Macbook Pro shutting off when unplugged and at 80% battery? help!

I have an early 2011 MacBook Pro 15 in. that i got in May of 2011. When i unplug the power adapter it works fine, but at about 80% battery it shuts off. i go to turn it back on and it acts as if it is dead, i press the power button again and it turns on without problem (although the date and time at first is messed up). What is wrong? I recently had to get my hard drive replaced 2 months ago and it has been working fine until yesterday. What could be wrong and how do i fix it?

Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go.

  • MacBook Pro shuts off when unplugged.

    For the past week my MacBook charger has been not functioning correctly. It only charged my computer when it was the the right position. I figured there was a short in the wires and was just going to pick up a new one. Last night however, the charger stopped working completely. I tried moving it around for about an hour until i just gave up and figured there was no hope. As soon as i shut the MacBook though, the charger light came on, but again when i moved the wire too much, it turned off. As soon as the charger light turned off, so did my MacBook. And i thought it was weird since there was still about 20% battery life, and it turned back on fine, but the date got reset to the year 2000 and it made me put in my wifi info again, which has never happened. I shrugged it off and really didnt think much of it though until it happened again today. This afternoon i plugged my Macbook in and it was and the charger was working fine after i found the right position to put it in. I let it charge for a few hours while i was out, and when i got home i used my Macbook for about two hours before i decided to move the Mac, causing my charger to move and stop working. And my MacBook imediately shut off again, exactly how it did the night before. What is causing my Mac to do this? How do i fix it? Its about 2 years old and this is the first time anything like this has happened to it! Please help me, I'm not good with computers at all so i have no idea what to do. By the way i dont think its the battery since when i turn it back on it runs just fine without being plugged in. It only turns off when it has been charging and then stops.

    Borrow a friend's MagSafe Charger or try with the ones in the Apple Store. Sorry I wasn't clear from your post if you purchased a new charger yet.
    Also clean the contacts on the MagSafe port and the charger side.
    Apple recommends:
    "Remove debris gently with a cotton swab or a soft bristle toothbrush, which provide the strength, flexibility, and precision for this task. Be careful not to get any cotton fibers stuck in the pin receptacle. You may use isopropyl alcohol to aid in cleaning the connectors as well. Be sure the connectors are dry before using the computer or adapter after cleaning."

  • Macbook Pro shutting off when closed - Mountain Lion

    Just upgraded to Mountain Lion and now my macbook pro shuts off instead of sleeps everytime i close the screen and needs to be re-booted when screen is re-opened. Any one had the same issue and any known fixes?

    Check System Preferences --> Energy Saver and make sure you do not have the sleep sliders set to "Never".
    This may pertain to either or both Battery and/or Power Adapter tabs in System Preferences.

  • Why does my MacBook Pro shut off when I close it?

    When I am done using my MacBook Pro I would usually just shut the lid and the MacBook would then go into sleep mode. In other words later when I pick it up and open it the MacBook screen will light and I can begin using it immediately. However, lately when I shut the lid the MacBook will shut off completely and I will need to push the power button to turn it on again. I am curious as to what may be causing this? Any help or knowledge on this would be greatly appreciated! Thanks.

    Reset your SMC, as described here:

  • My MacBook Pro shuts off when it's unplugged

    My MacBook Pro keeps on shutting off after about a minute or two being unplugged. It works fine while it is connected to the power source but I can't figure out what is going on. Recently it shut off and when I turned it back on, it lost my network preferences and asked me about allowing mDNSresponder and other permissions. If anyone can help it would be greatly appreciated.

    You sound like you have a defective battery or a corrupt calibration file or a corrupt SMC data. Do the following:
    MacBook Air and MacBook Pro (Late 2008 and later)
    1. If the computer is on, turn it off by choosing Shutdown from the Apple () menu.
    2. Connect the power adapter to a working power source.
    3. On the built-in keyboard, press (left) Shift-Control-Option along with the power button once.
    4. Wait 5 seconds and press the power button to start the computer.                                                     
    Note: You must use the keys on the left side of the keyboard.
    If this changes things you may also want to recalibrate the battery
    (major Deja Vu here)
    Go to the Help menubar item in the Finder to learn how to calibrate the battery. It is a procedure that must be done a very specific way or it will not work at all. Print it out or write it down before proceeding.

  • Early 2011 Macbook Pro shuts off when charger unplugged.  Worked fine yesterday.

    Hi,
    I have an early 2011 Macbook Pro, which I purchased brand new; it's just over one year old.  Yesterday the laptop held a charge no problem for 6 hours or more.  Today, when I disconnect it from the charger it goes to sleep.  When I plug it back in and press the power button it wakes up, and I can use it.
    This cannot be a battery issue, since it was holding a charge without trouble yesterday.  Does this appear to be a serious issue?  My one year warranty expired 2 months ago yesterday, and I had forgot to purchase AppleCare.  Sigh.  It almost seems like surgically-planned obsolecense or punishment for not purchasing AppleCare.
    I would immensely appreciate any help/suggestions on this.
    Thanks.

