I am having a problem with my connection for my power source. I had been using my laptop in the student lounge with it plugged in to the wall. Someone walked by, and caught the cord, pulling it off my lap, landing on the floor. There didn't seem to be anything wrong with it, so I didn't make an issue of it. Later I noticed that the ceramic or glazed(?) end of the plug (the yellow "coating") was chipped. It wasn't as tight while charging and over about 6 months, it just seemed to get a little more loose. Now, I can hardly get the connection to engage while completely plugged in and sitting on a flat stable surface. The laptop is not very new anymore, and I hate to spend too much money on it for repair, so I am seeking opinions.
I am not sure if the problem might be the cord, or the where it plugs into the computer. I know that it is not easy to make a guess, having not seen or touched it, but if anyone has any opinions, I would appreciate it. I don't even know if this could be something that would have developed anyway, since it is my first laptop. (For reference purposes, it is a Gateway M151x.)

Is there a electronics lab in the school where you could have them measure the voltage at the AC Adapter plug where it plugs into the computer?

Or do you have access to a voltmeter?

The proper output voltage will be marked on the ac adapter body. Typical would be for example 19 volts at 4740Ma.
You just need to measure the voltage.
If you get 19 volts as you move the wire around, then I hate to say the problem is inside the laptop.
If the voltage comes and goes as you move the wire then the AC adapter is bad which does not mean it couldn't be both in a worst case scenario./

Locally in NJ where I am it is around $150 for a DC Jack repair if the problem is internal

Thanks for the suggestion. I found out there is a program for networking and repair, so I am going to see if someone can look at the connection for me.
