My HP pavilion dv6000 series is having an issue with multiple keys on the keyboard. When I push the following, this is how the keyboard responds:
•Space bar = space with a period added
•Up arrow = the letter O
•Down arrow = 9
•Enter = L and enter at the same time
•Backspace = backspace and F11/full screen mode in web browser at the same time
•Letter O = the letter O and up at the same time
•Letter L = L and enter at the same time
•Period button = period and a space added
•Number 9 = 9 and F11/full screen mode in web browser at the same time
open device manager.
To do so, click on start > right click on computer and select properties.
select Hardware and then select Device Manager.
There, u will see keyboard option, expand that and then right click on the option listed under it.
Then select uninstall.
Now restart the notebook to get the keyboard drivers reinstalled.
Now, if the issue persists, the updated BIOS installed for your notebook.
If still the issue persists, u need to replace the keyboard.
