The following, should be turned off at the end of the day and over weekends and during vacations:
Please note that many modern devices continue to draw a small amount of power even when turned off. To eliminate all power consumption associated with your computer and attached devices, switch off the power strip those devices are plugged into.
In addition, we recommend the following power-saving settings for your computer. Computers and monitors that meet Energy Star standards set by the U.S. government support these settings, which cause the devices to consume less energy after a period of inactivity. All monitors and computers purchased by W&L comply with these standards. Laptop users may wish to choose shorter time periods, especially when running on battery, in order to extend the time between charges.
Select the Start Menu -> Control Panel -> Power Options. This should bring up a Power Options Properties dialog box that allows you to set the time to elapse until separate components power down.

Select the Apple Menu -> System Preferences -> Energy Saver. This will bring up a dialog box for setting sleep times for the entire system, the monitor, and the hard disk.
