• Satellite C650 15Z two USB ports have stopped working / load

  Hi can someone throw their professional opinion on a current problem I am experiencing with my

  Satellite C650 15Z
  Windows 7

  There are 2 USB ports which are now both inoperative - there seems to be no power from them (ipad/phones do not charge) and any flash drive I insert does not appear as a drive in my computer
  and I don't hear audible alerts or message pop ups after insertion. Like I don't know what I look in Device Manager, I thought that someone may be able to help here?
  Thanks in advance

  Hello

  In Device Manager, you can try to delete and remove the USB host controller and USB hubs.
  All these devices are responsible for the functionality of USB ports.
  After you remove the USB host controller and USB hubs, restart the laptop.
  Usually the Windows operating system should recognize the devices automatically deleted after that, you can check if the USB feature is back.

• Pavilion dv7 cl6157: USB Ports do not work

  All my USB 2.0 and 3.0 ports suddenly stopped working.  In Device Manager all have beside them yellow warning triangle.  When I click on the ports, it says "cannot load the driver for this hardware device.  The driver may be corrupted or missing (Code 39).  I tried to update the drivers.  It says software found to update the driver but cannot be accessed (Code 39).  What are my options to remedy this?

  Hello

  Possibly, it can be repaired in the Windows registry, try this first:

  If necessary, reinstall the drivers, driver USB 3.0 on computers with processors / AMD chipset is contained in a single installer:

  Hi Thierry,.

  This issue does not appear with Windows that even after you perform a clean installation. So for me, it looks like a material damage. I would recommenmd get you in touch with the manufacturer of your computer and to do the repair.

  Do not hesitate to contact if you have problems with Windows in the future.

• USB mouse and keyboard suddenly stopped working

  My USB connected Microsoft USB Bluetooth mouse and keyboard suddenly stopped working today. After researching everything I could, I didall that I could find as a possible solution that has been:

  • Update of the chipsets
  • Uninstalling usb in Device Manager and reboot devices
  • Updated via Device Manager, usb devices
  • Reformatting and reinstalling Windows 7
  • Stop, unplug and allow the card mother "reset".
  • Try multiple ports
  • There is no 'connect' button on my mouse so I can not sure try this
  • Replace the batteries in my mouse
  • Obviously both devices have been connected
  • Updated the software for the mouse

  I have tried literally everything I could think of or read previously and I am out of options. Oddly enough however, after reformatting and reinstalling windows, my USB storage device is found and is working, but the keyboard and mouse are not. Please don't bother not suggest anything I listed above, I obviously already tried and found no chance.

  Update
  I have solved my problem. For later use, if anyone has this problem and no other solution seems not work; That's what I did.

  I bought a USB 2 ports PCI card and installed in my computer, then go back to Windows XP. While my original front and rear USB ports still recognize a flash drive, they do not recognize the keyboard or USB mouse, make ports PCI card. I had also updated ALL the updates of windows on the site, not the auto update available on the desktop. Although I don't know the cause, I am certain that somewhere, something was is altered by the hardware or software, and my default USB ports do not recognize mouse or keyboards.

  Another piece of knowledge in case anyone is interested; I use a card mother gigabyte s-series and my nvidia video card GeForce previously is no longer recognized in the port, it would cause my computer go into a State of hibernation and the monitor would go into "Analog Power Saving Mode". The only solution was to spend a friend with my video card. (Its graphics card is a GeForce 9800 GTX, mine was a GeForce 9800 GT. No reason why it should make a difference.) According to me, even if my computer is less than two years old, I was sold a bad mother. I read online cases in other forums for technical support of people having the same problem. Gigabyte motherboards stop random ports for no known reason.

• resolution 2560 x 1440 has suddenly stopped working. 1080 p now the max option available

  I have 2010 macbook pro (el capitan) and ASUS H257HU monitor that supports the resolution 2560 x 1440. Until yesterday, I was able to get the full resolution, but suddenly it has stopped working and the max resolution I could get was 1080 p.

  I tried to reset the smc and NVRAM, but that did not help.

