Unchecking the "Vari Bright" option in the ATI Catalyst Control Center resolved the issue for me as well. It seems this option dims the brightness of the display when unplugged; however, I believe Windows also does this (or, at least it does on my Dell XPS 16). Perhaps two programs attempting to essentially do the same thing are the cause of the atibtmon issue?
