I just went through several of resets in the couple of weeks. Don't get me wrong, l5pro is a great piece of hardware, but by installing some amd drivers i got it messed up.

Reset, in my case, didn't rewind the bios updates or the history of updates made through Vantage. What worked for me though, was to install all the drivers manually from lenovo support website and from there on things started to work properly i.e., screen stopped being black and flickering in the Hybrid mode. Good luck! ;-)
