I have an HP 17-e153sa laptop running Windows 10.
Recently a few of the keys stopped working and so I purchased a replacement keyboard. I replaced it quite easily, switched the laptop on and typed in my password with no problem. When it gets into Windows however, the keyboard stops working and just beeps with every keypress.
I have put the original keyboard back in and the same thing happens - nothing types, just beeps.
I have also plugged in a USB keyboard and the same thing - only beeps.
I have tried updating the keyboard driver but it just tells me the correct one is installed.
Does anyone have any ideas why the keyboard works fine at the login screen but fails once Windows loads?
