Low Battery Warning and Screen Shut Off

A couple of months ago I stopped receiving the Low Battery/Reserve Power/Connect to AC warning. The computer would just shut down then. This is probably explained by my battery being on a 350 cycle count.
However, a new problem has arisen which I am not sure if it would be connected to the same issue. When running basic software (firefox, excel, etc) the computer works fine, but as soon as I attempt to run something more complex (Google Earth, iPhoto, sometimes iTunes) the screen goes black and becomes unresponsive. This happens whether I'm connected to AC Power or not. When I close the computer, the LED light at the front comes on steadily (not pulsating). I don't think the computer shuts down as the battery seems to continue to run down. The only thing I have been able to do is shut the computer down by holding the power button down.
I have tried taking out the battery and holding the power button for 10 seconds/tone as well as holding the power button (with the battery in) for 5 seconds/tone.
While I am fairly sure I'll need to get a new battery, I'm not sure if that will solve the second problem as well. Any thoughts?
Thanks.

I'm going out on a limb here....
First, have you run Disk Utility to fix permissions, etc?
Secondly, do you only have issues when you run CPU intensive applications? If so, there are two things I can think of off hand. 1 is that maybe your CPU heatsink is coming loose. The other is, I seem to recall reading somewhere that if the CPU is pulling pretty close to 100%, it may pull extra power from the battery... maybe your battery being so low can not supply the needed power? Again.. this is just out in a limb, I don't know this to be fact.

No low battery warning and shut down

My MacBook is no longer showing the "low battery" warning and even with the batery status showing charge suddenly shuts down. If I check manually pressing the button of the bettery flashes 2 or 3 lights.
I have calibrated the battery several times but i am having problems doing it again because after the shut down there is still charge in the battery.
I have OS X 10.5.8 and all the software updates done.
Thanks.

Same Problem is happening to me. I have a Late 2008 13" Aluminum Macbook. If some one knows what to do please post. Thank you

HT1446 No low battery warning before it shuts-down

Under MAvericks OS-X, our MBP isn't giving a low battery warning before it shuts-down. And yes the battery status icon is active in the status bar.. So why no warning??

Read this earlier non-Mavericks discussion: https://discussions.apple.com/message/11218017#11218017

I PHONE 5 BATTERY ISSUE AND PHONE SHUTS OFF

MY I PHONE 5 SHUTS OFF REPEATLY AND BATTERY PERCENTAGE IS SHOWING DIFFERENT NUMBERS

I'd just like to say that ahs70's post on Dec 1, 2013 at 1:17am on Pg. 9 worked for me as well: https://discussions.apple.com/thread/5338609?start=120&tstart=0
If your iPhone's battery is acting up you need to determine if it's a software issue or a hardware/battery issue. To do that, after syncing your iPhone, erase/hard reset all data and settings from your iPhone to what it was from the factory as new. This can be found in Settings/General/Reset/Erase All Content and Settings. Then test it out for a day or two. If it's still acting up then it's likely a hardware issue and you will need to get your battery replaced. If your warranty is done than check out this link to get a battery kit to replace your iPhone battery yourself: http://www.ifixit.com/Store/iPhone/iPhone-5-Replacement-Battery/IF118-001#produc tDescription
If your iPhone is now working properly after hard resetting it than it's most likely a software issue. This battery issue only started after upgrading to the new iOs7, so it is obviously related to the update not properly installing itself. What has worked for me and many others is to manually update to iOS 7.0.4 using the full downloaded version of the update which is about 1.32 Gigs.
But first you need to find out what model of iPhone you have, click here to determine if it's GSM or CDMA: http://support.apple.com/kb/HT3939?viewlocale=en_US&locale=en_US
Then go here and scroll down to download the iOS 7.0.4 complete update for your device: http://www.downloadios7.org/download-ios-7-0-4-ipsw-file.html
Then scroll up on the download page and follow the instructions of updating your iPhone manually following the instructions below: "IPSW with iTunes"
And your done.
Problem solved.
I only posted this because it was a very frustrating problem that no one really seemed to figure out a solution for.
I hope this helps.

My ipod will not charge will either a Memorex docking station or USB port on Windows based operating system. It did work at first but even after charging overnight I get a low battery warning and turn off.

I downloaded music from a Mac at my daughters house when I first got my Ipod several years ago and everything was fine. I continued to use a Memorex charging station (travel speaker). About 6 months ago it failed to charge on the docking station so I tried my USB port on my computer. It would not charge either but I also got a message saying I needed to reconfigure the Ipod to Windows (my operating system) but would loose all my data. Ouch! Any suggestions?

I would charge it for at least an hour (vice the two minutes you did) and then try resetting it. I am afraid that there may be internal damage that is causing the problem and repair is the ony option. Apple's prices are:

N97 Low Battery Warning

Is there a way to manually discharge the battery on an N97? Or alter the time between getting the first low battery warning and complete battery discharge?
From the first time I get the warning to actual discharge takes ages.Yes that can be a good thing but if, like me, you prefer to let the battery completely discharge it can be like waiting for Christmas.
I know I can use the music player, camera, video etc to help discharge the battery. But is there a more specific and faster way?

