July 2011 15" macbook pro now freezing temporairly every 10-15 seconds

I'm having an issue with my summer 2011 macbook pro 15".
typing, web browsing etc.. every 10-15 seconds the whole computer freezes for about 5 seconds then repeats.  it's really annoying to use this way.  it affects all functions.

Hi...
How much free space on the startup disk?
Right or control click the MacintoshHD icon on your Desktop. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
If there's enough free storage space on the disk, try Starting up in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient. Once you see the Desktop, click the Apple menu icon top left in the screen. From the drop down menu click Restart.
If the drive still freezes after booting in Safe Mode, since you are running v10.7.4 Lion, use Lion Recovery  to repair the startup disk or reinstall the Mac OS X.

  • My 13" macbook pro 2012 freezes totally every now and then

    I bought my mac aproximately 1 year ago, and now it has started to act wierd. After using it in like 5 minutes, parts of the screen suddenly flashes green and proceed to a status of freezing. i can't move the mouse or do any kind of type-commands. the only thing that helps is to hold down the powerbutton until it turns off. when i have started it again it does the same thing over again. Do anyone know of this problem, and maybe have a solution, or just an idea of how to solve this problem? please help me :/
    - right after buying it i changed the RAM to 8 gigabyte, but haven't had any trouble with it.
    and also sorry for my - probably - not so good english

    I ran the short and long hardware tests this afternoon and nothing came up. So there's no detectable hardware defect.
    At the moment I don't suspect the drive. Today I've been running iostat in a terminal the whole day and I see no change in disk activity (or system load or anything else for that matter) when the freeze occurs. iostat keeps reporting the same numbers the whole time. Maybe it's something on the mainboard or a driver/OS X issue. Or an interrupt issue since everything that I did during the freeze gets done instantly after the systems starts responding again.
    Monday I'm going to call Apple to report all of this. Since Apple Support only heard of this issue from you I expect I'm going to get a replacement MacBook Pro. But I suspect that there's a good chance I'll be getting another model with same issue.
    A friend of mine has ordered the same configuration as I have at the same time. She hasn't experienced any problems so far. She's going to pay close attention to her MacBook tomorrow when she boots it in the morning. And in a couple of days we're going to test them side by side. I'll keep you posted.

  • My 2011 15" Macbook Pro occasionally freezes and beeps loudly in groups of three. What is causing this?

    This problem typically occured when I was doing something particularly strenuous, but I just recently had it happen while browsing the internet. The computer will suddenly freeze and start beeping loudly in groups of three with an LED on the front flashing in sync with the sound. I am running Snow leopar if that has any bearing on this problem. What exactly is causing this?

    I did a few things to correct the problem First opened up my unit and cleaned it out really good and cleaned all the dirt and dust out Second I removed all the ram and cleaned all the ram connector and  ram connection points on the board Reinstall OS like a new system scratch and restored my applications Zapped SMC and pram And I'm running smoothly ever sice
    At one single problem at all One more thing I got a laptop cooler and I run full-time now when using my system. I spoke to a techie and told me all MacBook Pros run very hot. It seems to run a lot better with the cooling fans going.
    not a single problem ever since. Make sure you have the latest ML to, Some fixes to memory controller were added.

  • My Macbook Pro keeps freezing up every 5 minutes

    I got my MacBook Pro new in late July and I have never had any sort of trouble with it. Since yesterday, my MacBook has been freezing up. At first it happened every once in awhile and then I started to notice it happened every ten minutes, like clockwork. It is not as frequent as every 5 minutes and I do not know the solution. It occurs no matter what program I am running. I was using chrome and I was on Youtube and the page would freeze up but the audio would continue. Now, when I run iTunes, everything freezes and stops including audio. The freezes last for about 30 seconds to one minute. I have tried a disk repair and that did not solve the problem. Now what?

    Hey tmcguin,
    Thanks for the question. I understand you are experiencing performance issues with your MacBook Pro. The following resources may help to resolve your issue:
    First, you may want to reset the SMC:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    http://support.apple.com/kb/HT3964
    If the above does not resolve your issue, you may want to perform a Safe Boot:

    Thanks,

  • My Macbook Pro keeps freezing/crashing after a few seconds of use, but works fine in safe mode.

