Plug problem? Battery problem?

This evening the screen on my iBook G4 started oscillating between bright and not quite as bright (unevenly, but sometimes as rapidly as one second). At the same time, the battery icon would switch between showing the power supply connected and disconnected (battery icon). The battery had drained about 20% in spite of being plugged in. The plug glowed a constant green.
This was a relatively new (2 month) battery, so I got my previous battery which still works but discharges too fast to be very useful and I noted the same problem.
When I switched back to the new battery, it was now completely discharged and the iBook would no longer boot while it was installed. The plug continued to glow green and would not charge it.
After puzzling over this, I checked the output from the power supply and was getting about 22VDC. When I checked the plug with the VOM probes, it suddenly lit orange, so I plugged it back in and the iBook decided to boot up with the drained new battery and worked for about an hour - not charging the battery which showed 0% charged (though it was previously at about 80%), before it went back to a solid green plug and no charging. The iBook went immediately to sleep.
This time, though, I noted that when I wiggled the plug in the iBook, the green light on the plug would go out and I would have to rotate it around and generally persuade it to light back up green. Could not get an orange charging light again regardless of which battery I installed.
Ordinarily I would assume that my problem is probably a bad power supply - most likely the plug has gone bad, but since the new battery totally discharged, or was claiming to be discharged, in a matter of moments, I'm wondering what the deal is.
Any ideas?

Hi, and welcome to Apple Discussions.
+I thought you were supposed to let the battery completely drain every so often to keep the thing healthy.+
Not so. That used to be true with older nickel-cadmium batteries, but is not true with the newer lithium-ion ones in iBooks. Sometimes a deep discharge can actually render a lithium-ion battery useless.
Read about Apple's suggestions on maintaining the battery in this Apple Knowledge Base article:
http://www.apple.com/batteries/notebooks.html
As for using the PowerBook's adapter, that wouldn't harm the iBook's battery as long as the adapter isn't defective (which, with that clicking sound, it sounds as if it likely could be).

Project is unreadable or too new and other problems - battery problem?

For the third time in the last two months, my FCP project has failed to open with the error: This project is unreadable or may be too new for this version of Final Cut. (Previously I was lucky in that my autosaved versions opened, but no on this time.)
The program also unexpectedly quits every fairly often, lately for example, upon closing a project, instead the entire application "unexpectedly quit".
Also, over the past couple of days, once or twice upon startup, it has given me the error: Your computer's clock is set to a date before march 24th 2001.
Are all of these problems related? Do I have bad RAM? Or a dying battery? Would that cause me to have these problems?
I'm running 10.4.9 and FCP 5.1.4 on my G5 Dual 2.3GHz PowerPC G5 with 2.5GB of DDR2 SDRAM. I have already repaired the permissions, deleted preferences and render files. None of my external hard drives have less than 10% free space and my startup drive has nearly 50% free. I am afraid to keep working in FCP because I'm never sure if the project will open up or not the next time.
Also I am currently living in Shanghai where it is 15 hours ahead of California and where it is also really tough to get good Apple support. Any help would be greatly appreciated!

Jim, Thanks for your advice. I restarted using the install discs and tried to repair the disc using Disc Utility First Aid but unfortunately it stopped repairing:
Verify and Repair disk "Macintosh HD"
Checking HFS Plus volume.
Checking Extents Overflow file.
Checing Catalog file.
Invalid extent entry
Volume check failed.
error: The underlying task reported failure on exit.
1 HFS volume checked
1 volume could not be repaired because of an error
Does this mean I have to use Disc Warrior or Tech Tools Pro? If so, which is better?
Also I searched for the Hardware Test disc in my original discs, but all I found was the Install Disc 1 and 2. Going to change the battery next but would still like to test my RAM...

