Is my battery dying?

This morning the battery on my computer was at 32% then all of a sudden my computer went to sleep. I plugged the power in and the battery then said it was at 0%. I've had my computer since may 2007 and use it every day for work. I've never had this problem before, but my husband did a few years ago when his PowerBook was about six years old (he also used it everyday for work). He bought a new battery and that solved the problem.
At less than 3 years old it seems a bit early to be happening, but I wondered if this meant that my battery's on it's way out?
If this is the case can I run my MacBook Pro off of the mains without the battery being connected and will this, in a few months or so, mean the battery will have regained some of it's life. Or am I just going to have to face facts and buy a new battery?
Also will running my machine off of the mains (either with the battery connected or not) long term cause any problems?
Thanks

Before you purchase a new battery make sure you have installed the latest MBP Battery Update. That alone may fix the problem. To check go to:
HD/System/Library/SystemConfiguration & look for a file called batteryupdater.bundle. Select Get Info for the file.
If its version number is 1.2 or 1.3 you should be fine If not, or if you cannot locate a batteryupdater.bundle file (by using Spotlight, searching manually or using a 3rd party search feature) then download an update from Apple's website & install it. If installing has no effect, you probably need a new battery.
Your battery may be replaced for free. Take your computer to an Apple Store. The staff will be able to check to determine if your model MBP qualifies for the free battery program.

My battery died and then when i charged the phone it is asking me to connect to itunes and restore. if i restore how can i get my data back

My iphone battery died and on charging the phone it asked me to connect to itunes and restore the phone.
If i restore the phone how can i get my data back and how can i check when i last backed up my phone

If you have been syncing regularly as the iphone is designed, then you can sync the data back.
Regardless you will have to restore the iphone.

Try rebooting your iPhone (holding the home button and sleep/wake button together until the apple logo appear)

How do i fix my issue: Apple Logo flashes on and off after iphone battery died during IOS update?

I've tried the methods I've seen on youtube and other iphone tech help sites but I am still having the same problem. Today while updating to IOS 7 my iphone 4 battery died and I didnt have a charger, now that I am home an I put in on the charger I notice the apple logo just flashes on and off. I've tried to restores using the DFU mode with the home and power button but that only seem to stop the logo from flashing and even then the iphone still isnt recognised by the pc to restore, Is there any other way i can go about fixing this problem!!!!

You can try the steps recommended in the User Guide. If they don't work bring your phone into Apple for evaluation.

My first problem is that I have no apps on my iPod desktop. The second is that my battery died, and despite being able to charge it, it is unable to restart back up.

My first problem is that I have no apps on my iPod desktop. After using my computer to install something onto my iPod 5, it somehow disconnected. When i restarted the iPod, some apps (Safari, FaceTime, Game Center, App Store, iTunes Store, Camera, and some others disappeared. Apps like Flashlight and Jetpack Joyride which I had previousyl downloaded from the App Store were still there. I wanted to get the aforementioned apps back, so i decided to back-up my iPod to iTunes. The downloaded apps weren't able to be backed up ("authentication problems") but some apps like Tips, Video, iBooks, Reminders, Stocks, Settings, Voice Memos, were backed up. I then proceeded to factory reset the iPod, deleting everything and starting it as a new iPod. Once I finished this, I looked my desktop to see everything was gone, absolutely everything. I double-pressed the home button, showing Settings was open, but that's it. I opened settings and factory reset it again, this time choosing to restore from a backup. After doing this, I found the iPod looked the same as the last time i reset it - blank. If I scroll down the middle of the screen to bring up a search bar, I can find only the apps I backed up (Tips, Video, iBooks, Reminders, etc.) That is the first MAJOR problem. I was getting really frustrated, so I opened up iBooks and discovered I can download a could free books from the store, which was essentially the only thing I can use the iPod for. There were no videos in the Video app, and pressing the "Go to Store" button did absolutely nothing. No lag, it just ignored my touch. Once i found a few books, I decided to start reading. Eventually, i brought this iPod somewhere to read it, and didn't bring the charger with me. The battery died, and when i got home, tried charging it.
Which brings me to the second problem. A minute or so after I plugged in the charger into the dead iPod, the Apple logo came on. But the iPod never started up. The logo stayed there, getting dimmer after a minute, but no vanishing even after fully charging or pulling out the charging cord. It didn't leave even after hours, but by then the battery died again. If i press and hold the power button and the home button at the same time, the Apple logo disappears. But I can't get into recovery mode utilizing the volume buttons. If i hold the power button when the screen is blank, the Apple logo comes back. But the iPod cannot start up.
After everything was wiped, i was pretty angry. But I still had books to read, even if i couldn't do much else. Then the battery died, and it really wrecked me up. I feel so mad right now, although this actually happened about 4 days ago. The iPod being wiped happened about 3 days after the Christmas holidays began. This iPod also was not brand new, I bought it off a friend who had it for over a year, although it was in perfect condition (Obviously out of warranty.) I desperately need a solution to this HUGE problem. Due to personal reasons, I can't go to a Genius Bar or go to an Apple retailer in person, but communicating by E-mail is an option, as is instant messaging.

