    Yes, electrons moving around in a fast manner tends to produce a temperature raise.

    Is there some kind of issue with using the machine that you're specifically trying to fix?

    When you have it connected to the wall, the power plan changes and lets the machine work more to its abilities. When it is not connected to the wall, it changes certain things to not work as fast as possible (or things like dimming screen) so that power can be saved and battery life is extended so it doesn't need a recharge so soon.

    What you're describing is normal operations.

    Like MasterChief says it may run differently when plugged in versus unplugged. My laptop will switch from the dedicated graphics card to the onboard video chip in my processor. The CPU will run slower too at a lower clock speed to save battery. My display backlight will dim when on battery only. If you were running on battery and then plugged the power pack back in your laptop also has to recharge the battery on top of whatever else its doing. That may generate even more heat.
