Endless Switching between Adapter and Battery/Not Charging
My battery is from fall of 2007 (I received it during the recall.)
The little battery icon on the top of the screen is endlessly flickering between the charging symbol and an almost dead battery symbol. If I open energy saver, it tells me that the computer is switching back and forth between the two power sources: my Power Adapter, and my battery, with my battery perpetually stuck at 1%. This seems to me to be more than just the battery not charging, but since my computer is indeed running off of the adapter, I wanted to see if perhaps this was just its way of telling me the battery is no longer charging. Also, any advice on getting the battery to hold something, at least for a little longer (my new job gives me a computer in August, so I'm just trying to stretch this one as much as possible.)
Thanks in advance!

I'm having a similar problem. Will keep scanning the older posts on this board, but:
I just replaced a lost MacAlly G4 Adapter with a new one (MacAlly). It charges the Powerbook when I leave the computer shut-down (so I'm not screwed ...), but when powered-up with the adapter plugged into the G4, the battery symbol alternates between the charging symbol & the battery status symbol - and slowly drains. The screen also dims & brightens.

"Serial Number Not Found" and battery not charging
Hi,
I have a problem with my Compaq mini 110c 1030sf. It started a few months ago, when a weird red message appeared on the Compaq boot logo : "Serial Number Not Found".
Everything was still working fine though, that's why I did not try to fix it.
However, about a month ago, when I started the computer (it had been inactive for three weeks), the battery was not charging. Since then, I can't run the computer using the battery, I have to let the AC adapter plugged.
Windows said : 0%, not charging.
Ubuntu says : 0%, completely charged
I removed the battery and put it back, it started to charge, but stopped after 3 or 4 seconds.
I also tryed updating bios, but it changed nothing.
Could anyone please help me ? ^^If your mini is still within warranty contact HP.
Have you tried the battery test in the HP Support Assistant?
Your BIOS has issues if you have seen that message. That is something you cannot correct on your own as it requires HP's proprietary software to enter the information in the BIOS.
Best regards,
erico

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
Regards,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. -
Battery not charging and makes weird noise when power cord plugged in
I have an issue that a few people have mentioned here, my PowerBook won't recognize when a power adapter is plugged in. I've bought two power adapters recently (that I probably DON'T need now) so I know it's not a bad adapter.
For a few months it has been switching back and forth between wall and battery power but usually only when I was really working the machine either video or photo editing but it has been getting worse.
The thing that is happening to me that I haven't seen mention is my computer makes a fast ticking noise when it is plugged in. Once I unplug it, it stops. And while it was off and plugged in the computer was making a weird whistling noise.
Is this a bad DC/sound card issue and does Apple still do these types of repairs at a Genius Bar or am I on my own?
Thanks for any and all help.I know exactly what you mean. My 17 inch PB has been quite "noisy" since I received it, but i wrote it off (I was too ecstatic that work bought me a PB). Just recently the sound has been getting louder. I'm starting to think the sound was actually electrical interference that was being picked up by the speakers. Actually today I was in a meeting (speakers still working) and the squeeling sound was getting louder (almost embarrasing loud considering I'm the apple diehard in a pc dominated office). I decided to reset my computer (not something I do often)It seemed to subside for a bit.
Well today, it looks as though my speakers have died on me. I'm not getting any sounds out of them. I'm not a newb when it comes to macs (been using macs since os9, about '99) so I've tried everything I can think of to get the speakers to come back. I believe I'm experiencing a hardware failure (reset many times, check all settings).
Hmph.....Pretty frustrating. No iTunes during work makes me sad. I'll have to check and see if my external sound still works tomorrow.

Battery good, Ac Adapter Good, Computer not charging battery or staying on
My sisters 14inch ibook g4 will not stay on. We swapped my ac adapter with hers and her ac adapter works on my ibook. Swapped her battery with mine and her battery works on my ibook. So her battery is good and her adapter is good but computer will only stay on while battery has a charge otherwise is turns off (even while ac adapter is plugged in). Reset power management and all other posted ideas and now I have no idea what to do. The enegry status shows "battery not charging" and its plugged into a regular ac outlet so I am not sure why it says that except the fact its not charging..errr...I am starting to think it's a hardware issue... any opinions?
It sounds like the power input (DC-in) board has failed. This is the part of the iBook which houses the adapter port. The iBook is acting just like my husband's did when the power input board was damaged.

icon reads "battery not charging" with power adapter lit "green". do I replace the battery or the power adapter?
Go to the Apple in the upper left corner and select About This Mac, then click on More Info, then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information back here.

The battery for my Macbook Pro 13 "has only 121 cycles and is not charging anymore, my Mac is telling me that it is necessary to exchange it. You have any tips for me to find out what might be happening with my battery?
Guys, i am actually trying using a solution provided by the article shared by dominic23,
It says "Another option is to get an ionizer to help the atmosphere in the workplace be more conductive and pull charges away from contact surfaces, including yourself."
So in my home, we have such device that could clean the air using ion, and i am using it in my room...
Result: BANG!!! The electric shock on my macbook has gone!! I don't really care about physics but somehow it works! You guys should give it a try.
Thanks again dominic23 -
my iphone is switched off suddenly n then it wont b started it continously shows the apple logo then again switched off automatically and when i charge it so it was switched on and after a long time then it shows battery low and then its also show 4% battery what would i do im very tensed please help ...
Hello s0ha1b
If all you get is the Apple logo and it powering off, then the next step is to put your iPhone into recovery mode and then use iTunes to restore it. If you have a back up, then you can put that on there to once the restore is complete.
If you can't update or restore your iOS device

I have the Kindle app on my I pad
I want to eliminate the books I've already read (I have a LOT).
On the regular kindle you can switch between cloud and device but that is not working on my I pad.
HELP.
ThanksThe Kindle app has a menu on the very bottom center of the screen that allows you to switch from a device and cloud view. To remove a title from the device, tap and hold on it. a pop menu will apear that allows to add the title to a collection, remove it from the device, or download it from the cloud (depending on its current status).

