Hello all, I am having some issues with an HP Pavilion ZV5000 power adapter. I received the computer with a bad power jack on the motherboard. After replacing it, the computer ran fine for days on AC power. It still runs fine on the battery, but there is an issue with the AC adapter. When I plug the laptop in, the external power LED lights up for 3 seconds and then shuts off. It seems to be the same duration every time. The voltage tests good with a multimeter when the power cord is not plugged into the laptop, and it will provide steady voltage for as long as I care to hole the probes to it.
My question, and I'm hoping someone more knowledgeable or experienced in this area than I can help, is should I be looking to the AC adapter or the laptop itself? I really don't want to tear the laptop down again if I don't have to. I don't think the solder joints on the new jack on the motherboard are bad because I see no change by holding the tip of the plug in different positions, which should put pressure on the bad joint and cause it to make contact. I have opened the AC adapter and replaced the caps on the output; they weren't vented but they were from a suspect run of Nichicons. Other than that nothing is visibly burnt.
Any advice is appreciated!
