Socket 1156 has broken pin....

Hi...I have an Asus P7H55-M Motherboard and the 1156 CPU socket has one broken pin ....Now I know that this may not stop it from working in fact I once had the required schematics that allowed me to identify each individual pin and what purpose it was for.....Sadly I cannot find them....Can anybody please guide me to a source of these ...which will enable me to identify what the broken pin is used for.....
Thanks...Hk
