Why should I use power management? |
|---|
|
Nationwide, PCs and
monitors in commercial and industrial settings use 32 billion kWh of electricity
each year -- over 1.5% of all electricity consumed by the commercial sector.
More than half of this energy could be saved through the power management |
|
Does power management harm my computer or monitor? |
|
Power management does
not have a negative effect on the useful life of computers and monitors. On the
contrary, 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 monitors |

Do screensavers save energy |
|
Screen savers were
originally developed to prevent the permanent etching of a pattern on older
monochrome monitors caused by a single image projected over a long period of
time. Screen savers would prevent this by either blanking out the screen
entirely or by displaying a constantly moving image. Modern display screens do
not suffer so much from this problem so screen savers are mostly an adornment.
Screen savers were never intended to save energy. However, certain darker screen
savers can save energy compared to brighter screen savers and include: 3D Flower
Box, Flying Through Space, 3D Flying Objects, Flying Windows, 3D Text, Mystify
Your Mind, Curves and Colors, Scrolling Marquee and Blank Screen |
