Windows 11 and Keyboard Failure in Touch Screen Convertibles

[DVDR_Dog]

You know those laptops with a touch screen that can configure themselves as a tablet?
I have an old Inspiron 3147 configured that way only the on-board keyboard only has a few working keys sometimes. I thought it might be a hardware issue but I opened it up and checked all the connections and they looked OK
So here's where it gets interesting. I was out with my GF and some of her friends and found out her BF is having similar problems with her ThinkPad. Now being a fanboy of ThinkPads anyway, she has contacted Microsoft and Lenovo and they have thrown their hands up in the air and shaked their collective heads.
Anybody have a clue what might be taking place? It's obvious that Windows must be stuck in tablet mode. On my Dell, I connected a USB keyboard and it works fine. I am at a loss, any clues?

Are any of the keys stuck? In many cases with this kind of activity, it can be several keys that are stuck. My laptop did this once and after blowing the keyboard out I then turned the laptop upside down wile holding it that way I smacked my hand flat on all the keys many times then fired it up, and it worked, and eventually the bad key(s) showed themselves, and then I took the key out cleaned it good snapped the key back in and VIOLA.

The other option would be to remove the drivers for the keyboard, reboot the system, and see if that solves it for you. Otherwise, the keyboard may have gone bad.

That’s actually a great trick! Thanks for sharing!
