Should be able to find the pinout of different boards in pdf format through the mfg.
Use CPU-Z to identify the boards. Google the boards individually. At the very least it shouldn't be too hard to find user manuals, but data sheets are usually readily accessible too.
Yea been doing that for almost 3 weeks now and still haven't found the right schematics. Found a lot of schematics close but no cigar. Basically it's a schematic for the LCD Flex/Flat ribbon cable - 40 pin connector at the motherboard to 30 pin connector at the monitor to 7 pin connector at the inverter for the LCD monitor in a Compaq Presario C700. The wire got frayed from the opening and closing of the lid. Obviously someone at HP engineering didn't carry the one somewhere because the wire gets pulled and stretched every time it gets opened. And then instead of making some kind of propriety cut out or anything they stuffed it between the hinge and the body. Now instead of buying a new one for a laptop this old, It would be easier to just repair the wires. But in my hectic days I forgot to mark down what wires went where. Even tho they basically match up as far as the colors go, the monitor connector and the inverter each have some of the same colored wires and I don't want to just match them all up and end up frying either the monitor or the inverter or whatever. I am currently working on a table with the wires and what I have figured out so far as far as where I believe the wires go but I'd rather have someone that has more experience than me in electrical repairs to let me know what they think.
I do have extensive experience with electrical repair, but not laptop electrical repair. I do have computer and laptop repair experience but I normally do not do rewiring repairs just replacing hardware. It's just taking a while.