    OK, in that case:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Mac OS X 10.6.8 Update Combo v1.1.
    Upgrading to Lion or Mountain Lion will not solve the problem.

  • MacBook Pro turns off when unplugged from outlet

    I have a MacBook Pro Intel Core Duo 2.26GHz
    2 days ago when I unplugged it from the wall it shut off. It has been doing this since even though the battery is fully charged.
    Once it is off I am able to turn it back on not plugged in and use it for the full length of the battery without problem.
    Anyone would know what would cause this? and how to fix it?
    Thx

    I would try the SMC reset.

  • MacBook Pro shuts down when unplugged

    I have a late 2008 MacBook Pro work computer. Here's the sequence of events:
    I fully charge the battery
    I unplug the Mac from the power cable
    The Mac immediately shuts down
    Before unplugging the Mac, I press the battery power indicator button and all lights are green. When I unplug the Mac I press the indicator button again and only one light is green.
    I've tried resetting the PRAM, SMC and even bought a new battery but the problem persists. Here is the System Information.
    How can I get my MacBook Pro to stay powered on when not plugged in?

    System Profiler shows you have 195 cycles on this batt and says "Service Battery" so I'm not sure if that's the old batt or you bought a used one, but either way, it looks like that batt is nearly dead. If you have a new/different batt, install it, give it a full charge, and post System Profiler info for that one.
    Also, have you tried  different power adapter and/or tried your power adapter on a different MBP?

  • My 3 year old macbook pro shuts off when it is trying to turn on

    when i turn on my macbook, it makes the startup sound, the logo comes. but then a loading bar appers and it starts loading, when it's about 1/5 of the way the loading bar  dissapears and it shuts down about 5 seconds after. the software it's using is mavericks (10.9.1)

    TheMikkelfl1,
    boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the  OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get to the login screen now?

  • Macbook Pro Shuts Down without Warning and with Full Battery

    I have been having a problem with my Macbook Pro, where it will shut down completely even though the battery is full.
    It is a fairly new battery, because I had it replaced back last fall. When it shuts down, my first instinct is to try and turn it back on. When I do this, it starts up normally, goes to the white screen, but then shuts down again...
    However, when I wait about a half hour and try turning it on again, it will boot up normally. It also works fine when plugged in.

  • My MacBook Pro shuts down when unplugged, even though fully charged. why?

    I keep my computer plugged in 99% of the time, but when I use it unplugged, it only works for a couple of minutes before it shuts down & won't come back on until I plug it back in. When I do, the battery is above 90% charged. Why does it shut down?

  • 2008 Unibody MacBook Pro shuts down when lid closed while on Battery

    Hello,
    I did some google searches, but could not find anything that was exactly my issue. I have a 2008 MBP unibody. If the MBP is on battery only and I close the lid, the notebook shuts down completely. This is even when the battery is fully charged. However if while plugged in and I do the same, the computer "sleeps" as advertised. I have reset both the SMC and PRAM to no avail. The main thing that bothers me is it seems like when this happens on battery, its almost as if the computer is getting a hard shut down. The machine acts as if the battery was pulled while the lid was closed and this is obviously not good for the hardware or sofware. Any help is greatly appreciated!
    Thanks
    Keith

    I forgot to add that when the lid is closed it doesnt shut down straight away. The LED on the front pulses and for a good 10-15 mins it does sleep and wake. However any time longer and it does its hard shut down deal.

  • Issues With MacBook Pro Shutting Off

    I have been having troubles the past couple of days with my MacBook Pro shutting off when running on battery power.
    MacBook Pro OSX 10.4.11. 2.16 Intel Core Duo. 1 G Ram.
    I will have plenty of battery charge and then "poof", computer just goes black and has no power. It does turn back on, but gets annoying. Everything runs fine when plugged into the wall.
    Anyone have any ideas of what may be causing this?
    Thanks.

    How old is your machine? This sort of thing is covered under warranty (or apple car). I got a new one about a year ago that way. Apple WILL ask for number of charge cycles. Believe it or not, high numbers can be good because it says that you have actually been using the battery and it's not just dead from sitting unused.
    It sounds like you have a dead cell. Your battery is separated into several compartments. Your charge looks fine until that cell is actually needed. At that point, CLUNK. Nothing works.

  • Macbook Pro shut off and won't turn on or charge?

    I purchased my Macbook Pro August 1st 2012 at Best Buy and in April it shut off for no reason and it wouldn't charge. Apple replaced the battery cable and my Macbook worked for a couple of weeks, then in May same thing happened and Apple replaced the MLB, a couple days later the same thing happens and Apple replaces the Magsafe board with cable. Then a few days later specific keys on the keyboard stop working and Apple replaces the topcase with keyboard. Now 120 days later my Macbook Pro shuts off and won't charge for the 4th time. My Macbook is now out of warranty but I don't think I should pay since this is the 4th time my MacBook Pro shuts off for no reason and won't charge. Yes I already tried reseting the smc, still didn't work. What could be causing this and is there anyway Apple will cover this since is the 4th time it shuts off for no reason?

    Call Apple Customer relation and explain your situation. Have your receipts for the work that was already preformed on it and ask them to replace it with a new unit.