    I've researched this extensively, but I haven't been able to solve my problem yet.
    It started completely out of the blue with a kernel panic, where my screen seemed to malfunction and I got the kernel panic message (but I could hardly read it because of distorted graphics). I forced my laptop to shut down, but every time I rebooted and used it again it would completely freeze after a while (the amount of time varied, it has lasted from a few seconds to a couple of hours). What happens essentially is that the cursor and entire OS freezes, and I'm unable to click on anything or use the keyboard. The fans start working full speed and the only thing I can do is force the laptop to shut down.
    At first I thought it was a Chrome problem because it only happened after I opened the browser. After uninstalling it, the laptop seemed to work fine for a couple of hours, but then it froze again while I was using Safari. Ever since it has been functioning normally for smaller and smaller time periods before freezing again. I've tried reinstalling Snow Leopard OS from the original disc and then downloading all software updates, but the problem continues. I've also tried doing a hardware test by pressing D as the computer starts up, but for some reason it doesn't work.
    The laptop, including Chrome and Safari, works fine in safe mode.
    I'm sorry I don't know what specific information to give you about my laptop/OS, but please ask anything you need to know. I'd greatly appreciate any help — I'm panicking because I fly to England tomorrow morning to start university and I really don't want to go without a laptop for 2 weeks while it's getting fixed!

    Thanks for your reply! Here are the Etrecheck results.

  • Why is my Macbook Pro Retina freezing almost every day since I have installed Mavericks?

    I bought my Macbook Pro Retina in March and only use it lightly for school. I don't do anything crazy on it, and I have used barely any space on it. I have never had any problems in terms of freezing, but ever since I installed Mavericks, it's been freezing almost every day. Is there any way to stop this? It's very frustrating because I will be in the middle of something and it will just stop working. The only way to stop the freezing is to hold down the power button until it shuts down. By the time I restart it, I've lost my work. I wouldn't mind reverting back to Mountain Lion, if it's possible, because I never had any problems with it. But if I can fix it without reverting to Mountain Lion, that would be preferable. Any help would be greatly appreciated, thanks!

    Lots of people have this problem too but no one has a reply, any suggestions??

  • My mid 2010 macbook pro keeps freezing/crashing every time I try and play a game. Any help?

    Every time I try and play either WoW or The Sims, my mac goes to black screen, or black screen and repeating last second of noise it was playing. I haven't upgraded to Lion and am still using Snow Leopard(??). I am by no means the most tech savvy girl in the world, but would appreciate any help, as this is driving me insane!! Thanks!!!

    I don't know if it would help, but this is all the whoo haa from the last panic report thing. (about 5ish minutes ago)
    I don't really know what any of it means, but if someone could help me decipher and tell me if there's anything I can do, I would be super grateful. (before I go into apple, that is)

  • I have bought my MacBook since July 2011. It has now become frustratingly slow. What shall i do?

    I have bought my MacBook Pro since July 2011. It has now become frustratingly slow. I tried using the HELP key but did not seem to find any helpful information.  What shall i do?

    Things You Can Do To Resolve Slow Downs
    If your computer seems to be running slower here are some things you can do:
    Start with visits to:     OS X Maintenance - MacAttorney;
                                      The X Lab: The X-FAQs;
                                      The Safe Mac » Mac Performance Guide;
                                      The Safe Mac » The myth of the dirty Mac;
                                      Mac maintenance Quick Assist.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X 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.
    Repair the Hard Drive - Lion/Mountain Lion/Mavericks
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
    When the recovery menu appears select Disk Utility. 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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
    Suggestions for OS X Maintenance
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
      Mac OS X Snow Leopard and malware detection
      OS X Lion- Protect your Mac from malware
      OS X Mountain Lion- Protect your Mac from malware
      About file quarantine in OS X
    If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
    Troubleshooting Applications
    I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
    If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
    Basic Backup
    For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
    1. A Time Machine preferences panel as part of System Preferences;
    2. A Time Machine application located in the Applications folder. It is
        used to manage backups and to restore backups. Time Machine
        requires a backup drive that is at least twice the capacity of the
        drive being backed up.
    Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Get Backup
      3. Deja Vu
      4. SuperDuper!
      5. Synk Pro
      6. Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
    Referenced software can be found at MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Pre-Mavericks
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Mavericks and later
    Open Activity Monitor in the Utilities folder.  Select All Processes from the View menu.  Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

