Looking For: 386 laptop, IBM or not.
How do I find him on the forum, as I can't seem to find search anywhere?
I did a web search with his name, and the forum name, and found out that he lives in Frankfurt!
I need to find a modder here in the US. It's conceivable that the gentleman might be able to troubleshoot from the schemata, but ideally I need to find someone who could be paid to do the actual mod.

I admire what people have done modding their Thinkpads, and have confidence in our long term members. This is a real community, managed by Captain Bill.
I was hoping to find someone on this forum because of what's been done here.
Some years years ago HP produced a unique laptop, the HP HDX Pavilion 9000 series, known as the Dragon. It has a 20.1 inch display that is fully articulated, amazing speakers, and a great keyboard. The problem was the Nvidia 8800M GTS card which is somewhat under-powered, and has a tendency to fail after three years or so, usually due to heat. It should have been recalled along with the defective 8400-8600 series, as the defect is the same.
After many unsuccessful attempts to upgrade the MXM card, a very capable technician figured out that the LVDS cables were inverted relative to the typical laptop layout. As a result he installed an Nvidia Quadro 3700M into the Dragon, and it works. It processes video as it should, but there is one anomaly… The WUXGA screen, which is an 8-bit screen, appears dimmer, or less intense than it should, giving the screen a dull appearance, and it's been established that the 3700M is only putting out 6 Bits to the screen, which would give it the symptoms described.
I was unsuccessful in reaching laptop guru/modder Leo Kim from Thinkpad.kr in South Korea who knows how to change the bit output on this card. Moreover, this may not be the reason that the display is dimmer with this card, though it is probable.
Recently I found out from a technician at another company that the LVDS cable may still be the culprit, with one or more pairs of wires in the LVDS reversed, reversing signal and return. This would definitely drop the Bit output. As a scientist friend once told me, the first step in troubleshooting is cabling. It's been the culprit so far.
Replacing the GPU is the immediate goal. There is another idea that is right up the alley of those who make Frankenpads.
