Hi, I have a hp envy 13 and I upload the schematic and motherboard photos. There is a short on edp cable and 40 pin socket. Schematic shows there is invpwr_b+ where the short is (pin 1+2) but I test there is ground on motherboard, you can see copper on photos. How can I repair this short, where should I connect 40pin edp cables pin 1+2 on motherboard without change socket?
