@hanzla10607 pretty indicative of a failed keyboard. You will need to replace it (or use a USB keyboard). Download the service and maintenance manual for your computer [http://h10032.www1.hp.com/ctg/Manual/c06367535.pdf|from here] Page 64 tells you how to do it as well as the part number. Biggest issue here is that the keyboard is "integrated" with a bunch of plastic welds etc. into the top case. That means you have to replace both of it.
