Battery won't Charge is it Adaptor or Battery?

My AC Adaptor is correctly plugged in to my iBook, the light turns either amber or dark red like it usually is when it's charging, but the battery won't charge. The light's on the battery don't turn on and the computer won't turn on since the battery is dead. When I press on the battery button quick green flashes happen saying it's dead, so my question IS THE BATTERY DEAD OR IS MY ADAPTOR BROKEN?

This is turning out to be an epidemic. I have an ibook G4 800 and it started doing the same thing a couple days ago. I have another ibook that I charge the battery in, then put it in the G4. But the thing wont start up off just the power cord, and it wont charge the battery. I've reset the PMU and the PRAM, and this hasn't helped anything. 299 for Apple to repair it. But I do get free overnight shipping both ways. That was nice of them.

  • Almost new battery won´t charge, does not work on AC

    After spending a few days in Taiwan (110V) the battery of my PB G4, A1138 won´t charge any more. Power connector lights amber.
    After coming back to Austria, i connected the PB for 2 days and it would charge again and worked proper. Now, 2 months later, the battery again refuses to charge, coconut battery & system profiler say that there is no AC power connector & battery is not charging. It won´t power up with AC connected. I did the PMU reset and PRAM reset - no effect.
    The battery is an original Apple replacement and has only 40 loading cycles. i´ve measured the voltage at the battery connector in the battery slot (3V & 6V depending on the pins), so the charger provides voltage.
    Can anybody tell, if the DC-in board is faulty or if it´s the logic board or something else?
    I´m thankfull for any advice!

    It's fairly common for the pre-MacSafe power connectors on the computer to loosen due to stress. The points where the barrel-shaped chrome connector assemble is soldered (or flowed) to the logic board lose contact and you get intermittent charing at best.
    If you connect to A/C adaptor and gently wiggle it up and down, can y ousee charging start again/ "Up" is the position where the contact should again meet.
    My 1Ghz 17" MBP will not start on A/C alone until the battery has a little charge. I don't know it's the dead internal backup battery (common) of something else that causes two good 65W power supplies to report in Profiler as 45W.

  • Battery won't charge, adapter shows green

    My battery won't charge. The adapter light shows green. The System Profiler says:
    "Battery installed: Yes
    Remaining capacity (mAh): 0
    AC Adapter cannot charge battery: Yes
    AC Charger (Watts): 0
    Connected: Yes
    Charging: No"
    This started suddenly, as it was working fine yesterday. Overnight the battery ran down all the way. I reset the PMU, but no change. This is a replacement Apple battery now about 2 months old. The adapter works fine, as it works on my other laptop. I used a different adapter, just to make sure, but it didn't work either. So, it's not the adapter. The menu bar shows the battery symbol with a plug inside it with "calculating" constantly showing beside it. Is the problem with my battery or some more serious hardware problem? Thanks for any help.

    Similar but different?
    Battery won't charge - coconut says 0% BUT I know that there is charge in the battery because I opened it, located the terminals and applied a slow charge (12.2 Vm current limited at ~ 250-300 ma overnight and now battery open circuit voltage is and holds at 12.2-11.1 volts. Power adapter shows green. Machine goes to sleep if pull power adaptor.
    BUT the internal charge monitoring circuit in the battery pack needs to be reset/reinitialized.
    Tried to reset pmu, pram, nvram to no avail icon in upper right shows 0%

  • Battery won't charge - intermittent

    Noticed this problem recently. The orange light is on but my battery won't charge. Although the battery is old (55 months) Coconut says capacity 100%, charger connected but that the battery is not charging. Intermittent charging does occur when powerbook swithched on. The power adaptor seems intact. Have reset PVRAM. Tried most other solutions I have seen and nothing working. Any suggestions?

