    That would be on page 31 of the schematic PDF. What's up? You found someone to figure things out?

    Well, it's likely that the problem from the very beginning is the LVDS cable.

    When you know who reversed or inverted (I can't recall which) the LVDS it enabled the Quadro to a degree, but with the wrong bit rate… hence the lackluster display. The most likely culprit, according to two very tech savvy people I have spoken with, is that a pair of wires or strands within the LVDS cable reversed send and receive (if that's the right term), which would drop the bit rate.

    There's a reason why the industry moved away from LVDS.

    There's also a reason why rational laptop manufacturers don't bury the CMOS battery in the guts of the machine, but that's a different subject altogether. Changing the CMOS in my HP 8740W takes 5 minutes, which suggests that different teams at HP work on different product lines, and that some of them must be into heavy drinking.
