I'm new to MAC OS X this iBookG4 is my first ever MAC product and wanted to know if there is a way to set some settings so that when I close the lid it won't go to sleep. I would like for it to stay on because I have hooked up my 42" Plasma and would like to close the lid and not have it go to sleep. Also would like not have it go to sleep when I'm just using it also and close the lid.
