• 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.

• Two of the four USB ports on my laptop has suddenly stopped working!

  My laptop (HP Pavilion) has a total of 4 ports USB (two on the left side) and two on the right side all of a sudden my laptop developed this problem, two ports USB on the left side of the laptop no longer works... They didn't stop working completely, because I can still charge my phone via the ports, but they do not detect any storage device I plug into them. The other two on the right side work perfectly... I checked my mobile device manager and the defective thing only seems to me pointed out under "other devices", where the driver for 'Fresco Logic' hub USB root is not installed... it shows "the drivers for this device are not installed (Code 28)" Please, this could be the problem and where can I find the driver?

• 13 x 2 Pavilion: pavilion 2 x keyboard suddenly stops working

  Suddenly, my keyboard doesn't work after a cold start. The touchpad still works so I am able to move the slider autour, but none of the keys on keyboard activity. All about the Tablet seems to work from a tactile point of view. Reading another post on this forum suggested to uninstall HP System Event Utility, then reinstall using the link provided in the solution. However, the installation was interrupted due to the incompatibility with my system.

  I've recently upgraded the operating system of Win8.1 to Win10, but returned to the time where I ran out of memory on my 64 GB ssd. I did a week ago and everything worked fine except that it seems to take more time to do a cold start or restart. Not sure if this is related or not.

  HI @cyrm,

  Welcome to the HP Forums!

  This is a wonderful place to find answers and information!

  You have the best experience in the HP forum, I would like to draw your attention to the Guide of the HP Forums.

  Learn how to post and more

  I understand that your keyboard does not respond.  Why did you move to Windows 10 but returned to 8.1 of Windows due to lack of space on your SSD 64 GB.  Now your (virtual) keyboard edge works very well so you are able to navigate, but the physical keyboard does not respond.

  Have you checked the connections during the docking of the keyboard to make sure that they are aligned and course?

  After return to 8.1 Windows do you have all your Windows updates?

  Did you run HP Support Assistant for HP updates?

  When it is connected if you check device manager is the recognized keyboard and if so is there any mistake about it?

  If you connect an external keyboard work?

  Hello

  First of all, must know that the laptop should run fine without the battery with AC adapter plugged.
  Even if the battery is defective or empty, the plugged AC adapter should feed and you should be able to turn on the laptop.

  In case this isn't possible, I guess electronic power supply failure.

  However, you might try the following workaround solution:
  Try to propel upward and for the laptop without the starter battery.
  Then go to Device Manager and uninstall the following entries under batteries:
  -Battery composite Microsoft
  -Battery method to check compatible ACPI Microsoft

  Reboot the laptop.
  Turn off again and insert the battery.
  Power on the notebook and check if the device should work correctly.

  Of course, it also would you recommend to test the laptop in the framework of another good and tested the battery.

  Umair salvation,

  Please provide detailed information about your question. I appreciate the step by step troubleshooting, and pain that you have taken to resolve your problem. However, there are a few steps more that we can try to diagnose the root cause of the problem.

  I would be grateful if you can provide us with the following information to help us better understand the issue.

  1. Are you able to connect any other wireless device to the same network?
  2. Are all the lights on the Modem/Router Green?
  3. Have you tried to connect your HP laptop with wired network? If so, was the same result?

  Problem with the random disconnection of a wireless network can be triggered for a variety of reasons. To find out the exact cause of the issue, I would recommend that you run the network troubleshooter utility.

  Network convenience stores

  This problem can occur if authentication enable IEEE 802. 1 X for this network checkbox is enabled. If this box is checked, but there is no server to authenticate the connection is interrupted. If you turn on the wireless network connection, it disconnects again after a short period.
   
  Method 1: Disable IEEE 802 authentication. 1 X

  To disable authentication IEEE 802. 1 X, follow these steps:

  • Click Start, type ncpa.cpl, and then press ENTER.
  • Right click on your wireless network connection and then click Properties.
  • Click the wireless networks tab.
  • Under preferred networks, click your wireless network, and then click Properties.
  • Click on the Authentication tab, click to clear the authentication enable IEEE 802. 1 X for this network
  • Check box, and then click OK twice.

  Method 2: Disable the IP assistance service

  • Hold down the Windows key and type R, type "services.msc" (without the quotes) and press enter
  • Scroll down to the IP assistance service, right-click on it and select Properties
  • In the drop-down list box that says "Automatic" or "Manual", set it to disabled and then click 'apply '.
  • Then click on "Stop" to stop the service from running in the current session
  • Click OK to exit the dialog box.

  Method 3: update the Firmware on the router

  Download and install the latest firmware for the router, in case the steps above fail to resolve the problem. If your router is Netgear, then you can follow the steps below.

  NET gear 3700 firmware update

  Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

• Satellite A30 keyboard suddenly stopped working - how to remove and reinstall?

  Hi all, n00b to laptops and first post. OK, I usually build and repair desktop computers, so much easier to win the centimeters!
  My daughter turned on his laptop A30 last night and only 2 keys worked. Tried to restart and go into the BIOS but could not. Tried to start in safe mode, only the top and bottom of work therefore impossible to select Safe mode... doh. Guess it must be a harware issue.

  Restarted in Xp an open upward Notepad... this time, about 5 keys working. Reboot, 3 keys etc etc.

  How to cable Ribbon to make sure it is placed correctly. It is common for a keyboard to fail in this way and it is easy to get a replacement?
  At the mo, have all the screws that I know, battery removed, DVD rom and hard drive. Seems to be held towards the middle and the back. Don't want to force and break something else!

  TIA.

  Yes, it s very useful information and it s great fix you yourself.

• Satellite L300 suddenly stopped working - new motherboard needed

  My L300 Sat suddenly stopped working the other day.

  It kept freezing, then nothing. So I kill disked the HARD drive and tried to re - install Windows (XP).
  During the installation, he threw a message that some internal components had been installed incorrectly and has to be reinstalled.
  I was told to remove the memory cards and reposition the.

  It does not work. I thought that maybe the HARD drive was damaged, so I set up a new and started to reinstall Windows.
  Once again, same message. One of my colleagues at work suggested that the motherboard was probably U/S.

  So I've been trawling .net to find a replacement. Laptop computer out of warranty! I am told that some other mothers numbered series will work with this laptop. I really want to get a motherboard to find sound never go to work! My unit has a number of SPS to: V000138330.
  I am one with an SPS of offered: V000138390.

  Any ideas? This one will work?
  And if this is the case, it will give me the feature I used to enjoy?
  Sorry for the long history of sobbing.

  All the advice accepted with gratitude.

  ANDY-N

  Hello Andy

  Sorry, but can you tell us more about your laptop? What model do you have exactly (L300-xxx)?
  You have the European model?
  At your warranty valid for laptop?
  Maybe I've misunderstood something, but why you want to swap motherboard if the warranty is probably still valid?

• 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.

• Spectrum HP convertible x 360: right-click (for the context menu) has suddenly stopped working.

  Hi SergeyPov,

  I see that you are having problems with your fingerprint reader on your laptop. I'd love to help you.

  You mentioned that you also updated the BIOS. After doing that you did that the fingerprint reader is always enabled in the BIOS?

  Another option would be to possibly check the connections related to the fingerprint reader. It may have a bad contact, or it is also possible that the Board is defective. See the link below that can help checking the connection.
