My acer screen blackened

[nellywille2012]

I have this Acer aspire 4520notebook. when ?I turn it on the keobard lights all light up, but the screen remains black, this happened before but somehow I turned off and on from the "Power on" button and it worked, but for 2 days now nothing happens, screen still remains blackened. What might be the problem? and any way of fixing it without spending money?


I need help here . Thanks

Did you accidentally switch it to the VGA port for an external monitor?

No I didn't connect any VGA ports for external mirror, not sure how to do it even...

Try to press <Fn> + <F5> and see if something happens. If that doesn't work ask a friend to connect his Monitor to your Laptop.
