Early 2011 MacBook Pro shutting off all by itself

Early 2011 MacBook Pro 11" shutting off all by itself recently.
I had the logic board replaced 11 months ago because it started to shut off more and more until it refused to boot up again.
Now I am going through the same problem. Is this common?

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.

  • 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.

  • My 2011 macbook pro shuts off all the time!

    My 2011 macbook pro started shutting off with increasing frequency. It was very frustrating. I installed mavericks and now it seems to shut off about every 5 minutes! Only if I'm working, if it's streaming it seems fine. I think it would be impossible to actually get work done. I've read many others are having the same problem and taking theirs in for costly ineffective repairs. I can't afford to pay Apple to "chase it's tail".I may just go PC. Has anyone found out what the issue really is and how to fix it?

  • My Early 2011 Macbook Pro Continues to shut off at random

    I own an early 2011 Macbook Pro, 4GB RAM, intel 3000 384mb graphics, 250gb SATA hd. I now have OS X 10.8.2 and my macbook randomly shuts off and its not just once or twice a day. It is more along the lines of over 20 times a day. Can somebody give me some advice to resolve this issue? I used mackeeper and ran every scan and I went to disk utility and repaired the drive. I don't know what else i could possibly do. This issue is making me wish i never bought this mac. The macbook is great and all but now i can't even use it because it shuts off at random. I can't enjoy the macbook if i have to use it in fear that it will shut off at any moment. Can someone please help me with this issue quickly?

    If you have Apple Care or are still under warranty, 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.

  • My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all.

    My early 2011 Macbook Pro on start up has wifi, but drops it soon after and never comes back, AHT shows nothing wrong. Multiple wifi's tried and same on all.  I have also re-installed OSX from scratch and still happens.

    I have the same problem. I have a white macbook 2010, with mavericks os. I just found my mac not powering on and then I tried to run it on safe mode by holding the shift button but it will turn off seconds after I let go of the shift button. I am able to access the desktop and use it while holding the shift button the whole time. It's a bit slower than before but I figured maybe it's because of holding down shift button.
    I went to the Apple Store to have them look at my mac and I was told it's a failed hard disk. I wasn't told why he was able to conclude that a failed hard disk is causing the problem, I was just told to get a replacement. But the thing is when I ran Disk Utility it says, "disk appears to be okay." So I also feel like it's possible it's not a hard disk issue because it's also the first time it happened. My mac was working perfectly fine before all this.
    Do you know anything else that could cause this problem? Were you able to find out what's wrong?
    Thanks.

  • Early 2011 MacBook Pro- The thermal paste discussion.

