One of the USB ports on my Macbook Pro isn't working. Any way I can fix this or will I have to take it into the store to get repaired?

I bought a Macbook pro this July. Everything has been normal except about a week ago I started noticing I had to plug things in a few times in order for them to connect. Today I realized that one of my USB ports has been the problem, not my devices. THey connect right away when plugged into the right USB port next to the SD slot, but not at all when plugged into the left slot by the firewire hookup. Is this a problem that has a quick fix or am I going to have to go to the mac store?

Reset the SMC and PRAM
SMC Reset:
Shut down the MacBook Pro.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer. 
PRAM:
Shut down the MacBook Pro.
Locate the following keys on the keyboard: Command, Option, P, and R.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

    QuestionWhy can I no longer use my exterior speakers connected to the USB port on my MacBook pro ?

    Have you checked the Sound Preferences under the System Preferences and set it to USB speaker for the sound output? Sometimes it can change on its own or after and update of an App or the OS?

    Try cleaning out the phone's port, of pocket fluff and such. Carefully. And check the mains adapter similarly, but less likely.

    B-rock, thanks for posting the above.  I actually have the same issue, running Windows XP and I don't have that backup location, \Application Data\Apple Computer\MobileSync\Backup\.  When I go to Documents and Settings\(username)\ there's a AppData folder followed by:\LocalLow\DataMngr\ .
    I have the latest update, 5.0.1 and I have the iPod Touch 3rd gen.
    I have tried removing itunes and all that is associated with it then reinstalling and keep getting the same message.  I've reset my ipod thinking that would help but still, no backup.
    In iTunes, Edit, Preference, Device there are no backups.
    What am I doing wrong, can you help? 
    Thank you!

  • USB Ports on my MacBook Pro are not working

    My MacBook Pro (Original) USB ports recently stopped working. They come up in system profiler as being there, but when I connect a device, such as a flash drive, no leds turn on, and no power is given to it. I have tried resetting the SMC and PRAM, but all to no avail. Does anyone have any suggestions? Thank you in advance for your help

    I had a nearly identical issue today with a new CTO MacBook Pro...specifically, the USB ports on this new unit were unresponsive to devices being plugged to their slots. We reset SMC to no avail, unplugged all other non-essential peripherals, and still no change.
    We were specifically trying to boot a previously functioning Seagate hard drive with a fully intact install of Snow Leopard. Eventually the MBP detected the drive and read the contents. We selected the externally connected drive for startup (which S/L found without issue) in System Prefs. At boot, no progress further than Apple logo (without animated gears indicating some type of load process).
    Moved to an identically equipped secondary Thunderbolt MBP which presented with exact same issue. To further verify this was an issue with the USB ports on a Thunderbolt model MBP, we attempted boot of the externally connected drive to an iMac and then a MacMini. Both of these units booted the drive without issue. The Thunderbolt MBPs can see the drive, read the contents, but can't boot them.
    Disk Utility verified and ran repair on the external drive and reported zero problems.
    Both MBPs are being returned to Apple. Too much to risk for only having two USB ports.

  • Updated OS X Mavericks and now USB ports and MS Office apps won't work. How do I fix this?

    I updated  my MacBook Pro (mid 2012) to OS X Mavericks 10.9.4 and now my USB ports and MS Office apps won't work.  What do I do to fix this?

    What system version were you running before you updated to 10.9.4? Another 10.9.x or something earlier?
    What version of Office? 2004, 2008, or 2011?
    Were you aware that Office 2004 does not run on recent versions of the system?
    When you say your USB ports do not work, on what are you determining that?
    Were you aware that Mavericks does not display external disk volumes by default?

  • HT1277 My ICloud was hacked. So the email box on my Macbook Pro isn't working at all. However, I can use it when I login to ICLOUD and my IPhone.  Why will it still not work on my laptop. Help please!

    Hi,
    My ICloud was hacked.  So I updated my password and now have my Iphone and the Icloud online email working.  Yet the email set up on my Macbook Pro still will not work and I ran through the troubleshooting.  It has ICloud IMAP.  Can someone please help me with this?
    Thank you.

