Using the Screen Saver
When the screen saver is started, it will initially display a bouncing logo on a black background. To
enable additional levels of power savings, select them from the Screen Saver Mode section of the
Setup dialog box.
Screen Saver Mode
The Screen Saver Mode section has four check boxes in it. They are
•
ReducedOn
•
StandBy
•
Suspend
•
Off
The screen saver detects the type of graphics controller that is being used and the types of power
savings that it is capable of.
If the text immediately to the right of any of the check boxes is gray, that option is not available. If a
power saving mode is available, then the text immediately to the right of the check box is black. If the
box is selected with the mouse or the keyboard, the rest of the fields on the line will also turn black. If
the check box is deselected, the other fields will turn gray.
The minutes field for each line can be changed only if the check box for that line is selected. The
amount of time can be set for any number between 1 and 60. The number can either be typed
directly, or by clicking on the up or down arrow next to the number. Holding the mouse button down
on the arrow will quickly increase or decrease the minutes field.
The number of minutes that is specified for each level is the number of minutes after the previous
mode has been enabled. It is not the total time before entering that mode.
Screen Saver Animation Speed
The scroll bar controls how fast the animation moves. The checkbox controls whether or not a
bouncing sound will be played whenever the logo hits an edge of the screen.
Password Options
If the password checkbox is enabled, then the screen saver will prompt the user for a password
before it quits. The password is the same one that is used for other Windows 3.x screen savers.
The Energy Star Program
Energy Star is a program created by the US Environmental Protection Agency (EPA) to promote
energy efficiency. The goal of this program is to lower electricity usage by making computers and
related hardware more energy efficient.
Computers currently use an estimated 5% of commercial electricity consumption. If no actions are
taken, this could rise to 10% by the year 2000. Ironically, much of this electricity is wasted. Research
shows that the vast majority of time personal computers are on, they are not actively in use.
Additionally 30% - 40% are left running at night and on weekends.
Electricity generation accounts for 35% of all US emissions of carbon dioxide - the most prevalent
greenhouse gas. It also accounts for 75% and 38% of all US emissions of sulfur dioxide and nitrogen
oxides respectively - the two pollutants most responsible for acid rain.
