Scheduled powered events

If you want to find out when your mac is scheduled to wake up or power on because it's missing important events, such as recording television shows, launch Terminal.  Verify using this utility that these Events are getting set properly. There is a command-line tool that can be used to view the existing Events within your Mac's Power manager. To use this tool, launch the "Terminal" utility, located in /Applications/Utilities/Terminal, then enter the following command (you can copy/paste the line below) and press return:

pmset -g sched

The resulting output should look something like this:

Scheduled power events:
[0] wakeorpoweron at 08/05/09 19:56:00 by com.elgato.eyetv

If there are no Events listed here, then there may be a problem with the "Wakein" component, a small script that EyeTV uses to create Events. If there are other Events listed here, these can conflict with some older versions of EyeTV, which cause EyeTV not to place its own Events.

Note: Before you check out this component, you may want to restart your computer and retype pmset -g sched into Terminal. The output may now be there.
