Using the BIOS Setup Utility 3-23
Windows 98 SE/Windows Me and Intel SpeedStep Technology
Use the Intel SpeedStep technology (available in systems with Intel Pentium III
processors) to optimize processing speed and conserve battery life.
Enable Intel SpeedStep technology through the BIOS Setup utility. The available
settings are Disabled, Battery Operation, and Automatic.
!
Use Automatic for the system to perform in full power mode when the system is
running under AC power.
!
Use Battery Operation for the system to use power conservatively whether the
system is running on AC power or battery power.
!
Use Disabled to turn off Intel SpeedStep technology.
If Intel SpeedStep technology is enabled in your system, an icon appears on your
taskbar allowing you to adjust processing properties. However, the default settings are
recommended for optimal performance and battery conservation.
For information about accessing the BIOS Setup utility refer to “How to Use Setup”
and “Advanced Menu” earlier in this chapter.
Windows Power Management States
ACPI uses different levels or states of power management. These power management
states occur automatically, based on the system’s default settings, or manually, when
invoked. Settings are configurable to occur while on battery power or AC power.
The ACPI power management states in the Windows 2000, Windows 98 SE, and
Windows Me environments include:
!
LCD timeout — manages power at the lowest level by shutting down the LCD.
!
Standby — also known as Save-to-RAM (STR), Standby manages power by saving
your current working environment to memory and shutting down most system
devices. Conserves more power than an LCD timeout.
!
Hibernate — also known as save-to-disk or save-to-file (STF), Hibernate manages
power by saving the current working environment to an area on your hard disk, then
powering off your system. Conserves the most battery power.
