In addition to FreeBooter's excellent advice, if you're keyboard has software for it, make sure it's updated to the most recent version that will run on Windows 11.Uninstall the keyboard driver from Device Manager and restart your computer for Windows 11 to reinstall keyboard driver.
Your keyboard connection inside the laptop could be loose. I had a similar problem some time back, After a lot of tinkering with software, I finally resolved it by opening my laptop and then putting everything back properly. It was indeed a loose connection.Well, I am having an annoying issue.
Twice now, my laptop's keyboard has just stopped working. The only thing I can do is reboot. It is very annoying!!
Anyone else notice this?
