Keyboard problem (certain keys do not function)

Hi

Im running Ubuntu 10.04 desktop on my HP Pavilion dv3-2093 laptop. Now a couple of week after the installation of ubuntu 10.04 certain keys no longer give any output. I've checked the keyboard setup, and it seems to be right (Norwegian, Norwegian). The keys that dont work is: T-P, H-Ø and 7-9. 

Im running dual-boot with Win7, there everything works fine. Ive also tested these faulty keys with a usb-keybord, with the same result.

What is wrong? Anyone experienced the same problem?