Batterie probleme / Battery Problems

Zu den Akkuproblemen beim 4S:
Es gibt einen Bug der in 5.0.1 sowie in 6.1.1 vorhanden ist und immer noch nicht gefixed wurde. Die "Raise to speak" Funktion von Siri ist das Problem. Man kann sie zwar ausschalten allerdings bleibt die IR LED über dem Lautsprecher nach wie vor leuchten. Ich bin in dieser Hinsicht schwer von Apple enttäuscht! Das vorhandensein des Schalters zeigt ja, das jemand nachgedacht, aber wie kann es sein das dieser Bug über diese zahlreichen Updates nicht behoben wurde. (Ich habe nie 5.1.1 draufgehabt, aber im 5.0.1 und 6.1.1 ist er vorhanden.)
Und wenn jetzt irgendjemand sagt "Soviel kann die kleine LED nicht bewirken" dann hat er absolut keine Ahnung! Ja, es gibt spezielle Low-Current LEDs die tatsächlich nur etwa 3mA Stromaufnahme haben, ABER diese gibt es NICHT als IR Ausführung sondern in der Regel nur in der Farbe Rot.
Bei 5.0.1 gab es die Möglichkeit durch aktivieren und deaktivieren mit anschließendem Hard Reset die LED erlischen zu lassen, allerdings ist das in 6.1.1 nicht mehr möglich. Ich schätze den Strombedarf auf etwa 10mA bis 15mA. Gefühlt macht die LED etwa 30% im Betrieb aus.
Sie ist hauptverantwortlich für die zahlreichen Akkuprobleme. Allerdings ist die Mehrheit der Nutzer nicht in der Lage dieses Problem zu diagnostizieren da man im dunkeln schon sehr genau hinschauen muss, bzw in Besitz eines Nachtsichtgerätes oder einer Webcam ohne IR-Filter sein muss.
Wie kann ein Milliardenschweres Unternehmen so eine Banalität nicht aus der Welt schaffen? Wer möchte soll die Funktion (mit genannten Einschränkungen) aktivieren können, aber wenn man sie auschaltet soll auch die nicht mehr nötige LED auch erlischen!

Have you tried resetting the PMU?
http://support.apple.com/kb/HT1431?viewlocale=en_US
The PMU (Power Management Unit) has control over the charging function, so resetting it may help.

Thanking you.

1. you may have to take it in to Apple and get an out of warranty iphone for $199.
2. you can get your information from a backup of your phone. you do have a backup of your phone right either in iTunes or icloud. If you don't then your answer will be no.

MacBook Air mid-2011 battery problems

I have a mid-2011 MacBook Air, and I recently replaced the battery. Once the new battery was installed, the computer would operate from battery, but would not recognize the AC adapter and charge the battery. If I disconnected the battery, then the computer would power from the AC adapter. After searching this forum, I found that many, many users of practically all types of Mac laptops have similar problems. It seems that Apple has had this problem in various forms going back at least seven years. So, I found suggestions to reset the SMC, which I did. The reset procedure for the MacBook Air is supposed to be the CTRL-Shift-Option + Power button, however this did not work for me. Apple does not want users opening the case to their products, but I already had the case open to replace the battery, so I tried the alternate procedure of disconnecting the AC adapter and the battery, and holding down the power button for 5 seconds to reset the SMC. This worked, and I could operate from battery, or plug in the AC adapter to charge the battery.
This was all yesterday at the office. Then, I took the computer home, and it would no longer charge from the AC adapter. It would, however charge from my Thunderbolt display. Today, at the office, I have taken the computer apart again, and tried both SMC reset procedures again. The only way I can get the computer to charge from the AC adapter is to disconnect the battery. If I disconnect the battery, then plug in the AC adapter, then plug the battery back in, then the battery will charge. However, if I disconnect the AC adapter, it will not charge the battery after I re-connect it. I also have a Thunderbolt display in the office, and its power connecter will charge my computer every time. I have coworkers with MacBook Airs as well, and my AC adapter will charge every other Mac that I plug into it. My computer will not charge from any AC adapter unless I follow the procedure above.
So, to summarize, my computer will not charge from the AC adapter unless I disconnect the battery. I can then connect to the AC adapter and reconnect the battery. This is not a feasible long-term approach because I would like to keep the case closed. My computer will charge from two different Thunderbolt displays. I do not think that there is a problem with my AC adapter, because various other computers will charge from it just fine, and my computer will charge from it under certain circumstances. I have searched the internet for any other SMC reset procedures and have found none. I have noticed in my searching that this problem PLAGUES Mac computers of various types. Does anybody have any other suggestions, or is there anybody on the forum that actually understands the low-level functions of the SMC and how to make this work? I work on electronics for a living and have access to a lab with everything I would need to perform any kind of diagnostics or surgery on this computer.
Please do not suggest that I take the computer to an Apple Store or an Authorized Apple service shop. It has been my experience that the people working there have only the most basic understanding of how to fix anything, and even if they do, the cost is such a significant amount that it would simply be more cost-effective to buy a new computer. This computer is not under warranty, but it is just a little over two years old. It would seem a shame to toss it out.

