Hi, I've been experiencing a problem with my Lenovo Yoga 700 laptop where the screen remains permanently black. My computer will turn on, or so it seems, but nothing appears on the screen. I've tested many potential solutions to try to fix this issue, which I'll list shortly, but unfortunately nothing I've done so far has worked.
This issue first appeared this past Monday on June 18th, 2018. I happened to be using my laptop at the time, when the screen suddenly went black. As far as I can remember there was no noise when the screen went black. I tried to get the screen to come back on by increasing the brightness and pushing the screen backlight button, but neither worked. So I forced shut down my laptop by holding the power button in, and then shortly restarted it to find the screen was still black. However, when powering on the laptop the fans work, the keyboard lights come on (and I can toggle them on and off using "FN + Spacebar", tho I've discovered that after the laptop has been "on" a little while, say 5 minutes or so, the keyboard light gets stuck on and "FN + Spacebar" will no longer toggle it off), and the Power Button Light on the side of my laptop turns on.
Since then I've researched the issue for Lenovo laptops, and luckily most forum topics I've found people were able to find solutions to their issues. Nothing I've read has worked for me tho.
Here's what I've tried, that I can remember:
Off the top of my head this is mostly what I've done to troubleshoot. I've also tried increasing the volume using the keyboard keys when I turn on the laptop, just to see if I can hear any log-in sounds. While the screen is black I've tried to log-in to my computer too (just waited a while to ensure bootup would've normally completed, then entered my password and hit enter), hoping the computer was functioning correctly besides the screen. As far as I can tell nothing happens.
At this point I'm guessing this is some hardware issue, but I'm hoping someone else might have some other ideas I should try--especially because there is stuff on my laptop I would really like to not lose that I stupidly didn't have backed up elsewhere, and I'd like to avoid sending in the laptop for service to avoid losing that stuff.
Thanks for any help.

Unfortunately I was not able to figure out what was wrong At this point I was pretty convinced it was a hardware failure of some kind, and ended up just giving up on my laptop. I still have it though, so if you ever run across a solution that works for you, please let me know!
I'm sorry I couldn't be of more help. Good luck fixing your laptop, hope you have more success than I had.
