Buttons
Power Button
Under ACPI, the power button action is under the control of the operation system.
• The following is a table of the state transitions in ACPI mode.
Initial Final Comments
Off On Does a normal reboot. Prompts for password if required.
Standby On Restores device states from RAM. Prompts for password if required.
Hibernate On Restores RAM and device states from disk. Prompts for password if
required.
On Standby,
Hibernate(
default) or
Off
. Action depends on OS setting. Can be set to Standby, Hibernate, or
Off(default).
. Note that the Off option is done under the control of the OS, so it is
functionally the same as doing a Start-Shut down but probably quicker.
Power Button Over-ride
Holding down the Power Button for 4 seconds will cause an unconditional transfer to the Off
state without notifying the operating system.
If press power button for less than 4 seconds, the system will enter suspend to RAM or OFF
state according to OS UI setting.
Lid Switch
This section describes the expected behavior of the system when the lid is opened or closed
by the user.
If the system is running under legacy mode:
• Closing the lid will turn off LCD backlight.
If the system is running under ACPI mode:
• The function of lid switch will follow the OS setting in power management (Nothing,
standby, Hibernate or Power off). If standby, the system wakes up when the lid opens. If
nothing, the backlight must still turn off when the lid is closed.
System status indicators
Please refer to Keyboard BIOS specification.
Core BIOS Features
Enhanced IDE Disk Drive Support (EDD)
In addition to AT standard disk drive support, the Phoenix NoteBIOS 4.06 also supports:
• Auto-detection and sizing of all IDE drives.
• Logical Block Addressing(LBA)
• Fast DMA support
• Ultra DMA-33/66/100 support
The CHS translation mode will be used.
Chapter 2-3
Multi Boot
The notebook can support Multi Boot for selecting the boot sequence of hard disk, floppy, CD
ROM, Network Boot in Setup. It identifies all IPL (Initial Program Load) devices in the system
and attempts to boot them in the order specified in Setup.
Quiet Boot
Quiet Boot replaces the customary technical messages during POST with a more visually
pleasing and comfortable display (OEM Logo screen). During POST, right after the
initialization of VGA, The notebook displays an illustration called the OEM screen during
system boot instead of the traditional POST screen that displays the normal diagnostic
messages.
The OEM Logo screen stays up until just before the operating system loads unless:
• Press <Esc> to change the boot order.
• Press <F2> to enter Setup. (When pressed, need to show “Entering Setup…”)
• Press <F12> to boot from LAN (When pressed, need to show “Booting from LAN…”)
• Whenever POST detects a non-terminal error, it switches to the POST screen near the
end of POST, just prior to prompting for a password.
• If the BIOS or an option ROM requests keyboard input, the system switches over to the
POST screen with prompts for entering the information. POST continues from there with
the regular POST screen.
New Interrupt 15h extensions
The BIOS must support the recently defined standard INT 15 extensions:
Big Memory
Big memory support that can reporting greater than 64 megabytes of RAM. The notebook
supports the INT 15h big-memory reporting functions of E801h, E881h, and E820h. This
feature reports all available extended memory (both below and above the 64MB limit) using
both a real mode (E801h) and a 32-bit protected mode (E881h) interface. Operating systems
can access the real-mode interface through the standard INT 15h call. They can access the
protected-mode interface through a 32-bit interrupt call, much like the EISA protected-mode
interface. The Microsoft-defined E820h function returns a complete memory map through a
series of repeated calls.
Boot Block
The Flash ROM used in many systems today offer the customer the advantage of
electronically reprogramming the BIOS without physically replacing the BIOS ROM. This
advantage, however, does create a possible hazard: power failures or fluctuations that occur
during updating the Flash ROM can damage the BIOS code, making the system unbootable.
To prevent this possible hazard, many Flash ROM include a special non-volatile region that
can never be erased. This region, called the boot block, contains a fail-safe recovery routine.
If the boot block finds corrupted BIOS, it prompts the end user to insert a diskette, from which
it loads several files that replace the corrupted BIOS on the Flash ROM with an uncorrupted
one.
Plug-n-Play (PnP) Support
To achieve the goal of PnP, a POST conflict detection and resolution (CDR) module, and a
run-time services module will be integrated into the system BIOS.
The PnP runtime service module includes multiple interfaces so that the system can support
the current DOS/Win3.1 non-PnP drivers, as well as Win95 operating system that include
specific support for the PnP BIOS specification.