However, if I disconnect the AC adapter, it will not charge the battery after I re-connect it.
process elimination is extremely easy. Forget the thunderbolt connection.
1. you do not indicate having using another AC charger, regardless of your mention of it working "on 2 diff macs"
2. its unfortunate you didnt borrow your co-workers charger on YOUR Air, or did you?......, because you did NOT mention same.
The 2 capacitors on the charging block board of the charger can easily blow (one usually).
Borrow another charger , a NEW one and verify.
If same, its your IO board.
There's only a 3-component path to diagnose on a battery
1. charger
2. IO board
3. logic board
(4. and the battery itself, but you already claim to have just replaced it).
Its not your logic board, however there is an incredibly slim chance of same, almost none however.
Im going to assume the "new" battery is a genuine Apple battery and not an Ebay "cheap" clunker?
this is what on hand diagnostics and a volt meter are for, which cannot be done online.

Macbook Battery Problem

Hi all, this is my first post, but something weird happened to my macbook that I have to share with you.
Ok, my Macbook Core Duo 2.0GHz (1st generation) have had no problem during its first and half year. Then I left the notebook sitting at home for one month as I was away on business. Came back, the machine won't start, used AC adaptor and showed the battery not charging, "x" and everything. My warranty expired, so I bought a new battery. Once I got that, it worked fine for almost 7 months.
Another business trip left my macbook for 1 month, I came back, the battery is dead again!!! So I went to apple support and bought another new battery. This time I installed it at home, and it doesn't charge what-so-ever. I tried everything from SMU reset, PMU reset, P-RAM reset. NOTHING WORKED.
So I took a friend's macbook battery to try, and it worked! I can charge that battery with my macbook, and my battery won't charge on his macbook. So scientifically I thought its the battery defect. I went to Apple Care and they say they will replace it for me, but think that it should be my macbook's problem. Must be the Logic Board, I explained why I disagree, and that the battery came with only one LED blinking when I got home to charge, the current was already too low to charge.
Anyways, I was able to buy a second-hand battery really cheap but with limited life-span and use it until my replacement battery returns. Everything seem fine and I can charge it up to 100% although it will only last me 50-mins, still not bad, right?
I was reluctant to completely drain this battery now since I am afraid it will drop to zero and won't recharge like the other ones.
I am using Boot Camp, and Vista as well as OS X. Suddenly today, two days after I bought the 2nd hand battery, I was using Vista to show my friend the battery problem is fixed. But suddenly out of nowhere the battery dropped from 95% charged to 0% in seconds. It shuts down automatically, and the battery was flashing one LED indicating it's dying.
I started back in Mac OS X and found the charger able to recharge, but it fixed at 0% for 20 minutes. I thought I am screwed and went out for a smoke. I came back to see the battery charging back to 5% and then slowly to 10%, and 20%, suddenly it went back to 85% in seconds, and then 100%. I try to unplug it and it seemed fine. I left it on without the adapter for 20 minutes, the battery drain normally, to 70% (it's fine considering the battery was 2nd hand) My friend thought I should try to switch back to Vista to see if the same thing will occur. So I did, and before the Vista screen came up, the macbook blacked out. I checked the battery indicator and it's flashing one LED again!!!
So I switched back to Mac side and re-do the charging, this time it took longer to get back to +90%, I thought this is normal, 'cause I did use the battery longer on the Mac side before switching to Vista for the test.
I thought to myself, why Vista drained my battery, and then I remember the first battery that died on me was about the time I switched the PC side to Vista. Prior to that, the PC side was using XP. The second time it died it was in Vista as well. I also remember I wanted to reduce the size of my PC partition, so I trimmed off unnecessary features like hibernation by (Powercfg -h off). It saved 2G in size but it may be causing some problem to the charging circuit for the Mac-hardware??? Don't know for sure.
So I erased my Vista partition, and re-installed XP. Since then I tried both sides without adaptor, usually for 10-minutes or less, and no sudden dropped to 0% occurred since.
Everything else is working fine with my macbook, except the power features. Right now at least I can charge the battery, but I am always worried about when or IF the battery will dropped off and kill itself.
I am waiting for the replacement battery to return from APPLE, and hopefully when it returns, my Macbook will be able to recognize the DEFAULT low-charge of a new battery. I'm still not sure if my macbook is defective, and if it did killed the first battery replacement they gave me a few days ago. If it did kill a decent battery, will it kill this new replacement as well??
I know for a fact that the reason why the machine won't charge the battery is because the current of the battery has become too low for the machine to be able to charge it. If the current becomes lower, the "X" will occur suggesting that the machine doesn't even recognize it's a battery. But what I want to know is what caused the battery to drop to such a low current if I turned off the macbook during storage.
Sorry for the length of this post, but I have to be clear on all the details if I want help, I suppose. Right now my question is (1) Why is this occuring?? (2) Am I right in assuming that by removing Vista with XP, the problem will not repeat?? (3) Is it likely for any new or 2nd hand functioning battery to drop to the state of the other battery any time soon?? (4) Am I doing proper care for my Macbook, and what should I do in the future to avoid the same problem from occuring??

