I have an hp eliteboiok 8730w,all of a sudden the bios would need date etc resetting on evey boot,i thought no probs just change the coin cell,upon inspection the cell holder was hanging from the mainboard on the battery ground side,i need to know where to jumper/connect a wire to make the bios work as normal,therefore i need a schematic+ the boardview if poss,i cannot see any remains of a pad or track so need another ic etc to ground the coincell too,thanks in advance.
