It's 19.5 volts with green light on untill i plug it into the computer, at which time the green pwr light on the pwr supply goes off and after another reading it's zero. after unplugging from laptop and wall, and plugging back into wall only, not the laptop, pwr supply pwr light goes back on. as soon as the pwr adapter is plugged into the laptop the power light cuts off. this is the same with or without the Batt installed.

It sounds as if the motherboard has a short. Not uncommon today as I've found broken jacks, staples and worse inside laptops. If the output of the adapter was zero I would say that's it but it looks the right voltage.

Motherboards are expensive enough to write it's time to start shopping.
