HP pavilion sound and wi-fi button

i realize a lot of similar threats like this has been posted LONG BEFORE I DO, but anyway i have this laptop of 5 years old which suddenly the wi-fi and volume button's light is mixed between blue and red and its like broken.

this actually happens to me 3 times

The first and second time i have tried to do hard reset, hold the power button until died, remove battery and AC and fan etc and hold power button for 30 secs and start again which works fine. However for the 3rd time doesnt seems so, due to some circumstance, i place my battery on the other room and since according to my knowledge hard reset doesnt actually really needs battery i just hold power button for 30 secs and start it and WOW THE BUTTON IS STILL UNUSABLE. so i decide to restart the hard reset,turn off,remove ac adapter,remove portable fan, hold 30 secs and this time put back the battery and ITS STILL DIDNT WORK. i have try hard reset several times as well as f10 and even stupidly system restore but it still didnt work, now is there anybody who can tell me what should i do? should i go to repair just for something like this? since this happens to me before i feel weird if i need to go to repair just for this, well unless if there really is no other option. once again, can someone please tell me what should i do? thanks
