Note: DC-AC inverter is used to generate very high AC voltage, to 
support to LCD CCFT backlight user, and it is also responsible for 
the control of LCD brightness. Avoid touching the DC-AC inverter 
area while the system unit is turned on. 
Note: There is an EEPROM in the inverter, which stores its supported 
LCD type and ID code.  If you replace a new inverter or replace 
the LCD with one of a different brand, use Inverter ID utility to 
update the ID information.

Power Management
This computer has a built-in power management unit that monitors system 
activity. System activity refers to any activity involving one or more of the 
following devices: keyboard, mouse, floppy drive, hard disk, peripherals 
connected to the serial and parallel ports, and video memory. If no activity is 
detected for a period of time (called an inactivity time-out), the computer 
stops some or all of these devices in order to conserve energy.
This computer employs a power management scheme that supports APM 
(Advanced Power Management) or ACPI
3 (Advanced Configuration and 
Power Interface) which allows for maximum power conservation and 
maximum performance at the same time. 
If your computer is set for APM, you can set timeout values for your 
computer’s devices before power-saving methods are applied to these 
devices. If your computer is set for ACPI, Windows handles all power-saving 
chores for your computer.
Note: 
We recommend you enable power management to prolong your 
battery life.
Power Management Modes
Display Standby Mode
Screen activity is determined by the keyboard, the built-in touchpad, and an 
external PS/2 pointing device.  If these devices are idle for the period 
specified by the LCD backlight Timeout value, the display shuts off until you 
press a key or move the touchpad or external mouse. 
Automatic Dim Feature
The computer has a unique automatic dim  power-saving feature.  When 
the computer is using AC power and you disconnect the AC adapter from the 
computer, it automatically dims the LCD backlight to save power.  If you 
reconnect AC power to the computer, it automatically adjusts the LCD 
backlight to a brighter level.
Hard Disk Standby Mode
The hard disk enters Standby mode when there are no disk read/write 
operations within the period of time determined by the power management 
system.  In this state, the power supplied to the hard disk is reduced to a 
minimum.  The hard disk returns to normal once the computer accesses it.
3Available in the future. 
						

							Chapter 1 27
Standby Mode
The computer consumes very low power in Standby mode.  Data remains 
intact in the system memory until the battery is drained.
There are four ways to enter Standby mode:

Pressing the Standby hotkey Fn-F3

Allowing the waiting time specified by the Standby Timeout value or the 
operating system to elapse without any system activity

Closing the display cover

When the computer is about to enter Hibernation mode (e.g., during a 
battery low condition), but the Hibernation file is invalid or not present
Note: 
f the computer does not enter Standby mode after pressing the 
Standby hotkey, it means the operating system will not allow the 
computer to enter the power-saving mode.
The following signals indicate that the computer is in Standby mode:

The buzzer beeps (when the hotkey is pressed to enter into Standby 
mode)

The Standby indicator lights
Warning: 
Unstored data is lost when you turn off the computer power in Standby 
mode or when the battery is drained.
To leave Standby mode and return to normal mode:

Press any key

Move the active pointing device (internal or external, PS/2 or serial)

Have the Resume Timer set and let it be matched

Open the display cover

Experience an incoming PC card modem event
Hibernation Mode
In Hibernation mode, all power shuts off (the computer does not consume 
any power).  The computer saves all system information onto the hard disk 
before it enters Hibernation mode.  Once you turn on the power, the computer 
restores this information and resumes where you left off upon leaving 
Hibernation mode.
Before the computer can enter Hibernation mode, the Hibernation file created 
by Sleep Manager must be present and valid. 
Then, there are four ways to enter Hibernation mode: 

Pressing the Hibernation hotkey Fn-F4

Allowing the waiting time specified by the Hibernation Timeout value to

elapse without any system activity

When a battery low condition occurs and the Sleep Upon Battery-low 
parameter in Setup is set to [ENABLED]

Invoked by the operating system power-saving modes
Note: 
If the computer beeps but does not enter Hibernation mode after 
pressing the Hibernation hotkey, it means the operating system 
will not allow the computer to enter the power-saving mode.
To exit Hibernation mode, press the power switch.  The computer also 
resumes from Hibernation mode if the resume timer is set and matched.
Warning:
 Do not change any devices (such as add memory) when the computer is in 
Hibernation mode.
Sleep Mode (ACPI)
If ACPI is installed, all power management functions are handled by the 
Windows operating system. In this setup, you do not need to set timout 
values for devices before they enter a power-saving mode.
Sleep mode may be one of three computer power saving modes:  standby, 
hibernation or power off.  Windows automatically determines which of these 
modes to enter.
To enter Sleep mode under ACPI:

Press the Sleep hotkey Fn-F4

Allow the idle times for devices and the computer determined by 
Windows 98 to elapse
How to exit Sleep mode depends upon which power-saving mode the 
computer is in.

Advanced Power Management
This computer supports the APM standard designed to further reduce power 
consumption.  APM is a power-management approach defined jointly by 
Microsoft and Intel.  An increasing number of software packages support 
APM to take advantage of its power-saving features and allow greater system 
availability without degrading performance.
For more information about APM under Windows, refer to your Windows 
user’s manual.
Advanced Configuration and Power Interface
Advanced Configuration and Power Interface (ACPI) is a power-management 
specification jointly developed by Intel, Microsoft, and Toshiba.  ACPI enables 
Windows to control the amount of power given to each device attached to the 
computer.  With ACPI, Windows can turn off peripheral devices when they 
are not in use, thereby saving power.

BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your 
computer’s BIOS (Basic Input/Ouput System).
Your computer is already properly configured and optimized, and you do not 
need to run this utility.  However, if you encounter configuration problems, you 
may need to run Setup.  Please also refer to Chapter 4, Troubleshooting 
when a problem arises.
To activate the BIOS Utility, press F2
 during POST (while the Extensa logo is 
being displayed.
Navigating the BIOS Utility
There are seven menu options: System Information, Basic System Settings, 
Startup Configuration, Onboard Device Configuration, System Security, 
Power Management and Load Default Settings. 
To enter a menu, highlight the item using the 
­¯ keys; then press Enter
.
Within a menu, navigate through the BIOS Utility by following these 
instructions:

Press the cursor up/down keys (
­¯) to move between parameters.

Press the cursor left/right keys (®
¬) to change the value of a parameter.

Press Esc
 while you are in any of the menu options to return to the main 
menu.
Note: 
You can change the value of a parameter if it is enclosed in 
square brackets.
Note: Navigation keys for a particular menu are shown on the bottom of 
the screen.