  • 2011 17" MacBook Pro freezes for over 5 mins on user password

    Hey everyone,
    I installed Yosemite on my 2011 17" MacBook Pro. Since then, after a period of my computer being on or after sleep, it appears that the process that handles login using my user password hangs for a bit and then proceeds to work.
    On the login screen, after I enter my password, the focus is drawn off of the password field, and then the computer just sits for what seems to be about 5-7 minutes. This also happens when OS X asks me to enter my password to install / uninstall something; the login window just sits there and does nothing.
    It doesn't happen right after a restart, and it seems like it happens more often after the computer goes to sleep and wakes back up, or has just been running for a while.
    A couple other possibly related problems is that my system will sometimes just start to slow down and every app will slowly become unresponsive, sometimes to the point where I have to use the power button to do a hard reset. Also I've noticed that my system won't remember that I set my screensaver to "never" but will reset itself to "15 minutes" (which is annoying, because after I come back from the screensaver, my system takes a long time to log back in).
    I can't do a system reinstall right now, and I've tried to do PRAM resets and disk repairs. Maybe I'm googling the wrong words, but I've searched and I can't find threads with my exact issue.
    Can anyone help? Thanks!

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
         computer and after the chime press and hold down the OPTION key until the boot manager
         screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. 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 main menu. Select Restart from the Apple menu.
    4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    5. Reinstall Yosemite from Scratch:
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    How to Clean Install OS X Yosemite
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • My MacBook Pro is freezing and then restarts.  Kernal Log showing I/O errors

    My MacBook Pro is freezing up and then restarts.  It started happening about 2 weeks ago.  After several attempts to resolve it, I did a clean install of snow leopard.  And then did a SW Update.  I have no thrid party devices, ram, or HD.  My machine is 2 GHz Intel Core Duo.  2GB 667 MHz DDR2 SDRAM.
    My Kernel log is showing a bunch of I/O errors.   I think I have a sick baby.  Any thoughts

    William, Thank you.  I did do the reformat with the DVD SL Disk Utility with the write zeros once option. 
    I think the way to go is buy a new HD.  They are cheap enough.  In researching this, I found some discussions that there are some possible issues with using the newer SATA 3.0 GBs drive on my old intel core due macbook pro.
    Here are 2 threads - https://discussions.apple.com/thread/2673222?threadID=2673222&tstart=180 and http://www.mac-forums.com/forums/apple-notebooks/206962-will-hard-drive-fit-my-m acbook.html
    Do you have an opinion on that?
    I found this one http://www.bestbuy.com/site/Western+Digital+-+Scorpio+Blue+250GB+Internal+Serial +ATA+Hard+Drive+for+Laptops/9024147.p?id=1218012522486&skuId=9024147&st=WDBABB25 00ANC-NRSN&cp=1&lp=1
    which looks like it is compatible.
    Am I better off buying a genuine apple replacement or an OEM?
    Thanks

  • 10.9.4 update- MacBook Pro now too slow to use

    I installed the 10.9.4 update on July 17. Early 2011 13" MacBook Pro. It has since become too slow to be functional. 'Spinning wheel' constantly, and delays after keystrokes. I had no problems at all before this update. I have read that repairing disk permissions sometimes helps and have tried that. I sometimes have brief periods of normal performance, then it slows down again.
    The problem is not specific to an application. It is slow regardless of what I am doing, even when first staring up and logging in.

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
    Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
    You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
    In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
    You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
    Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
    4. Here's a summary of what you need to do, if you choose to proceed:
    ☞ Copy a line of text in this window to the Clipboard.
    ☞ Paste into the window of another application.
    ☞ Wait for the test to run. It usually takes a few minutes.
    ☞ Paste the results, which will have been copied automatically, back into a reply on this page.
    The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
    5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    8. Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
    9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
    exec bash
    and press return. Then paste the script again.
    10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
    14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

  • Apple original battery for the Early 2011 17" MacBook Pro

    The original battery is failing on an Early 2011 17" MacBook Pro (MacBookPro8,3), 2.3GHz - it has lasted 43 months according to coconutBattery. Often refuses to charge at all, holds about 6750mAh as compared to the original 8450mAh it could hold upon delivery. The battery has gone through 848 "loadcycles", not so far off from Apple's suggested 1,000 cycles, which I assume they meant should have taken place during the AppleCare period which ended 3 years after purchase = April 2011 - April 2014. The battery began having charging problems in June-July 2014, after 3 years and 3 months.
    Have looked for a replacement battery and found many. What they have in common is they are (with one exception) not Apple, and specs differ from the original (the original specs taken from the battery the MBP was delivered with as new are 31CP90/44/89-2  Li-ion Polymer 10.95V 95.0Wh Model No. A1383).
    An Apple certified service center in Stockholm Sweden offers an original Apple A1383 battery with identical specs, but: they only offer a 3-month guarantee! Even worse, they claim that they cannot discern the manufacturing date (or will not provide it).
    I contacted OWC (macsales), have always been happy with their products and service and knowledge. They hold that they cannot offer this battery at all but that it should be available in the Apple Store, ie online. But we cannot find it there, one of the few models missing.
    Probably a lot of people with an Early 2011 17" MacBook Pro 2.3GHz will be having this problem right around now. Has anyone found a great solution?

