Dell Latitude E6520 Corrupted bios

[ironsniper1]

Hey everyone i have a Dell Latitude E6520 with what i believe is a corrupted bios as it will not post, i cannot get into the bios or boot menu,

i have a programmer that i was going to try and read the bios from a working e6520 and seeing if i can flash it to this one that is messed up

however i cannot find any information on what bios chip it uses or where on the motherboard it is located, does anyone have any advice i can try?
