Power problems with a Compaq Presario C700

\015 I have a Compaq Presario that worked find untill one day after the battery went dead. I plugged the AC addaptor in it but the ring light around the plug-in didn't even turn on. The laptop would not run at all. First I tested the AC addaptor with a voltmeter and it is working fine. Then I tried unplugging it, taking the battery out, and holding the power button. That didn't do anything to help my problem. So I then took the whole laptop appart. All i really did when I took it appart though was clean the dust out of the fan and unplug the power plug in from the mother board and plug it back in. So then, just for the hell of it I plugged in the AC addaptor and the ring light around the plug-in flashed. So i fiddled around with it and I noticed that if I held the battery so that it was just barly before it clicked into its slot the right light around the plug-in would light up. So i held it there for a little-bit and then pushed the battery in so that it clicked and it seamed to be working. I let it charge for a while and then booted it up and I really thought that my magic touch fixed it. I should have known that my luck wasn't that good. After a while I shut it down and let it charge for a while but when I came back the right light around the plug-in was let again off and the darn thing would boot-up. I tried fiddled around with the battery again but that didn't work this time. Any idea what the problem could be?\015

Answers :

Sounds to me like a broken connector on the socket on the motherboard.check, ,or a broken wire at the plug end, check, or the like, or the battery is not making contact as you discovered. Meter the PSU, and wiggle the plug, and socket and see if it makes and breaks connections.
