HP pavilion zd8000 not powering on

HP Recommended
Pavilion zd8000
Microsoft Windows 8.1 (32-bit)

Hello, my HP Pavilion zd8000 is not powering on. I have not used it for a couple of months and today I plugged in and it does not turn on. Couple of months ago I decided to revive it for a project I am venturing in. I bought RAM, new fan, installed Windows 8.1 32-bit and then put it to rest until I would have the time to work in the project. I do not have a battery attached to it. My battery died years ago and never bought a new one. I have been using it with the AC Adapter cable plugged directly. But, like I said, I plugged the cable today and not even the front LED light that shows that the cable is connected to the laptop lights up. Pretty much, there is no signs of the laptop receiving power at all. Nothing happens when I press any buttons or when I wiggle the cable. I am wondering if this means that the AC adapter is broken? The AC adapter is the original heavy brick look like. It has a green light on, which means that is receiving power from the outlet. Unfortunately I don't know how to test the end of the adapter to see if the right voltage is coming out. I looked in you tube and google for instructions on how to test it with a multimeter, but no luck. I am hoping that the problem is the AC adapter and not the mother board. If anyone has any thoughts or can give me instructions on how to test the voltage of the AC adapter I would greatly appreciate it. The end of the ac adapter is not a common one, this is an oval shape and weird, not the little round ones like the new laptops. Thanks in advance.
