Keyboard & Touchpad Troubleshooting

    Resolution:

  • Keyboard is not working

    1. Reboot the computer by pressing and holding the power button until the unit powers off and disconnect any external devices (e.g. ext. mouse / keyboard, printer, USB-devices, etc..).
      If your keyboard works after removing all external peripherals, check every external component on failures.
    2. Press the "Caps Lock" key. Is the light of the key turning on and off?
    3. Try using an external PS/2 or USB keyboard if not already done. If it works proceed to the next step.
    4. Try to make a Bios update with the help of an external keyboard (if it is working) and check if your internal keyboard is working after this firmware update.
    5. Did some liquids were poured over the keyboard? In such case you have to bring your machine immediately to an ASP, remove the battery if it is possible and do not try to power on your machine again!

  • Keys pressed on the keyboard do not match the characters shown on the screen

    1. Reboot the computer by pressing and holding the power button until the unit powers off and disconnect any external devices (e.g. ext. mouse / keyboard, printer, USB-devices, etc..). If your keyboard works after removing all external peripherals, check every external component on failures.
    2. Verify that the correct language was selected in the "Region and Language Options"
    3. Try using an external PS/2 or USB keyboard if not already done. If the external keyboard is working properly, it is possible the internal keyboard is defective, you should visit your local ASP.
    4. Did some liquids were poured over the keyboard? In this case you have to bring your machine immediately to an ASP, remove the battery if it is possible and do not try to power your machine on again!

  • Touchpad/Trackpoint is not working

    1. Make sure the touch pad is not disabled. Try to enable it with Fn-F9.
    2. Disconnect any external devices (e.g. ext. keyboard, printer, USB-devices, etc...). If your touchpad works after removing all external peripherals, check every external component on failures.
      Verify if the error persists after a reboot of the machine.
    3. Try to connect an external mouse if not already done. (which has been verified working properly) and check if the error persists.
    4. Check the touchpad settings in the "Mouse Properties" and enable the touchpad if it is coincidentally disabled.
    5. Remove your mouse from the "Device Manager" in the "Control Panel" and reinstall it with the latest driver available.

  • Mouse cursor is moving erratically on touchpad input

    1. During heavy system load the mouse cursor could seem erratic. Wait until all applications are fully loaded or CPU intensive applications to finish and try it afterwards again.
    2. Sometimes the Touchpad needs to recalibrate itself to ensure an accurate operation. During this recalibration process the mouse cursor is wandering over the desktop for a few seconds. Do not try to move the cursor during the short time of recalibration, it will cause to intervene the process and the touchpad will try to recalibrate itself until the calibration is done.
    3. In the case the mouse cursor does not stop wandering after a short time try to disable the Touchpad with Fn-F9, if the cursor is still moving is probably a hardware failure existing. 
    4. If the cursor gets stuck on the desktop or would not move anymore after a while of working please try to disable the Touchpad with Fn+F9 wait a few seconds and reenable the Touchpad with Fn+F9 if the problem still exist is probably a hardware failure existing.
    5. Disconnect any external devices (e.g. ext. keyboard, printer, USB-devices, etc...) and reboot the machine. Check if the error persists; if not then probably one of the external peripherals is causing the error. Check which component is faulty and replace it.
    6. Try to connect an external mouse if not already done (which has been verified working properly) and check if the error persists.
