Keyboard and touchpad stop working

Hi everyone.
I've used my HP Mini 2140 Notebook PC for about two months. Two days ago, while I was working, the keyboard and touchpad stopped responding so I couldn't do anything. The computer kept "working" though. The computer won't go into sleep-mode when I try that; it just fades out the screen and hangs. Since then, this has started happening at total random.
I've tried this across two installations of Vista Home, and have uninstalled/reinstalled device drivers. I noticed that whenever this happens, the laptop's fan accellerates to what seems like full blast, and keeps going like that until I force the power off.
I've tried unplugging the AC adapter and battery, holding the power switch to drain power from circuits and booting up again, both with AC only and battery only. Neither of these things helped.
Wondering if anyone has seen or heard of a similar problem? Very frustrating.

Have EXACT same problem! Only my keyboard and touch pad freeze up after I have let computer run without touching it for several minutes!
Have no problem if I continually use keys or touch pad!
Have extended power saver times to over 5 hours with no help!

  • Windows 8.1 Onboard Keyboard and Touchpad Stopped Working.

    After upgrading to Win 8.1 my keyboard and touchpad stopped working suddenly.  They both worked fine for the entire Windows 8.0 release.  When I upgraded to 8.1, they both worked for about 3 months.  Then what started happening is the computer
    would freeze during the startup process.  
    Now they both don't don't work.  But a USB powered mouse works.  So with a USB powered mouse and the on screen keyboard I have been troubleshooting.  I have removed the drivers from the device manager, reinstalled the drivers, searched for
    driver updates etc.  Nothing works. 
    Can someone please point me in the right direction.  PC is kind of useless at the moment.

  • Keyboard and touchpad not working

    Good day My keyboard and touchpad stopped working all of a suuden, and I need help. My computer is Toshiba Satellite E55 A-5114, this has happened to me before but only the touchpad stopped working and it fixed whenever there was a system update, now I've updated the system and installed the recent drivers and still not working, any ideas?

    There appears to be an epidemic. My guess is that a Windows update which changes a driver causes it.
    So turn off automatic update and inspect them one-by-one. They are offered on the second Tuesday of each month.

    I install only those marked Important or Critical. In particular, stay away from those which change a device's driver. Get driver updates only from Toshiba.

  • 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!

  • Starting problems, computer freezes, keyboard and mouse stop working

    Hi can anyone help? My powerbook has just stopped working, rarely starts, when it does keyboard and mouse stop working after a while or even before i am able to login. At one point I was getting a grey screen with the words, memory access invalid???? Please help...
    powerbook G4    

    power surge could have damaged something inside, or it maybe unrelated to the problem.
    PowerBook can get hot if there is some short circuit inside and power flow is disrupted, also it's possible that the fans are not working properly.
    as a guess, it is likely either hard drive or logic board problem.

  • Keyboard and touchpad not working after Windows 10 update

    after udating windows 10 on my probook 4440s keyboard and touchpad not working. if i press a key for 10seconds the key then shows up in the screen. and touchpad is worst. it freezes all the time barely moves. but with usb mouse it works fine 

    It's known that installing Windows from an external DVD drive on a Mid 2013 MacBook Air causes that the keyboard doesn't work after finishing the installation. The fix is to install Windows by using a USB drive. See > http://support.apple.com/kb/TS4599

  • Laptop keyboard and touchpad not working in Windows 8.1

    I just upgraded my S875-S7248 to Windows 8.1 last night. At first, everything seemed to be fine. However, this morning, the keyboard and touchpad had stopped working, and nothing I've tried has fixed it.  After some research, I figured out how to open the Device Manager, and the both devices are showning the infamous yellow triangle. When I click on the device, I see the message "Windows cannot start this hardware device because its configuration information (in the registry) is imcomplete or damaged (Code 19)". Both devices are PS/2 devices, and I have tried uninstalling and reinstalling the device, and updating the driver, but to no avail. In addition, I've run the Toshiba Service Station driver update, but it doesn't retrun any new updates either.
    So, short of unstalling Windows 8, what can I do to fix this?
    Solved!

    Hi rmikereese
    I had the same issue - but luckily you dont have to uninstall Windows 8 (at least I didn't need to)
    Running a system restore should bring your computer before you installed the "critical updates" from Toshiba.  Fortunately I had a usb mouse already installed (because like you, my touchpad was also not working)
    1.  Restart Computer and Sign In
         Note: I had to use the on-screen keyboard option found on the Ease of Access found at the bottom left of the screen
    2.  Right Click on "My Computer" (aka "Computer" aka "This PC") and click on Properties
    3.  Click on System Protection (3rd option on the left menu)
    At this point a new System Properties window will pop up already on a System Protection tab
    4.  Click System Restore...
    5.  Choose restore point --> I had an option for "Windows Update" which was a "Critical Update"
    My computer reset the registry and my touchpad and keyboard began working again!
    When Toshiba tells you that you have Updates (Toshiba Support Driver)  IGNORE IT!
    Hope this works for you!

