• Help, please! 17 "Macbook Pro - USB no longer works

  I have a Macbook Pro 17 "2010 edition and I am facing a strange problem which is really harmful to me.  I'm a DJ and use this machine for the job, and she was miss you.

  In other words - when I plug an 85w adapter this Macbook, I have a noise in my helmet and my USB ports stop working intermittently.  It causes my controller DJ disappear and reappear constantly in the sound settings in system preferences and makes it so I can't play and music.  If I unplug the adapter 85w, however, everything works fine and I get no sound in my headphones.  I called my local stores and they have never seen this problem, with a store saying that it will need a new controller for a $500 card.

  Can someone please give me some clue as to what I could do to fix this?  I tried to reset the SMC but no dice.

  Have you tested your power on another Mac adapter or tried a different power adapter on your MBP?

  Ciao.

• USB no longer works on Satellite T230

  HelloW,
  I use the Satellite T230 (Windows 7 64-bit) for about a month.
  Once one of the USB ports stopped working. USB-drives are not recognized at all, a mouse - the note is simply a repeating beep. That USB port doen't see a USB key during startup.
  Everything works with a different port.

  I tried the system recovery, update the BIOS. Nothing helps.

  I am really angry and don't know what to do.

  Thanks for any help

  Hi Yu_1,

  > I tried system recovery, update the BIOS. Nothing helps.
  System recovery means that you have already reinstalled Windows from Toshiba disk recovery and HARD drive recovery?

  If so, I think that you have tried everything you can do and it looks like a hardware malfunction :(

  So as next step, contact a service provider allowed in your country and ask the guys for help. They can solve your problem. I think that it s mainboard issue because the USB ports are set on it.
  If your laptop is under warranty, the repair would be free :)

  Here is a list of all the FSA:

• USB no longer works after that the BIOS flash to ABCN74WW on the new Z70-80

  Hello

  I started with the installation of Windows 7 on my brand new Z70-80 which worked well, worked USB 2.0 ports.

  After flash BIOS to ABCN74WW USB ports do not work any longer. I already tried soft reset BIOS by unplugging the power supply and the battery by pressing the power button for 20 seconds. USB ports are still inaccessible after that, a USB flashes for a moment, mouse LED is lit but no laser and no operation at all. Even when I start any new installation of windows.

  Is it of any known issues with this version of BIOS? Can I cancel the flash BIOS?

  Kind regards

  I do not remember on an option to backup the bios and certainly did not do. In any case, the upgrade from windows to 8.1 solved my problem...

• Put Windows 7 on hp envy 17 Quad t - now USB no longer works!

  Hello

  I just got a HP Envy 17 Quad t, which came with Windows 8 on it.  I'm not a fan of him, so I installed Windows 7 instead.  After installation do not work many things, as expected, but I was able to install drivers windows 7 for them and got all the functions that have been lost so far, I have noticed to rework except my USB ports.  I tried two different drivers of these boards with no joy.  If someone has the right driver, so I can get USB up and running would be extremely appreciated!

  Thank you

  Max

  OK, was able to fix it myself after a few hours of really messing around.  (I'm not a computer guy, so this announcement to other experts).

  First of all, I went on the Intel site and updated the chipset driver, once again.  This fixed the problem of Bus SM.

  Second, I had to find the driver 5227 RTS for the card reader from RealTek PCIE, which I couldn't find on the site from RealTek but through multiple searches on Google using the portion of the id of material only up to '... in the end 5227."it's strange, because another driver RealTek PCIE card reader worked before Win7 updates, but that even the driver did NOT work thereafter.

  Then he got even more bizarre, to me at least.  The I need drivers were all there in Device Manager, no more yellow triangles, but I plugged my external hard drive on a USB port on the right side of my computer and nothing.  The way in which my office is set up I really only use this side.  Exasperated I tried the USB port on the left with another device.  Alto!  It took.  I had to plug my external hard drive in the left side first and could then unplug and install it on the right side and it worked.  No idea why it would need with one side first, then don't work both sides.  I waited a long time when I plugged it on the right side first before trying the left where he recognized immediately, then immediately recognized on the right after that.

• Satellite Pro S300 - USB no longer works

  Hello
  I have a 6 month laptop Satellite Pro S300-100 and running Vista 32 bit. He got 4 USB slots, 1 handset that works on the left side and 3 USB2 connectors right side and these 3 suddenly stopped working. I tried different connections, memory stick, external drive, USB mouse, but they are all dead.

  I've tried deactivited and operated them, no change. I checked the ports and the response of the system are that they are involved.

  I had a similar problem earlier on a Tecra 9000 a few years ago and the replaced the motherboard.

  Anyone has a solution, please?

  Hello!

• Built in camera Chicony USB no longer works on laptop Satellite A200

  All of a sudden, the built-in in my laptop Satellite A200 Chicony USB webcam has stopped working - it was going very well about 6 weeks ago, but now it's as if he has actually disappeared from the laptop. The camera does not even on devices such as equipment manager - there is no single category of imaging devices (unless I am also connected to our printer/scanner). It is also not displayed in 'scanners and cameras' folder in the control panel. But the software (Toshiba Camera Assistant software) is still there. Weird.

  When I start the computer first, or at other times try to start the camera, an error message appears that says:
  * "webcam driver open fail. Restart the computer or the camera. "

  Before you tell me to download and reinstall the drivers, let me tell you what I "ve tried so far:"
  1 restart the computer (obviously)
  2 downloaded the driver for my model on this site and variously has tried to repair, replace and finally uninstalled and reinstalled the. IT IS NOT THE DRIVER!
  3 unplugged my wireless USB mouse and restart the computer (I read on another thread that it sometimes interferes with the camera)
  4 tried to get the computer looking for new hardware - he couldn't find it.
  5 tried a system restore, where it was linked to a recent update - I tried this using three different restore points system, and none of them could not be completed.

  Help! necessary technical assistance
  Thank you

  All that you have done is just.

  In all this history it's strange this webcam is not listed in Device Manager.
  In my opinion, you should do a final test to check the operation of the equipment, if you want to install the OS by using recovery DVDs.

  With own factory and OS preinstalled settings, you can check the operation of the equipment and see if the cam will work or not.
  If the problem will be the same I'm almost sure it's related to the faulty webcam.

• Click on the magic mouse no longer works on iMac

  Hey,.

  Today my mouse Apple Magic click stopped working on the iMac.

  I can move the cursor, but do not click on anything - right/left click does not work. Also, no swipe gestures don't work.

  The mouse batteries are fine, no new hardware has been installed, no secondary magic mouses.

  The battery settings page options are ok.

  I've tried disconnecting bluetooth mouse service and the pair, but still nothing.

  Also tried cmd + alt + p + r for restart, but nothing.

  What could be the problem? Is it software or hardware related?

  I use El Capitan. Thank you.

  You have another computer to test on, or a different mouse to check your results with the wandering?

• Satellite Pro L20 USB ports no longer work

  Hello

  A little bit ago, I experienced a few problems with my Satellite Pro L20. After he brought to life, I found out that the USB ports no longer work.

  Things I've tried so far:

  Reinstall the chipset drivers
  Update the BIOS.
  Ensure USB is enabled in BIOS
  Uninstall and reinstall the USB controllers via the Device Manager.

  

  The USB ports no longer work and I ran out of things to try. Any suggestions?

  Thank you

  Hello

  If possible, try to install the operating system with recovery media. On this way, you will have to factory settings. It's the best test you can do. If the problem persists, it may be a malfunction of the equipment. Sorry but on this path is not easy to tell what the problem may be.
