Hi I think I have just accidentally bricked my W500i as I was updating my tablet via windows update. I remember ticking the Bios Update. After the restart it display nothing at all.
When try accesing boot menu via Power+Vol Up+Win Button+F2 it will cause to beep!
Tried all the solutions below but still no avail, how should I proceed guys? Really want to use back my tablet as its just less than a year or two old 
My warranty ended last 2 weeks, is there anything I can do?
Tried all the method of hard reset here:

But none of those are working