Chapter2-4
Security Features
Security features to be supported are passwords, electronic serial number, PC identification
string.
The Electronic Serial Number provides a unique way of identifying an individual notebook.
PC Identification strings allow the user or administrator to personalize the notebook for asset
tracking or identification if it is lost.
The Passwords, Serial Number, and PC Identification strings are to be stored in EEPROM.
2 Level Passwords
The notebook supports two levels of password protection. The password support consists of a
User Password and an Administrator Password. They each contain up to eight characters,
and are stored in EEPROM. Using the administration password to enter the setup utility allows
the user to access all the configurable fields. Whereas using the user password only allows
the user to configure a limited number of fields.
When the password is enabled, the notebook may display a suitable password prompt on the
main display in the following situations:.
• Turning on from off states. (No BIOS suspend/resume password)
• Entering to Setup.
The User will attempt to enter a password, then press ENTER. If the User fails to enter the
password in three tries the system will be halt.
User Password
The user can choose:
• The password will never be required
• Be required to boot.
• The user password may not be set unless the administrator password is set. If the user
wishes to only have one password then the administrator password is used.
Administrator Password
There are three primary uses for the Administrator Password:
• Protect users from changing system configuration that could cause the notebook to
malfunction.
• As the users password if only a single password is desired.
Passwords and Setup
There are individual checkbox items in Setup to allow the user to specify when to require a
password. The wording of these options should be:
Password Required to:
Boot [Enabled]
The following table lists the items in the Setup utility which can be modified by the User.
Time & Date
User password
While setting new password, three failures to enter the old password will result in the system
turning off.
Valid Password Characters
Valid Password Characters
Chapter 2-5
• The numbers 0 to 9.
• The letters A to Z (not case sensitive).
The password is stored as scan codes.
Electronic Serial Number
The electronic serial number is a ten (10) byte string which matches the manufacturing serial
number on the bottom of the notebook. The BIOS must display the electronic serial number in
the boot screen and in Setup. The format of the line should be
Serial Number: SSSSSSSSSS
where SSSSSSSSSS is the electronic serial number. The format of the serial number is:
CCYWWNNNNN
Where
CC is a two character country code (TW for Taiwan).
Y is the year of manufacture (7 = 1997, 8 = 1998, etc.)
WW is the week of manufacture (1 to 52)
NNNNN is the unit number (see below).
Unit number is a number from 00000 to 99999 and is incremented for each unit produced.
The unit number is reset at the beginning of each week. Before displaying the serial number,
the BIOS must check for the special
number is detected, the BIOS should display the message:
INVALID ELECTRONIC SERIAL NUMBER
ENTER THE SERIAL NUMBER NOW:
The BIOS must then force the user to enter the serial number and program the entered serial
number into the EEPROM. The BIOS must perform validity checks on the serial number
entered.
System boards sent to service must be preprogrammed with this invalid serial number. This is
to insure that when a service technician swaps a new main board into a system that he/she
sets the serial number to match the serial number of the system.
This same electronic serial number is used for the serial number returned by the SM BIOS.
Software Password Backdoor
Because users occasionally forget their password we need a method of removing the
password for them. This method must involve little risk to the security of the password system
in general.
The method is that the User calls up Customer Support, Support tells them to press some
*special key combination which causes a
to support representative who then use their secret decoder ring to generate a

During the password request process, three failed attempts to enter the backdoor password
will also cause system turning off.
The back door password process can only be held on the cold boot.
Thermal management
There are two types of cooling techniques used for thermal management. The first type is
passive cooling where the CPU speed is reduced or other devices power consumption is
Chapter 2-6
reduced in an effort to reduce heat generation. The second type is active cooling where a fan
is turned on to cool the system.
In non-ACPI mode(Legacy Mode), the thermal management is achieved by controlling the fan
depend on the temperature. Besides turning the fan on and off. The system may also be
shut off whenever the temperature can’t be reduced even the fan are spinning in the full
speed. The system will be turned off immediately when it’s over-heating (over 85°C). The fan
will be turned off when temperature is under 65°C. The table below listed the control point of
temperature changes:

Power Management
Introduction
The notebook supports ACPI power management modes. The system will dynamically switch
to ACPI mode for configuration and power management when an ACPI OS is loaded.
