Im reballing this board and got a lift pad. Can anyone tell me if it's ground? Or point me to a schematic to know what to do.


Thanks!

if u have onboard graphics you dont need it .if u have discrete graphics u should remake trace cuz it is used for dedicated chip.
m1 pin is used for pci-e lane

that chip is the northbrige RS780m with incorporated graphics.
just solder the chip without that pin because in your board model it is NOT used
