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



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?

Yes, disabling Speedstep will shorten your battery life by 40%-50%.

Dave,

Check the BIOS settings on Power Management.  The Inspiron 8600 has
Intel Speedstep Technology enabled by default.  That means that on
battery power the processor runs at half speed.  Try setting the bios to
leave the processor at full speed on battery and see how that goes.

Best,

Steve

I have FC2 (with all updates) installed on an Inspiron 8600. The machine works fine when plugged into the mains but will not boot when running on betteries. It gets to 'Setting up local disks' and hangs. Does anyone know how I can solve this?

Cheers.
Dave.
