Use a BGA Rework Station like the above.

Going to use a good Southbridge chip from another motherboard, that is the same?

Yes.

Removing a good Southbridge chip is redundant.
Buy one? MAY be possible.

By the time you have a BGA Rework Station used, the cost may equal, or exceed the cost of a replacement motherboard.

Oven / Torch /Heatgun method? Yeah right.
Temporary repair at best.

The HP Pavilion TX2530ee Notebook PC uses Integrated Graphics.

Uses AMD ATI Radeon HD3200 graphics.
Which is an AMD ATI RS780G graphics chipset,

To digress;

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The Integrated Circuit, or chipset, for graphics; is a graphics chipset, or properly known as the G.P.U.
Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU

The chipset itself, is in the middle of the green, square small circuit board.
The small circuit board, is used to connect the chipset to the motherboard.

The AMD ATI 780G graphics chipset is mounted to the motherboard, with a BGA surface mount.
Ball Grid Array.

To explain the BGA surface mount let's compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.

The processor has 478 contact pins sticking down out of the bottom.
The Socket 478 processor socket has 478 matching socket holes,

http://en.wikipedia.org/wiki/Socket_478

With a BGA surface mount, there are no contact pins on the graphics chipset.
There are no socket holes on the motherboard.

In place of the contact pins are Solder Balls as you have seen.
In place of the socket holes on the motherboard, are Copper Pads.

The graphics chipset is set into place over the motherboard, with the Solder Balls lining up on the matching Copper Pads.
Then heat is applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset, TO the Copper Pads.
(Which in turn of course, solders the graphics chipset TO the motherboard )

IF, the cooling for the graphics chipset is Inadequate, the graphics chipset will overheat.
Constant overheating, will partially melt the solder connections that were made.

When the laptop is turned off the solder connections will re-solidify.
This causes Cold solder joints, and a poor contact of graphics chipset to motherboard.
(Solder joint = solder connection)

Could be the graphics chipset just needs to be re-soldered to the motherboard, and better cooling for the graphics chipset, implemented.

Hence why the long 'tutorial' above.

Unless of course the chipset is obviously burnt. Visually checked, and seen burned.

PROPERLY re-solder, or replace, requires a BGA Rework machine.
(BGA Rework Station)
Here let me show you a BGA Rework Station in action,

[Most of the time the shop you take it to, does not have;
A) Proper training for the techs to perform this
B) Proper machine

Want to just replace the motherboard due to the above, and also brings more $$$$$ in their pockets ]


Now who?
Depends on where you are located. I bet this guy can do it,

The "media test failure" message usually occurs when it tries to boot from LAN instead of the hard drive. It most likely says something about an Intel/Marvell PXE Boot Agent. If it does, then you'll have to disable the LAN Boot ROM in the system setup boot configuration.

you can contact with the dealer where you buy it,
here is the address of inlet Bangalore
Intel Technology India Pvt. Ltd.
#136, Airport Road,

Good luck, do rate if got help

hehe, you cant swap gpu chips on laptops but I can
but I have super infra red equipments and 10 years of experience in bga reworks.

from the picture there is space for go 7400 in the empty bga 0.6mm type to go there but can you find someone to do it?

1: Check wether the on/off button on your power supply is turned to on.
2: Check your cables. Try switching with those from other pc's.
3: Check wether all the connections from power supply to the mainboard/ram/video/harddisk are OK.

Hope this helps,
Yannick
