Your post is pretty old but I thought I'd add a reply. I'm having the same problem with my HP notebook. The screens dims when I plug it in to AC power and brightens on battery. However, I haven't noticed the drop in processor speed when it's plugged in to AC power.
Perhaps you should try Dell's power management software called Dell Quickset, I use it on my Latitude D600,
