High pitched noise and 13' MacBook Pro (2010) not working at all

A few nights ago my computer starting making a high pitched noise and was immediately slower (barely working at all actually) I feared it was over heating so I shut it all down and let it rest for the night, the next day I went to start it up and the noise started again and I couldnt get passed the white screen that pops up when the computer is starting.
I'm fearing the worst and thinking it might be the hard drive or something. But I thought I would see if anyone else had any thoughts or possibly something I could try.

Applejack is just a command-line "front-end" for a number of different command-line tools you can use in single-user mode, and I'm not sure whether it's Lion-compatible.  You can always try booting into single-user mode and executing:
/sbin/fsck -fy
That's unlikely to solve your problems, though.  Since you can't boot from two different hard drives and your optical drive, that indicates there's a more serious hardware issue, or multiple hardware issues.

  • New Macbook Pro Keyboard not working at all

    My MacBook Pro keyboard is completely unresponsive. Any ideas?

    Hey Guys,
    I figured it out. By searching some other cursor/mousepad thread: I had to do a PRAM reset. Now it's working!

  • ICloud sync with MacBook Pro does not work

    I've installed iOS 5, updated Lion to 10.7.2, marked Calendar and Contacts sync in System settings for iCloud on my Mac. However iCal and Address Book sync between iCloud and Mac (MacBook Pro) does not work though there is no problem in syncing between iCloud and iPhone. Whether I create new event or contact, change existing one or delete existing one in iCloud this change is not reflected on my Mac and vise versa. I could not find a solution in this site or in forums.

    Yep, worked for me, too and now contacts and calendar seem to be syncing perfectly.  We'll see if it lasts.
    Thanks for your answer.

  • Macbook pro 2010 not showing hdd in disk utility but shows the same in usb

    Macbook pro 2010 not showing hard disk in disk uility but same hdd shows when connected to usb original drive, also installed new hard disk 500gb, same result, but connected old hard disk of 500gb shows in disk utility and also able to installed os on it, tried installing lion 10.7 on it with the original and new hdd but not shows in  disk utility pls help for this problem

    I'm kind of experiencing the same issue now.
    A few days ago, when starting up my Mini, I would get a warning that the system didn't recognize the drive with the option to ignore. I hit ignore and all seven drives would mount. Because I have seven drives attached, I had no idea what drive was giving the warning.
    Today that drive failed to load up at all. I ran disk utility and after several tries, it said repair was successful yet the drive will not mount.
    I'm currently running recovery software on it to see if I can copy everything from it to another drive. It is a fairly old drive, about 3 years old so it's time is short.
    I don't have any suggestions but mine does show in disk utility.

    I lost my iphone and my macbook pro does not show the icloud in system pref. how do i get icloud on my mac?

    iCloud is only available in Lion, 10.7. You will have to upgrade to Lion in order to get into iCloud. If you transfered a .mac or .me address to iCloud through mobile me, or you have another device iCloud enabled, then you can log into the iCloud.com website.

  • I interrupted a software update and my macbook pro will not boot. I have tried to reboot using the startup disc, I have tried to verify the disc, and repair the disc. It tells me I need to erase and reformat the hard drive then reinstall the operating sys

    I interrupted a software update and my macbook pro will not boot. I have tried to reboot using the startup disc, I have tried to verify the disc, and repair the disc. It tells me I need to erase and reformat the hard drive then reinstall the operating system. I do not have a back up of all my applications, my garageband music and other things. I also do not have time capsule set up on this machine, but I do have a 2 TB time capsule.
    Is there anyway to back up this corrupted drive so I can restore my applications later?

    There's an old saying.  If you don't have a backup disc, then there must be nothing important to backup.  That's just lesson #1.  Lesson #2 is to never interrupt a software update.  Not a good thing.
    OK, I'm sure you know this.  It just upsets me to read your story, knowing you have a lot of important stuff on your hard drive, and didn't use time machine.
    You're pretty much in a bad place.  My only hope for you is to boot to your Installation Disc, then using disk utility see if you can save the internal hard drive (by fixing what can be fixed).  You might be able to see your user folder and some of your apps.  I wouldn't even consider copying the library, because who knows what's been corrupted in there.
    Good luck.

    Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

    Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
    I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
    Thanks in advance!

  • I have a iMac desktop and a macbook pro laptop I work mainly on the desktop but when i go away for work I take my laptop. Is there any way to make it automatically back up to mirror my desktop? Like when I update a file it updates on there too etc?

    I have a iMac desktop and a macbook pro laptop I work mainly on the desktop but when i go away for work I take my laptop. Is there any way to make it automatically back up to mirror my desktop? Like when I update a file it updates on there too, if I install software it installs on there too etc?
    When I first got the laptop I syned it to load with all the same software etc but it hasn't continued to sync
    Thanks

    I use
    Chronosync (http://www.econtechnologies.com/pages/cs/chrono_overview.html)
    and
    Dropbox (https://www.dropbox.com/)
    Both work very well. The former I use for manual, one-way synchroniziation of (nearly) entire systems. The latter for automatic syncing of very active directories through local and shared online storage.

  • HT204384 I have a SanDisk Memory Stick PRO Duo and my MacBook Pro will not read it.

    I have a San Disk Memory Stick PRO Duo 4GB and my MacBook Pro will not read it. I have also connected the card into a card reader and connected it to the USB port and nothing happens. This is really frustrating. Why wont my computer read my card?

    Are both , the printer and the mac in the same network?

  • Any DVD I rent from the red box or at the library my 27"iMac and my MacBook Pro will not operate.

    Any DVD I rent from the red box or at the library my 27"iMac and my MacBook Pro will not operate.  The Mac's take the DVD's and it sounds like it's trying to run the DVD.  After about 10 seconds the Mac just spits it out.  I am using the newest version of the Beta Yosemite OS X 10.10.3 Version.  I'm a little more than a novice user, just to keep in mind... Can anyone help me fix this problem?

    Aside from running the beta (and not being allowed to discuss anything at all about it anywhere including these forums), I have found that some commercial DVDs (and actually also music CDs) are coded such that they will not play in any device that could ostensibly be used to copy the content due to DRM/copyright issues. The DVDs played just fine in both of my DVD players hooked up to my TVs and the music CDs worked in my stereo system.
    Have you tried to play those in a regular DVD player?

  • The sound on my macbook pro is not working

    The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
    There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
    HELP!!

    Hopefully one of these steps should solve the problem.
    1. System Preference > Sound > Output > Internal Speakers
        Highlight  Internal Speakers / Headphones
        Make sure Mute is not enabled.
    2. Remove the headphone.
        If you see red light in the headphone port, plug the headphone
        in and out of the port 5 or 6 times to flip the microswitch inside.
        Sound output may be stuck in the digital mode.
    3. Reset SMC.     http://support.apple.com/kb/HT3964
        Choose the method for:
        "Resetting SMC on portables with a battery you should not remove on your own".
    4. Applications > Utilities > Audio MIDI Setup
        Audio Devices window
        Side Bar
        Click the Built-in Output.
        Under Mute any of the boxes checked? If so, uncheck it.
