Battery failure OR charger failure?

Quite suddenly I notice that the little light on the charger plug is no longer lighting. At the same time the power left in the battery is gradually falling when in use.
So....... do I have a battery problem or a charger problem. The battery is about four years old.
Is there any test I can do to check which one is the problem?
Thank you,
David

You have a 4-year-old battery with only 17 cycles? You should be calibrating your battery once a month or so:
http://docs.info.apple.com/article.html?path=mac/10.4/en/mh2339.html
However, it sounds like you may have a charger problem. Try the MacBook with a known-good charger, from a friend or at the Apple Store. That will clear up what the problem is.

My IPad1 has completely shut down. It has no power. I have tried a restart and a reset with no results. I have tried charging through the keyboard dock, the wall charger and my Macbook Pro with no results. Is this a complete battery failure?

My IPad 1 has lost complete power. I have attempted a restart and a reset without results. I have attempted to charge with the keyboard dock, the wall charger and connecting to my MacBook Pro. Again no results just a black screen. Is this a battery failure? I am in Mexico for another 6 weeks and hoping to find a solution.

Cathi-
How long did you have the iPad connected to the wall charger? A completely dead iPad battery may not work until it has been charged for some time - maybe a half hour or more. I suggest leaving it on charge overnight, and then trying the reset.
The MacBook may be able to charge the iPad if it doesn't go to sleep, but it will be extremely slow. the Wall charger is definitely the best way.

I pod will not charge. Battery Failure??

Ok, I have seen this posted before and I have read through all of the suggestions, but none of them have worked so far. Any help would be great.
The computer recognizes the Ipod, when plugged into the usb its glows solid yellow like it is charging. A few hours ago the light turned green... fully charged right? But when I unplugged it, the battery light did not come on. And the pod did nothing. Ok.. maybe it wasn't fully charged. I plugged it back in and now it is still charging again like it had not been charging at all. I have charged USB ports to see if this would help, but could this just be a broken battery situation. At one point it was working, then it just seemed to have died. I have had problems from the start with this thing. Suggestions?

Maybe it's the cable itself that is faulty. Have you tried it with a new USB cable?

IPhone won't turn on... possibly a sudden battery failure?

Hi,
So my iPhone was working fine, i received a call, put it down... but next time I go to check something I push the home button and nothing happens.
I've tried turning it on - nothing, charging it - nothing, taking the sim card out etc - nothing.
I tried calling too, and just goes to voicemail.
I bought it off a work colleague as a replacement for a lost one, so I have no idea of the serial number, and its definately out of warranty.
Any idea what the problem is? Feels like a sudden and total battery failure, but I don't even know how I'd get that sorted/replaced!
Please help me someone!!
Thanks, Matt

Does it charge if you connect to the adapter? If yes, let it charge for about 20min. then connect in recovery mode: http://support.apple.com/kb/HT1808
If it does not charge, contact Apple to get it serviced, see these details about the battery replacement program: http://www.apple.com/support/iphone/service/battery/
or more on the Out-of -Warranty Service here: http://www.apple.com/support/iphone/service/faq/#warranty7

Hi,
I am working on restoring a very old system built using PXI8156B, attached are the snaps.
The system has damaged OS. I want to restore by ghost image which was captured just before final system was ready for operation.
The CPU module has battery failure which cause "Loading defaults" thereby booting from C. I tried making boot sequence "A,C" but was no success.
I would like to know how do I restore the battery..? There doesn't seem removable battery.
How can I restore the ghost image if battery solution fails..?
Kindly advice.
Thanks and regards,

I would like to erase a partition that I have on my 30gb internal harddrive.
Do you have more than one partition on the HDD? I suspect you have only one since the HDD is only 30 GB.
Your computer is now 8 years old, as is the original HDD. The average life of these drives is 3 to 5 years, so your HDD is well past old age. You may be getting the error messages because your drive is failing.

