2 days ago out of nowhere my G15 5520 decided not to turn on. I plugged the charger in and it still had the led telling me that it's charging. I suspect it had something to do with sleep mode (i only closed the laptop but didnt shut it down, ik u should turn it off but i was very tired and i just closed the laptop and left it like that overnight). I've been charging it for a while and it still doesn't turn on. Doing any sort of activity (like pressing a key or the power button) just makes the charging light blink once (white charging light is on, disappears for a second, white light is back). I've already tried hard resetting as well and nothing. Any help?