System Time-outs
The system Time-outs include the Standby time-out, the Suspend time-out, and the Hibernate
time-out.
System Time-outs are handled by the operating system in ACPI mode. BIOS time-outs must
be disabled. System time-outs are set using the control panel power applet.
System Power Management
The overall system can be in one of five system power states as described below:
Legacy Mode ACPI mode Power Management
Off Mech. Off (G3) All devices in the system are turned off
completely.
Soft Off (G2/S5) OS initiated shutdown. All devices in the system
are turned off completely.
On Working (G0/S0) Individual devices such as the CPU and hard
disk may be power managed in this state.
Standby (S1) CPU in Stop Clock state
VGA Standby, turn off backlite
PCMCIA Standby
Audio Power Down
Hard Disk Spin Down motor
Super I/O Low Power Mode
Suspend to RAM (S3) CPU set power down
VGA Suspend
PCMCIA Suspend
Audio Power Down
Hard Disk Power Down
CD-ROM Power Down
Super I/O Low Power mode
Save to Disk (S4) Also called Hibernate state. System Saves all
system states and data onto disk prior to power
off the whole system.
Chapter 2-7
Device Power Management
The device specific power management supported by this notebook includes the CPU and the
hard disk.
CPU power management
• ACPI mode
The operating system detects when the system is idle and places the CPU in one of the 3
CPU low power states (C1, C2 or C3) depending on how much latency it believes the
system can afford.
The C1 state is simply the CPU halt instruction. The C2 state is the CPU stop grant state.
The C3 state is the CPU stop clock state. The CPU stays in this state until an interrupt
occurs.
Hard Disk
• ACPI mode
Newer OSes use the spin down timer of the hard drive to set time-outs. The user can sets
the hard disk spin down time-out in the control panel power applet.
System Wake Up Sources
The table below lists the wake up events for all low power states:
Events S1 S3 S4 Process required

*2: Activity of the USB device is dependent on the driver support.
Power Button
The power button will wake the system from any low power state as described in the Power
Button section.
Real Time Clock Alarm
The Real Time Clock alarm interrupt will wake the system from standby, suspend.
Power Management – ACPI
Introductions
The Advanced Configuration and Power Interface (ACPI) is a well-specified power
management and configuration mechanism. It evolves the existing collection of power
management codes, APM, PnP BIOS, ..etc.
Power State Transition Diagram
The state transition diagram is identical to the one in APM mode.
Time-outs while On AC Power
OS determines the behavior of the feature.
Embedded controller
The keyboard controller will act as the ACPI embedded controller and support the ACPI EC
protocol and interface.
SCI/SMI events
All ACPI OS controllable events will be triggered as SCI. Otherwise SMI will be triggered.
PC2001
The notebook must meet Microsoft Logo requirements in accordance with the PC2001 Design
Guide and the Microsoft Logo test programs.
Miscellaneous Features
Single BIOS ROM
The system BIOS and Keyboard BIOS share one single flash ROM. The size of the flash
ROM is 512KB.
USB Support
This feature allows the use of a USB keyboard to access BIOS Setup and to be used in DOS
without additional drivers.
IDE interface
The IDE device supported master channel.
Flash utility – one BIOS ROM only
The flash utility can be used to program both system and keyboard BIOS at the same time.
Chapter 2-9
EEPROM
There is one EEPROM which is used to store many important system and user data in the
notebook The size of the EEPROM is 2K bytes.
Password Protection
Password and Security support will be implemented in this model. See the PhoenixBIOS 4.0
User Manual for sample screen and the description of Password and Security support.
VGA Support
This section describes the expected behavior when a video monitor is connected to the VGA
port on the notebook or port replicator.
The BIOS will use both of the RGB and pin 11 methods to determine the presence of an
external VGA monitor. Either case meet will indicate an external VGA monitor is present.
The BIOS setup utility will have a menu for setting up the behavior of the external VGA port
according to user preference. There are two settings:
Setting 1, AUTO: Auto-select External VGA if attached(CRT only), LCD if external not
attached.
Setting 2, BOTH: Both External VGA and LCD always on.
When setting 1 is selected the BIOS will automatically turn the internal display off and the
external monitor on, whenever an external monitor is detected. Otherwise it will enter LCD
only mode (with the backlite off if the cover lid is closed). This means that the BIOS must
check for the external video being present during POST; on resume from standby, on resume
from suspend to RAM, on resume from hibernate; on warm dock, on hot dock, on hot undock,
and on warm undock.
