Default Function Keys not working in HP Pavilion tx2500z
I have a HP Pavilion tx2500z (model: KD436AV) laptop with Windows 7 64 bit OS installed. Since last few months, I am not able to use default function keys (F1, F2...F12) and other keys at the top row of the keyboard, including Pg Up, Pg Down, Home, End, Insert, Delete. However, all the Action Keys available on these keys are working without pressing Fn Key (e.g. Sleep, Brightness, num lock etc). I get same Action Key behaviour even after pressing Fn Key.
It looks like, somehow system is locked in action key mode and I am not able to come out of it. I tried to upgrade Bios (currently on latest F.0F version) and also tried to disable the Action Key mode in BIOS, but Action Key mode is not available in BIOS of this computer. Even to enter BIOS, I faced problem because F10 key was not working to enter BIOS setup. I had to connect external keyboard to enter BIOS.
I am disperately looking for help to come out of this situation. Any help will be greatly appreciated.
Thanks in advance.