gpotts,
Thanks again, here's my battery profile: (keep in mind this is the 2nd hand battery I am profiling) BTW, something happened when I was doing this message, I left the notebook on for about 20 minutes, it dropped from +90% to 48%, macbook prompted me that the battery is running low. I plugged the adaptor and it went back to +95% within minutes...
Good thing is, I haven't seen the sudden drop to 0% ever since I removed Vista, and also I am able to charge my battery everytime I try now, no more "NOT CHARGING" or "X" indication.
Any clues??? Thanks in advance.

MiFi 4510L Battery problem

Ours MiFi 5410L has battery problems (draining when plugged in). I've called verizon, but they try to get my to buy yet another *** device. I have to use this one because it has a plug for an external antenna, which I have to have in order to even get service here.
With mine, I have to charge the battery in another device, then transfer the fully charged battery to the crapola device and that's the only way I can get it to work. It won't charge while it's plugged in and I had to laugh when someone said to take the battery out altogether and just leave it "plugged in". That does NOTHING. You can't run this *** without the battery in it. The charger is fine, it works on my other mifi cards (we have 3 ) and the battery is brand new, fresh out of the package less than a week ago. It's our 5th battery, btw.
Plain and simple- the device is TRASH. Buy something else through amazon so you aren't stuck in a dang contract.

If you charge a battery too much, over time it will cause it to swell and that will not allow the battery to hold charge like it normally does and it will eventually destroy the battery. What I would recommend doing is Charging the MiFi fully, and then when it gets really or low actually let it die completely, plug it back up and put it on a full re-charge. That would be the best option to get the longest life out of your battery.
hope this answers your question!

Anybody that has ever had, or still have battery problems....