  In safe mode, I followed the suggestion of apple and was able to get resolution of 2560. But it reboots the machine back to 1080 p. Hold down the option key and clicking on the option scale does not display any resolution above 1080 p.

  I've tried searching and following some recommendations, but no permits.

  Restart the computer and enter views sometimes give 2560 option, but clicking on it makes the screen turns blue and then it always comes back to 1080 p, with no options available in the dialog on the scale. The System Preferences dialog box hangs for a few seconds.

  Someone at - he fell on the same issue and found a solution. I don't know why he suddenly stops working, while still being able to work in safe mode but not in normal condition. I tried to remove the profiles as well.

  With bootcamp (win 7), the display works fine with 2560 x 1440.

  The connector I use is screen Mini DisplayPort.

  All proposals/solutions will be very well received.

  Hello there, moths.

  It seems that you are having problems to select the resolution you want on your external display from ASUS. Great job with the troubleshooting, you've done so far. The following Knowledge Base article offers strong information to look over and review, as well as links to some additional troubleshooting content:

  Get help with graphical problems on external displays connected to your Mac.

  Before you start

  You can solve many problems of display by updating the software on your Apple devices, cables and adapters. If you see an image on your screen, look for the software updates using the Mac App Store:

  1. Connect your external display and Apple video cables or cards that you use with it.
  2. In the Apple menu, click App Store.
  3. Click updates in the window of the App Store.
  4. Install OS X updates or firmware are listed.

  If you use a display, hub, extenders or adapter not made by Apple, check with the manufacturer for updates that might be available.

  If you try to connect a screen 4 K or Ultra HD TV with your Mac, make sure that your computer meets the requirements for the use of these external displays.

  If your firmware and software are up to date, or if you don't see the image on your screen, try the steps below for your specific problem.

  {...}

  Check the connections

  Check the connections on your Mac and external screens:

  • If you use an Apple laptop computer, try to connect the AC adapter.
  • Make sure that the power cable from the external display is connected correctly and that your display is enabled.
  • If you are using a Mac Pro (end of 2013), make sure that your screens are plugged into the right ports.
  • If you use a hub of display, Cabinet or "KVM", try to connect the video cable from your screen directly to your Mac instead.
  • Unplug the video cable where it plugs into your Mac, then reconnect to reinsert the connection.
  • If you are using a video card, unplug the video adapter on your Mac, then reconnect to reinsert the connection.
  • If you use multiple video cards to connect your screen (the cards are "chained"), testing connection of the screen by using a single adapter if possible. Some video cards may not be linked together. For example, a mini DisplayPort to DVI adapter may not be connected to an adapter DVI to HDMI.
  • If your screen has more than one video connection, see if you are using another connection on the display works. If possible, check if you use a different view or a different adapter works.
  • Try using another cable that you know to be in working condition. Check with the manufacturer of the screen to make sure that you use the cable they recommend.

  Detect your display

  If you use an external monitor, sleep and wake your Mac to check for connected screens:

  1. Press the power button on your computer to standby, or choose the Apple menu > sleep.
  2. Wait a few moments, and then press a key on your keyboard or click your mouse or trackpad to wake up your Mac.

  If you use more than one screen, and you can see the image on one of the screens, you can also use the preferences monitors to check the connected screens.
  

  Adjust video settings

  If there is no image on the screen, try adjusting the brightness or contrast of the screen. If there is still no picture or image appears torn, or scrambled, try selecting a different video resolution in system preferences. Adjust brightness

  • If you use an Apple Display Monitor, press the key to increase brightness your Apple keyboard. To adjust the brightness of a secondary screen, press Control + F2.
  • If you use a view that is not made by Apple, see the documentation that came with your monitor to see if it includes built-in controls to adjust the brightness or contrast.

  Change your display resolution

  1. In the Apple menu, choose System Preferences.
  2. Click the display icon.
  3. Click default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the ESC key to cancel the change.
     

  If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.

  If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

  Search for software third display

  If your monitor only works when your Mac is started in safe mode, and related to the software display is installed, check with the developer of the software for updates, or try to uninstall temporarily.
