Laptop driving me crazy!

[Aguiluz]

So my power port on my laptop is a kind of hit and miss. Sometimes it charges and sometimes it doesn't. I tore the laptop apart and check the solders on the port. Nothing. No cold solders, no cracks. I looked at the charger plug. It outputs 18V as it needs to, I twist and bend it and it still outputs 18V. I plug it in. Nothing! I checked the points on the motherboard for 18V. Nothing!

I twisted the plug 180 degrees and it worked. Then I turn it back 180 degrees and it stopped working.

I looked at the innards of the yellow socket on the board. The positive is the classic pin in the middle. The negative is ok too.

So I went for broke and chopped off the charger plug and I soldered a new one in. Bam, powered it right up. But here's the twist. Rotating it connection and turning it back reestablishes it. So I have to spin the plug into various angles to get it to work. Not to mention that the new plug gets hot. (is that bad?)

Help?

EDIT: It does not get hot. It's just freshly soldered. Silly me!

EDIT 2: It DOES get hot! Is that bad!?

I'm not sure, but my iBook used to do that. Complained to apple, got a new power cord, and it worked just fine.

Could be corroded?

Maybe a short in the cord?

Maybe a short in the cord?

That is a high possibility.

First thing I did when my laptop stop working was a new power adaptor of which you need to get methinks, then Installed a new powerjack just to safeguard myself and it's all worked fine since.

It really is spending a very small amount of money on ebay and doing it properly so it doesn't kill your laptop and it's not going to break every week, really.

Or you could go the cheaper route and replace the cord with some wire and a new plug.
