My macbook pro with retina display cannot power on after software updates

I have launched the software updates a few hours ago, and then the mbpr said it would restart after downloading all the required updates (~1.39G).

And soon, the mbpr appearred to restart and then shut down. Of course, it didn't restart anymore, not even power on.

And now, I CANNOT power on the machine anymore, not with the power button. And even with control+shift+option+power, I still can't power on this stupid thing! I wonder what happened. After searching on google, i found myself to be the first one with this problem.

This mbpr is my first mac-based pc, which is a disaster to me. I need to handle something very important and hand it on tmr, i dun have a backup but just leave it on my new mbpr!!!! And now, i needa re-do it all on my old win 7 which i now find more reliable than mac os, at least i can remove the battery and i can power on the machine anyway.

BTW,

May i know how i can power on the mbpr for emergency use?

Can i have refund if im extremely unsatisfied with this stupid thing (it's still within 14 days upon arrival, but i'm in hong kong, not united states)?