You should not let the battery discharge completely. It can damage the battery. The battery prefere to have as much juice as possible on it all the time. Once a month you could discharge it to like 10-20 percent.

No low battery warning, just shuts off

I have an Core Due Macbook back from September 06, and recently I've stopped getting that low battery warning message. Now my laptop will just shut off at 20min (sometimes even 30min) without any warning. I tried recalibrating the battery, it solved the problem for one charge (I saw the warning message once) but after that it went back to shutting off at 20min again. I've heard that Apple has extended their battery coverage, but my laptop is at 315 cycles now. I do have the extended warranty though-will that cover a replacement battery?

Hi. Recalibrating the battery does not prolong battery life. It will only help in getting a more accurate battery charge when using the computer on battery power alone. What you can do is make sure that you have the battery update and latest software from apple. Also, try resetting the SMC of your computer. Here are the links for more info. Hope these help.

30GB iPod Video not being recognized by iTunes and low battery warning

This is without a USB connection to mu Vista machine
1. I hear a clicking sound (it comes from the HD) on start up.
2. A dark Apple icon appears
3. Then the back light comes on with the sad face iPod icon and exclamation point.
4. It then shuts down and screen goes off.
Plug it into a USB port and same issue but the screen shows an un-backlit "Please Wait Very Low Battery" message.
If I leave it plugged into the USB port it just cycles through the process.
Note too that the iPod is not recognized by iTunes.
I have done the reset process without success.
I thiught I had a bad HD and/or battery so I replaced both. I get the same issues.
Anyone have an idea?
DAve

Well I tried putting the old hard drive back in and it was recognized in iTunes. All is well now.
I think the issue is that once the battery is totally run down there is no way for the thing to get enough power from a USB port to bootstrap itself.
I finally let thing recharge from a wall adapter all day.
I suggest you try to get it charged via the car adapter overnight. Of course the car port must be supplying power with the key off.
The Apple store people said they fix this type of issue by charging the ipod for 20 mimutes with a high power charger (I assume this is a 1394 type).
All these issues coulkd be solved with a better design,

MacBook shuts down after low battery warning

Hi,
up until recently my macbook's battery has been working just fine. but then lately i noticed that a few minutes after it displays the low battery warning it shuts down by itself.
before, when the low battery warning would display i could still continue working on my macbook for several minutes until it goes to sleep -- only then would i connect it to the power cord.
unlike the other posts (concerning batteries) that i've read, i have no problems turning my macbook on/off before or after this event has occured. neither does it shut itself down when the battery is halfway. my problem really only happens after the low battery warning has been displayed.
i wanted to calibrate my battery but then that would require my macbook to go to sleep once it reaches a battery level of less than 5%-10% -- mine just shuts down completely.
is this shutting down thing a substitution mechanism to save the laptop's memory -- instead of going to sleep, it'd just shut down?? how can i fix this?
thanks in advance for the help.
MacBook Mac OS X (10.4.8) 512MB, 2GHz Intel Core Duo

For what it is worth, I now have the same issue. Only I don't even see the low battery warning, it gets to 15% or 10% and bang, no power. This is not good, by the way and is bound to corrupt something in the system as OSX requires some house keeping when you shut down the computer properly. This instant off is not a proper shut down. I took my MacBook in and they wouldnt simply replace the battery, they want to keep the computer and give it back to me in a few days. I rely on this puter for work 5 days a week, so I was trying to avoid this.
Oh well I guess a trip to the Apple store is unavoidable.

I can start my iPod but it will only stay on the Apple icon screen for 5 minutes and then shuts off, what do I do to fix this problem?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Shut down after low battery warning

Hi
After I get the low battery warning on my iBook G4 (about 30 seconds) my iBook unexpectedly shuts down, I have tried recalibrating the battery several times, including shutting the lid to put it to sleep after the warning then plugging it in and waking it (to recalibrate you are supposed to wait until the machine sleeps) and letting it charge right up.
I have also tried resetting the PMU, although I dont think this is working as I hit shift-ctrl-apple/option-and the power button, and all that happens is the machine starts up as usual, according to the documentation, I should have to then power up the machine.
Is itr just that my battery hasd had it? I have notice it only takes an hour/hour and a half to run the battery down, and only about 30mins or so to charge.
Thanks for any help in advance.
Mike

That definitely sounds like a battery that wants to be replaced.
My iBook behaved in a similar manner--except the "low battery" warning wouldn't even show up!
I think it's time for you to pick up a new battery--they run about $100.

Ok. so I updated to iOS 5. Downloaded it from iTunes and all. But in the middle of installing the iOS, i fell asleep. not knowing my computer was at a low battery charge my computer shut down. I did a DFU already but i'm not sure if it the os is complete.

Restore to factory settings. That will use the latest iOS and then restore from a backup.
Never, never, never attempt an update/upgrade on any portable computer device without plugging it into its AC charger.
