Power Management Modes (Cont’)
Full Power Mode & Maximum Performance
The Notebook PC operates in Full Power mode when the power management function is disabled by configuring the
BIOS Setup. When the Notebook PC is operating in Full Power Mode, the Power LED remains ON. If you are con-
scious of both system performance and power consumption, select “Maximum Performance” instead of disabling all
power management features.
APM and ACPI
Advanced Power Management (APM) was developed by Intel and Microsoft for DOS/Windows 3.1/95/98 which
controls only the main system power functions. Advanced Configuration and Power Management (ACPI) on the hand
was developed by Intel, Microsoft, and Toshiba especially for Windows 98 to control power management and Plug and
Play features on system devices designed on the Wired for Management (WfM) 2.0 baseline. Because not all external
peripherals are ACPI compliant, only APM is installed by default (using the command “setup.exe”). Since this Note-
book PC is both ACPI and WfM 2.0 compliant, you can install Windows 98 using the command “setup /p j”. ACPI
cannot be installed after Windows 98 is installed. Reinstallation with “setup /p j” is required on existing Windows 98
systems.
Suspend Mode
In Suspend-to-RAM (STR) and Suspend-to-Disk (STD), the CPU clock is stopped and most of the Notebook PC
devices are put in their lowest active state. The suspend mode is the lowest power state of the Notebook PC. The
Notebook PC enters Suspend when the system remains idle for a specified amount of time. The timeout setting of both
Hard Disk and Video can be set by the BIOS Setup. To resume system operation, press any key. The Power LED will
blink when the Notebook PC is in either one of the power saving modes.
Standby Mode
In addition to reducing the CPU clock, this mode puts devices including the LCD backlight in their lower active state.
The Notebook PC enters Standby mode when the system remains idle for a specified amount of time. The timeout can
be set through the BIOS Setup. To resume system operation, press any key on the keyboard, touchpad, or external mouse
(or moving the mouse).