The battery installed is not supported by this system and will not charge. Lenovo X220i.
Hi All, I bought a re-furbished Lenovo X220i and decided to buy an extra genuine Lenovo battery which is brand new (New Old Stock maybe?) from a dealer. Battery Details: P/N OA36283 on the Box. P/N 42T4861 on the battery. According to the Lenovo documentation, this battery part number should be compatible to Lenovo X220i. However, when I insert the battery in, it comes up with a message that the battery is not supported by the system and will not charge. The battery comes up with zero (0%) charge. I installed the latest driver I can find and still comes up the same. Can anybody shed some light on this please? Thanks.
Hi
can you provide the photo of the labels on the battery surface (with quality the symbols legible)? Also, if OS is win7 and Lenovo Power Manager application is installed, it's very helpful to add information PM in the Advinced mode from the Battery tab.
There is a big chance the battery is faked. -
Dear all, I have a problem with charging. When i intend to charge my phone while its on, it does not charge. However, If i were to switch it off and put for charge, it charges. How do i fix this?Help.
First, update iTunes, then connect the phone to the computer and do a restore. This will also get your iOS up to date. Your phone should operate correctly after doing this, if not, you will most likely need to have the phone serviced or replaced.

Battery not charging and MBP not waking up from sleep
I've got both of these issues happening. Sounds like I just have to wait it out on the sleep issue until a point at which Apple will issue a fix. The battery not charging is becoming especially frustrating though. I've had the computer for about a month and it just started a few days ago. I've checked the battery to see if it qualifies for replacement and it has the correct model number but the s/n has a different last for digits. I've unplugged/removed battery/held down the power button and no change, the battery still does not charge. Seeing as the MBP will run with the power cable inserted and the battery removed, I'm assuming that the cable's ok, the light has rarely come on at all lately -- no green or amber. Any advice here? I'm getting pretty frustrated with this thing.
I met the same issue, the difference is while i touch the track pad or move mouse or hit keyboard, the screen responds rapidly and then back to black. tap the keyboard, it beeps... I can do nothing except "command+control+power" to restart or long press power to power off it.
I found it only happens after I installed 10.8.2, it works well before 10.8.2 update.
any help please? -
I tried charging it last night. The shuffle got very warm and did not charge. The indicator light was not on. I just tried hooking it up to the computer with iTunes running and it has been plugged in for 3 hours. It is cool to the touch this time.
The standard warranty is for one year from date of purchase. So, if there is a hardware fault, you may want to have it checked under warranty. If there is a nearby Apple Store, you can do so with an Apple tech support person at the Genius Bar. To make a reservation, use the store's web page

7344 servo motion switching between open and closed loop operation
I have a custom end-of-line test system presently using a 4-axis 7344 servo controller to perform various functional tests on small, brushed DC motors. The system is programmed in C/C++ and uses flex motion functions to control the motor during testing. Motors are coupled to external encoder feedback and third party PWM drives running in closed-loop torque mode from an analog command signal. The system uses all four motion axis channels on the 7344 board to independently and asynchronously test up to four production motors at a time.
In closed-loop mode, the system runs without issue, satisfying the battery of testing protocols executed by this system. I now have a request to add additional test functionality to the system. This testing must be run in open loop mode. Specifically, I need to use my +/- 10v analog output command to my torque drive to send different DAC output levels to the connected motor.drive while monitoring response.
I do not believe the flex motion library or 7344 controller includes functions to easily switch between open and closed loop mode without sending a new drive configuration. I am also under the impression that I cannot reconfigure one (or more) servo controller axis channels without disabling the entire drive. As my system runs each axis channel in an asynchronous manner, any requirement to shutdown all drives each time I change modes is an unworkable solution.
I am open to all ideas that will allow asynchronous operation of my 4 motor testing stations. If the only solution is to add a second 7344 controller and mechanical relays to switch the drive and motor wiring between two separately configured servo channels, so be it. I just want to explore any available avenue before I place a price tag on this new system requirement.
BobJochen,
Thank you for the quick response. The 7344 board does an excellent job running my manufacturing motor assemblies through a custom end-of-line tester in closed loop mode. A portion of the performance history and test result couples the motor through a mechanical load and external shaft. The shaft is in contact with a linear encoder that closes my servo loop.
My new manufacturing requirement is to also sample/document how the small DC motor behaves in open loop operation. Your solution is exactly what I need to perform the additional functional tests on the product I am manufacturing. I see no reason why this cannot work. I was originally concerned that I would need to reinitialize the 7344 board after changing axis configuration. Initialization is a global event and impacts all four channels on the 7344 board.
Using flex_config_axis() to change axis configuration on a single channel without disturbing other potentially running axis channels will solve my concern. It will be several weeks before I can return to the manufacturing facility where the 7344-based testing machine is located. I will update this thread once I verify a successful result.
