Hi~ I had a question regarding my computer. I know there are many programs that are alarm clocks for Ubuntu, and I was wondering...do I have to leave my computer running all night in order for them to work? Because my dad gets on me about how much my computer is on already...and the alarm clock I bought at the store doesn't seem to work very well. But I did get a plugin for Songbird, which raises another question: would I have to keep songbird open all night to get the alarm function to work?

If I can't turn my computer completely off, would I be able to use some sort of 'sleep' setting that saves energy? That might be my best bet...

PS, I run Ubuntu 9.04.

Thanks for any and all help!
