I have an acer v3-531, I just recently been given the laptop from my mum who used it for a year. It had loads of programs on it that would always reappear after I had deleted them and would pop up all the time when i was playing games etc. So a week ago I restored it to its factory settings and it was working great then today i went to switch it on and it wont go on!!!! The blue lights up on the power button and stays on but the screen stays black and there is no noise of a fan etc. I tried it with a different battery from my boyfriends laptop and it still does not work (both batteries worked great on my boyfriends laptop) Anyone know if or how i can fix this!?
