Is there anything that I can install that will stop my MacBook from going to sleep when the lid is closed? I have tried Insomniax but it leaves the screen on, and I'd rather have it turned off. The only way I know of doing this is closing the MacBook and then using my RowMote Pro app on my iPhone to sleep the display. Insomniax has a "Sleep Display" option but it doesn't work on Snow Leopard. All I want to do is close my MacBook lid and disable sleep mode, and turn the display off.
