17" MBP Left side usb ports and audio stopped working

Hello All,
I have a situation here with my MBP. A couple months ago it stopped detecting my airport card (not installed), I replaced it with another one which still showed as not having a card installed. So, I have just been using a usb wifi adapter which has been working fine, but recently the 2 usb ports on the left side have stopped working as well as I lost any sound. I've tried with or without headphones, still no sound it just shows a greyed out speaker and a circle with a line through it when I try to adjust volume. My initial thought was that the left I/O board was bad, but the dc-in board continues to work which, I believe, is part of the left I/O board. Any help or ideas would be greatly appreciated!

Is the machine at least 4 years old?  If it is symptoms you are getting is a sign the PRAM battery is about to go.  Get it replaced.  If not, try zapping the PRAM.

  • All USB ports seem to stop working "randomly" but some remain functioning until unplugged and plugged back in. [WINDOWS 8.1]

    The devices that die right away are the network adapter and any USB memory stick plugged in, they still have their lights and all running but aren't recognized in "This PC" and the network adapter isn't found in "Control Panel\Network and
    Internet\Network Connections".
    My keyboard, wireless mouse that runs through the keyboard's USB ports and the external HDD remains functional UNTIL I pull the plug on them, after that plugging them back in does nothing.
    I put randomly in quotations because it seems to fail more often when I download something at speeds over 3Mb/s, for an example downloading Hearthstone through the Battle.Net client will more often than not make the issue happen after a little bit. BUT it still
    happens randomly during NO network load what-so-ever.
    Parts: 
    CPU| FX-8350
    GPU| Radeon 5850
    Motherboard | Crosshair IV Formula
    RAM | 2x DDR3
    PSU | 700W Gold 
    SSD| Evo 850

    I HAVE:

    * Installed all Windows 7 drivers I could find except the BIOS ones due to lack of Windows 8.1 drivers from http://www.asus.com/Motherboards/CROSSHAIR_IV_FORMULA/HelpDesk_Download/
    * Turned off "Allow this computer to turn off this device to save power" in Device Manager for ALL devices in the USB tab that had the option, and the Network tab.
    * Set the Power Options to high performance and disabled "USB Selective Suspended Setting"
    I simply don't know what to do anymore and it's breaking me down, I need this fixed before the weekend or the LAN I'm planning to go to will be a disaster and I'll probably go insane trying to solve this myself. 
    Just tell me whatever more information you could need and I'll supply it, I'm desperate to get this solved.
    **I never had any of these issues on my old PC that had different parts but the same network adapter and external HDD so they are not to blame for this, same for keyboard and mouse.**

    Hey, I hope this helps you out a bit... I have had the same issue on my Asus K55A notebook with Win8.1 Pro x64 from the beginning! Thru my extensive research I found something interesting and the possible cause to all this! What I found was that by design
    the xHCI Host Controller has virtual HS 2.0 Ports linked to the 3.0 Ports... Enabling compatibility with 2.0 devices ok... What happens is that the xHCI stack is unstable just like you say... The ONLY WAY I was able to fix the problem was by unlocking the
    UEFI/BIOS to allow me full access to USB Configurations... I had to disable 2 of the HS ports under the xHCI Controller since I have only 2x 3.0 ports... This allowed 3.0 devices to be enumerated correctly under the xHCI stack and 2.0 devices now were enumerated
    under the EHCI 2.0 stack... That's what worked in my case... I'm still digging around for more info about this issue because I find it so odd that no one discovered this when designing xHCI stacks and drivers at MS for Win8/8.1 x64... I hope I shed some light
    on this issue... Good luck and keep us posted!
    Hi, Sebastian. I have the same problem but i'm getting crazy trying to solve it. Can you help me to unlock the UEFI to access full USB config? and give me some suggestions on how to solve the problem?
    My mail is roquen(at)gamail(dot)com
    Thanks in advance!

  • My speaker on the left side of my computer has stopped working.

