I have an HP G71 laptop that just up and quit working recently. The lights that normally indicate that it is charging aren't even lighting up anymore. It's done this once before and after taking the laptop apart I finally got it to work again, but it seemed really random. I didn't feel like I had actually fixed anything, it just started working out of the blue. Now it quit working again. I currently have the laptop dismantled and I'm testing various things. My first question is should the AC adapter have power on the laptop end at all times or does it send a signal when you press the ON button and open the gate for the power to come through?