    Hope John Mitchell doesn't mind if I piggyback on his thread.
    I just noticed a similar problem on my Powerbook G4 12". It's more than 3 years old and I recently installed Leopard. I pretty much leave it plugged in most of the time; in fact, I think it's been a few months since I used the battery.
    Anyway, the AC adaptor light stays green but the battery won't charge. I tried taking out the battery and putting it back, unplugging the adaptor for 60 seconds, checking the adaptor and "duckhead" plug and resetting the PMU. None of them have made a difference.
    Curiously, I keep getting a message on restart that says my internal clock is set to prior than Mar., 2001 but when I went to Sys. Prefs, that wasn't the case.
    Also, a couple of times, such as right after resetting the PMU, the orange light came on before I restarted but then it went to green and the battery won't charge.
    Is my battery just old and I need to get a new one?

  • PowerBook G4 won't charge battery

    Hi all
    My last-generation PowerBook G4 won't charge its battery. It will run fine off of its power adapter, but it won't attempt to charge the battery, which the system states as having a 0% charge.
    I don't think it's the battery; the last time I ran the PowerBook off the battery a few weeks ago, the battery was still holding a charge for over an hour. The battery has been used for 179 cycles; iStat Pro describes the battery health as being 87% (this may be wrong, of course, since it is also describing the battery as charged). The PowerBook just isn't trying to push a charge to the battery.
    I only use my PowerBook every so often; usually it spends its time off, and not plugged in. Last time I found the battery had completely drained, to the extent that the clock has lost its time, so I put it on to charge, and left it. The next time I tried to use it was when I realised it wasn't charging. The notebook hasn't taken a knock that I'm aware of (at least, a new one), so I'm not sure why this is suddenly happening.
    Any help or ideas would be appreciated. I don't want to waste time and money dropping £100 on a new battery if the issue lies with the PowerBook itself.
    Cheers!
    (PowerBook specs: 1.67GHz PB G4, 2GB RAM, Mac OS X 10.4.11)

    Well, I left the laptop unplugged (and with the battery out - not that it would've made a lot of difference, since it doesn't currently have enough juice to highlight ANY of the charge indicator LEDs) for and hour and a half, booted the machine, and the clock kept its time. I'm not sure what that proves at this point, if anything.
    As for the charging circuit, well the computer still isn't charging the battery (the main battery, not the PRAM battery). From your suggestions, the socket seems fine, maybe a touch lose, but then it's not exactly new, and my old adapter used to be worse. The only similar charger I have to hand is an adapter from an iBook that's about a year older, so I'm not sure the wattage will match. That said, surely since the adapter is actually powering the computer, it won't be the adaptor or the DC-in board, since I assume they are also responsible for getting the power to the computer itself?
    I assume (and I am assuming here) that it is either a knackered battery or logic board. This machine has already had its logic board and DC-in board replaced, for what its worth, back when it was only 5 weeks old (probably irrelevant).
    Thanks for your help thus far!

  • IPhone 4 battery dies quickly, won't charge properly and is very hot!

    Hi, my iPhone 4 won't charge properly and the battery drains really fast plus the handset is very hot. Does it need a new battery?
    It just suddenly started happening yesterday before lunch and hasn't been right since! I haven't done any software updates or anything that could cause it. I e tried deleting my mail accounts, turning phone off and re installing them as suggested in one post but that didn't work!
    Thanks

    Downloaded new iOS for iPhone 5. Now the handset is running hot, keeps freezing on different screens, won't charge on official charger ( only charges on crap poundland one) and battery is loosing 1% every two minutes! I've closed all apps and reset the complete phone but no luck. Any one know what else I can try apart from a new phone?

    I have done a factory reset at 45% battery. After the reset it's still hot and at 35% now

  • How do I restore my Ipad 4 from my desktop computer? My charger was broken. I bought a new one but now it won't charge. I have a BATTERY bar in the middle of the screen that is flashing RED and I have a symbol on the bottom that looks like a charger.

    How do I restore my Ipad 4 from my desktop computer? My charger was damaged so I bought a new one but it won't charge. On my Ipad, I have a BATTERY bar in the middle that is flashing RED and an icon on the bottom that looks like the end of a charger. I have tried to force into reset mode, by holding the sleep key and home button SEVERAL times but it does NOT work. I have plugged my Ipad into my desktop computer, but I do not have a screen on my desktop that is coming up. THIS HAPPENED BEFORE AFTER I DID AN UPDATE AND WAS LOCKED OUT AND I USED EITHER ICLOUD OR ITUNES TO RESTORE, NOT SURE WHICH AND I FORGOT HOW.

