Hi,
To start off, I want to point out that my Dell Latitude has Intel SpeedStep (800Mhz/1200Mhz).
When my dell latitude is plugged in, KPowerSave automatically chooses performance profile.
Problem: The performance profile is actually the exact opposite of performance profile. When my laptop is running on battery and I trigger an application, the cpu works at its highest frequency when needed (on demand). However when plugged in, the cpu stays at its lowest frequency speed (800 Mhz) even though its running in performance profile despite the fact of using heavy application, the cpu does not speed up and I can notice it as well. Can anyone help me make my cpu run at highest frequency (1200Mhz) when plugged in?

in /etc/powersave you'll find the config files for the powersave daemon.
As root, edit file 'commom' and make sure to set the following:
AC_SCHEME="performance"
BATTERY_SCHEME="powersave"
Then, edit the files 'scheme_powersave' and 'scheme_performance'. Each file has a line that says
CPUFREQUENCY="-VALUE-"
The -VALUE- can be dynamic, powersave or performance. Enter your preferred value and save the file (as root).
When finished, do /etc/init.d/powersaved restart in a console, and check if it works OK.
You can click the battery icon to check the frequency of the CPU
