Hello,
I have a Lenovo 80LX running Windows 8.1. Everything has been working fine until today when the screen shut off while I was editing a document. I figured the screen had died, so I connected the laptop to my TV via HDMI and everything came up fine on the TV, so I was able to save my work. Just for kicks, I went to the display options and selected to duplicate my screen on the laptop and the TV, and the laptop screen came back to life. I tried extending the screen across both monitors and this worked as well. However, when I selected Primary screen only, the TV went blank (as expected), but the laptop screen went (and stayed) blank as well. Both screen came back on about 15 seconds later (because I didn't confirm that I wanted to keep the new settings) and I've been running it with two screens on since.
Googling for an answer has been difficult because it mostly points me to people who's laptop screens are broken and are looking to just use a second screen. Maybe I didn't search right, but I'm hoping someone here can help.
So, to sum up, my laptop screen only works when a second screen is plugged in and duplicating or extending my desktop.
Thank you,
Tehko
