Hmmhh, I am getting skeptic, if he already idles at 24W and the battery still has only 55Whrs then one just cannot get more than 2hrs 17minutes. So it would be interesting to see what cat /proc/acpi/battery/BAT0/info on the new mbp's says. > Soeren, is your C1D similar or is this really an nvidia thing? Have > you tried Beryl/Compiz?

As I said I can down to ~16-17W on idle so 2.5hrs sound realistic when you don't do powerconsuming things. > My hope is still to one day use this machine with Linux and Compiz and > have it at least be quiet and not too hot when connected to power.

Anyway regarding heat I am (in summer) setting min fan speeds to 2500 or 3500 ... else it is too hot on the lap.
