Acer Aspire One worked fine the night before for my wife. Went to use next day. No indicator lights & won't turn on. Plugged in charger, still no charging light. Tested charger with multimeter, measured just little over 19 volts. Did continuity check from charger plug on Acer to pins that connect to battery. Both were good. Assumption needed new battery. Recd new battery, installed and still have same problems. Any other solutions?
