Heyy, sorry if this post is not in the right section, but I recently bought a new 4400maH battery for my Dell inspiron 9300. It works like a charm... when It charges. I have to wiggle the power cord around in the back of my computer to get it to charge. Help?
 
You have a bad power jack port on your laptop, you will need to send it to get repaired. Or its possible you have a bad power adapter, but most likely its the port on the back of the laptop.
 
Can you tell if the jack is physically loose in the computer? As John said, it's probably a bad jack where the solder breaks loose from the board.
 
It does not seem to be physically loose at all, when I wiggle the power cord, it does not move the actual input. Is there a way to fix it without sending it in? I have completley opened it up before to replace a graphics card, and although it takes a while, it is pretty easy.
 
All you really have to do is resolder the points around the power plug. It's really not that difficult. Just find where they connect to the board and touch the soldering iron to them. You can even add a little more solder to help secure the connection, just be sure nothing crosses and you don't burn anything by holding it on too long.

Something else, I've even put some padding and such around the top of the plug if possible. You know, something to help secure it. Just be sure nothing's too close to the board where it might get hot/catch fire :P
 
Thanks for the detailed reply, but I do not own a soldering iron. Where could I buy one, and if I do end up getting it repaired, could someone like best buy or futureshop do it? And how much might it cost?
 
Take a look

I opened up the computer again, and took picture of the power input.

The other side of the board is where you'd want to look to see if it's loose.

Those aren't very pretty solder joints though...
 
So, Im still confused, it does not seem to be loose on either the outside or on the board it self, so where would I solder?
 
Wow...that really doesn't look good... There may even be some damage inside the plug rather than how it connects to the board. You may need to find a replacement plug... If you want to try and fix that one, I'd probably try and do is gently rub off some of the burnt area with some emery cloth, but be VERY careful not to scratch the board or any nearby components. Then add a very small amount of solder to the top (what you pictured) three connectors and the bottom.

While the case is open, you may want to plug it up and see if you can see it wiggle any. Don't force it too much and break the solder, but confirm you did reseat everything.
 
Removing the old jack can be tricky and if you get the MB too hot it can damage it.. I use side cut pliers snip the cage down the middle then unsolder it then snip the jack to expose the leads then unsolder it... makes it easier and elimates the chance on getting the board too hot when removing... installing is the easy part...
 
So, If I understand you guys right, I should remove the old plug, and replace it with the one hjahmad recomended? Hpw would I got about removing the old one? Im really a rookie when it comes to laptop power.
 
heat the solder from the underside, careful not to let it spread to other connections. when its hot, you'll feel is loosen then pull it out. and put the new one in the same way.
i dont like this design, when i did it on my old ibook, i just have to buy this small circuit board to replace. no soldering or anything since it was a seperate board from the main board. it just attached with one screw.
 
probably quite a few
not all are solder points that you see. some are just to holes to keep the thing lined up properly. my guess is around 4. but i really dont know
