I have an ancient Gateway2000 laptop with a similar problem. The coaxial power jack on the side of the computer is directly soldered to the internal pwb. Over time and use, the solder joint breaks, and in my laptop, became intermittant. It's a lot of work to fix it, so I just set the computer on a table with the pwr cord hanging down to put pressure on the solder joint inside. Try slowly moving your power cord around while monitoring the charge LED on the laptop. I had to hold the cord in each place for a few seconds before the LED came on. The coaxial plug on the end of the charger cord is also a problem area; the wires inside the molded shield break eventually.
