Battery never stops charging....

I have a Powerbook I got back in September of last year, and overall I've really enjoyed using it, but I have a somewhat unusual problem. I'm hoping that it's only my impatience and that there isn't really anything to worry about, but let me begin.
I often use my machine while it is plugged into an AC outlet, with the battery installed in the bottom of the machine. Now, after the battery is fully charged, it shouldn't start charging again until the battery percentage drops below %94, according to the user's manual. Also, the light is supposed to change from amber to green and stay that color until the machine begins charging again. However, my machine seems to be in a continuous state of charging, even after I am supposedly charged up to full capacity. This only happens while I am operating the machine on AC power, not when I'm charging the machine with the power off. In fact, right now my batter is supposedly at full capacity, but instead of getting the "plug" battery icon, at the top of my screen I still see the "charge" icon with (calculating) displayed where the time should be. I thought that maybe it was simply finishing its charging for the last little bit, but even if I unplug the power cable and re-plug it, it will switch to the "plug" icon for a second and then resume charging.
To sum up, my machine continues to charge even after it is supposed to stop. I tried the battery updater, but it said that I didn't need the update. If someone could provide me instructions on resetting the PMU, I intend to try that next. Please, anybody else who is having this problem let me know if there is an easy solution. Thanks.
Powerbook G4 15"   Mac OS X (10.4.4)   1.5Ghz, 1GB RAM

Okay, so I misjudged. The machine does recognize the full charge available now. I imagine that there must be some sort of strange interaction involved between the mouse and the rest of the hardware on startup, because it was fine after I booted up with the mouse disconnected. Either that, or it just takes a very long time to charge the last little bit of capacity available to the battery before it's done, and the machine doesn't recognize the battery as full until it's "cycled" and the plug shows green for the first time.

  • X201 Battery Suddenly Stopped Charging

    I'm a new user of the X201.  I was sold on the 'name' and 'reliability'  and 'quality' of the product, the X201, on the design and size and power.  So I paid the premium for this notebook, where I could have easily bought TWO Acers with similar power and storage etc.
    This was in June 2010..
    The battery suddenly stopped charging and status was 'amber' and software says battery is charging... it's not.
    battery condition is all green... good...
    what's happening? 
    Moderator note; post moved to here to start new thread, subject edited

    I am experiencing the same issue with my X201i. It is just weeks old and battery has been used for five cycles.
    Unfortunately it seem to not want to charge the battery anymore, and it stays as 0%. I have been in touch with Lenovo, and they are shipping a new battery that I will try. However, I tried to upgrade form bios 1.14 to latest, but this did also failed because of no charged battery which is required for a upgrade :-(
    Any more updates on this so I can try to get the battery charging again?

  • Battery wont stop charging

    I got my ipod around 5 months ago, but recently the battery wont stop charging. i had my ipod plugged into the wall socket adaptor for around 10 hours, and when i checked it this morning, the charging icon was still filling up, showing that the battery was still not full. its hard to tell how much battery i have right now, casue the indicator is fluctuating between around 75% and 90%. anyone know whats going on? its a 4th gen. ipod mini, BTW.

  • Early MB-A Battery has stopped charging

    G'day All - I have an early MBA that has just stopped charging the battery.
    The adapter still powers the computer and shows the green LED, but it never goes amber now showing the battery being charged. I have changed adapters, reset the SMC and PRAM - all without change.
    If take out the adapter, the computer instantly dies. On restart after sudden death, with the adapter plugged in of course - only way to restart - the computer clock has lost all track of date/time. Interestingly, if I shutdown/restart with the adapter remaining connected throughout, it doesnt lose the date and time. Bizarre!
    CoconutBattery says the battery is in good shape but not charging. It shows 17% and that does not change - I thought it might slowly reduce with some kind of trickle discharge
    AHT doesn't run on this computer.
    Feels like a hardware failure to me - any ideas please?
    Thanks

  • Battery never fully charged

    I got an iPod touch last saturday and i noticed that when chargeing the battery gets to about one thin line away from fully charged and then never finishes charging, but when unplugging it shows a full charge, and sometimes if I plug it back in it'll either go back to a line away from 100% or show the plug symbol (full charge)
    Any ideas?

    i now know about the quick and full charge. Quick charge is now represented as one thin line away from 100%, while full charge (leaving the ipod charging for a bout an hour after you reach the thin line will show the plug symbol).

