I'm attempting to repair this very old laptop without any schematics as it has been impossible for me to find one. The laptop has no power whatsoever when plugged in. I've tested the charger cable and charger port and the Voltage was good. When i moved on to the module in question one of the three contacts i tested had no V, the upper right contact i haven't tested because my multimeter doesn't fit. Are any of the contacts in this module suppose to have 0 V?
