I have set in my Energy Saver Prefs to have my display turn off in two minutes and have the computer never turn off while plugged in. I am running MBP with NVidia GeForce 9600M (I have the option to go to "Better Battery Life" and switch it to 9400 if I so choose.) Is anyone else experiencing this problem? Can somebody try to replicate it and tell me if it's just me? This happened when I installed 10.6.3, .2 was fine. Thanks a bunch!
