  1. Keyboard Letter Not Working


    Hi


    We have a Lenovo PC with Windows 10 20H2


    At the login screen c, h, l, o, p, u, v and return key are not working.


    If the letter p is pressed this invokes the Projector SideBar its as if the Windows Key is being pressed


    The issue occurs with any keyboard and onscreen keyboard.


    If we pass the credentials through using a remote agent the user account gets logged in, and the issue still occurs.


    Initially we thought it was down to KB4598242 and removing and rebooting appear to have fixed the issue. However, the issue is still occurring.


    Keyboard drivers have been removed, drivers and windows updates are all the latest.


    Has anyone go any ideas how this can be fixed?

  3. Keyboard letters problem

    Here are the first two steps you need to take:

    • Try a different keyboard (or an external USB keyboard in case of a laptop)
    • See if the problem persists with the on-screen keyboard (osk.exe)

    Some keyboard letters not working

    Hi,



    Sorry to hear about the inconvenience caused.

    • When you click the buttons on onscreen keyboard using mouse, what happens?
    • What is the make and model number of the computer?
    • Are you using a laptop or desktop?
    • Are you using the external keyboard?

    This issue might be caused due to program conflict or hardware problem.

    Please follow the below methods and check if it helps:



    Method 1: I would suggest you to run
    hardware and devices troubleshooter and see if that helps.

    a. Press Windows Key +R, type Control Panel.

    b. Type troubleshooting in the search bar, click on troubleshooting.

    c. Click on Hardware and Sound, click on
    Hardware and Devices.


    d. Follow the steps from the wizard to run the troubleshooter.

    Method 2: Put the computer in a Clean Boot state to see if there is any software conflict as clean boot helps in eliminating software conflicts.

    Note: After performing the troubleshooting steps in clean boot, follow
    Steps from the link to return the computer to Normal startup mode.





    Method 3: Update the drivers for the Keyboard.



    Follow these steps to un-install the Graphics driver:

    a. Drag the mouse to bottom left corner and right-click on the “Start icon”.

    b. Look for the Keyboard drivers.

    d. Right-click on the keyboard drivers and click on “update drivers”.



    Hope this information helps, for further assistance please reply.
