Laptop screen only works if HDMI is connected

allnex · Aug 13, 2016

Hello. I have a strange error. My laptop only works if the HDMI is connected to a television (didn't try VGA/monitor but I guess is the same).

If I start the laptop disconnected the screen is black, but works if I plug the cable. I tried with the fn key, but doesn't work either.

The laptop is an Acer Aspire 5552 Series with Windows 10. Tried to upgrade to Anniversary Edition to see if was a W10 issue, but the problem persist.

Thanks.

OK so you are saying that the laptops display isn't working by itself and you can only access the computer if you are plugged into an external monitor, is that right?

If so, then first I would open the laptop up and make sure the cable running into the display isn't damaged, pinched, loose, dislodged or damaged. Should that not be the problem, the laptops display may well need replacing.