    The speakers on the right side of my computer has stopped working properly. I have checked the balance and tried to trouble shoot the problem but nothing has worked. I now think that it is a hardware problem. What is my next step.

    I Assume that you are talking about the "All Inboxes" mailbox where you can tap to see every email in all of your email accounts. If it disappeared, tap the Edit button at the top of the window, then look for it in the next window. Select it by putting a check mark next to it, then tap Done.

  • Mac Pro USB ports and bluetooth not working

    I have a Mac Pro (early 2008) Quad-Core Intel Xeon, 2.8 GHz, 4GB ram, Airport card, Magic Mouse. Suddenly the keyboard and wired/bluetooth Mouse are unavailable, so it is not possible to control the computer. The only way I can use it is by using Screen Sharing from my MacBook Pro - which is obviously pretty useless except for diagnostics! All the USB ports (front and back, as well as those on the Cinema Display - when connected) are dead. System profiler shows no problem with them, but also shows nothing connected. Bluetooth in menu bar shows as "Bluetooth: not available", and in system profiler shows as "No information found".
    I've tried all the usual remedies. Powering off overnight with power cord disconnected, all peripherals disconnected, then booting up again. Holding in the power button for ten seconds when the power cord is disconnected. Obviously I can't reset the pRAM (because the keyboard is not recognised, even before the OS loads). The first couple of times I tried this process, it did bring back the USB ports, even the bluetooth became temporarily available, but soon disappeared again. USB ports died next time I rebooted.
    However, in the last couple of days, the process produces no results. No matter how long I leave it disconnected, USB ports are not working and bluetooth is just not there...
    I've checked for other threads on this topic, but most other people seem to have issues with either front or back USB ports, or even just one or more individual ports. My problems have only been with all ports or none.
    Does anyone have any suggestions to get my MacPro up and running again properly?

    Just waking this thread up again in case anyone has had any other ideas.
    Since last posting, usb became functional again, (came back on a couple of hours after a restart) and as long as I kept the machine alive, usb would stay alive. Bluetooth came back on briefly, but for most of the time was unavailable. System profiler shows no problems and Console does not report any usb related errors as far as I can see.
    After a recent restart, usb disappeared again, and despite numerous restarts and being left on for a couple of days (and subsequently left off for several days) it has not come back. When usb is not working, examining the system profiler (through screen sharing from my macbook) usb shows no errors, but also shows no connected devices. I can charge my ipod nano with any of the usb ports (front or back), so power does not seem to be the issue.
    I can't reset pRAM (because the keyboard is not available at boot), but have reset SMC numerous times. Have tried other keyboards, and mice. No joy.
    I seem to have run out of ideas. Any suggestions?

  • T400 - crappy USB ports and refusing to work with HP keyboards

    Hello forum,
    I work in a large multinational company and all of our laptops are now IBM Thinkpads from T60's, T61's, and now of course they're Lenovo T400 and T410 laptops.
    Also we still have some of the Thinkcentre towers.
    There seems to be other people with the same problem where the weak plastic / incorrectly sized ports are causing problems.
    Well i've just had my 4th Lenovo laptop cause problems and so far they've all be T400's or T410's with the exception of one Thinkcentre.
    Each time there is a problem its because the crappy plastic they used to make the usb port pin protector has snapped off except in the case of the Thinkcentre PC.
    The problem is that the vast majority of our keyboards are the basic HP keyboard and all of a sudden the keyboard stops working with the laptop.
    The keyboard could be working fine for weeks months or days and then all three lights will light up at the same time on the keyboard (num lock, caps lock and scroll lock) and the keyboard will no longer function.
    The only work around for the problem is to swap out the keyboard with an older Fujitsu Siemens Keyboard, or if i can find one an actual Lenovo keyboard.
    Do some lenovo systems have an allergy to HP keyboards?
    Or could someone tell me if theres a different cause for this problem.

    which HP keyboards are you talking about? there are quite a few different model of HP keyboard used by businesses.
    Also, is this problem caused by one keyboard or multiple HP keyboards?
    Keyboards should be designed with interoperability, but sometimes a usb could be badly designed where it pinches the usb ports.