    Hi MrsMoosie,
    I'm sorry to hear you are having these issues with your iPad. If your iPad isn't responding or doesn't appear to be charging, you may find the information and troubleshooting steps outlined in the following articles helpful, in particular the following portion:

    The iPod touch 5 battery won't charge, the iPod battery gets hot and doesn't turn on...  What is wrong?  Can photos and data be retrieved?

    - See:      
    iPod touch: Hardware troubleshooting
    - Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
    - Try another charging source
    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
    - Make an appointment at the Genius Bar of an Apple store. I suspect a hardware problem  due to the hotness. If iTunes can't see the iPod then uor only hope if to contact a data recovery company for getting data off the iPod. If you have an iPod backup you can restore another iPod, iPhone or iPad from the backup to get the data that was in the backup

  • Battery won't charge

    I had my MBP for 3-4 months now. My problem is that the battery won't charge when it has more than a certain persent. If it goes red (the battery indicator on top), then it charges to 100% but before it charges to 100% the light blinks green, amber, green, amber (like the one mention a few post before mine). When its at (lets say) 85%, it won't charge, all I get is a green light from the magsafe indicator and its stuck there. The persent indicator on the screen doesnt move as well, I also check the led indicator at the bottom of the battery, one led is not lit. I did the reset the PMU as well as battery calibration it didnt help. I'm down to like ~ 4200 mAh. It has like 11 charges since I got this, age of the machine is 4 months. So I can't call apple to ask for help unless I want to pay like $56 for a week of tech support or buy the applecare (I only have 90 days of telephone support, and it ended a couple of weeks ago). Any way I can email apple or something?
    MBP 15"   Mac OS X (10.4.7)  

    Because it says invalid. Apparently, they forgot to put a "it must start with 6N"
    The website should say (according to the apple tech):
    Identifying your battery
    The affected batteries have model number A1175 and a 12-digit serial number that begins with 6N and ends with U7SA, U7SB or U7SC. To view the model and serial numbers located on the bottom of the battery, you must remove the battery from the computer. The battery serial number is located above the barcode. See photos below. Only batteries within the noted serial number ranges need to be exchanged.
    Edit, it says:
    One or more of your serial numbers didn't validate.
    Please check the serial number and try again. Or, in the United States, call 800-275-2273 between 6 a.m. and 6 p.m. PST for further assistance. For other countries, please use our contact page to find the appropriate support number.
    So I called Apple Support.
    I read the FAQ 5-8 times.

  • Battery Won't Charge & Can't Update OSX Beyond 10.4.6

    I'm a relatively new Macbook user, so any insight would be helpful.
    Here's my plight:
    My battery won't charge, so I called AppleCare and they told me to download the latest FIRMWARE for the battery. (This is after re-setting the battery, and pressing the button located on the BACK of the battery, hoping to get the three-or-four green lights... I'm getting nothing).
    I came here and downloaded a battery fix/update - the problem is that the battery fix requires my OS to be 10.4.8.... I have 10.4.6... And I can't log onto the internet (another 'fun' issue) through my Macbook in order to download anything beyond 10.4.6....
    So, now, I downloaded 10.4.7 from the apple website, off my Windoze PC, yet when I try to load 10.4.7 on my Macbook, the set-up goes through the motions, then STOPS after I ACCEPT the terms, and tells me that I don't have a (I'm paraphrasing) proper HD to store the updated version.
    No more than two months ago I had to get a new HD (after only having my MacBook for six months) and I'm not looking to get another one...
    Since the root of my issues stem from me not being able to upgrade... Any thoughts on how to upgrade, even though I can't connect my Macbook to the net?

  • Brand new G780, battery won't charge

    I got my G780 a month ago. It was brought to me from USA (I'm in Europe) where it was only tested for a few minutes. Yestarday I started it up for the first time. Battery stays on "0% (plugged in, charging)" and it won't charge. I tried to take it out and hold the power button for a minute - nothing.

    hi,
    Can you try turning on the system without the AC plugged in see if that'll work.
    If it does not turn on I suggest you check this international Warranty Hotline numbers.
