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.

CHANGING THE VIDEO CARD ON HP PAVILION TX1000

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.

http://en.wikipedia.org/wiki/Socket_S1

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

http://www.ebay.com/itm/nVIDIA-NF-G6150-N-A2-BGA-North-Bridge-Chipset-NEW-/220724258873

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)

More information on a BGA surface mounted device, using a BGA Rework Station,

http://www.ersa.com/art-ir-pl-650-346-1472.html

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

Also another method used to remove, or reflow a chipset.

(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)

MHO?
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.

Cant find a workable coprocessor, ethernet controller and sm bus controller driver for my hp dv6000 laptop on hp's site.


do you use Vista 64 OS, if yes, then try this.

coprocessor + sm bus controller + ethernet = chipset driver

Nvidia chipset driver

ftp://ftp.hp.com/pub/softpaq/sp36001-36500/sp36079.exe


they all r included in chipset driver, if your NB has AMD processor

plz confirm if it works

The laptop is a dv6700 HP Pavillion. What steps should I take to solve this issue.


About it being an HP Pavilion dv6700 laptop?
Ehhh, giveittome. I will use it.

Looks like I'm going to have to guess since the 'Issue' wasn't stated.

The main problem with the Pavilion dv6700, which is part of the Pavilion dv6000 series of Notebook PC's, is that all the indicator lights come up, but there are no graphics being shown on the LCD screen.
The screen is black.

This is due to a graphics chipset problem, caused by a poor cooling design of HP designers.

The graphics chipset (GPU. Graphics Processing Unit), is mounted to the motherboard in a BGA surface mount.

Instead of pins coming off of the bottom of the chipset, as on the older Processors, there are Solder Balls.

The motherboard has tiny copper pads that line up to the solder balls.
The graphics chipset is set into place, then heat is used to melt the solder balls, and attach the graphics chipset to the motherboard.

Due to the poor cooling design, the graphics chipset overheats, and the solder connections are partially melted.
The graphics chip now has a poor contact to the motherboard.


This video shows you what's going on, and how to solve the problem,

Hp dc 7700 SFF, board is 965 chipset & i want 64-BIT processor


Yes, it the Intel 965 Express chipset will support processors that are based on the 64-bit technology.

This is to include the;
1) Intel G965 Expresschipset
2) Intel P965 Express chipset
3) Intel Q965 express chipset

Supporting Data;

1) Intel Support, and the main support page for the Intel 965 Express series of chipsets,

http://www.intel.com/support/chipsets/sb/CS-022768.htm

In the top list given, you can click on -
Associated Intel Processors,
to see if the processor you have is compatible.

2) This is a List of Intel Chipsets, on Wikipedia,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_Chipsets

I have linked the page so that it comes up directly on the Core 2 chipsets.

Here looking down the left column, you will see the G965, P965, and Q965 Express chipset's listed.

You can scroll across to the right for each chipset listed, and see what processor types the chipset supports.

There isn't an Intel Core 2 processor made, that isn't a 64-bit processor.

I cant play a movie full screen on my hp laptop.. it goes black and grey everytime. what should i do =[


I think you need to update the graphics driver. It might be downloadable from the laptop or chipset manufacturer's support website. For example, if your chipset is made by intel, please go to intel.com/support/chipsets then select the chipset family. Choose the specific chipset then click on "download" under graphics. After this, please select the operating system...hope this helps.Please let me know. Thank you.