When setting 2 is selected, the BIOS will always turn on both the internal display and external
monitor regardless of whether an external monitor is detected.
The hot key for switching the external video (Fn + F5) must only make a temporary change. It
′
must not change the user
external video port. Also the hot key must not check to see if an external monitor is detected
before switching to external only mode. It should just toggle between internal only, both, and
external only (without regard to monitor detect). The hot key setting will not survive suspend
to RAM, hibernate. In these cases the mode should be set back to the setting stored in
CMOS.
s preference in CMOS, it will just change the current state of the
Internal Pointing Device Support
Added a new BIOS setup to enhance the PS/2 pointing devices
PS/2 Pointing Devices:
Auto-Selected: Disable internal pointing devices if external PS/2 mouse is present.
Simultaneous:
• If an external PS/2 mouse is detected, it will be enabled. If USB mice are detected, they
will be enabled as well. If an external mouse contains a third mouse button, it will function
as expected.
• Double click the Mouse icon in the Windows2000/XP Control Panel to adjust pointer
speed, double click speed, right-handed versus left-handed button settings, and pointer
appearance. The settings in this applet apply to all the external and internal pointing
devices in the system. Except as described below, there are no individual pointing device
adjustments available.
The internal pointing device is always enabled. Any external pointing device
connected will also be enabled at the same time.
Chapter 2-10
• Tapping (or double tapping) on the TouchPad is equivalent to a single (or double) left
mouse click. The Synaptics TouchPad driver will be available on the hard drive and the
customer may choose to manually install it. The Synaptics TouchPad driver should only be
installed after first selecting Touch pad only in BIOS Setup.
• Hold down center button of external PS/2 mouse: While holding down the center button of
an external mouse, move the mouse. This will cause the window to move. If the center
button is not held down, all pointing devices function normally.
• Use TouchPad: The TouchPad is locked in as the Scrolling or Magnifying Glass device.
Sweeping across the TouchPad causes the window to move. The other pointing devices
function normally.

We have several keys support keypad mode. List as below:
• One channel is dedicated for the keyboard and mouse data transfer(host address 60h and
64h). The Keyboard and Mouse channel of KBC is compatible to the legacy 8042 host
interface. It is base on two registers: Command/Data and Status
• The KB-BIOS interrupt generates IRQ1(Keyboard) and IRQ12(Mouse) for system.
Power management interface transfer port
• The other for the power management function(host address 62h and 66h). The Power
Management channel of KBC structure and operation are similar to those of the
Keyboard/Mouse channel.
Support three independent devices
• The KBC provides three data transfer channels. Each channel has two quasi-bidirectional
signals that are used for the direct interface to an external keyboard, mouse or any other
PS/2 compatible pointing device.
• The three channels are identical and thus allow the connector ports to be interchangeable.
Devices PnP configuration
Hot Plug-and-Play support
• The KBC watches both external devices, checking if the devices have recently been
plugged in or unplugged. The Hot pluggability of external PS2 devices feature detects the
attachment or removal of these devices.
Hot swapping control
• When the device is plugged in, the software automatically initializes the state of that
device, checks port swapping, and setup the KBC to handle dual-device operation. In dualdevice operation, the internal device is set in the same state as external device. When the
external device is unplugged, the internal device becomes the primary device.
ACPI EC interface Specification support
ACPI interface support
• The KBC provides support for Advance Configuration and Power Interface
specification(ACPI) Embedded Controller interface.
EC command support
• The 2nd (Power Management) host interface channel of the KBC is dedicated to this
function.
• All EC commands defined in the ACPI specification - Read/Write, Burst Mode
enable/disable and Query command - are supported.
Chapter 2-36
Internal keyboard change Configuration
US/UK/JP country option
• The KBC supports three country selection by KBD_SEL application.
• You can key in KBD_SEL get the syntax for your option at DOS prompt.
Sticky key support
• Press shift key 5 times will enable sticky key function.Turns on StickyKeys,which allows
you to press a modifier key(CTRL,ALT,or SHIFT),or the windows logo key, and have it
remain active until the next time you press a key other then CTRL,ALT,SHIFT,or windows
logo key. This is useful for people who have diffculity pressing two keys simultaneously.