Premature CMOS 2032 Battery Failures

There have been many reports in this forum lately concerning premature CMOS 2032 battery failures.
If there truly is a common CMOS battery problem with MSI systemboards
we need to start to find the solution by identifing what vendors battery is failing and on what boards.
My mobo is MSI K8N Neo4 Platinum (G52-M7125X1)
My original CMOS battery was a KTS Lithium CR2032
It lasted about 1 month then the systemboard failed to POST.
I replaced it with a Energizer Lithium 2032
It has worked for a week so far.
The 2032 is a Lithium-Manganize Dioxide 3.0 Volt Button Battery.
It is designed not for recharging.
Life expectancy is least 2 to 4 years
A new 2032 battery unused and right out of the package measures 3.26Volts DC.
The new 2032 battery in the motherboard with AC power on, measures 2.97 Volts DC.
A defective KTS CR2032 battery out of the motherboard for days measures 2.97 Volts DC.
A defective KTS CR2032 battery in the motherboard with AC power on measures 1.41 Volts DC.
I used a Fluke Series 77 Digital Multimeter for the measurements.
My Phoenix-Award BIOS Version 1.4 - PC Health Status of the good Battery = 1.66 Volts
I have no idea what that means other than the BIOS is not reporting accurate battery voltages.
If you just have to know all there is to know about batteries try these sites:

New battery failure

I just got a newly refurbished ipod classic 7th gen 120gb. I have had it for about three weeks and the battery is not working correctly. I charge it for hours then the battery is never charged past 50%. It drains in half an hour. It has been in my car when its coldm but its not under the temperature specified by apple. Plus, the battery has not returned to working order after warming up. The seller claimed to have a new battery. Is it just faulty? Do I need to get a new one or am I doing something wrong? Not sure if this matters or not but i have it play when I sleep, so it continually charges every night.

It was from the exact same version HotSync.
I don't use the Palm Desktop.
I did solve the problem though after 2+ hours.
1) I synced the Tungsten, creating a new user, with blank data.
2) I then simulated a dead battery by doing a hard reset on the Tungsten.
3) I then substituted my new blank data folder (under My Documents/Palm OS Desktop/(hotsync name) with my old data folder, from my back-up hard drive.
4) I then did a hotsync, which now had the Hotsync name to choose, and sensing that it was a blank Tungsten, all old data was reinstalled.
5) Thanks for the help

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.

Battery doesn't charge but ibook still runs on ac?

I've got a 2004 iBook G4 1.0ghz processor 1.25gb ram. Had it 16 months, no problems so far until today.
When I plug in the AC the laptop runs off this power- the battery symbol changes to show the power plugs- but the battery does not charge. It stays at 49%, no matter how long I wait. I tried inserting my backup battery and it doesn't charge either, it just stays at 26%. The laptop will run off the battery if it needs to, I just can't get any more power into the battery itself. And the leds in the adaptor do not change colour anymore, they are always out. Applecare recommended a PMU reset, which I did, but nothing changed. Next recommendation was to take it in to the shop. I'm hesitant because my original iBook never really came back from the shop... it had 3 logicboard failures and a hard drive failure in the first 90 days. My current iBook is a replacement. Hopefully this is not logicboard as well. If there's anyone out there who has experienced something similar and has some non-invasive advice please help! Thanks.

Same here with my AT270 bought in January 2013. The tablet does not load and remains on the screen with the red battery without recharging.
Even powered on, the tablet does not charge.
I am looking for a replacement battery, but the one I found on the web are more than 50€ would you have a better price?
Thank you in advance.

