Tablet is not starting

I was trying to upgrade to Windows 10. When I restarted for the first to do the initial upgrade from a flash drive it didn't boot pass the bios. It kept going back to it on every restart. I got tired of it and I just closed the lid and from then on I can't start it anymore. Everything time I try to boot it now I just get a black screen and just the light beside the camera goes on. If I hold the power button then it goes off. I tried voting it by holding power and volume +, power button and F6, power button and del, every possible ways I could find and I always get the same results; just the light beside the camera is on and nothing else. Could anyone help me out with this?