  • Apple Support: Distressing under performance on simple questions: new iPod Shuffle battery never gets charged.

    New in the mail the other day:  iPod Shuffle.  Works great, except it has never indicated that the battery is charged (orange lamp continuously blinks.)  Should I send it back?  Simple enough question right?
    So I go to the Support site, enter a ticke with my Apple ID and the S/N of my new device, express via choosers that it's a battery issue ... but there is no ability to even say what I did above just now.
    Of the support alternatvies, I schedule a call.  The phone call came over 30 minutes later than was scheduled.   And then!  The operator didn't have the information that I'd taken time to enter in to the webforms -- critically, the S/N, etc.  I expressed a bit of frustration, we ended the call after I'd recited as much as she could take notes for.  Later I get an email from her (bless her spirit!) ... with all of the links I read BEFORE going to effort of filling the support documents out and scheduling the call.
    I'm really wierded out by this.  APPLE COMPUTER -- THIS IS BABY FOOD BASIC CUSTOMER RELATIONSHIP MANAGEMENT!
    So, do I send the little stinker back or just live with having purchased a defective device from a company incapable of supporting it?!!!!

    I don't think it is defective.  The light will ALWAYS blink orange when connected to iTunes, if the shuffle is set to Manually manage music (or Enable disk use).  You can check the setting on the shuffle's Summary screen in iTunes.
    Blinking light - This means DO NOT DISCONNECT.  Eject shuffle before disconnecting.
    Solid light - This means OK TO DISCONNECT.
    A solid green light does mean battery is fully charged, but it will never blink green.  There is an eject button next to the shuffle in iTunes.  When you eject the shuffle and leave it connected to the computer, you should see the light become solid green (if the battery is fully charged).

     Does the laptop work with just the adapter ?
     What happens when you drain the battery to 12% and try charging it, or have you done that already ?

  • Satellite C50-A-1G7 - battery has stopped charging

    My C50 has a battery issue. A few weeks old, it stopped charging. First it started charging (as seen on the windows power icon) slowly until 61% then zipped to 100%. But since then, the computer won't work on battery. The charging light does not come on(, but did so before). For all intends and purposes, it looks as there is no battery present, except that the software (windows and toshiba help stuff) insists there is a fully charged battery present.
    Now, it probably is a faulty battery or connector, but to avoid going to the shop needlessly, I would like to verify if there is a bios update available. Since it is a relatively new, maybe not but the toshiba site is not the most clear. Anyway I couldn't find any bios update on the pages for Satellite C50-A-1G7.
    Currently my bios is 1.20 with EC version 1.00
    tnx

    To be honest I don't think BIOS update can be solution for this. Anyway, you can check which BIOS version is offered on BIOS download page - http://www.toshiba.eu/innovation/download_bios.jsp
    Im afraid you must contact nearest Toshiba service. They have special tools and can check hardware functionality.

  • Can't calibrate because battery never fully charges

    I want to calibrate the battery in my new MacBook.
    According to Apple's instructions, the battery must first be fully charged before you let it drain down for the calibration.
    Problem is, I can never get my battery fully charged. The battery indicator in the menu bar shows it getting up to 99 percent charged, but never 100 percent.
    Any suggestions?

    Try to charge it when the MacBook is off.
    Charge until the magsafe adapter turn green and all 5 led lit green, then turn on your MacBook and start the calibration.
    Hope this help

  • Battery suddenly stopped charging

    I've got an early 2011 MPB (2,8). It went from having a battery that charged up just fine to one that will now only read 0%. I've dug through a lot of forums and done the SMC reset and PRAM reset to no avail. I'm wondering if anyone else has had this problem(?) I'm also wondering if there's anyway to do a reset on the firmware - from what I could glean online some MBPs have the option to restore firmware with a Restore CD, but it doesn't seem there's a version for my model.
    thanks in advance.

