  Power Cycling
A modest amount of turning equipment on and off will not harm the computer. The life of a monitor is related to the amount of time it is in use, not the number of start and stop cycles. Modern hard disks are also not affected by frequent shut downs. The equipment may actually last longer because mechanical wear and heat stress are reduced. When equipment powers down, it generates less heat, collects less dust, and reduces mechanical stress, promoting a longer and more reliable life for the computer and monitor.
  Energy Tips
If you are leaving your office for several hours, please shut down your computer. It only takes a few minutes to start up again. If you are leaving your office for more than an hour and cannot adjust to shutting down your computer, please turn off the monitor by pressing its power button.

Never leave your computer on overnight! It is not good for the environment, the computer, or the server you have probably left yourself logged into.

If you are sitting in your office when the monitor goes to sleep, please leave it sleeping if you are not actively using your computer. It does not take long for the screen to come back to life when you touch the mouse or a key on the keyboard.

If no one in your area will be using a printer for more than a couple of hours, and always at the end of the day, turn off the printer. Hewlett-Packard, the manufacturer of almost all Northern printers, recommends printers be turned off when not used for more than a few hours. Turning off printers not only saves energy, but also increases the life of the printer by reducing wear on moving parts.