    It is my goal to clear up the questions and concerns Apple customers have been having regarding heat or fan related concerns with Early 2011 MacBook Pros. If your MacBook Pro was produced within the last few months the thermal issue has been resolved and it will likely not be in issue for you. If you are still wondering if your computer is effected or what the real issue is keep reading.
    The MacBook Cools itself by 2 main methods: active and passive. The active cooling is via a fan that blows air through a heatsync and into a tube called a heat pipe which leads to the back of the computer where the hot air is discharged through a vent at the bottom of the screen behind the hinge. The fan lowers the air pressure inside the case causing outside air is drawn in the case, displacing the hot air inside and helping to cool the other components.
    The computer uses passive cooling to remove the residual heat from the processor which comes mostly in the form of radiant heat. Passive cooling is also used to cool the other components of the computer (memory, disk drives, battery etc). Passive cooling works by conductive heat transfer ie. syncing to the case of the computer. Some of the heat then is radiated. Some of it is transferred from the outside of the case via convective cooling; the foot pads on the bottom cover are designed to raise it up just enough to allow air underneath for convection to occur. (Convection is the process in which hot air to rises and is displaced by cooler air.) The rest of the heat from the bottom cover is absorbed by whatever surface you have the computer on.
    The processor will not sync to the case very much if the board is assembled properly however the other components of the computer will, requiring the case to be in open air to allow for passive cooling to take place.
    If you have some sort of covering such as a plastic snap on case it will likely interfere with passive cooling in all of it's 3 of it forms, this will cause the computer to be abnormally hot. I recently saw someone in the Apple store with a MacBook Air experiencing abnormal heating due to a plastic snap case so this particular problem is not unique to MacBook Pros and it is not the cause of the issue being discussed here. I do not recommend the use or anything that covers the computer while it is running with the exception of something that covers the back of the display panel only. If you are worried about your computer getting damaged go and buy a laptop insurance policy from Worth Ave group. The insurance does not cover cosmetic damage or misplaced items but will cover accidental damage including spills. This insurance also covers theft, vandalism and natural disasters, is quite inexpensive and the claims process and deductible  is similar to most phone insurance plans (which they also offer).
    User induced overheating can also occur when the computer is placed on an improper surface such as a couch cushion, car seat, bed, pillow etc. Doing this can interfere with both passive and active cooling.
    As I mentioned earlier In all likelihood if your computer was produced after May it is not affected. I personally have been in posession of 3 MacBook Pros, one produced before May which had the problem, one after which had no problems and one produced more recently that has mind blowing thermal performance way beyond all of my expectations.
    So the question at this point is exactly what is the problem, how can it be diagnosed and how can it be rectified.
    After extensive research and testing I have determined the issue to be related to improper application thermal paste. I involuntarily became involved in this pursuit as a result of the problems I was experiencing and I did not initially come at from an objective viewpoint but rather one of cautious skepticism. I had anticipated before purchasing my computer that there may be a thermal issue. This anticipaion came as a result of reading an article on ifixit.com about the disassembly of the brand new early 2011 MacBook Pro. When the technician performing the disassembly removed the main heat sync he expressed concern about how much much thermal paste was present, expressing that it seemed excessive. This lead the technician to question wether or not it would cause heating problems.
    Proper application of thermal paste is critical to the functionality of the active cooling system and when applied improperly will not properly transfer the heat to the heat-sync which in turn gets cooled by the fan. Proper application of thermal paste insures the heat is removed from the case as efficiently as possible. Doing this both reduces the speed at which the fan needs to run in a lot of situations and prevents too much heat from the processor needing to be cooled by passive means. If is is not applied properly it will eventually lead to overheating of the case as well as the other components of the computer. This can cause damage firstly to the computer's battery and can also significantly shorten the life computer. (Or any other kind of electronic device for that matter.)
    The problem can be diagnosed by testing the computer using a program called System Load or any other software that will put your computers proscessor use up to its maximum and keep it there indefinitely. Placing full load on your GPU at the same time during the test is also recommended. Keep in mind, if you are using your computer the fan will spin up if needed for additional cooling. You should expect the fan go up to its maximum speed during the test, it is not in of itself an indication of a negative result. Make sure to have the computer plugged in, fully charged and on a proper surface. A desk or other flat surface should be fine. Exceptions would include the top of a refrigerator since it has insulation just underneath the metal exterior or any surface that is heated by any means such as a dryer or other appliance.
    (The temps to follow are in ºF)
    Run the test for up to 1 hour. If the case of the computer breaks 93 degrees your unit is likely affected. Expect the unit to even possibly reach temps approaching and exceeding 100º, if this happens immediately abort the test. Also look for the processor temp shooting up to around 180 in the first 30 seconds and the fan spinning up right away. Typically on a properly functioning unit the temperature of the case will end up being somewhere in the neighborhood of 88-91º. If this test is preformed in a room with a normal ambient room temperature of about 68 degrees. Even after an hour the case of the computer should not be significantly hot, just warm to the touch. On a normally operating unit the fan will start to kick in within 90 seconds or so and may not reach full speed even after several minuets.
    At one point the case of my computer actually reached 95º during normal web browsing.
    This is a problem that I have had successfully corrected twice by reapplication of thermal paste. The first time was on a machine produced prior to may and the second was after a logic board was replaced at the repair depot. (I suspect the inventory turnover is lower for boards than whole computers resulting in a board from the initial production run being installed in my computer.)
    If you forget everything I just wrote remember this. #1 if you are using your computer hard enough the fan will end up running at high speed at some point. #2 This problem is not in any way related to the design of the MacBook Pro, or its use/application. #3 This mostly not a problem of the CPU being too hot; these Sandy Bridge CPUs are rated for 212ºf and will routinely be in the neighborhood of 200º, this is hotter than other chips but well within design limits. #4 I have done everything in my power to make sure that this problem has been corrected and I have every logical and evidenced based reason to believe it has been resolved in machines produced after may. #5 This is not an Apple acknolidged issue. Technicians will tell you that there is no problem because these higher temps are normal and within operating limits and if they weren't the machine would shut itself off. (This is a bit extreme; just like a lot of other devices such as electronics, toaster ovens and space heaters with thermal overload protection this automatic shutoff is intended to occur when damage or risk of fire is imminent because the device is WAY outside of normal operating paramaters.) They will also not tell you when asked what these limits are, that they know what they are or in some cases that such figures they even exsist.
    I stake my personal and professional reputation on the accuracy of my findings, it is my job as a private consultant to help my clients to resolve complicated and expensive issues just like this one.
    Bottom line if you are having a problem and Apple won't fix it on warranty don't ditch your machine, just pay to have it done yourself. In most cases you can pay have it done at the Apple store. It will probably cost you less than 100.00, and it will not void your warranty as long as the work is done by Apple certified technician. It will be well worth it; after all in spite of this MacBook Pro's are hands down the best portable computers on the market, with an industry leading warranty and support to back it up. On it's worst day Apple's service and support is better than any computer/ consumer electronics company, even on its best day.
    I hope this helps to clarify this issue! I also hope it will help anyone affected to resolve the problem instead of resorting to a refund and settling for something else.

