Power Management

The use of power management can reduce energy consumption and cooling costs, reduce noise, and prolong the battery life of laptop computers. When your computer consumes less power, you reduce your impact on the environment and you also save the university money.

ITSD recommends that you set your monitor to turn off and your hard drive to spin down after a period of non-use. We recommend the following power management settings:

Personal Computer on Campus
Turn off Monitor - after 15 minutes
Turn off Hard Disks - after 30 minutes
Shut down - every night

Classrooms
Turn off Monitor - after 2 hours
Turn off Hard Disks - after 2 hours
Shut down - every night

Computer Labs
Turn off Monitor - after 15 minutes
Turn off Hard Disks - after 30 minutes
Shut down - every night
Or evaluated individually depending on type of lab.

Home
Turn off when not in use.

MYTH or FACT

Myth: Screen savers save your screen.
Fact: Screen savers were originally developed to
prevent the permanent etching of a pattern
on older monochrome monitors. The same
protection occurs when you place the monitor
in a low power “sleep” mode. Avoiding the
use of screen savers on LCD and CRT displays
can reduce power usage while away from your
computer by 30-75 watts.

Myth: Computers have a shorter life when you
turn them on and off frequently.
Fact: Hard disks in PCs older than 10 years did not
automatically park their heads when shut
off, leading to disk damage from frequent
on/off power cycling. Newer PCs are designed
to handle over 40,000 on/off cycles, a
number unlikely to be reached during a
computer’s typical four-to-six-year life span.

Myth: Turning your computer off uses more
energy than leaving it on.
Fact: The surge of power when a computer is turned
off lasts a few seconds and is insignificant
compared to the sustained energy used in
keeping it on during periods of inactivity.
