Keyboard malfunction on Swift 3 SF314-51-31EH Notebook shortly after a Windows 10 update

Hi everyone,

Some keys stopped working just 6 days ago. Prior to that the keyboard was fully functional. Keys such as: 1,3,], T, J, Q, -,  and a few more are not working at all.

We tried:

1. Uninstalling the KB driver in Device Manager then restarting the system.

2. Updating Windows 10 to the latest.

3. Looking for a KB driver and other new drivers on the laptop support page, (None available).

A specific Win10 update was done just 2 days before this problem started:  Microsoft KB5023696. Could that have caused the issue?

We'll be grateful for any help on this matter.

    Sometimes a simple system restore will fix the issue.. 

    Try windows x
    click on power shell admin or command prompt admin 
    type rstrui
    chose an earlier date on which your computer was working fine  
    click on next, finish, yes
    It will restore your computer to an earlier date 
    if you get an message - system restore not completed - click on close 
    It will show you all the icons..
    Try and check whether it is working now ..

    If it is still not working then we have to do a refresh and reset

    click on start - settings - update and security - recovery - reset this pc - get started 

    or 

    on start - type here to search - type reset this pc - click on reset this pc on the top  - click on get started 

    It will show you keep my files and remove everything
    chose keep my files 
    chose the account - type the password - click on local reinstall - click on reset 
    It will be in progress.. 
    login to computer and start using the computer. 
    If it is still not working 

    click on start - settings - update and security - recovery - reset this pc - get started 
    chose remove everything 
    click on local reinstall - just remove my files - click on reset
    It will be in progress

    Note:

    If you do refresh ( keep my files ) -  all your personal files like pictures, music , documents , videos  will still be intact.   Only the applications will be lost

    If you do reset  ( remove everything )  - you are doing a factory default.   It will become like a day one computer.    It will wipe out everything and take your computer to day one like a new computer. 

    You can also do the recovery in an alternative way..

    There are two alt keys on the keyboard.  If you look at the bottom row of keyboard you can see the one on the left side of space bar and the other on the right side of space bar.  The alt key on the right side will be looking like alt, alt gr or alt car.  Turn off the computer.  Hold the alt key on the left and tap f10 continuously.   It will go to repair mode. It will show you chose an option, continue, troubleshoot.   If it is not going to repair mode, turn off the computer.  Turn on the computer.  Hold the right alt key ( alt gr or alt car or alt )  and then tap f10 continuously.  It will go to chose an option continue and troubleshoot..

    It will show you chose an option, continue, troubleshoot
    Go to troubleshoot  -  click on reset this pc
    click on keep my files  ( only applications will be lost )   chose your account and type your password   - click on local reinstall  - click on reset
    It will be in progress 

    If the keep my files option is not working 

    Go to troubleshoot  -  click on reset this pc – click on remove everything – click on local reinstall – just remove my files – click on reset 
    It will reinstall windows. 

    If the just remove my files is not working..

    Go to troubleshoot  -  click on reset this pc – click on remove everything – click on local reinstall – Fully clean the drive – click on reset 
    It will reinstall windows. 

    Note: You can also go to chose an option , continue , troubleshoot by holding the alt key + tapping f10  or alt gr + tapping f10 on the keyboard while turning on the computer.    Once you see the troubleshoot option, you can stop tapping the f10 and stop holding the alt key.    Then you can try the keep my files and remove everything ( just remove by files and fully clean the drive ) by following the steps which was mentioned above.

    tried it, no luck. I even wiped the cable with 99% alcohol

    OK thanks for this advise.

    If I reinstall Windows, is that better?

    Not too likely to fix it with a Windows reset, but always possible. Make sure you have your data backed up before trying it. If it doesn't work then that help pin it down to hardware, which will involve a keyboard replacement, which isn't cheap.
