Greetings Barb and list-- Have you checked whether certain "system events" can turn on your computer in your BIOS/CMOS Setup area? Press whatever key allows you into setup when you boot your computer, and check the various menus for "wake up" events. Some are 'wake on lan' or 'wake on incoming call' (for a modem), and there are others. See that they are disabled if you do not want any automatic wake-up calls for your computer. HTH, Paul A.