Please join me in finding a solution.
Lets all converse in this thread about battery problems. I Have noticed many many many battery and power problems going unresolved in this discussion forum and I think if we all get organized into one thread and work together we may find a solution.
If you haven't read of my battery and power problem before here is the run down.
-battery won't charge(0% and then eventually "No Batteries Availiable")
-Battery is NEW. It is valid(works in other iBooks).
-Its not the DC-in board. No, no... I replaced that and it did nothing, it probably won't help you either.
-I've done all the pointless stuff.(Resetting PMU, PRAM, NVRAM, Deep Reset PMU)
-Battery is Charged(Used my friends iBook). Yet my iBook will not power on from the battery.
Now. I know many iBook owners are having the same problem. I have worked countless hours on this problem and I am never going to give up.
Now throughout searching countless forums of Battery Problems I have gathered some observations.(All these observations are only taken from cases similar to mine)
-They have the same problems I have stated.
-All the Resets in the world don't help them
-Some of them mention a noise coming from the iBook.
-Some of them mention buying third party power Adapters.
-The thread usually ends with them asking more questions and replies never come so they give up.
-They all usually go unresolved or Solved in the case that they just buy a new laptop.
So taking that I am pretty sure that this problem needs to be solved. I have been giving it a good try but without information I just cannot get too far.
Any of you people with the same problem as me... We should all compare certain statistics and symptoms to see if we can zero in on what the problem is.
These are my suspicions.
I purchased My Power-Adapter from Ebay. It looked legit and everything and it provides the iBook with power pretty well. Yet I stumbled across something. It says on the Power Adapter that it is a 65(watt) Power Adapter. But when I check in the System Profiler, This is what it reads:
AC Charger Information:
AC Charger (Watts): 45
Connected: Yes
Now why would the Power Adapter say 65(watts) but when I check the stats on my iBook it receives 45(watts). I have checked all the stats of these iBooks and I know that they need 65(watts) to function properly. Some people say 45w will power an iBook fine but I think this is why the battery won't charge. The power Adapter I bough online clearly stated that it will work correctly on my model and it Even says 65w on the adapter. Remember the faulty batteries? Could people be possibly making faulty power adapters and selling them now too? My friend has moved so I cannot test his "Apple" adapter to see if it works.
I also think this may be the cause of these processor sounds(That are stupidly diagnosed as HD failures) that some people like me get. I found out if I turn the processor down to "reduced" the sound goes away. Maybe the "whizzing" sound could be a capacitor being overworked so it can provide the processor with power or the processor itself but I really think these issues are related.
In saying that... This is what I want. Anybody out there that has the same(or similar) problems as I do, please do this:
-State the issues you are having with your iBook.
-Go to System Profiler and Under Hardware click Power, copy all of those statistics in the right pane and paste them in your reply.
-Say what kind of iBook(or Powerbook) you have.
-Say what kind of battery and what kind of Power adapter you have.
-Ask for other statistics that you think might help you.
-If you have any ideas of what the problem is please tell me.
-And if you already know a solution please tell us all.
We can all tackle this problem if we work together.

I can't speak to all of your problems, but there are a few things that may help.

You are incorrect about this. The adapter that shipped with iBooks, initially, was a 45-watt model. 45 watts is all it takes to properly run the iBook and charge its battery. The iBook registers the adapter as 45 watts because the iBook only takes the amount of power that it needs. A Powerbook needs the full 65 watts in order to run the computer and charge the battery simultaneously.
Did you replace your DC-in board yourself? Has it ever worked since the DC-in board was replaced? Are you sure you got it plugged in properly?
Yours is acting exactly the way my husband's did when his DC-in board needed to be replaced. That is, it would work from a fully charged battery, but would not charge the battery. A DC-in board replacement was the fix for his, and sounds like that would be the fix for yours, too. If you did it yourself before, maybe you need to either try it again (you could have received another bad one), or send it off to have someone else do it.
Good luck.

Battery problems - with no usable Apple support nearby

Hi all,
Over the past few weeks, my MBP (2.2 SR MBP) has been turning itself off completely whenever the battery power drops to about 45-50% of capacity. There are still three (or sometimes four) lights showing on the bottom of the battery in these cases, but there just doesn't seem to be enough power left to restart the machine. Only if I plug in the AC adaptor I can restart normally, whereupon the on-screen battery meter still shows around a half of full charge. However, if I unplug the power adaptor, the computer will shut down completely again within a couple of minutes. My cycle count is currently at 54 and my battery health usually shows at around 96-100%
I am currently running Leopard 10.5.5 and 10.5.6 (just updated) with all the latest updates. Another problem is that Apple's local services provider in my area is not very nice, they usually turn your beautiful machines into a mess -.- (i had experiences). Is there any other way around ?
Thanks a lot,

This is indeed very strange, Nguyen. Your battery seems to be in excellent health according to the figures you cite, though it is a little strange that it indicates that the battery is not fully charged when it certainly appears to be. Usually when problems of the kind you mention occur the numbers indicate that the battery has a heavily reduced full charge capacity.
It may be a good idea to try resetting the SMC - see http://support.apple.com/kb/HT1411 and http://support.apple.com/kb/HT1894
It would also be interesting to see what the relevant "System profiler" results are when the battery is partially discharged, close to the point where you find it shuts down unexpectedly. If the "full charge capacity" especially varies significantly it may indicate an internal battery problem.
Finally you might try checking the actual battery connection terminals. Remove the battery and make sure that both the contacts on the battery and the computer are clean and undamaged. You could clean them with a little isopropyl alcohol if necessary.
If none of these suggestions help at all, then it may be that your MacBook Pro has an internal problem causing excessive current demand - perhaps an internal short circuit of some kind?
You may end up having no alternative other than seeking hardware repair from an authorised Apple dealer, I'm afraid. Is the computer covered by warranty or an AppleCare agreement?
Good luck

4S battery problem - phone dies, can't charge or turn on??

