My MAC Pro shuts down when the battery still have 50 minutes life.

My MAC Pro shuts down when the battery still has 52 minutes life without any warning. Does anyone have this problem? BTW, it is less than one year old.

You must have a MacBookPro, right? MacPro's are big desktop models.
Try the MacBookPro battery forum or their Usage forum.

My iPhone shuts down when the battery still has about 30%

When I then try to restart, it won't, but just show the red low battery icon with the charger cable telling me to recharge first. When I then plug in the charger, it shows maybe still 27% and starts to charge. Before this problem occured my iPhone went down to 1% or so and only THEN shut down automatically.
Have reset my iPhone and "recalibrated" the battery (total discharge followed by a full charge to 100% with original iPhone charger). Problem persists.
Thanks for any help!

Sorry, iPhone 4S, but IOS 7 something.

My iPhone automatically shuts down when the battery reaches 50%. How can I resolve it?

My iPhone 4 iOS 7.0 automatically shuts down when the battery charge reaches 50%. Is it a battery problem or is it the phone?

Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks.

My Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks on the left side. I am running Lion. How do I get this to charge and turn on? Thanks

If your model Macbook Pro is the calibrating model, let the battery calibrate.
If not, and are still under warrant or have Apple Care, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Why mac pro shuts down when idle, even when charging ipad?

why mac pro shuts off when idle, even while charging ipad?

Thanks for replying. I have a macbook Pro. In my energy saver, I ticked the following: put hard disk to sleep when possible, wake for network access and automatically reduce brightness before display goes to sleep. My boyfriend has the same settings but I can charge my ipad with no interruption on his macbook Pro and it doesn't shuts off when idle. Thanks for your help

Why is my phone shutting down when the battery is @ 94% doing anything with it? Is the recent upgrade a chance to get us to buy and Iphone 4?

My I phone 3ga 16gb shuts down when I open any app and surf any webpage unless plugged in to the charger. I have 94% battery and as long as I don't do anything with the phone except answer it when I get a call it will stay on. I recently upgraded it to the 4.3.5 os and was wondering if that is my problem? if it is how do I get it back to an older operating system?

Highly unlikely that 4.3.5 itself is the problem as there would be millions with the same problem... there are not.
Restore your 3GS from your backup. If still a problem, restore as new, i.e. without your backup. One of those will most likely solve your problem. If not, you may have a defective battery.

New Mac Pro shuts down when I put it to sleep?

I go to click my mouse of keyboard and nothing happens. I click the power button the back lights up and turns on as if it were off, what gives? This is brand new 64gb ram, 12 core, didn't even do a migration so it's all new stuff on here.

Hello Chief Sneed,
It sounds like your computer is going to sleep but when you later go to wake it up it will not turn on unless you press the power button and it looks to have shutdown at some point. I recommend checking to see if the computer is scheduled to shutdown at a certain time with the following article:
OS X Mavericks: Schedule your Mac to shut down or go to sleep automatically
http://support.apple.com/kb/PH13914
Schedule your Mac to turn on, turn off, go to sleep, or wake from sleep at specified times. You might do this if you want to be sure your Mac turns off when you aren’t working and turns on before you come to work.
Choose Apple menu > System Preferences, then click Energy Saver.
Click Schedule, then select the options you want to use.
To schedule a startup or wake time for your Mac, select the “Start up or wake” checkbox. Choose a day or group of days from the pop-up menu, then enter a time.
To schedule a shutdown, sleep, or restart time for your Mac, select the bottom checkbox and choose the appropriate option from the pop-up menu. Choose a day or group of days from the pop-up menu, then enter a time.
Thank you for using Apple Support Communities.
Take care,

Mac Pro shuts down when I move case

Whenever I turn on my Mac Pro it sometimes randomly shuts down and when I move it, it all most certainly shuts down. I've tried a smc reset and a pram reset but when moving it, it still turns off. need help thanks :)

Is the power cord plug pushed in all the way at the back of the computer?

Mac Pro Shuts down when sleep selected

My Mac Pro (Quad 2.8 - Early 2008) Locks up or powers off when I try to sleep the machine. This also happens during an automatic sleep, which I have since disabled. I got assistance from online tech support. We tried just about every routine procedure, but nothing helps.
The strange part is once the machine is powered off I have to wait about 20 minutes before I can turn it back on. Every attempt using the power button fails. So I have to let it sit for a while. I thought it was over heating, but the fans are working fine and very quiet.
Help needed.

I think it gets a little bit mental when we start talking about nano volts in power supplies. If these machines need a pristine supply to operate, then how have Apple managed all these years? This is a problem with the machines themselves (and even if it IS caused by domestic power supply, then the fault is still with the machines, as most folk don't live in these hermetically sealed biospheres that seem to be recommended). Mine just started doing the same thing. Other machines (Mac Pros, iMac and MacBook) are fine. Also odd that so many domestic power supplies across the world cause different people with the same machine to have the same fault.
I suspect it's a dodgy card. Perhaps corrupted system preferences, but given the number of folk with the problem (why does that always get ignored in favour of assuming all incidents are separate?), I suspect a hardware issue.
I've tried the 'unplugging everything' routine, but the fault returns. I'll try the 'unplugging everything for a day' routine - as mooted - and see what's what. But I suspect a trip to Apple is on the cards. I'm running Disk Warrior at present, to what avail I'm unsure, but I'll update my progress here.

My iPhone shuts down when the battery is still 18%, what's wrong?

Sooo my phone started to shut down sooner and sooner (5% - 9% and now 18%).
I usually charge it every night and in the morning it says 100%.
Also, the battery percentage drops a lot in a short amount of time.
I don't use my phone excessively or anything so I don't understand why it would just shut down like this.
- iPhone 4s 16GB with iOS 6.1.3
Please help.

Check your energy savings. The settings may be set to something. If that does not work, try resetting your PMU.

Mac pro shuts down suddenly power light still on wont start

just hadd new logic board as apple thought it was that causing sudden shut downs

Well, why not put your hardware profile for all to see, and whether Apple OEM or upgraded graphic card; whether Apple Hardware Test has any useful information. Even running Memtest on your RAM.
Monitor the internal temps of everything you can (video we are expected to fly blind as there is no useful GPU-Z utility).
If anything, boosting the default fan speeds by 300 rpm won't hurt, and commonly done.
That model had a EFI firmware update to deal with trouble crashing on wake from sleep and inrush current, fwiw even though you aren't sleeping the system.
An SMC Reset (the longer the better) and zap pram/nvram are probably one line of troubleshooting. But I wouldn't wait to repair your drives with Disk Warrior from an emergency backup/clone boot drive as any such freeze can only just lead to more problems than originally.

MacBook Pro shuts down when i close the lid

Hey,
My MacBook Pro shuts down when i close the lid.
It started to do this one or two times, but now it is every time.
I have the latest battery update, so this should not be the issue here..
Any sugestions??
I have started to suspect the it might be some faulty conecctions or somthing..

If it's unable to go into the proper sleep state for some reason then it will do that.
Run /Utilities/Console and click 'All Messages' top left then close the lid, wait a minute then open it again - if it's shut down then reboot and open Console again and check the latest log lines looking for 'sleepimage' - it should give you an indication of what happened/didn't. If you're not sure what it all means post _just those lines_ here.