Safety Precautions
Before you begin disassembly, read the following safety precautions and ob serve them
carefully as you work.
DANGER:
1. Always use the lithium ion battery pack or backup battery that is authorized by the
manufacturer or compatible with the unit. Since other battery packs have different
specifications, they may be incompatible with the unit, and may burst or explode. Heating or
disassembling the battery pack could cause leakage of alkaline solution. Throwi ng the battery
pack into a fire could cause the battery pack to explode.
2. The power supply, FL inverter and other components carry high voltages. To avoid the risk of
electric shock when you need to turn on the power of a partially disassembled computer to
check its operation, be very careful not to touch connectors or com ponents. Also, do not
disassemble individual components in first-level maintenance.
WARNING:To avoid the risk of electric shock or other injury:
1. Always turn the power off and disconnect the AC adaptor from the power source.
2. Remove any metal jewelry or accessories such as necklaces, bracelets, or rings. Batteries in the
computer retain an electrical charge so there is danger of electrical shock even when the
computer is disconnected from an AC power source.
3. Never work with wet or damp hands.
4. The computer contains sharp edges and corners: be careful not to injure yourself.
5. Make sure that all replacement components meet the specifications for the computer and that all
cables and connectors are securely fastened.
CAUTION:To avoid damage to the computer:
1. When you change a component, be sure the replacement component meets the required
specifications. Never use foreign parts.
2. Metal objects such as screws or paper clips which fall into the unit can cause a short-circuit, fire,
or other internal damage.
3. When assembling the computer, make sure you use the correct screws to secure the various
pieces in place. Screw sizes are listed in their corresponding figure. Make sure all scre ws are
securely fastened. Loose screws can cause short circuits, resultin g in heat, smoke, or fire.
4. Before removing an module or other component, make sure all cables to the component have
been disconnected.
5 . If you use AC power, be sure to use the cable that came with the computer or one recommended
by the manufacturer.
Chapter5-3
Before You Begin
Look over the procedures in this section before you begin disassembling the computer.
Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by
removing the AC adaptor and the battery pack.
1. Do not disassemble the computer unless it is operating abnormally.
2. Use only the correct and approved tools.
3. Make sure the working environment is free from the following elements whether you
are using or storing the computer.
Ö Dust and contaminates
Ö Static electricity
Ö Extreme heat, cold and humidity
4. Do not perform any operations that are not necessary and use only the described
procedures for disassembling and installing modules in the computer.
5. After removing parts from the computer, place them in a safe place away from the
computer so they will not be damaged and will not interfere with your work.
6. You will remove and replace many screws when you disassemble the computer. When
you remove screws, make sure they are placed in a safe place and identified with the
correct parts.
7. When assembling the computer make sure you use the correct screws to secure the
various pieces. Screw sizes are listed in their corresponding figures.
8. The computer contains many sharp edges and corners, so be careful not to injure
yourself.
9. After you have replaced a component, make sure the computer is functioning properly
by performing the appropriate test on the component you have fixed or replaced.
Chapter 5-4
Disassembly Procedures
The computer has two basic types of cable connectors:
Pressure Plate Connectors
Standard Pin Connectors
To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector’s
plastic pressure plate and slide the cable out of the connector. To connect the cable to a
Pressure Plate connector , make sure the pressure plate is fully lifted and slide the cable into the
connector. Secure the cable in place by pushing the sides of the pressure plate down so the
plate is flush with the sides of the connector. Gently pull on the cable to make sure the cable is
secure. If you pull out the connector, connect it again making sure the connector’s pressure
plate is fully lifted when you insert the cable.
Standard pin connectors are used with all other cables. These connectors can be connected
and disconnected by simply pulling them apart or pushing them together.
Assembly Procedures
After you have disassembled the computer and fixed or repaired the problem that was causing
the computer to operate abnormally, you will need to reassemble the computer.
While assembling the computer, remember the following general points:
Take your time. Most problems arise when you get in a hurry assembling the
computer.
Make sure all cables and connectors are securely fastened.
Before securing the module or other parts, make sure that no cables will be pinched
by screws or the module.
Check that all latches are closed securely.
Make sure all the correct screws are used to secure all components. Using the wrong
screw can either damage the threads on the screw or the head of the screw and may
prevent proper seating of a module.
After installing a component in the computer, confirm that the component and the computer are
functioning properly.
Chapter 5-5
