Hi my laptop is having a blonde moment was working then 1 wasn't working. Then it wud do ¹11111111111 etc all by itself. I turned it off and now keys asdf and lkj not working.. Iv tried sticky keys and filter keys and turning them on and off. Also removed battery and switched off for 60secs. Still not helped... Any ideas or is it a repair job, or throw it thru the window and get another one !!!