    Have you tried ifixit or PowerBookMedic?

  • Complicated problem: Laggy Macbook Pro, now not booting

    I am facing a very complicated issue with my unibody Early 2011 15" Macbook Pro (2.2 ghz core i7, 4gb 1333mhz ram, amd radeon 6750m, if you need hardware details).
    I guess the issue started after my computer started to get laggy for no reason at all: it was never the GUI that lagged, but whenever I would perform some data-dependent tasks such as playing a video, or trying to open a big file. This lagging did coincide with some of my friends playing around with magnets around my computer (which may have possibly corrupted hard disk data).
    After it got laggy, another major problem hit my MacBook, where I plugged in an old, broken USB into one of the ports by accident, and the computer suddenly shut it self off. The computer then seemed to have no power at all, with no response to pressing power button, or the battery indicator button. I feared the worst: that my logic board had been fried, so I immediately took my computer to the Apple Reseller. The technicians there said it was no problem at all, just that my motherboard had shut itself of in order to protect itself from a USB power shortage, and he unplugged and replugged this one small component on the logic board, which I am guessing is the Power Management Unit, and my computer miraculeously started booting.
    So then, I get back home, and the laggy problem is still there. I just had to cope with the problem for a few days, until I go back to the Apple Reseller, but then suddenly, after a restart, the computer started not even booting. The grey apple icon would blink, and turn into a circle with a cross icon. Checked online, and this is apparently related to corrupted system files. This is where I began to suspect that the USB shut-off from few days ago, did more damage than the technicians thought: maybe related to the hard disk, or RAM.
    But then again, it could have just been a coincidental corrupt hard disk from my actions, so I wiped/repartitioned my hard disk, and restored the OS and my files from a TIme Machine Backup. Again, the problem was still there, so I thought it might be to do with my backed up system files, so I did a fresh install of Lion.
    The fresh install of Lion seemed to eliminate all lagging problems, but after I started copying my files and installing applications from Time Machine, the lagging problem gradually returned. So another question arose, was it a faulty hard disk, or a corrupt file or application that was making it laggy? To check if it was my hard disk, I did a zero-over erase of the entire disk with Disk Utility, and sure enough, the writing process failed in the middle.
    After thinking I zeroed in on the problem, I replaced the hard disk in my Macbook Pro with another 750gb Toshiba SATA drive, and did a clean install of Lion. Once again, the laggy problem was gone, but just like the old hard disk, the laggy problem returned after I started copying files over and installing applications. Switching applications would take forever, and accessing folders on my hard disk would also be laggy. Playing videos was impossible, but the GUI (dock, spaces, etc) were all very responsive.
    Now, I thought the problem is either with faulty RAM, or my hard disk reader is broken (since two hard disks, although the original one was faulty, both failed). I read online that the Apple Hardware Test (AHT) can help identify and pinpoint hardware problems, so I inserted the 2nd disk that came with my computer (Applications Install), and pressed D, but then nothing came up. After countless attempts, I maybe thought it was the wrong disk, so I inserted the 1st disk (OS Installer), and held D while booting, but still, AHT would not load.
    After countless attempts at loading AHT, all of which led to me forcing shut down/holding power button after seeing the Apple logo, brings the problem to where I am at now: my Macbook does not boot into the login screen. After the Apple logo, and the spinner wheel have appeared, the screen turns white and the display becomes an infinite loop of switching from a gray color, to a white color.
    This problem is frustrating me very much, because there are so many possible causes, and the problem persists even after reinstalling the OS, and even replacing the ard drive. The logic board shutoff could be the cause, but then again, the lagging problem started way before it happened. Somebody please tell me what is the problem, and what I should do? Thanks in advance.

