I removed the battery from my laptop, waited, and I still have the problem. I have a HP Probook 4510s. Not a single key on the laptop keyboard works.

I held the right shift key down for 20 seconds, and now the keyboard is working fine. Any idea what happened>?
Expert:  Sibu replied 7 years ago.

I solved the problem by going to Microsoft support center, and then I found a page titled
"Windows keyboard shortcuts overview".

At the bottom of this page you will see the following:
Windows keyboard shortcuts overview

Accessibility keyboard shortcuts

Press To
Right SHIFT for eight seconds Switch FilterKeys on and off.

Once I did this, by keyboard worked normally. None of the keys were "stuck". I'm not sure how I got into the mode where none of the keys worked, but this was the solution to the problem.

OKay

Right shift pressing for 8 second will disable filter keys only not the whole keyboard

any how ...I am glad that the problem is now solved
