Setting
Up A Computer To Minimise Energy Use
|
| 1. |
Set the monitor to turn off after
ten minutes of inactivity and the screen saver to start after
15 minutes. |
The screen saver never appears but
it does mean that when the system resumes a password screen
can be presented which is good security. Running a screen saver
can also stop the processor from switching to low power mode. |
| 2. |
Set the hard disk(s) to power off after ten
minutes of inactivity. |
The short wait for them to power up when needed
is a small price to pay. |
| 3. |
Set the system to switch to standby after 15
minutes. |
|
| 3. |
Set the system to
hibernate after 20 minutes. |
|
Note: Older computers and some operating systems
may not support all of the functions.

The figures above can be reduced further to save
more energy but at the expense of a short wait while a computer
comes out of standby or hibernate.
To achieve even greater control and save more energy
install a shutdown utility such as AllOff or AllOff Lite which
will shutdown or hibernate the computer due solely to lack of user
input. It is quite normal for computers to carry out house keeping
tasks such as disk de fragmenting when idle which can stop the
computer going into standby for many hours. If you have more than two computers networked together a utility such as LANOff may help control energy use. The computer utilities referred to here are all from JSutils a site that specialises in energy saving and calculation software.
