when i close the lid on my new Gateway with Vista, it doesnt go to sleep, which is what i have it set for. Then when i reopen the lid, theres a flash, the screen goes black and i get an error written across the screen that the computer "...did not shut down correctly..." and then gives me the option to restart in Safemode, Safemode with networking, or nornal start up. ive checked and rechecked the sleep setting in the powersaving utility and everything seems normal. anyone know what the problem might be?
