hi. i have ASUS laptop- x453m model. i just left my laptop on and when it off the screen (sleepmode) i tried to turn it on after a moment then it suddenly won't work. power button didn't work. not charging and no light indicator at all. i already went to diff technician and they said its the motherboard that has a problem. can i still fix this? or need to replace a new one? pls help. thanks
