Lenovo Yoga 700 black screen after bios update

I updated my bios for the laptop and the laptop restarted and the screen was black but laptop was powered on. Also keyboard backlighting is on. I turned it off and then on hundreds of times and held the power button for 30 secs but still nothing.

Re: Lenovo Yoga 700 black screen after bios update

This happened to me but my laptop was out of warranty and it's been at repair center for 2 months. They say I have to pay despite it being their fault because I have no serial number . I have my receipt from best buy,doesn't  count. There's no way of finding serial number because blow update broke motherboard. It's been a vicious cycle.
