Your laptop uses Integrated Graphics.
Another term used for Integrated Graphics is OnBoard Graphics.
ON the motherBOARD.
This means the graphics chipset is soldered directly to the motherboard.
(Via a BGA surface mount)
It is either an ATI Mobility Radeon X300 with 64MB of video memory, or an ATI Mobility Radeon X600 with 128MegaByte of video memory.http://h18000.www1.hp.com/products/quickspecs/12114_na/12114_na.HTML
As such, replacing the graphics chipset is more feasibly done, by replacing the motherboard.
A) What makes you think the graphics chipset is bad?
You plugged in an external VGA monitor, (Laptop OFF, monitor OFF), and the graphics are distorted on the external VGA monitor?
[ Turn the external VGA monitor on. IF a CRT type, (Looks like a small TV), allow it to warm up.
Turn the laptop on.
If graphics do not show up on the external VGA monitor, press, and hold down on the Fn key, and simultaneously tap on the F4 key.
You may have to perform this procedure more than once, as there are several display options ]
B) Video Cable:
Loose connections of the Video Cable TO the motherboard, and/or TO the back of the LCD screen, can cause a bad display.
B1) A damaged Video Cable can also cause a bad display.
Just from the usual opening, and closing of the laptop, may damage the Video Cable. It runs across the motherboard, and under the left Hinge Cover.
Laptop partially disassembled, look at the Video Cable on the motherboard side, and see if there are obvious signs of damage to the Video Cable's sheath.
There may be damage to the tiny wires inside the cable, also.
The best method is to remove the Video Cable, and with an economical multimeter perform a continuity test of all the wires inside the cable.
(Multimeter set to Ohms)
Chip and Chipset are slang terms for I.C.
The I.C. for graphics is a graphics chipset, or G.P.U.,http://en.wikipedia.org/wiki/GPU
The GPU for your laptop is mounted to the motherboard with a BGA surface mount,http://en.wikipedia.org/wiki/Ball_grid_array
To explain the 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, the chipset has Solder Balls on the bottom.
The motherboard has matching Copper Pads. (Usually coated with a thin gold plating)
The chipset is set into place over the motherboard, with the Solder Balls lining up with the matching Copper Pads.
Heat is then applied at a specific temperature, and length of time.
The Solder Balls melt which solders the chipset to the Copper Pads.
(Which in turn solders the chipset to the motherboard)
The Processor and graphics chipset are the two hardware components, that give of the most heat.
IF, the laptop is kept dirty inside on a constant basis, the graphics chipset will overheat.
Constant overheating may partially melt those solder connections (Joints), and cause a bad contact of the graphics chipset to the motherboard.
IF the graphics chipset is bad, you will need to find another one.
(Ummm, good luck)
Then a BGA Rework machine should be used to remove the bad graphics chipset, and solder in a new one.
OR, if the mounting of the graphics chipset is bad, (Solder connections), a BGA Rework Machine can resolder the connections.
This is why I state it is more economical, and feasible, to just replace the motherboard.
[ Laptops that DO indeed have a dedicated removable graphics card, base it off of the MXM technology,http://en.wikipedia.org/wiki/MXM
Laptop manufacturers use the term 'Graphics Card' too loosely.
They state it, to make the consumer believe the laptop has a removable graphics card, when it doesn't.
Better for sales, and also helps the consumer understand about their laptop's graphics devices; but is used wrong.
They are stating Graphics Card, when it is really just a graphics chipset, soldered to the motherboard.
Kind of like people referring to a computer as a CPU.
CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