Having some possible battery problems with my iPhone 4S. I'm on Sprint, with the latest iOS and running on Windows 7. It all has to do with when the battery dies, and has happened 3 times already...
1. battery died, this happened:
(about a month ago)
plug in to PC via USB, low battery sign (with small sliver of red available).
almost immediately (about 2 seconds), apple logo startup screen appears.
about 20 seconds later, vibrates twice.
a second later it flashes the lock screen then goes to black with a spinny wheel for about 5 seconds.
then the apple logo startup screen shows again...and same thing repeats.
does not charge at all. same problem when plugged in to wall charger.
somehow the next day I got it to show "connect to iTunes" screen, and restored the iPhone.
2. battery died, same cycle happening.
(about two-three weeks ago)
I left it alone for a week & set a Genius Bar appointment.
somehow, the day before the appointment, I was able to plug in the iPhone, charge it, and turn it on with no problems at all.
I took it in anyway to the Apple Store and they did a "firmware restore", supposedly different from the restore I did on my home computer.
3. battery died, same crap again.
(yesterday...)
possibly interesting to note was that the battery was fully charged and left alone for the day, but was dead when I checked on it in the evening.
I think something is happening where the battery isn't actually completely drained - so the second time around when I got lucky, the battery had fully run out... so when I plugged it in to charge it didn't try to turn on straight away (because it couldn't).
...Not really sure though.
Any thoughts?????

Could possibly be the battery, I just thought if you remove the battery then try turning the phone on with the charger plugged in and see if that works, but then realised it doesnt as I just tried it, so ignore that one ha ha. Id try another battery in it and see if that solves the prob, if that doesnt work, it might either be totally screwed or just might need re flashing if the firmware has gone down the pan for some reason.

T61 Battery problems

Hi,
I've been having battery problems for the past week with my T61. Although it registers as being 80% charged and the status is 'plugged in' it also says that it's 'not charging'. After this began happening I did a clean wipe and installed Windows 7 and it's still ocurring. My laptop is now pretty much unusable except for when it's plugged in.
My X31 which is over five years old still runs... battery and all (even if the battery does only last for 20 minutes). What's with this battery? The laptop is only 1.5 years old!
Thanks
P.S. Since I'm running win7 I don't have access to most of the ibm toolsuite except for access connections. They don't seem to have provided a new version of the battery management utils.

I've booted into linux with the same issues where there weren't any before and this issue occurred on XP-Pro 32-bit _before_ the windows 7 installation.
I've updated the drivers and got the Lenovo Windows 7 power manager. It's giving me the same error that other people have reported here "A battery error has occurred. The battery cannot be charged". I am at around 200 cycles. There are also a whole lot of people here (http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T61-9-Cell-battery-failure-FRU-42T4511/m...) who have experienced the same issue with the same battery part (i.e. sudden battery failure... no gradual 'fading' as is typical with lithium ions)
Btw, I have the 42T4511 battery and I am four months out of warranty. >< Even with the extended warranty they apparently only support batteries for a year.
It seems pointless to shell out for another battery if it's just going to die in another year and a half. I paid the premium for the T61 and got my old company to buy them because of my experience with the IBM X31 (still going strong btw), but it seems as if quality has gone out the window along with the change in ownership.
I'm getting an MBP the next time around ><

5g battery problem??

Hi,
Yesterday while in class my iPod suddenly stopped playing and came up with 'No battery power remain, please recharge'. I thought, no problem, I'll just go back to my room and recharge it. Got back to my room plugged it into my computer and the computer didn't recognize it and all it did was reset itself every couple mins and display 'Please wait, very low battery'. I left it plugged into the computer for a while and nothing seemed to get any better. I then pulled out an old charger (that goes into the wall) and tried that. I plugged it in and the iPod turned on. I left it there to charge all night and this morning it displayed the usual 'battery charged' screen. I unplugged it and as soon as I clicked a song it turned blank and came up with 'very low battery please recharge'. It keeps doing this. As soon as I plug it into the wall it turns on and says battery charged. If I just plug it into the computer it resets itself over and over and displays very low battery. Once unplugged it comes up with 'low battery'.
This is a 2 month old 5g iPod. Please help me.

