MacBook Pro turns off intermittently.

I have a 2008 MacBook Pro.  Every few days the unit turns off while I am using it.  I have to hold the start button down 4-5 seconds to restart it.  Any suggestions as to the problem?
Thanks,
Rayhy1

I am also experiencing this problem. Has anyone solved it yet?

  • MacBook Pro turned off on its own and now won't turn back on.

    MacBook Pro turned off on its own and now won't turn back on.  Battery had 41% just before this happened and green indicator on power cord is showing, so it seems like it's charging.  What should I do?

    The led on the power adapter should be amber if it is charging.  Green just indicates that it is supplying power to the MBP.
    Try a SMC reset:

  • I wanted to calibrate the battery my new macbook pro turns off

    You should perform this procedure when you first use your computer? is this true? new macbook pro on may 11 2010 what happed was today on may 22 2010 i wanted to calibrate the battery my new macbook pro turns off when it runs out of battery. 3 times Typically, when macs run out of battery, they go into sleep mode. However mine skips this completely and just turns off. WHY? does this mean the battery is bad?
    Resetting the PRAM (http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html) fixed the problem in my case. then i did the calibrate the battery again this time it went to sleep not shut down i did this 3 more times why?
    the 3 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010

    the 9 more 4 in 10.6.4 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010 but if it happens again you should try
    i hate to do this reinstalling the OS, if this do not work also, then you should call apple, or take your MBP to an apple store. on june 24 2010 i am going to talk to spence about this. so what do i do now? this happed on june 16 2010 4 more times
    without entering SafeSleep. only one time it worked on 10.6.4

    This is a current sensor on the power bus. This seems consistent with your symptoms.
    A faulty sensor on the logic board means  the board has to be replaced,  take in for repair:

    macbook pro turns off when i unpliug

    You either need to plug in your charger and if that isn't working if your machine is less than a year old take it in to your nearst Apple Store and let them deal with it. Or if you are out of warrantee you will need to get a new battery for your Mac

  • MacBook Pro turns off during boot?

    This is kind of a long story.
    I have a 13-inch, Mid-2010 MacBook Pro running OS X Mavericks. I was using it near a bathtub, when a moderate amount of water spilled onto the keyboard. I immediately dabbed out most of it, and put it upside down for some time. It was running then, with all the keys and trackpad working fine. t turned it off, and tired turning it on after half an hour. Nothing. I decided to keep it switched off for 7 days, during which I would open the lid every now and then to find vapor on the screen from the keyboard which I would wipe and close again. I turned it on when there was no vapor spotted for 3 days. I plugged it in after 7 days, to see that the battery status indicator was erratic. It turned on with a sound from the SuperDrive (the usual click). There was no startup chime. A few minutes later, it turned off. I decided to reset the PRAM and SMC, and I realized that I can get to my account window successfully (and type a 22 letter password) as long as I keep any key pressed throughout bootup (option, command key, etc). I have tried many times, but it just turns off with a "nik" sound. I haven't backed up, and I have about 270 GB of important data stored that I CANNOT lose.
    If it helps, it's 250GB drive crashed in December but it was replaced with a 500 GB and has been running smooth until this.
    Please help me! Any advice at all is extremely appreciated. Thank you!

    Take the HDD out of the MBP and install it in an enclosure.  Connect it to another Mac and see if you have access to the HDD.  If so, copy what ever files that are important to you to another HDD.
    Then you can take the MBP to an Apple store genius bar for a FREE evaluation.  Prepare your self  for unfavorable news.
    Ciao.

  • MacBook Pro turns off in seconds.

    My wife has a 2008 MacBook Pro and when she turned it off last night it's decided to not turn on again. If I just push the power button it stays on for about three seconds, then shuts off. However if I hold the power button down and don't let go, it last about 6 seconds before shutting off. Nothing ever shows up on the screen. I've tried it with the battery in, with the battery removed, and with both the battery and it plugged in. Any ideas? My fear is its bit the big one. Thanks in advance!

    Take it to an Apple store or AASP.

  • MacBook Pro Turns off Randomly Only when logged in OSX 10.8.2

    Hi,
    I have a 2010 Macbook pro with Mountain Lion 10.8.2. For a couple of weeks now, when its not plugged in to AC it turns off randomly, not at any specific battery%.
    Things I have tried already that were not helpful:
    - System profiler battery: 374 cycles, Battery Status: Normal
    - SMC reset
    - Clean install of Mountain Lion without any Migraion of old System files (wanted to do this anyways before the problem arose)
    - Its does not seem to be a heating issue, has happened at low temperatures
    What I have noticed is that if I either run the diagnostics at startup or enter to recovery mode, I can run the battery all the way to 0% (lasts a while) and this random swtiching off doesn't occur. It only happens when I am logged in to OSX. This makes me think its not a battery issue either.
    Any help would be great.
    Thanks!

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • My MacBook Pro turns off

    It appears the window as if I press the ON/OFF button, if I don't touch anything then, the computer turns off; I discover that if I am working constantly nothing of this happens.
    I wish someone could answer me and give me ideas.
    Than you

    Note the exact time the event occurs, and then check your system logs in your Console application for clues to the cause.

  • Why does my macbook pro turn off randomly?

    So i recently had to get a new harddrive in my macbook pro 13 inch 2012 model. It's been constantly shutting off in the middle of me doing anything! I have no idea what it could be! Also, when I'm on the internet, it is unbearably lagey and slow. I just want to know the situation and what it may be. I no longer am on apple care or have a warrenty because i forgot to renew it. I have the updated version of mavericks and i was thinking that may be it. Thanks!

    Hi eightyoctane,
    If you are having intermittent power issues with your Thunderbolt display, you may want to make sure that all available updates have been installed, as outlined in the following articles for somewhat similar issues:
