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)

 

Disabling laptop keyboard

Hi,

Thank you for posting your query in Microsoft Community.

As per the description. Let me help you in resolving the issue.

I suggest you follow the steps below and check if that helps:

• Press Windows + X and select
  Device Manager from the list.
• Find Keyboards in the list of devices and click the arrow to expand it.
  
• Right-click on the internal keyboard and click Disable. If there is no Disable option listed, click
  Uninstall.
• Click File>Exit. Your laptop’s internal keyboard should now be disabled.

Note: If you had to choose Uninstall instead of Disable in step 4, the keyboard will be automatically detected and re-installed if you ever have the Device Manager scan for new hardware for some reason. If that happens you’ll need to repeat this procedure
in order to uninstall it again.

Hope the information helps. Please let us know if the issue persist and we will be happy to assist you further.

I will try that... do you think I have complete access to replace the monitor cable without dismantling the laptop from step 1? *Eek!
Tbh it's a bit scary.
