Broken power adapter --- Compaq Presario 700

Hi all, looking for some help.
My meighbour's Compaq Presario 700 has suffered some damage to the power adapter --- looks like someone let it drop. The connector where it goes into the back of the machine is slightly bent, but the actual connection on the back of the laptop is broken: the pins seem to have snapped off, and the adapter just goes in but doesn't grip. As a result, no power.
Now, there's no way to power up the machine, therefore no way to charge the battery, and she's at her wits' end. I believe the connection is on a card, which may be replacable. Just wondering if anyone knows if this is possible, and if so, how difficult/expensive is it? Unfortunately she can't afford to just buy a new machine.
Any help appreciated: I'm not too well up on laptops, and they seem quite tricky to work with.
Thanks!

if u can get to the mobo, i mean really taking the laptop apart, it is possible to replace or resolder the ac connector, providing that it did not already cause damage to the board.
compaq/hp site (search on model) - or here http://www.eserviceinfo.com/index.ph...rio+900+Series - provides good service manual guide that would step u through to take the machine apart. just need a bit of nerve

cheers ...

Thanks for the info. Unf I wouldn't know one end of a solder iron from another (could be quite dangerous, come to think about it!)
I was hoping that the board itself could be replaced: from what I can see through the casing, the connector is on a small board slotted into the mb, though I could be wrong. I was hoping this could be replaced, hopefully without too much difficulty...
Thanks anyway

Go here to find out the part number and price of the board.

PS: On some machines (the HP's) they have a port that a connector plugs into that will charge the laptop:

Here's an example:

Note, it seems the above link it gone.... I'd try looking around on the above site..


Here's a Notebook Expansion Base a Hp and some Compaq's.... the above link was just for the cable I think.... If you could get the base you'd be able to charge thru it (if your unit has a docking port)
http://www.techexcess.net/hp-noteboo...2-0-cable.aspx


Stay powered up: the expansion base charges your notebook while it's connected (expansion base powers from your notebook's AC adapter)


Another option is to repair your motherboard. /board that is damaged. You might want to check the for sale /trade part of the board for someone that is offering repair services.

Reparing the power connector is a common repair. I bet if you were to you'd find plenty of posts... plus people offering repair services.
