The most likely cause is that the keyboard needs a new battery in it, inserted on the underside. After that it may be that the small keyboard comms dongle in a USB port is not making proper contact. Pull that out and insert it a few times.
It's possible there is a mechanical problem with that key (broken, dirty).
But just in case you also use a usb keyboard with the laptop make sure that you did not disconnect (the usb keyboard) with the number lock engaged. If so you can either use the virtual keyboard to disengage the number lock or reconnect the usb keyboard and disengage the number lock. Then check if the problem is fixed when the usb keyboard is disconnected.
I had the same problem and no help from HP Tech support. They had system for week and climed that nothing wrong. When I got it back from HP and it still rotates constantly with no reason. Then I deside to replace laptop keyboard and to my surprise this took a care of BIG problem. No screen rotation I have ever experienced.
By replacin dirty or defective keyboard I solved this problem.
in my opinion.your boards ps2 and serial port are not woking properly.(there may be short on pins) if u have U S B card u can stall in pc slot of you board. where u can connect usb key board/mouse and other deviouse.
