how to reset the BIOS hardware on Lenovo Y560?

[Feliks3563]

Anyway, when I put the new windows refused to work a discrete graphics card , and the software installed, but the card was in the device manager as a standard VGA adapter. And accordingly , the laptop was on the integrated graphics.
In the BIOS have to work on a discrete piece of iron , resulting in the monitor goes off completely. "Machine " includes boot Windows, but the screen is blank.
Attention to the question !
How can hard reset BIOS on this laptop ? Jumper or get there a connection from what ....
