Here's the latest in our new series on OS tips from power users: a seemingly trivial task. You have a computer, most likely a laptop, that you wish to keep suspended while you're not working. For example, let's say overnight. At the same time, you wish to run a handful of maintenance tasks, like backups and cleanup, which you don't normally do during the day. So you need a mechanism that will send your machine to sleep, wake it up when necessary, run cron jobs, then send it back to sleep again.
