I have an Acer Aspire 7520-5757 from 2007 that does not show anything on the laptop's monitor when it is turned on.
When I connect it to the TV via a VGA cable, it shows fine on the TV, yet the laptop's monitor is still blank. I tried right click desktop > screen resolution, but it only reports "generic non pnp monitor" as the only monitor present.
Now the main problem is that I googled a few solutions a few months ago (letting the battery drain out, holding the power button, etc,) and the laptop's screen started working normally again. When trying to plug the laptop to the TV again via VGA, the same problem started happening again and now I can only do stuff while looking at it from the TV. Would the best thing to do just try what I did a few months ago and hope it restores itself again?
Tried Windows + P, and pressed enter on computer only, and all it does is refresh the TV's screen. Running on Windows 7 as well if that's needed.
