Well, before, I posted -
" Hey everyone,
This is my first time posting here smile.gif About 4 months ago my laptop AC adapter started having problems - I'd had some problems beforehand with the laptop overheating and turning off, and then I started noticing it was difficult to pull the ac adapter plug out of the back of the laptop, or that I had to push it in and fiddle with it to get the laptop to realise it was actually plugged in. On closer examination I noticed the yellow ring of plastic around the metal plug of the ac adapter (the part that plugs into the back of the laptop), was tinged and burned, and the plastic of the ring was getting deformed. Then one day, the metal pin of the plug got stuck in the back of the laptop, and separated from the cable.
So, I decided to get the pin out of the back, and bought a new ac adapter. It seems to be working okay, but to my complete horror, the plastic on the inside of the pin looks a little burnt / charred already. I really don't know what to do.. I'm trying to keep the laptop unplugged as much as possible, and people are just telling me to wait and see until it gets to winter (because the summers here are very hot) - but I really don't want the pin to break again! What can I do, and what's causing this?
Thanks everyone!"

But now I'm even more despairing about the whole situation. I'm sure it's not the ac adapter plug, but rather the socket - now I'm having to jiggle the plug in the ac adapter socket at the back of the laptop to get it working. I suppose it could be something lose inside the laptop, etc.. I just dont know what to do :| The plastic on the inside of the ac adapter plug seems to be getting more and more burnt, and that seems to be making it harder for the laptop to actually acknowlege it's plugged in.

A poor connection will cause it to get hot just like a shorted connection.
If I was to run across this problem I would check to make sure the ground part of the connection inside the laptop is connecting to the plug when you plug it in.

The grounding part is the connection is the part that makes contact to the outside part of the plug.
The positive part of the plug is the part that slides into the hole on the plug.
They both have to make good connection in order to operate correctly.
If either one or both does not make good connection this will cause the plug to become hot at the point of the bad connection.

This is basiclly the way the inside of the computer looks, that is why it is very important to have the correct powersupply with the correct plug. If the inside part of the plug is correct then you can tighten up the grounding part of the plug by bending the clamp part that fits agianst the grounding part of the plug. (shown in pic.)
