My Compaq Armada m700 won't turn on. The DC Adapter doesn't have LED light so it's hard to see if that's the problem. I took out the battery and plugged the DC adapter cord in and that turned the laptop on and put the battery pack back in. It worked fine and I decided to test to see what happened when I pulled the cord out and the laptop quit working, shut off. Is the problem the battery or DC Adapter? Laptop still working when I remove battery and plug the DC Adapter cord in and it starts up and I can work on it. Should I replace one thing or both? Thank your for your help, I am not able to purchase a new laptop at the moment because the funds are not there and I am looking for a job. Hope to get a new one when I get a job.
