Believe problem to be one of the Power MOSFET's, in the DC - DC circuit on the motherboard

http://en.wikipedia.org/wiki/DC-to-DC_converter

Using the HP Pavilion dv6000 series and Pavilion dv9000 series, of Notebook PC's for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

The two Power MOSFET's used; are the Fairchild Semiconductor Industries -FDS6679 - Power MOSFET, and the Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET.

Showing availability and cost. Using just FDS6679 for an example,

http://www.mouser.com/Search/Refine.aspx?Keyword=fds6679

Obsolete. Using cross reference match example,

http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FDS6679AZ/?qs=sGAEpiMZZMshyDBzk1%2fWi1qxDdW%2fXBi2qgMuZEfLVO4%3d

One dollar and one penny USD.
AO4407 is obsolete too. Cross reference match example for it, cost is 78 cents USD.

NOT stating the P.MOSFET's are used on your Sony VAIO's motherboard. Showing what a Power MOSFET looks like for this type of application, and availability/cost.

Look on your motherboard in the DC - DC converter circuit area, where the DC Power Harness plugs in.

[The AC adapter (Charger), plugs into the DC Power Jack on the laptop. (DC_IN)

For your laptop the DC Power Jack is connected to wires, that end in a male plug connector. The male plug connector plugs into the motherboard.

It is now called a DC Power Harness ]

Let's take a brief look at a motherboard example,

http://www.ebay.co.uk/itm/Sony-Vaio-PCG-6L1M-Laptop-Motherboard-A1171213A-Spares-Repair-NO-POST-/360566230317?pt=UK_Computing_Housings_Touchpads&hash=item53f36c0d2d

(Sony VAIO PCG-6L1M and VAIO VGN-B1VP are supposed to be the same)

The Main view shows up automatically, with the Top view of the motherboard.
Scroll down for Bottom and Top view.

Again there is a Main view, and this time two smaller views to the Right.
Top small view is Top view of motherboard.
Bottom small view is Bottom view of motherboard.

Looking at Bottom view of motherboard, believe DC Power Harness plugs into the Right side.
Series of Power MOSFET's are on the right side, also.

WEAR an ESD wrist strap, and have it's alligator clip attached to a good ground source.
Here is free access to the Service Manual.
You want VGN-B

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-sony

Bottom line -> VGN-A
Scroll across, click on VGN-B

Sony vaio not charging while charger plugged in


Seemingly your laptop dc jack is dead. How to confirm it? If you should wiggle your laptop charger on a position to let your laptop charge, it indicates your dc jack is loose. Either replace it or repair it. If your dc jack works well, please check your ac adapter. Maybe your charger is dead.

Replace power jack on sony vaio vgn-nw240f


Hello, this is a very simple task on this laptop. The hardest part is removing all of the screws and remembering where they all go. No removal of keyboard or mouse pad required, just the screws connecting the base cover, hd, CD drive (and under this drive once it has been removed), and under the battery...The base cover has good molded clips that hold the base on pretty securely even after removing all securing screws so try to get an area loose and starting there slowly work your way around the edges making sure you don't force an area where you may have missed a screw. Once you have the base cover removed it's fairly easy to see where the dc adapter is located, where the screws that secure it are located, and where the connector to the motherboard is located. You can buy a new dc adapter on eBay for around $12 and a quick Google search will find you a teardown tutorial/video if my description wasn't enough. I've replaced mine twice thanks to the ac adapter cord breaking the dc adapter on the inside when my 5 year old knocked it off the couch causing it to land directly on it. Don't forget to remove all power and ground yourself while working on the internal parts of computers! Have great day!

Laptop won't charge


You might need a new battery....you could try removing the battery, plug laptop into ac and restarting. Or you might need a new DC power jack. If you wiggle the cord where it plugs into the laptop, and it starts to charge normally, then the DC power jack needs replacing. http://www.insidemylaptop.com/take-apart-sony-vaio-vgn-s360p-replace-broken-power-jack/

Power socket is loose


dc jack socket for Sony VAIO VGN-FW is very easy to loose, I think you can replace the cabled dc jack, no solder work, plug in and work, see this reference page: http://www.lapdiy.com/sony-vaio-vgnfw-series-power-jack-port-connector-dc-in-cable-p-2647.html
the above item is with ground cable, it is known that sony FW uses both harnesses with or without ground cable, you can cut the ground cable directly if your laptop does not use it, or order from this page for the one without ground cable: http://www.lapdiy.com/sony-vaio-07300012492a-power-jack-port-connector-dc-in-cable-p-2782.html
hope this can help you

Power socket for sony vaio is broken how do I


On a Sony, many times the power socket is a separate piece that can be replaced. Unlike many laptop motherboards, these power sockets are a separate item the plug into the motherboard. \

Bad news is you have to dissassemble the computer to get at it.