    hello all
    you can try this:
    Go to system preferences > settings > built in display >  see bottom of window.
    check "show mirroring options in the menu bar when available". then click "airplay display" > and select your device.
    That's what happened to my MBP - 15-inch, Late 2011 model.

  • 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.

  • Airplay mirroring on early 2011 macbook pro not mirroring

    First, here's what I have:
    Early 2011 macbook pro (identifier 8,3) with 2.2 Intel Core i7 processor connected over Wifi on 2.4 Ghz channel.
    OSX 10.8 Mountain Lion
    Apple TV 3 (fully up to date)
    The stats I've read say airplay mirroring should work fine.  I can connect both machines just fine. I can stream movies just fine. I can send music just fine.  I just cannot mirror my desktop.  I have the icons, a connection is made, but all that shows is a blank screen. I've adjusted the resolutions with no luck.  I've shut down and rebooted both machines with no luck...
    Any solutions or do I have to count my losses with Apple Airplay and spend more money on a 3rd party alternative (AirParrot)?

    Hi eoinodonnell,
    The problem was resolved, but I have the worst answer... it just started working, and has remained reliable since.  I never found out exactly what fixed it, but I would try these things:
    1) Try a factory reset on the Apple TV, and make sure your Macbook pro has all the latest updates.
    2) Try to repair disk permissions (better to do it from disk utility from boot menu) and reboot your macbook.
    3) Backup your files and do a fresh install of OSX.
    I know I performed all these tasks, and possibly more, but something along the way did fix the problem. 
    I hope something here works!  If so, please let me know what did it.

  • MacBook Pro shuts off after attempting to boot

    So I may have accidentally deleted a file that I thought was a temp connected to another file. I stopped the deletion when I realized it was a large file. I restarted my computer and when it starts to boot, and during the spinning wheel, it shuts off. I do have a recent back up of my system, though I can't start it to do anything.
    Can anyone give me some ideas of how I might be able to correct?
    I have an early 2011 MacBook Pro.
    Thanks.

    Boot to the Mac OS X Utilities Recovery HD system. At startup hold down the Command + r key to access that system. then select Reinstall Mac OS X. A fresh copy of Lion will be downloaded from the internet and installed on your Mac. Doing this so called Over the Top reinstall should not affect any other files on your Mac other than to replace the file/s you deleted.
    You can also use that Mac Utilities boot to restore your system from your Time Machine backup which might be the best thing to do. Have the TM backup drive connected before you start the Recovery boot process.

  • How can I connect my Early 2011" Macbook Pro 13" inch, with a generic Mini Display Port to HDMI connector, to a LG 32LD340 LCD TV, using Mountain Lion 10.8.2?

    I have an Early 2011" macbook pro 13 inch (core i5 2.3ghz 4gb ram 320hdd) with Mountain Lion 10.8.2, and I want to connect it via Mini DP to HDMI connector, and a HDMI cable to a LCD TV LG 32LD340. When I had Lion OS, I had no problems at all.

    If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

  • Early 2011 MacBook Pro incredibly slow after installing Mavericks

    I'm really hoping someone can help me out. As per the subject line, I installed Mavericks on day one (and learned my lesson!).
    Since installing Mavericks my MacBook Pro runs incredibly slow. If I open the Mail App and Safari - it almost grinds to a halt. I have the "Memory Clean" App which I now have to run constantly (it appears to help a little) and I try to only launch one app at a time where possible, but it's not really pratical.
    As an aside, my MacBook ran really well with Mountain Lion, so there's little doubt to my mind that Mavericks is the culprit.
    I'd be eternally grateful for any help & advice :-)
    I spotted other people advise running EtreCheck, here are my results:

    CleanMyMac is probably your problem.
    CleanMyMac is crapware.
    Crapware is anything that purports to "optimize",  "clean", "accelerate", "monitor", or "protect" your Mac. These apps are unnecessary, poorly written, overpriced (if they were free, they'd still be overpriced), and harmful. The people who sell this stuff know this, but they keep selling it because people keep buying it. They can damage your OS and be difficult to uninstall.
    I would try to uninstall it, but if that fails, you may have to erase your HD and do a clean install.