My 80gb iPod did the exact same thing last weekend. I've only had it since 1st Jan, and it wasn't even used everyday.
I received the packaging on Wed to send it to AppleCare in the UK for repair or replacement. Sent it off today to them.
Hoping for a repaired or replaced iPod back with me next week.
I'm sort of expecting to see in the media shortly about a battery problem with 5th gen iPods.. Maybe a recall. Ive seen this same problem all over forums etc on the net

Hp dv5 1250 us battery problem

my laptops battery is bout to die, i know this cause it tells me. And because of this, my laptop is constantly plugged in and once it is unplugged the battery drains at an enormous rate. Since the battery has trouble holding a charge, the cord that connects to the adapter port on the computer itself will sometimes become dislodged a little bit, that it will not recognize that it is plugged in. It is still in the socket of the computer, but the light that shows that is plugged in is not on. So what i have been doing in order to turn it on is to move the cord around so the light comes on by twisting rotating pushing it in, anything to try to get the light turned on.
Ssince I have to do that in order for the computer to register that is plugged in I want to know if it is just a battery problem. As it starts up I will get a black screen with blue letters letting me know that my battery needs to be replaced. I am going to replace it soon, I am just saving up some money. Or could it also be a problem with the port for the AC adapter or the adapter itself. I am just wondering considering i have to move the cord around for it to be plugged in.
Thanks in advance,
Jeff.

Mac Switches Off (Is this a battery problem)

My Mac switches off automatically, even if my battary has 68% power left. I can only use my Mac if I have the Power Adapter plugged in.
If I turn my Mac on without the Power Adapter it shuts down before the Apple logo appears. Could this be a battery problem.

Same (identical problem) problem here. A few days ago it was not so evident, I felt like I was taking crazy pills: putting the book to stop and, when back, off.
Anyway now the mbp refuses to be turned on if the power cord is not plugged. Bad.
I'm gonna call for a replace tomorrow. (Little note, this is my third macbook pro. The first had broken isight and the second was a pit of panics.... speechless)

AC adaptor or battery problem?? HELP PLEASE!

When I plug in my computer, the little side light is on, indicating that power is going into the computer. However, it is not charging the battery or giving my computer enough power to come on. My battery still had enough power to work without the adaptor but the computer is now dead. Is this a battery problem or an AC problem?

If ya bought it new, Id take it to the apple store and have them give ya a new battery.

Does anyone having any battery problem?

i went to the apple store this morning and reserve a genius bar appointment, so i went back a few hrs ago to tell them my problems with my iPhone 4.
1. my battery dies faster when its not lock.
he turns off all of my notifications "off" and my turns off my push data for my email. i text my sister a few mins after and she says her notifications are "on" and it doesnt drain her batter at all.
2. i get drop calls as well
so he plugs in my iphone to his macpro to analyze the problem with the "drop calls", it shows none the past 2 weeks, but this past Saturday I was getting dropped calls like crazy.
3. multi-task freezes when i delete apps (so i lock my iPhone to un-freeze it)
he didnt get a chance to explain cuz i forgot to tell him lol
im pretty sure this guy didnt know what he was talking about.
back to the question.. does anyone having any battery problem?

If you are using your iPhone a great deal, the battery will drain. A combination of things will drain the battery in a rapid pace. Even with the new battery size, it'll drain but at an increased amount of time added.
* Internet 3D gaming
* Internet RPG basic
* Internet browsing with music
* Texting with music
* Internet based Videos (YouTube, HTML5 Quicktime, etc)
* Music and local tasks
* 2D or 3D Navigation with live-GPS enabled
* Push Notifications, Push Mail
* Background, FAS, and file transfer multitasking with every bit of RAM used to continue
etc
A handful of combined tasks will rapidly drain the battery. I usually recommend having chargers handy in home, car, and work as I do the same bit.

Plug problem? Battery problem?
