Outer cylindrical metal shell is the Negative connection ]B) Next check the DC Power Jack. (The jack on the laptop where the AC adapter plugs into)With the Battery removed, see if you can wiggle the center pin of the jack. Any perceptible movement means a problem with the DC Power Jack. Fortunately the DC Power Jack for this series of Notebook PC's, has a DC Power Jack Harness. The jack is mounted to a small removable circuit board, that has a wiring harness attached to it, and the harness plugs into the motherboard. No soldering required,

http://en.wikipedia.org/wiki/Power_MOSFETNow let's talk. See how the FDS6679 and AO4407 use the D2PAK surface mount?
http://en.wikipedia.org/wiki/File:D2PAK.JPGThey use J-leads for connection. The J shaped flat leads that come out of the body of the P.MOSFET. In the above example there are two.The left view shows a Top view, the right view shows a Bottom view.Talk about easy to unsolder, and solder.Just make sure when installing the new one/s you use a Clip Heatsink on each J-lead, as you solder each J-lead to the motherboard.
http://www.radioshack.com/product/index.jsp?productId=2103242Use Desoldering Braid, (Solder Wick), to remove solder. Desoldering Tool, (Solder S-ucker tool), is for the birds.To conclude:1) Bad AC adapter - You replace2) Bad DC Power Jack Harness - You replace? FOUR DOLLARS AND FIFTY CENTS, plus shipping, and tax.Shop?$100 to $1253) Bad Power MOSFET -You replace? Cost of .032 Rosin core solder, rosin flux, small flux brush, 25 Watt soldering iron with No.2 chisel tip, Desoldering Braid, and P.MOSFET/s.It's One Dollar and 1 cent, for a FDS6679 from Mouser, plus shipping, and tax.It's about $70 to $150 for a motherboard, depending on where you buy it.And that isn't including the $125, or so for labor.(Very few real techs left. Instead of diagnosing, and replacing those cheap P.MOSFET's, they would rather sell you a motherboard.Easier for ***** in a repair shop with little to no skills, and also more coins, $$$$$$$)That's my summer vacation, and now back to you David............For additional questions please post in a Comment.Regards,joecoolvette