  • If I buy an external monitor (with a res of 2560x1440) will my early 2011 MacBook Pro work ok? And will it be utilising the monitors full res or not?

    Hi,
    I have an early 2011 MacBook Pro. I use Premiere Pro CS5 to video edit on. It's fine but when it comes to grading it's nearly impossible on such a small screen.
    I'd like to buy a 27inch external monitor (Asus, Samsung, Dell, whatever - haven't decided yet) for when I'm editing at work (which is most days). My query is regarding the resolutions. Obviously my MacBook Pro displays a resolution of 1280x800, so if I buy a monitor with a resolution of 2560x1440 for example, what gets displayed?
    And also does the connecting cable make any difference? For example, if I'm connecting by Thunderbolt out to HDMI, then an HDMI to HDMI cable to the external monitor, what happens then? Or should I be using a Mini Display Port to Display Port connecting lead?
    I guess all I really want to know is, will it work? But also, am I wasting my money buying an external monitor with a 2560x1440 resolution? Should I just go for one that's the same res at my MacBook Pro?
    I've never really understood how these things all work!
    Thanks in advance for anyones help.
    Regards,
    Phil   

    I think it will work.  You would need a mini displayport to (single link) DVI adapter to hook up that monitor.
    Not sure what kind of problems you had with the ViewSonic but I'm guessing the Dell is probably a better monitor anyhow.

  • My early 2011 MacBook Pro says battery not detected and does not work with a new battery either. Works only with the charger plugged in.

    About a year back i had replaced the MLB of my early 2011 macbook pro and it was all working fine. A month back my battery went dead saying "Battery Not Detected". I went to Ample technologies, Bangalore, India and gave it for diagnosis. Ample technologies are the authorized Apple support service in Bangalore, India. After 3 days and no phone calls they email me that "They feel that the MLB MIGHT be the problem and they want to test it by replacing the MLB and i have to pay for their testing". I had already spent 40k indian rupees ($700) less than a year back to replace an MLB and now they want to replace it again at the cost of 43k ($750) indian rupees. I have no idea what to do now. Spending 80k indian rupees ($1400) in less than a year to replace the MLB twice sounds unfair to me. Can someone help me out here ? Is there a valid warranty period applicable , since i have changed the MLB a year back ?

    short of doing a SMC reset, you maybe at their mercy.

  • Early 2011 Macbook Pro GPU

    I know this question has been asked before. My problem is similar to what is mentioned here but I hope someone can explain the error log attached below and hopefully I'm able to find a DIY solution without much cost.
    I'm using a early 2011 MBP with Yosemite installed. Not too long ago, I manually upgraded my hard disk to a OWC SSD.
    Recently my MBP screen went into white blank screen AGAIN while I was working on a python script which crawls the web with about 10 threads. I used to run this same script without *much* problems before yosemite (ie: i encounter the same problem with Mavericks but not so frequent. I never install mountain Lion before so I can't comment on that. I came from Snow Leopard to Maverick and Yosemite). Other times, my MBP will go into the same white blank screen while doing other misc stuff and this usually doesn't involved me watching any HD video.
    A couple of solutions that get my MBP up and running are:
    1) I hard shutdown and bootup my MBP. After the apple logo it freezes at the white blank screen. While it stays in the white screen, I will unplug my power adapter and wait for my battery to drain out completely. Once the battery is completely drained out, I will plug in my power adapter and I'm definitely able to boot up my MBP without any problem the first time. I did the same and thus I'm able to post this question.
    2) Bootup into safe mode and restart. It works once
    3) I have also disabled dynamic switching of graphics card but that didn't work.
    Below is my error report. I don't quite understand it. I hope someone explain to me?

    Hi all, I had many problems with the GPU of my Early 2011 MacBook Pro and the MLB was replaced three times so far. The first time was about a year ago and I went to an authorised retailer and not to an Apple Store. They first incorrectly diagnosed the problem and told me that they had to replace the hard drive. After that, they still did not really find the problem but said that the MLB had to be replaced, which I did given that my computer was only two years old and running fabulously. About a month later the problem reappeared and the MLB was replaced again, this time by using the 3-months guarantee of the MLB. The first time I had to pay. A few weeks ago I again had problems (the computer was very hot and fans were running at maximum speed most of the time although I was running only Mail and Preview). I'm, I took it directly to the Apple Store and after about five minutes of looking at it they decided to replace in the MLB for free. There is no official replacement program but I think Apple has now recognised the issue and they don't charge you anything if you had the issue before (they call this a repeat repair). So good luck if you haven't solved your problem yet. If the problem reappears there should be no problem.
