I have a Compaq CQ62/HP G62 Notebook I'm trying to fix. It looks like a power related problem because when I plug it in to the AC adapter to the DC jack on the laptop, the side LEDs do not light up.
I tried wiggling the AC adapter into the DC jack, no good. So I took a multi-meter and I tested the AC adapter (input 10-240V/1.7A AC, output 18.5V/3.5A DC) and it comes out with the correct output voltage (around 18V-19V).
I took the laptop apart and I wanted to test the DC jack to see if that it is just not sending any power to the motherboard. However I'm not sure how to check if it is dead or not. There are 7 pins to the DC jack (3 on one side, 4 on the other). I cannot find a technical or spec sheet for this specific jack, so I don't know what is the output of these 7 pins.
If anyone knows what kind of outputs I should be seeing from these pins, I would greatly appreciate it, and it will help people from jumping the gun and going ahead and replacing the DC jack or their motherboard if they run into a similar problem like mine.
