Bios Mods -The Best BIOS Update and Modification Source

Hello,
I have Toshiba Satellite L655-1EL, I want to upgrade current cpu (i5-480m) to (i7-720qm).
I'm tryed with i7 but no screen, so if any bios mod possible to support i7-720qm?
Thank you.

Hello,
Requested screenshot attached.
Thank you.

Motherboard in this laptop has only two phases for Vcc. So it can't boot with quad cores CPU.