Brand new MSI GE70 2OC battery won't charge

Hi all
I have a rare issue related with the laptop power system of a brand new GE70 2OC: basically, the battery won't charge.
-In Windows 8, with the battery installed and charger connected to the laptop: the battery does not charge and drains.
-If I boot with a linux live cd, exactly the same happens: there's no charging, and the battery is draining.
And here we go with the mess...:
-If I start windows8 only with the charger connected (battery removed), the computer turns on properly, windows start booting, but before showing the home screen, the laptop turns off. As if power were suddenly removed.
-If I start the same way (only with charger, battery removed), and entered the bios, I can stay here forever: laptop doesn't turn off until I wan't.
-If I start the same way (only with charger, battery removed) with a linux live cd, I can work without problems every time I wan't
It's very strange... If the battery is not dead, I think may be some kind of BIOS or firmware issue, because the failure of "battery not charging" appears in any situation (turned off, in bios, in windows, in linux).
The charger is not broken. It runs smoothly without battery in bios and linux.
I tried a EC Reset. Nothing happens... ¿Any idea?

Thank you both
I'm still in the 7 days money back guarantee from the seller. I've contacted the shop, but still expecting for news.

MacBookPro Battery: cannot be charged!

My MacBookPro, about two months old, is working well, except that the battery is not charged up for last three days. System profile says that
Power
Connected: Yes
Charging : No
Besides, the orage light is not on at a little white connecter.
So as far as my MBP is connected to the power supply, I can use it.
I called the call center. A lady kindly replaced the power supply white box, but it does not help at all. So I called it again. This time the other girl offered me to replace the battery. I will see the result hopefully in a few days.
It seems to me that the hardware is not the problem, but that some softwares made the trouble.
I would like to have some suggestions from the exerienced people.

It may well be the battery. All lithium polymer (and lithium ion) batteries have a built in microprocessor. If that microprocessor detects a condition that could lead to catastrophic failure of the battery, it will shut the battery down permanently. It is there to prevent overcharging of the battery because overcharging a lithium battery can lead to a serious problem.

LED did not lit up and the battery is not charging

I'm using Macbook model A1342 late 2009
For the past 4 months or so, it's been hard for the charger connect to properly connect and charge. However, it has always worked when I wiggle the connect a bit. Last week, no matter how hard I try, it won't charge. I tried to use my friend's charger but still, it wont charging. I can still turn on and off my laptop while the battery is about 40% left. I even install the Macbook application install DVD for apple hardware test and it said that my laptop is working properly. Untill the battery turns 0% and it shuts down on its own. I first thought it was the battery failure. Then, I sent it to a local apple service centre in Russia to make sure whether I can change a new battery. They run some diagnostic and said it wasnt the battery, it was the logic board! I never spill any liquid on it. And how is it possible that the logic board is broken but I can turn it on???? Can someboy please help me??

But what about yours with her computer? Just to be sure the cause is not a banal contact of the plug. If yours is also OK with hers, then concentrate on other possible causes, i.e. battery or worse, the contacts inside. It isn unlikely to have a software issue, i.e. a corrupt system, which does not correctly read/send data, but chck this too. The simplest way is to connect your mac via firewire to the other mac, and start it in target mode; and vice-versa. You should thus check if systems are OK.
For starting in target mode look up in apple.com, i.e. here:
http://support.apple.com/kb/HT1661?viewlocale=en_US&locale=en_US
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8443.html
When clear that system is OK, concentrate on the other hardware issues. The logic board may indeed be the big trouble, as you cannot repair it, and replacing it may prove too expensive.

4 days old MBP 13". First boot up showed charge of 100%, next boot up showed battery fully charged but the percentage read 98% in the subsequent boot ups the battery is fully charged but percentage reads 96%. Whats wrong??

I recently purchased a 13" MacBook Pro. On my first boot up, the battery charged to 100%. I didn't operate this thing on the battery. The next time I booted this thing up, the battery was charged but the meter read 98%. In the subequent boot ups of this machine, and I still having not used the battery, my battery is fully charged but the meter now reads 96%. IS there some problem with the hardware or the software? Help is appreciated!!
Thanks.

hey thank you for the info. Based on what happened, the battery has gone up to 100% just once when I booted this machine for the first time. On subsequent occasions the Battery Charged symbol has appreard at below 100% charging. I have been using my MacBook Pro for the whole day with outlet power and never did the battery go back to 100%. I hope I don't have to calibrate the battery on this model?
