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.

    I would do another SMC reset. If nothing changes you should take the computer in to an Apple store for a free diagnostic. You should make an appointment.

  • I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

    I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
    if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
    because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
    can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
    Help.

    BB1B2,
    The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
    You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
    Sorry,

    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?

  • USB port at back of iMac stopped working except keyboard. Why?

    My USB ports on back of iMac stopped working, I can't seem to get any power from them. Only keyboard port works..
    My externals don't work neither and I got all my hard work on them. I think I've lost info?

    I have no idea what happened. However, I believe that you've got to take it back to the service provider and work with them. Call them and tell them what happened and see what kind of a response you get. You might want to try to get in touch with Apple Customer Service and see if they can help you out with the service provider.
    As for "compensation", that is probably a legal matter unless you have some kind of insurance that covers you for business losses. You might try to stress to the service provider that they should do whatever service is now needed to get the machine working again at no additional charge.

  • My macbook pro stopped working

    my macbook pro stopped working when i was out of town. i took it to an apple certified repairing store and they told me that as my waranty period was over 1 month back i have to pay 800-900$ to repair it. I would like to know if I buy an apple care now will it still cover the repairing cost?
    I also need to know what are the different repairings are supported by apple care.

    It would be hard to determine that at this point, but check out the articles below to get you going on isolating if it is hardware or software.

  • Why did my MacBook Pro stopped working

    Hey,
    Yesterday my MacBook Pro stopped working (got stuck on the opening screen with the spinning wheel)
    I fixed it..but my question is what made it do this?
    Thanks,

    Oh - your profile shows 10.8 - which is Mountain Lion.
    There's no telling what could cause a one-time event like that - could be any number of things - but if it happens again, call back.

  • 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.

  • 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.

  • Backlight on macbook pro stopped working

    Hi,
    I am new to apple, I purchased a second hand macbook pro 15" recently (1.83Ghz 2GB Ram, 220GB HDD). I'm pretty sure it has the most recent vesion of Leopard (cannot confirm). The only real issue with it was the battery life (about 15mins)
    anyway, I recplaced the battery yesterday... when I tried to turn the machine on the screen lights up "as normal" I get the apple startup chime.... but then the screen just goes dark.. You can kind of see the desktop and windows etc if you tilt the screen toward the light but there is zero backlighting. I tried the F1 & F2 keys, nothing :-/
    I plugged my PC monitor into the DVI port and it works fine. So, I managed (with great difficulty) to get the system prefs open and onto the secondary monitor. When I click "displays" it just hangs with the spinning rainbow cursor and never actually opens the display preferences.
    To make matters worse I thought I'd try starting the computer from the OSX leopard DVD... which worked, but still no backlight whatsoever. So it's in DVD boot mode now... cannot seam to eject the disc either.
    Yes, I tried with the old battery... no love
    I'm happy to take it in to get fixed if I have to... But I'm wondering if anyone knows what is going on with it, or if there is something I've done to it..
    Cheers
    Dan

    Welcome to Apple Discussions and the world of Mac. Hopefully subsequent experiences will be better than your initial one.
    It sounds like the second hand MBP has an inverter problem. The inverter is a high voltage circuit that powers the fluorescent lamp that backlights the LCD display. That kind of failure is a hardware failure so a repair will be required.
    Since you have an external monitor, do you also have a USB mouse and keyboard? If you do, you can use the MBP with the lid closed with all those external peripherals attached and it should make controlling the Mac easier without the internal display working. Just attach the external monitor, mouse and keyboard and the MBP's power adapter and hit the start button on the MBP and then immediately close the lid on the MBP. That should cause the internal screen to stay off and only the external screen to be used. Alternately, if the MBP is already running, if you close the lid, it should go to sleep. Then, keep the lid down, and hit the space bar on the external keyboard and that should wake the MBP up with only the external screen active. The power adapter needs to remain attached to the MBP for the above the work. Good luck.

  • Provide USB port power during Macbook Pro Sleep mode

    My old Macbook used to go to sleep, with lid closed, and charge my phone via USB cable.
    With my i7 2010 15" Macbook pro however, I cannot see how to configure this same feature. Basically when the lid closes, the unit goes to sleep, including the USB ports.
    In order to charge my phone, I am forced to leave the computer on.
    This seems like a giant step backward for a traveler like myself, one of the main reasons I made the investment in the new Macbook Pro was for the great new battery life.

    I have the same problem. This was working, but it seems that after the last security update all USB ports are turned off completely, so my iPhone and iPad (both of which I leave connected to the USB ports) do not get charged. This is a big deal with my iPhone.
    Is there a configuration parameter on my MBP I should check?
    Thanks!
