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

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.

Hmmm, had I have clicked on your user name, and looked at your account, I could have seen previous questions asked, lol!http://www.fixya.com/support/t17549112-h... It's either the FDS6679, or the AO4407, or both. Also look at the second photo down on the Mayohardware link. Has the AO4407 circled in Yellow. Look at the small rectangular object to the Immediate Right, with the dark wide band in the middle of it. That is an MLCC. Multi-Layer Ceramic Capacitor. It is SMD/SMT. There is one above it, one above that one at the Top; one to the right of the Top one, and one to the right of it. (Placed vertically)........There are also 4 smaller examples to the Bottom/Left corner, of the AO4407. Here is an example; Rated at 4.7uF (Microfarad), and 16 Volts,http://jp.mouser.com/ProductDetail/TDK/C...
Thanks for the comments Joe. At this point I have not yet figured out which component(s) is (are) bad. The only thing I know is that the power from the AC adapter reaches the motherboard but not to the pins of the battery connector and beyond. I can measure the voltage to the connector point on the motherboard and cannot go beyond. I'm suspicious to TPC8111 but am not sure. That's why I'm looking for the schematic at least for this section of the motherboard to go forward.
Field Effect Transistor / Silicon / P Channel MOS type / Lithium Ion Battery Applications ->http://datasheetcatalog.com/datasheets_p... Plus click on the blue - TPC8111 datasheet - in; Download TPC8111 datasheet from TOSHIBA. In otherwords a Power MOSFET.......-> Notebook PC Applications / Lithium Ion Battery Applications..........What lead you; is leading you, to this chipset? Looked burned?........Just curious.....
No it does not look burned ... but, both the input and output voltages (source and drain) are tied to 0V which is not right,unless, the feed to it is broken. This is where I am stuck at and need the schematic for .
Not indicating I know anything....Just using logic, (Or what I believe to be; Ha!), and asking; 1) I'm guessing you are referring to a schematic of the motherboard, and not of the TPC8111.....2) I, in just wondering......if you know which pin is the feed, and it's not receiving voltage, then what component is next in line for it? Going up that circuit trace, from that pin; what component, and lead of component, is it connected to? I would think an MLCC. Before it an SMD fuse..........HOWEVER......it looks by statements made, that you have board level component skills, while I do not.........That's why I'm just asking........
1) You are right ... I do have the schematic for TPC8111 and am looking for the motherboard schematic. 2) I'm not sure which pin is the feed and which one the output. But I know that the D and S should not be at the same potential, especially 0V. Also, it is not easy to trace the signals on the motherboard, at least with the magnifying glass that I have. ... it is my first time I'm dealing with a motherboard designed by someone else ... I do my own boards; not as complex as the motherboards; and since I have the schematics it is easy for me to troubleshoot them. In here, had I had he schematic it would be much easier to handle ... Thanks for your comments anyway. I still think that I need to find the schematic for the motherboard to be able to have it fixed ...
