The "alt gr" key is broken on my tx2650eg. Hp Support offered to replace the whole keyboard. It's necessary to 'Pick Up and Return' my notebook. It's possible that i have to pay for the repair, because I haven't extend my warranty with the 'Accidental Damage Protection' of HP Total Care Programm. In my opinion I'm only in need of the key cap and the retainer clip. Any Hints?