    First, a caution: Do not retry passwords.  Trying random passwords or wrong passwords more than (usually) twice, and that'll usually trip evasion, and you'll get blocked even with the right passwords.  If you've retried random passwords, you'll have to let things "cool off" for a while, and try again later.
    Open up the details drawer in the Mail.app Connection Doctor troubleshooting, and re-run the connection tests.  Expurgate anything sensitive from the diagnostics, and post the iCloud-related errors here.
    Alternatively, remove the iCloud account from the accounts listed within Mail.app.  Re-add it.  See if that clears the issue.
    Alternatively and if the other options here fail, contact Apple iCloud support directly and request assistance.

  • The track pad on my Macbook pro isn't working well. The scrollbars are there but the only way it lets me scroll is with the arrows. It also doesn't let me highlight anything to delete it nor does it like me double click to open any documents. Help?

    It isn't letting me copy and paste so the question is the subject, I am sorry.

    Hi Miamel84,
    Welcome to the Support Communities!
    If your trackpad is unresponsive, a good troubleshooting step is to reset the PRAM and SMC on your system. The following articles will show you how to do that.  Also see the final article in this post that addresses general issues with jumpy or erratic trackpads.

  • FaceTime always fails on outgoing calls with my MacBook Pro. Is there some way I can fix it?

    Have I accidentally disabled a connectivity preference that subsequently disabled FaceTime? My connection is great, so that must be out of the question. I have tried calling it from another Mac and from an iPhone, but only then does it cooperate. I don't want to downgrade the FaceTime that came with my MacBook, so can someone help me out?

    The message that comes up when I click on "TomTom Home Install" is "You cannot open Home Install because Power PC applications are no longer supported." Does this mean that the TomTom, which is absolutely vital to my life - well, not literally but you know what I mean - can no longer be used with my MacBook Pro?
    What that means is that is can't be used with Lion 10.7.  PowerPC was the chip Apple used up until 2006 when they switched to Intel.  At that point, they created the Rosetta emulator to allow for PPC support for 5 years.  They finally dropped the support with the release of Lion.  It will only work with OS X 10.6 or earlier.  The other option is to purchase a new GPS, which can be had for $100 for a decent one.

  • My 2007 macbook is separating... is there any way i can fix this?

    computer is separating... how can i fix this?

    I'm not sure what that means, and am further confused by the tags and categories you have used.  Can you describe what's happening in more detail?
    Note that if it's a hardware issue, with two components separating from each other, you'll need to contact Apple for service.

  • Movie keeps randomly stopping as if its buffering even though its fully downloaded.  What the heck? Any way I can fix this?

    The download was fine but it keeps stopping.running slow. Its making watching the movie a pain.

    Wow, just posting and it seems that there is a solution that is working for me...
    What I've did is I turned off iTunes Match on my iPhone, then turned in on again. Now in my iTunes library on my mac I can get the duplicates to be matched or uploaded to iCloud with a right-click, add to iCloud. iTunes Match starts to check the songs and everything is done correctly. Pretty nice!

  • TS2634 My EarPods keep randomly turning down the volume when I'm listening to music?!?!? does anyone know how I can fix this, or will I have to invest in a new pair?

    this is so annoying! I will have my volume at the usual 6, and I'll listen to music and i won't touch anything but it turns the volume down until eventually there is no sound. this does not occur without the EarPods.

    If still in warranty return to Apple for evaluation

  • USB ports in my macbook pro stop working

    For a few months now the USB ports in my Macbook Pro stop working. The mouse is unable to move the pointer, therefore, I have to use the trackpad to select things. Then, when i try to shut it down it refuses to shut down, so I have to hold the on/off button to turn it off. When I turn on the laptop, the problem goes away. It's been happening more often for the last few weeks. Is there a problem with the software or is it the fact that I never used a base to raise the laptop, until recently, to let air in below so it doesnt heat up so much?
    Any help is appreciated.
