HT1547 and this one http://support.apple.com/kb/HT2341?viewlocale=en_US
    If it sounds like a RAM issue it could be one of the RAM chips has failed. You could try removing the RAM one at a time and see if it starts with one still installed.

  • My iphone 5 turns itself off even with full charge

    My iPhone 5 turns itself off even with a full charge. Any help would be appreciated.

    That's a very strange issue, but at the moment it could be software or hardware - the only way to find out is by restoring the iPhone.
    http://support.apple.com/kb/HT4137 has all the information you need to backup and restore the iPhone.
    If it's a software issue, it'll be completely fixed by restoring the iPhone!
    If it's hardware, the same thing will still happen even after restoring, and you'll want to get the iPhone serviced.

  • Nomad MuVo will not power on even with a new battery. USB works fine, just No Green

    It was working fine. I didn't use it for a couple of weeks and thought the battery was dead. But it will not even come on with a new battery. Any suggestions?

    Since it connects properly to the pc, I suggest loading the latest firmware into it.

    Make sure that is the correct firmware for your exact Muvo model. If not, then choose the proper one.