  • Macbook air with 10.10.1 keyboard and touchpad stop responding after login screen

    Keyboard and touchpad works only at login screen.
    I have tried all the PRAM and SMC. reset stuff.
    Safe mode, repair etc. Creating another account is not helped either.
    I am also using 10.10.1 with macbook air.
    I have also called the apple tech support and no results!
    And this is obviously a software bug from so called robust yosemite!
    Same here!
    Macbook air built-in keyboard/trackpad only work at login screen

      You may have to take the computer to the Apple store to have it checked out.

  • Blackberry Curve 8520 keyboard and trackpad stopped working suddenly!

    This morning when I was texting on my blackberry I noticed when I was pressing the s button it would press the a button as well. Now for some reason, the a button, which is also the lock button stopped working. I switched my phone off and took out the battery, switched it back on and now it won't light up unless I am pressing all the keys repetitively for about a minute or two. Sometimes when I do get it to light up, it won't let me select anything. Does anyone know how this can be fixed? Its definitely not water damaged and it's out of warranty (I just bought it a week ago from family believe it or not!) Thanks.

  • HELP:  Keyboard and Mouse stop working

    I plugged a 4GB flashdrive into keyboard; received low power notification; plugged it into computer instead; it loaded on desktop, HOWEVER, keyboard and mouse no longer work - shut down computer for 5 minutes, still not working, unplugged and replugged in connections; removed flashdrive, shut computer off for 30 minutes; still does not work. The only positive thing, I have a laptop so I can ask this question. All the files I need are on the other computer, however. HELP

    Hello! If the usb ports tripped out you'll have to reset the pmu. With all the external cables (usb/firewwire/monitor/a/c etc) unhooked press the pmu button once then reconnect and restart. Below are a couple of example of the pmu location. Tom

  • Satellite 5200-802: Keyboard and touchpad dont work

    Hi everyone.
    I was hoping someone could help me with a problem I'm having with my Satellite 5200-802. The Keyboard will not work evn though it shows in device manager and report it as working fine. I have updated the BIOS and tried a lot of other basic stuff so any suggestions would be greatly appreciated.
    It may be worth mentioning that I also cannot get my touchpad driver to register.
    Many thanks.

    Hi
    Do you get an error message or do you have any bed signs on the screen?
    Can you use the keyboard to access the BIOS?
    If yes then the keyboard was recognized and works!
    If you cannot use the keyboard running OS then I would recommend to delete the keyboard device from the device manager and to restart the notebook.
    After new OS reboot the keyboard should be recognized again.
    But I think that you will be not able to access the BIOS.
    Due to the fact that the touchpad does not work too, I presume the hardware is faulty or there is no connection to the motherboard. Maybe a lose cable
    Maybe you should check this. But note; if you have no experience contact the notebook technicians. Bye

  • MB starts and the keyboard and touchpad wont work, i can enter through vnc

  • Keyboard and touchpad do not respond temporarily

    Hi all!
    While working on my Macbook Pro mid 2010 (Mountain Lion) the keyboard and touchpad sometimes don't repond. Everything else on the Macbook seems to work as usual, e. g. the power button works and I can see how the logfiles are updated on the console. Currently this problem occures about one time a week
    When I close the lid, the Macbook goes to sleep and when I open the lid again, keyboard and mouse work as before.
    In the logfiles the only that sounds to coorespond to the problem is:
    AppleUSBMultitouchDriver::validateChecksum - 512-byte packet checksum is incorrect
    But the time when it occures doesn't correspond to the time when keyboard and touchpad stop responding.
    SMC and PRAM reset did not solve the problem. Maybe I have to mention that the logicboard was replaced 2 month ago and can't remember that htis problem accured before.
    Any help is appreciated.

  • Windows 8.1 install crashed my keyboard and touchpad

    I attempted to install 8.1 last night having forgotten about the warnings. Had the black screen of death this morning. After rebooting Windows reverted to 8.0. But now my keyboard and touchpad arent working.  Says the ps2 compatible drivers arent
    working. Every reboot and driver update I try does nothing. any help would be greatly appreciated.

    keyboard and touchpad arent working.
    Sounds like a laptop?  Which model?  Is there any alternate input you can use?  Touch?  USB for wired or wireless?
    Can you at least use your keyboard when booting?  E.g. get into the Command only boot?

  • Keyboard and mouse not working correctly after installing Windows 8.1

    I was forced to upgrade my computer to Windows 8.1. My keyboard worked fine until the sytem did a reboot. Numbers on keypad stopped typing and letters were being capitalized when the caps lock was off and the numbers across the top will only type the symbol above the numbers. 
    I looked up this problem and it seems I need to enter UEFI settings and disable Intel XHCI mode. When I get into the UEFI settings I cannot make any selection from the startup menu. Both my keyboard and mouse stop working. 
    Any suggestions?
