I guess it's possible the fan's bearings are worn/clogged and it only gets enough power to spin up when plugged in. If you haven't taken it apart to clean it within the last year it's worth a shot.

Did you check what power mode you are in? If you right click on the battery in the taskbar you get to the power options. If you have it set to save power rather then performance it will do things to conserve power like your screen brightness will be decreased. Plus one of the things is it will generate less power and less heat will be generated.
