Why does my Mac randomly keep shutting off?

I've had it for about 6 years now and always have to have it plugged in because the battery is swollen and won't fit for the lid to stay shut. Now recently it's been randomly shutting off and have to turn it on again. Is it dying or it simply not getting enough sleep?

Hi av2557 and welcome to Apple Support Communities,
First stop using that battery and stop charging it!

There was a recall of these batteries but that has ended.

    Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say.  It will shut down if it gets too hot, but that's not a normal occurrence.  I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
    First thing I would try to do is reset the SMC.  If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
    If a fresh system doesn't help, you'll need to get it checked out by Apple.
    Edit: Oh, and sig is absolutely right...  please don't post in all caps!  It's very irritating.

  • Why does my iMac display keep shutting off?  Computer still running in the background.  I've tried unplugging and restarting, to no avail.

    Why does my iMac display keep shutting off?  Computer still running in the background.  I've tried unplugging and restarting, to no avail.    The computer is well out of warranty - about 7-8 years old, running 10.6.8

    Checked.... the settings had not been inadvertently changed, but I did move the scroll and reset them back to the original.   Hasn't shut off again.... yet.   Will re-post with follow-up one way or the other.   Thanks.

  • Why does my wireless keyboard keep shutting off?

    Why does my wireless keyboard keep shutting off?
    It is not the batteries.

    More experience leads me to believe the problem is with the new iMac.  If I get the network going by turning AirPort Extreme power off, then on, I see a good signal at my iMac. Experience shows the network drops off after several hours. But yesterday I turned the iMac off, and the network remainded up (I could see it on my iPhone and iPad) throughout the night.  That's the first time that has happened since I got the new iMac.  Never had this issue with the old machine. I transferred all file to the new machine from a Time Machine backup that was up-to-date.  Am working with Apple support. They had me do a re-boot of the AirPort and will call back tomorrow AM to learn it did not solve the problem, but turning off the iMac does.  Darn.

  • Why does my iPad mini keep shutting off every two seconds?

    Why does my iPad mini keep shutting off every two seconds?

    I doubt that anyone here can answer that question with any validity...
    That being said, try to reset the device:
    *Device reset*
    Device Reset (won't affect settings/data/music/apps/etc)
    1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
    2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
    3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

    Not much to work with here...
    How about more info so a diagnosis and help can be formulated? Mac model (size), RAM, OS version, age, battery status? What are you doing when it happens? How often? And if you want to be really abundant, pertinent logfiles?

  • Why does my MacBook Pro keep shutting off while I'm using it with full battery?

    My Battery is 100% full and it keeps shutting off randomly, how can I fix this?

    This is something you should log. Whenever your machine shuts off randomly, make a note of the time and what you were doing on your machine at the time. You may find that the shut downs aren't random at all. I had a similar problem with "random" shutdowns, and discovered that there was a power supply issue.
    Please post here with your results.

  • Why does my NEW ipod keep shutting off in less than 30 seconds of play time

    Rcv'd ipod at Christmas; was setup in spanish when I first turned on & thought that was weird; had issues trying to download version 10 of itunes but after two days it finally went through successfully; charged for two days; used for first time today and it keeps shutting off after 30-90 seconds of playtime; is this a common issue or do I need to send back?

    No, push the headphones firmly all the way in. The headphone jack on new nanos is very tight, make sure the plastic on the headset jack is flush with the body of the nano.

  • Why does my iPhone 4s keep shutting off when it gets to 15% battery life?

    It just shuts off, and once I put it on the charger, it will turn on with 18% or more.  This has been happening for the past few days now, and I don't know what's going on o_O

    Have you been doing the recommended running the iPhone until it powers down then recharging to 100% once a month or so, in order to keep the charge readout calibrated?
