PLEASE I NEED URGENT HELP
Firstly, I noticed that the tiny light that shines when the CAP LOCK key is On stopped displaying 2 days ago but the key still functioned.
I used the laptop in the afternoon (hp probook 4540s),i turned it on this night and went to chrome, when I was typing I noticed that each time I pressed the SPACE key it will automatically add FULL STOP to my typing I pressed BACKSPACE to delete and it turned the chrome to full page, with a pop up notification at the top that I should PRESS THE F11 BUTTON TO RETURN TO NORMAL PAGE size.
I tried typing in WhatsApp to know if the problem is exclusively to chrome but it's all the same.
I've tried troubleshooting the keyboard, uninstall keyboard from device manager and reinstalled it but it's still happening.

You need to change your keyboard and if you think the problem is not from the keyboard, reinstall operating system
