I have windows 7 HP DV4 series laptop.Its keyboard does not function on startup. I have to open on screen keyboard. then keyboard starts functioning. I dont really need to use OSK. The keyboard keeps working till I am done for the day. When I restart again I face same problem to open OSK and start doing my work. This problem started after I upgraded to windows 10. In fact I faced lots of problems in windows 10 probably due to compatibility issues with Norton360. So I have reverted back to windows 7.and am facing Key board problem. Can you please help me fix this issue