    Didn't know my magnets were strong enough to corrupt hard disks.
    Yes, it's a method used to destroy data on a hard drive as it's recorded using magnetic fields, either "on" or "off" to represent the 1's and 0's that make up the basic building blocks of your data.
    But, the magnet does not explain why the hard disk reported an error when being erased with zero-over option.
    When the driver software has a problem reading the data on the drive, it assumes it's a bad sector, then maps it off and uses a spare. You likely ran out of spares.
    I just tried zero-over erasing the second, good hard disk that replaced the original, but again, it fails. Is this a common problem with the zero erase option?
    No.
    or is it something to do with my hard disks, or some sort of damaged hardware in my computer?
    Well this is drive #2 and it's new, and you get the same problem.
    It's either something your doing, (like moving the hard drive/ computer while it's operating thus the heads are striking the platters) or it's a hardware defect, or perhaps the magnets did other damage we can't see, perhaps it's magnatized the computer and that's affecting the hard drive or electronics.
    May be a loose or defective cable.
    It's time for a hardware evaluation at this point.

  • Early 2011 2GHz Macbook pro distorted blue screen then wont boot, 3 times in last 2 weeks

    I have an early 2011, 2GHz macbook pro (15' model with ati radeon graphics). It was running fine for the last two years. Over the last couple of weeks, following things happen:
    1. I was running on bootcamp windows, browsing and some flash content was open, suddenly distorted blue stripes appear and it froze. Force shut down using power button, turn on again and it wont boot on windows or mac, or recovery partition or from the dvd. Tried for about 4 hours, after nvram, pram reset, it was able to safe boot, then run disk utility to verify and repair the disk, it said that there were problems with hard drive and fixed,then booted normally.
    2. I thought that the problem might be because I was on windows, so took a back up of the windows drive, erased it and installed windows 8 using bootcamp. It ran well for an week. After that, once I connected it with the tv using HDMI to watch a video, after I disconnected it, the screen was garbled over the windows start screen, but I was able to command restart normally. After restart, it wont boot to windows or mac.
    3. After several hours of trying, i was able to boot using the dvd this time, it said it 'can not install mac on the hard drive', erased the hard drive and it was able to install the os (snow leopard). After completing install, logged in to app store to download previously purchased mountain lion. Then ran it to upgrade the os, after the upgrade was completed, at the point when it prompts for apple id and password to set up icloud, it again froze with distorted blue screen. Shut down forcefully. Then turn on again and it wont boot. After the white screen and the sound, it shows the apple logo and spinning wheel for a while, then a bright white screen and nothing happens.
    Can anybody help reading the symptoms?

    I have the Early 2011 2GHz Macbook Pro and I have the same problem too.
    I switched out the logicboard a month ago and today the graphics just went distorted.
    Any solutions? Now I'm thinking it is the Graphics Card.

  • You can't upgrade to a 7200rpm hard drive in the Early 2011 13" MacBook Pro. It is not supported. Period.

    I tried unsuccesfully to upgrade the hard drive in my Early 2011 13" MacBook Pro to a 750GB 7200RPM hard drive. After several attempts with different hard drives I realized that the kernel panic that showed up was due to the lack of compatibility with the drives to the MacBook Pro. I had a Mid 2009 13" MacBook Pro that I did not have any issues with whatsoever. I sold that MacBook Pro and was able to upgrade to the brand new base model without any out of pocket cost. Upon purchase of the new 13" MBP I maxed out the RAM to the full 8GB. After 2 months of freezing, lockups, spinning rainbow wheels and having to force shutdown I tried one last ditch effort to see if a faster drive would help. After speaking with the Apple telephone reps and the Apple Store Genius Bar we discovered that Apple doesn't even offer the option of a 7200RPM drive on their website - a fact that I found quite disturbing. The concensus is that it is a power management issue that causes the incompatibility and the reason the drives are not offered on the 13" models. The problems I had were the end of the line for me. I just switched out that train wreck for the Early 2011 15" MacBook Pro base model. I got home and immediately installed the 750 GB 7200RPM Western Digital Scorpio Black hard drive and it was recognized within seconds. I'm back in business with gleeful abandon.

    Sadly... they don't have all the answers. As someone who use to serve in the capacity (Mac Genius) it can definitely be a challenging position. You're "the voice" of Apple's service policy & procedures. Sounds like the person you spoke with got it wrong this time. It's definitely worth a follow up, because like I said, I've got a machine in my household that's living proof of compatibility between a 7200 RPM drive and 13" MBP (Early 2011).
    Apple is very good about support documentation when there's incompatibility or unsupported configurations, the fact that there isn't one for 7200 RPM drives would tell me that the people/person you spoke with was misinformed.
    I know I always appreciated when a customer made it known to me that I was wrong on something and supplied the right answer. I sure as heck don't have all the answers and if I can lead from my mistakes, well, I won't make them anymore.