  • Firewire, USB ports, and Spotlight not working

    When I got home and booted up my iMac G5, I noticed that my 4G iPod was not recognized by FInder and iTunes, like it did before. When I tried resetting my iPod, I checked and it was working fine. Then I tried changing the port to which my Firewire connection was. Still nothing. I tried shutting down, but midway, it hanged. I had to do a hard reboot (pressing the power button for a few seconds) When it started up again, I noticed that my External HD, connected by USB was not recognised. The weired thing is, it recognised the other external HD( I have two connected by USB). I wanted to search in the HELP section for troubleshooting tips but when I typed in Spotlight, it wasn't working. I tried it in both the Desktop and Finder. Not working. Even Software Update hangs on me. WHAT DO I DO? HELP!
    Another thing, My iPod is still working and is still being charged by Firewire, even though it doesn't appear on my desktop, iTunes and Finder.

    Perform all the "usual diagnostic routines" to see if it cures the problem:
    1.Repair Disk Permission then restart the Mac and see how...
    2.If this doesn't work, boot from the OS disc and run Disk Utility; If Hardware Test is on the same disc, usually the DVD version, run it too to determine everything is OK
    Good luck and cheers; Oh, it's best you run all these with all extra accessories, pheriperals etc plug out, i.e. meaning only your keyboard, mouse is plug in, do note that running the Hardware Test may require a wired keyboard and mouse.
    Cheers

  • W510 Docked in 433820U Port Replicator USB Ports Occassiona​lly Stop Working

    Has anyone had the problem where the USB ports on the 433820U Port Replicator stop working? I've had it happen on several occassion where the USB ports on the port replicator stop working when I do something seemingly unrelated (e.g. unplugging a CAT5 network cable, dropping something on the desk near the docked laptop). Once this happens, I have to unplug the USB devices from the port replicator and plug them into the laptop's USB ports in order to continue using the keyboard or mouse, or turn the laptop off and then back on. I'm trying to figure out if this is a defect in the port replicator or some outdated driver. Anyone else have a similar problem?

     This system supports USB3 ports but they are only USB2 on the port replicator. What's up with that?
    Hi William:
    I kinda, sorta think that the reason that the USB connectors on the Dock are only USB2 has to do with the speed of the connection between the big dock connector on the bottom of the notebook and the USB ports on the back of the Dock.
    I notice a similar problem when I had a W500 and a earlier model Dock.  That earlier model dock had an UltraBay in it.  If I put a hard drive (installed in a caddy) in the Dock, it ran very slowly - as if it was connected by USB - but if I put the same hard drive in the same caddy into the UltraBay on the side of the W500, it ran very, very fast.  So, all I could attribute this to was that the data just could not flow through the dock connector on the bottom of the notebook as fast as it could flow through the UltraBay connector on the inside of the notebook.
    Perhaps the same concept applies to the USB connectors on the Dock... maybe the USB3 connectors on the notebook itself have a faster data connection into the computer than the USB connectors on the dock, which need to pass through that big dock connector on their way to the computer.

