Sorry, my mistake. The comment was on another forum somewhere and I can't seem to find it. It was not particularly revelationary as I recall. One user reported the random power downs and another responded that it was likely overheating.
This got me thinking about the new power management features in Windows 7. I understand that Windows 7 does some stuff behind the scenes to optimise power usage, much more than previous Windows versions and I thought that perhaps this is somehow incompatible with the older Dell laptops.
It might be worth looking into disabling the new power features and seeing if the systems run cooler.
It's definitely overheat! When my 700m with windows 7 7127 power off, I was usually copying several Gigs of files from one place to the other place & watching rmvb or divx & using firefox... The vent on left hand side was extremely hot. What surprise me is that it never happened in XP...

A search of Google for "windows 7 overheat" reveals a number of similar reports, overheating in Win7 but not in XP.
No obvious solutions found...yet.
Try installling Dell Inspiron Inspiron/Latitude/Precision fan control (Not sure if it will work with win7) And keep an eye on the temp. While you are at it see if the fans are set to low speeds eventhough they shouldnt be. If so set them on high. You can also underclock your pc if you wanted to.
I have an insiron 1405 (old as the hills) and it ran hot enough to even cause some instability. it wasn't just on win 7, but on vista as well. Besides the obvious things I did download core temp to monitor the temp, and 18kfanto see if I could get it to run cooler (which it does). what power plan are you using i win 7? high perf, balanced or battery?

I think I may be back on track. I installed "Notebook Hardware Control" (at Notebook Hardware Control (NHC) - Homepage, Downloads, Help, Docu, FAQ, News - www.pbus-167.com) and decreased the CPU voltage so that my system runs about 10 degrees cooler (in celsius). So far today I have not had a crash and also just completed a burn-in test using Sandra.
Fingers crossed that this is a work around.
Please post here if anyone has success with this method.
So, both 3722 and 4656 driver worked for my 700m now, thanks to Arathranar with his solution to the 0x7E BSOD... Great!
