Hey everyone, so I have a Powerbook G4 and I am using a Targus Mini Kaleidoscope optical mouse that has colorful LED lights that change colors. My problem is that my mac won't go to sleep. Is it possible that the lights in the mouse are causing my system to think that it is still being used, thus not allowing my laptop to go into sleep mode? Basically, I'm trying to figure out why my mac isn't going to sleep with this mouse plugged in. Any help would be greatly appreciated. Thanks.
