Recently i cleaned my laptop and now I reassembled it and it wont turn on. I have Alienware m17x r2. When I press power button, keyboard and power button light up and i hear some very silent noise. Touchpad also doesnt light up. I tried to take out the battery and holding power button for 60 sec but it doesnt work.
I didnt touch display cables but i will check. Maybe I accidentaly disconnected something. I thought that touchpad was the problem since it wasnt lighted on so i connected it again and nothing happened.
