Short on +5VALWP line
eMachines eM250 KAV60 LA-5141P no power on. adapter power is good. how to deal with short on the +5VALWP after the inductor. tried supplying external 5v on the line but the supply wire gets very hot and starts to melt the insulating material. i am using an Ethernet cable for the supply wire. thanks
