15 R3, not turning on after BIOS update?

Hello, I have had a Alienware 15 R3 for over three years now. It works very good with some minor issues. Recently the keyboard didn’t work and I replaced it now that works fine too. Today I installed the new bios update like an. The computer just turned off while it was updating. Now it does not turn on at all, no matter what I do. I took out the battery too for thirty minutes as it was suggested so much on the internet it still doesn’t seem to work. Can someone please help me with this?
