Does anyone know where to get the schematic for the dv6550us motherboard?


The closest I come to an HP Pavilion dv6550us, on HP Support, or on the internet is;

Pavilion dv6550tx
Next inline is Pavilion dv6560us,
then Pavilion dv6450us

Not available to the public.

Do have a Block Diagram,

Both use the Fairchild Semiconductor Industries - FDS6679 - Power MOSFET, and Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET, in the DC - DC circuit; as far as I know.

Both are Obsolete, but there are cross match examples out there.
(FDS6679AZ for FDS6679, for one)

Indicates HP Pavilion dv9000 series, and AMD; but also matches up to the Pavilion dv6500 series,

Asking for a Schematic, do I assume you are attempting
Board Level Component replacement?

What SMD/SMT IC component are you trying to replace?
(Surface Mount Device/Surface Mount Technology. Integrated Circuit)

Motherboard chipset info, and processor socket info, for processor upgrade.
Same thing for Ram Memory upgrade.
It does use DDR2 Sdram (SO-DIMM), and at 667MegaHertz, to my knowledge.

What usually goes bad on the HP Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's?

The cooling for the graphics chipset is inadequate, therefore the graphics chipset overheats, and partially melts the Solder Joints in the BGA surface mount.

Resulting in no graphics.

Power MOSFET's in DC - DC circuit go bad.

NVIDIA chip not working


I'm interested in buying non-working HP DV2000, DV6000 and DV9000 motherboards.

Go to google and look up precisiondivision . com

I prefer to buy them in bulk, so if you're a shop and have a ton of these, don't toss them - I'll pay you for them!
