No.
At least not in replacing a graphics card. More to follow towards the end.
The ATI RS780M is a graphics chipset. The GPU is mounted on a small square circuit board. The circuit board is mounted to the motherboard, via a BGA surface mount. (Ball Grid Array)
Chip and Chipset are slang terms for I.C.
Integrated Circuit,
http://en.wikipedia.org/wiki/Integrated_CircuitThe Integrated Circuit for graphics, or graphics chipset, is a G.P.U.,
http://en.wikipedia.org/wiki/GPUThe GPU used is an ATI RS480M.
Example of an ATI RS480M chipset,

The left side is the Top view.
On the Bottom view shown on the right, note the Solder Balls.
These are on the end of contact pads, which are flat on the end.
The flat end is also gold plated, before the solder ball is mounted to it.
To explain a BGA surface mount;
Compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.
The bottom of the Processor has contact pins. 478 of 'em.
The processor socket has matching socket holes. (478)
With a BGA surface mount there are no contact pins, nor socket holes.
The chipset to be mounted has Solder Balls on the bottom.
The motherboard has matching Copper Pads. (Which are also gold plated)
The graphics chipset is set into place on the motherboard, with the Solder Balls lining up with the Copper Pads.
Heat is then applied at a specific temperature, and length of time.
The solder balls melt, which solders the graphics chipset to the copper pads.
(Which in turn solders the graphics chipset to the motherboard)
Proper method of removing, and installing a graphics chipset, using a BGA surface mount, is to use a BGA Rework Machine.

There is a method to increase the graphics 'power', however.
Involves using a desktop computer PCI Express graphics card, a desktop computer power supply, and and adapter for attaching the PCI Express graphics card to the laptop.

B)
http://www.hwtools.net/Adapter/PE4H.htmlYes, cuts down on portability somewhat. Everything can be put in a carrying attachment, but the power supply does have to be plugged into AC power.
