Speedstep effects?!? WAS: [SOLVED] Re: FC2 won't boot on battery!!

[Dave Oxley]

I have done a bit of testing with Speedstep turned off and on (both on 
mains supply). The performance of the laptop appears to be significantly 
reduced with Speedstep turned off. The application I work on compiles in 
11 seconds with Speedstep turned on and 30 seconds with it turned off! 
 From the comments provided I wasn't really expecting this. Any ideas?

Dave.