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.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

The missing apps could have been done by setting the Restrictions that can hid those apps. If the backup was made with those retrictions set the the Restrictions are also restored.
Thus, if you get it to work restore to factory settings/new iPod, not from backup

My ipod touch is frozen on a screen with the ipod logo and the usb charger cable...i cannot get rid of it...i let the battery die...i held the sleep button and the power buttons..anyone have any ideas?

my ipod touch is frozen... the screen has a picture of the itunes logo and a usb charger. I have held the sleep button and the power button to reset and i have let the battery die and started to recharge...niether worked. any ideas???

Try charing it to 50% at least.
If all else fails, try putting it in DFU mode. Connect it to iTunes, (iTunes may not detect the device, but that's ok) hold the power and home buttons down for 10 seconds, then release the power button but keep holding the home button until it goes into DFU mode. iTunes should detect it and ask for a restore.

My iPhone 5 battery died and will no longer turn on. What do I do?

Just got my new iPhone 5 two days ago. My battery died and I tried to charge it for the first time but nothing happens. It won't charge via USB or the wall plug. The only thing that happens is the picture of the phone with the arrow pointing to the battery comes on indicating that the phone needs to be plugged in. What do I do?

For how long did you try to charge the phone? If you've tried charging for hours with nothing happening, I would assume there is a fault with either the Lightning cable or the phone itself (possibly a battery fault) since you get the same whether you connect to the PC or external charger. If you can, make a Genius Bar appointment to have all aspects checked...either that or return to where you purchased the phone and have them check it out and replace it under warranty.
EDIT: Something to try is to verify that the lightning port on the phone (and the cable) is free of any dust/lint/gunk/whatever. Try blowing it out or use a soft brush to disloge/remove any foreign matter that could be stuck in the port.

I just got a MacBook Pro and I used Home Sharing to transfer my library from my PC. However, my PC's battery died in the middle of the process so only half of my music was transferred. The sharing option no longer shows up on the left. How do I fix this?

I just got a MacBook Pro and I used Home Sharing to transfer my library from my PC. However, my PC's battery died in the middle of the process so only half of my music was transferred. The sharing option no longer shows up on the left. Do I need to start completely over and delete the content in my new library to prevent duplicates or is there a way to continue the process?

This is the second macbook pro i have owned in the past two weeks. I am ready to return it for good if this is a chronic issue. Please help if you have had this same issue.

Try a SMC reset:

My 16b 3gs was working perfectly. The battery died and I plugged it in correctly to charge and it also neohook up to itunes for restore. It also had a little exclamation button that reads: IMEI:unknown and just below it read ICCID: Unknown. Nothing else

My 16gig ipone 3gs was working perfectly since it was replaced only a month or to prior. I was visiting with some friends around the ole pipe and low and behold the phone was completly dried of it's go juice. One we noticed I reached into the kitchen and plugged it in to the outlet.,,, The battery died and I plugged it in correctly to charge and it also said Emergency calls only in various foriegn languages. It also said to plug it into your itunes. All the while haviing no calling options to say the least. I followed the apple instructions perfectly when it said that there was a new version of itunes I should download first, prior to refreshing it. It went through all of the installing and so on then at the end you still get a useless phone that doesnt work. IMEI: unknown and ICCIC; unknown (both of which can be found by you on the box or on the sim card case. I completley removed the sim card and it worked in my hubbies 3g.   I tried several times and also AT&t had made sure the imei and iccic where correct. So I spent hours getting nowhere with this. Its new and nice and broken.. Im going to leave that Apple store with a brand new iphone 4 tomorrow. Simply b/c it is for my pain and suffering and for giving me a crappy refurbished phone. Fair is fair. So if you've found a way to fix great, but Im going to get that free iphone 4 xoxo toodllloooo

I presumed from your original post that you had to fork out another $3000 for a temporary replacement, and be without your original for 1 week, then have to return the temporary one. Not to mention all the postage etc. Now, just presuming that you would be happy to pay $200 to have it fixed without all that hassle. Obviously your not satisfied with the current option otherwise you wouldn't have posted the thread to begin with.

Battery dying faster than normal and I have been to the Apple Store and battery is fine

Is anyone else experiencing this? Both my iPad and my iPhone 5 started to have the battery die 2x faster after the latest upgrade. I have reset it without losing data and I am about to reset one of them back to original. Any one have any suggestions? I am thinking that one of my apps is trying to always load or search for wifi but not sure and don't know how to figure out which one it is.
I have been to the Apple store and they have checked my batteries and both are fine. The staff suggested that I let the battery die right down and completely charge it and then shut it down for a few seconds. so that the device is " clean" and then turn it back on but that didn't work at all.

You can poke around in the settings. There's a lot of stuff defaulted to on that you may not need. Such as notifications. Background app update, background app update. Try turning those off and see if that helps.

Brought a second hand ipod touch 4th gen, tried to restore it and the battery died now it will not charge or switch on

Hello everyone I brought a second hand ipod touch 4th gen and it all worked fab except it wouldn't let me put any new apps on it so my friend suggested I restore it which I did but while it was restoring the battery died. Now it doesn't seem to be charging and I have left it for ages through the laptop and tried it through a geniune apple plug in charger but its not working. When you plug in the cable to the laptop or plug the little grey apple comes up on the screen but only stays on for about 5 maybe 6 seconds. Does anyone have any suggestions? I have tried all the trouble shooting suggestions on apple but none of its worked, Shall we just bin it and learn from our mistakes.
Thank you to anyone who can help