  • Modem problems on Right Side USB port

    I have mentioned this problem in a couple of other threads here, but I just got some news from Apple, so I thought it might be worthwhile to start a new thread. As you can see below, I have a MacBook Pro/15"/1.83, running 10.4.7, manufactured in week 13. When I went on a trip to the "Mainland" (I live in Hawaii) last month, I discovered that the USB port on the right side of the computer didn't work properly with my Apple USB modem. While I could get a dial-up connection, I couldn't maintain it, and it would hang up within a minute or two. Everything worked normally on the left side USB port. I brought the computer into the Honolulu Apple Store, and they confirmed the problem. They also booted the computer off an external drive, and it worked fine. I wiped the drive, and reloaded everything, and the right USB port still didn't work. I then sent the computer in for repair, twice now. The first time they also wiped the drive and sent it back to me. Second time, they kept it for 2 weeks, but were unable to find a problem. Sure enough, I still have the problem on the right side USB port. However, I also discovered I could do a backup of my user folders (~3 GB) onto an external USB drive from the right port with no problem.
    Anyway, I just finished speaking with the Apple Rep, who told me there are other MBPs with the same problem, and they are investigating it. They said I should keep an eye on the Apple Support site for possible software/hardware fixes.
    Hope they fix it soon. I do want to say that the people I spoke to have always been helpful.

    Hello...
    Even though I just got this USB Modem yesterday (as I have a trip to a place with no wireless or ethernet connection), and I haven't had the chance to test things out enough, I would like to report that I have the EXACT same problem, although I did connect several times from the RIGHT-side port (and even so, it was only for a few minutes, if I connected at all).
    The LEFT port has now worked for 24 minutes straight, so, I think that that is the issue. There is a clear difference between the RIGHT port and the LEFT port, and I seriously doubt that it is the service provider.
    I will continue to use the LEFT port until I find out more about what is going on. Very strange indeed.

  • Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

    I have a Mid 2011 Macbook Air.
    Upgraded to Yosemite last week.
    Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
    I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
    After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
    If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
    I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
    I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
    I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
    I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
    I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
    Thanks,
    John

    Hi!
    I have exactly the same problem, and I can't find any solution.
    I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
    I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
    Any suggestion is greatly appreciated!

  • MacBook Pro Retina USB 2.0 devices not working in right side USB port

    4 days ago I bought MacBook Pro Retina 15".
    When I plug USB 2.0 device to right side USB port, it does not work. OSX does not recognize it, iPhone does not charge, and so.
    When I plug the same USB 2.0 device to left side USB port, it works.
    When I plug USB 3.0 device to left or right side USB ports, it works without a problem.
    Does anyone have this same issue? How did you resolve it?

    I have a similar issue with a 13" Retina. Both my ports work OK for most USB devices but the right one won't work with a USB external HD (Time Machine backup). Very consistant.

  • Right side USB port is not functional on my new Spectre13

    I just purchased a new Spectre13 notebook and the USB port on the right side isn't functionnal. I searched in different places in the system and I cannot find a way to get it working. Is this normal?

    And now the left side USB port doesn't recognise my 16GB USB key anymore. It does recognise a Logitech wireless mouse key but not my key.
    Since it works fine on My MacBook, I know the problem isn't the USB key. 

  • HP Pavilion dv6 audio stops working upon inserting headphone

    I have a HP Pavilion dv6 Notebook PC with Windows 7 64-bit Service Pack 1 installed. Almost every time that I insert a headphone into either of the two headphone jacks the audio stops functioning and this issue continues even after I remove the headphone from the headphone jack. As a result when I want to play an audio on my laptop I get an error that there is a problem with the driver/sound device. I have the latest IDT High Definition Audio Codec driver installed, i.e. sp59542 ver. 6.10.6381.0. Occasionaly, disabling and enabling, or uninstalling and reinstalling the audio driver would resolve the issue but the problem would happen again upon connecting a headphone to my laptop. I have used two different headphones (differen brands) and the problem continues. From the searches I have done this seems to be a hardware issue and something related to the on/off switch in the headphone jack so I was wondering if HP is aware of this and whether any recall has been made. It looks like there are different symptoms associated with this hardware issue. Any help with fixing this problem would be greatly appreciated.

    Hi HP-User22,
    Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion dv6 and audio stops working when inserting headphone. Here is a link to update the BIOS.
    I would be happy to assist if needed. How Do I Find My Model Number or Product Number?
    Have you tried to run a hardware test? Here is a link to do a hardware test. This will test all hardware functions.
    Please let me know.
