i have been asked to fix a Packard bell easynote ts44hr laptop, it does not show any indication of power. no lights at all. but if i plug the charger in i can definitely hear it drawing current. i have it disassebled on my dest right now but i see no blown chips. i see 2 red glass tubes on the underside near the battery socket labeled PD1 and PD2 and those looked cracked on the inside. possibly dead fuses?
