I'm using a DV6000 series HP laptop,specs as below:

Code Duo T2250 1.73ghz
geforce go7400 128mb
3gb ram
windows 7
120gb hdd (3gb free after installation)

game works fine, and even defaults to medium settings

i had to lower all to LOW and use the lowest resolution,and so far so good.
the cinematics lag like crazy(during the final sequence,the credits actually appeared DURING the video sequence!it's that laggy but the audio during those sequences play just fine)

game wise it's good enough. as far as i can tell only in really explosive battles does it hog down.

reading about the overheating issues got me scared,but so far i'm yet to overheat the laptop,despite playing more than 5 hours sometimes.

just for shits and giggles, i installed the game on my secondary laptop:
c2d t5270 1.40ghz
3gb ram
integrated gc
windows vista basic

the game installs just fine
movies run great
but the game lags like crazy.

and im talking about the first level of the campaign
