Windows 10: Keyboard, touch pad and onscreen keyboard stopped working

My hp pavilion 360 convertible keyboard stopped working. I uninstalled and reinstalled windows 10, then the touchpad and onscreen keyboard stopped working too. I cannot type at all. Help!!!

Keyboard and touch pad not working after using as tablet mode

I have a toshiba convertible laptop, I was using it in both laptop mode and tablet mode. Suddenly after converting from tablet mode to laptop mode the keyboard and touch pad stopped working in windows. The keyboard is functional and working in bios I am able to change the options in bios but when it comes to windows only the function keys are working to change the system settings. The touch pad is also having the same issue.

 

Onscreen Keyboard

How are you bringing up the keyboard?

For me, I right click on the Taskbar and select Show touch keyboard button, then when I click on that I get the Onscreen keyboard at the bottom of the screen and it looks like this:

 

onscreen keyboard

I have a Dell Latitude 7220 tablet using Windows 10. The device is currently in tablet mode and the onscreen keyboard will not deploy. The keyboard icon is visible in the bottom right hand corner, but nothing happens when you click on it. I have gone in the keyboard settings and checked use your device without a physical keyboard--Use on screen keyboard. In addition, the box under ease of access-keyboard-use onscreen keyboard is also checked.

A floating keyboard is available with the win+ctrl+0 keys, but I am wondering why I cannot have the icon or have an auto pop-up when typing is available. Any suggestions would be wonderful.

Thank you.