  • Battery stopped charging; won't run from battery

    A couple of days ago, my computer stopped running from battery, and stopped charging the battery. I can see that the level is 67%, but that never goes up, and it shuts down if I unplug the power adapter.
    Here is XBattery info:
    Installed: Yes
    Charging: No
    Charger: Yes
    Battery%: 67
    Max. cap: 4.400Ah
    Curr. cap: 2.271Ah
    Charge: 1.534Ah
    Voltage: 11.850V
    Amperage: 0
    Cycles: 680
    Flags: 41000005
    Anyone know how I can fix this?

    I have the same issue with my Powerbook G4 15" Aluminum (battery not charging and clock not retaining date and time). A 3rd party warranty company is trying to say it's the rechargable battery but I think it's something to do wit hthe small battery located on a daughter board on the motherboard. Can anyone verify this or does this sound like a totally different issue?
    The battery was replaced under the recall less than a year ago.
    Thanks,

  • Battery stopped charging when Satellite C connected to the mains

    My battery has stopped charging when I plug my laptop into the mains. It continues to lose battery life until there is zero charge and then shuts down. Only then will it let me re-charge the battery.
    The only other option i seem to have is to switch my computer off, shut down all documents and leave it for 15 minutes before plugging into the mains.
    This is obviously very disruptive! Can anyone help?
    Many thanks
    Marc

    Hi
    Im not quite sure whats wrong with your notebook
    Are you able to use the notebook without plugged in battery but connected to the mains?
    If the AC adaptor is ok, you should be able to use the notebook connected to the mains only
    Lets assume the AC adaptor is ok in such case either the battery or the power supply electronic which is part of the motherboard may malfunction
    Its difficult to say if your battery is faulty this needs to be tested but I think its not worth to purchase a new battery just for testing purposes therefore I would ask an technician to check this before buying a new part.
    PS: is your BIOS up to date?

  • MagSafe LED always amber - Battery won't charge past 90%

    My 2007 SantaRosa model also suffered from the Navidia 8600 chip failure and I took it in for diagnosis and repair under them unannounced 'recall'. I got it back and all was working just fine... for the first week. It was actually working better than before, and still is except that quite suddenly, the battery has stopped charging all the way up to 99-100%, and the amber light on the MagSafe adapter of the charger will not change to green. Right now the battery will not charge above 90%, and the charger has been attached over-night. The charger is not over-heating as far as my touch can tell, there is no fray in the MagSafeplug, it is clean and it is plugged into a reliable outlet.
    Yes, I did do an SMC reset, ran the long version of the Apple Hardware Test from the install disks, and did do a battery recalibration. The Hardware test indicated that there was no problem with the laptop, and as part of the logic board replacement due to the Navidia problem, the Apple techs also had successfully run the full course of diagnostics - no problems indicated.
    I have a second battery that I installed and still get the same result - incomplete charging and constant amber LED.
    Any of you had this problem or have suggestions of another route to follow in troubleshooting this pain the the rump?? I've Googled this problem to death and not seen a page that mentions a problem where the MBP charger amber light stays on constantly with incomplete battery charging.
    Let's see if the collective powers of this forum have the solution! Thanks in advance to all...

    and I took it in for diagnosis and repair under them unannounced 'recall'.
    Take it back ASAP. If the problems started after the logic board replacement (that's the nVidea fix) then something about the new board or the way it was reassembled is wrong.

  • Macbook pro retina battery won't charge fully

    Hello,
    Im not sure why but my 1 year old macbook pro retina 15inch won't fully charge. It gets to a charge between 75% and 88% and it will at that point stop charging.
    I have attached an image below that shows how the battery has stopped charging. I have taken very good care of this laptop and am very surprised to see such an issue.
    Thanks,
    FF

  • Why does iphone stop charging at 100%?

    I leave my phone plugged into the charger all night because I use one of the many alarm clock apps as my clock/alarm clock. Each morning, though, the battery is charged only to about 93-96% (presumably because when it hit 100% it stopped charging, but the alarm clock drained the battery).
    Is there a way to have the phone resume charging if it dips below 100%?
    Thank you.

    Hi M to the C: Yes indeed the battery does stop charging at 100%. No damage will be done by leaving the charger attached. I leave my charger attached whenever I am near an AC outlet.
    Enjoy
