Keypad mulfuntion-miss-match

The problems that are still pending have to do with the keyboard. The buttons that are not responding or their response is wrong are f9, left left arrow, 4, 7 and 0. The numeric buttons are located into a separate keypad. Since we tried a lot of solutions I decide to take the laptop into an HP service center. I will update the topic. Thank you all for trying to help me.

Hi guys,

i took the laptop from HP service center and keyboard has been replaced.
Everything is ok now.

For a strange reason Ricoh media card reader was not recognised for once more even with the correct drivers installed (from HP website). I installed the drivers again and also this problem solved.

Thanks for your help!
