I've looked through the 26 pages/photos of how to disassemble the 6700. A lot of work just to look inside. I've removed the goodies, (the HD just wanted pulling hard.) and powered up each time in the hope one item was crow-baring the power. Just the same.
How to take apart HP Pavilion dv6000 laptop >> Inside my laptop
Tomorrow, when blood is undiluted, I'll sneak a look inside. No chance of HP doing anything by the sound of it. Nvidia have brought their compensation period to a close - as stated above, in 2011.
Now, here's a clever young chap. He may well have hit the nail on the head.

I had the same problem for almost 3 years. I was just about giving up on this computer when I decided to give it a shot at tearing this thing completely apart. I followed a good procedure on this web site

It was about 95% accurate for dv6700. I removed the fan/heatsink assembly and cleaned it. The laptop got quite a bit cooler and the time to total-meltdown went from about 1 hour to more than 3 hours. But it still eventually "froze" (how ironic). The center of the keyboard and the touchpad still got extremely hot.
Unsatisfied, I attempted a second repair. This time I found the real culprit. Due to either a design flaw or manufacturing mistake, somehow, the GPU dose not touch the fan/heatsink contact plate. Instead, there is a piece of flexible plastic spacer in place. No wonder the center of the unit gets so hot. Luckily, the solution is simple. I used a dime, which happens to be about the same thickness, to replace the spacer. Of course, you need to use thermal grease to improve contact. Now my dv6700 runs very cool. The center feels warm but not hot. If you put your hand at the fan exhaust it actually feels cool! It's amazing what a dime can do in this economy.
I'm really puzzled that HP could not find the cause and therefore a solution for such a widespread problem. I think HP truly owes all dv6700 customers a big refund.
