How can I replace south bridge chip on asus

Scroll down, click on the Red -
Take a few minutes to view the IR 650 demo video

Use a BGA Rework Station like the above.

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


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.

Nvidia GeForce Go 6150

Scroll down to the first larger photo.
(Under the green - Exhibition: )

This is a bottom view of the motherboard. Look to the right of the white Socket S1 processor socket.

That is an Nvidia NF-G6150-N-A2 chipset,

Uses a BGA surface mount, to mount it to the motherboard.
Ball Grid Array surface mount.

To explain the BGA surface mount;

The AMD Turion 64 X2, model TL-56 processor for your laptop, uses contact pins on the bottom.
The pins go in the socket holes of the Socket S1 processor socket.
(638 pins, 638 socket holes)

With a BGA surface mount there are no contact pins, nor matching socket holes.

In place of the contact pins are Solder Balls.
In place of the socket holes are Copper Pads on the motherboard.
(They are gold plated)

The chipset is set onto the motherboard, with the Solder Balls lining up on the Copper Pads.
Heat is then applied at a SPECIFIC temperature, and LENGTH of time.

The heat melts the Solder Balls, and solders the chipset TO the Copper Pads. (Which in turn solders the chipset TO the motherboard)

Also another method used to remove, or reflow a chipset.
Posted ONLY for reference. Not advertising for this tech, nor website,

(Also check out his;
HP Pavilion dv2000 blank screen fix.....
and, HP Pavilion dv9000 blank screen fix......... )

Note how this tech PLAINLY states;
1) The heat MUST be uniform all around the chipset.
Cannot be any 'cold spots', or 'hot spots'.

2) The temperature MUST be at a specific temperature, and checked all around on the chipset.

3) When using the type of heat source the tech is using, the heat MUST be slowly withdrawn away.
This allows the chipset to cool slowly, and helps prevent cold solder joints.
(Chipset to motherboard)

You better be GOOD to do what he is doing.

The best method hands down though, is to have it done with a BGA Rework Station.

Hp tx2530ee

The HP Pavilion TX2530ee Notebook PC uses Integrated Graphics.

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

The Left side shows the TOP.
The Right side shows the BOTTOM.

The Right side shows the -> Solder Balls.

To digress;

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

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

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,

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,

Intel L440GX sever motherboard, I just installed it and keep getting a medi failure message. I have ckecked yhe hard drives and the cables they work fine in other systems. Can you help?

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.
