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.
Chapter 2-4

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
password administrator).
which they tell the user to type in. This removes (deletes) all passwords (user and
invalid′ serial number (INVALID000). If this special serial
secret code′ to be displayed, the user describes this
super-
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:
Temperature Fan Off Fan on(100%) System Off < 62℃
65℃ > 85℃

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 Hot Key(*1) - - - ­Power button V V V ­Lid open V V - ­Lid close - - - ­Modem Ring (Mini-PCI Modem) V V - ­Modem Ring (USB/PCMCIA Modem) - - - ­Modem Ring (Serial Port Modem) - - - ­LAN (Mini-PCI NIC) V V - ­LAN (USB/PCMCIA NIC) - - - ­AC/Battery - - - V Thermal - - - V RTC V V - ­COM/LPT/KB/Mouse/FDD/HDD - - - ­Audio/Video activity - - - ­PCMCIA - - - Driver USB(*2) - - - Driver Module swap---Battery - - - V Module swap---non Battery - - - V CRT(no event) plug/unplug - - - V Hot Plug PS/2 devices - - - KB only

Field ‘Process Required’ identifies that further process for the occurred events must be processed during wake up or resume procedure.
*1: Hot keys are not wake up source of standby, suspend to RAM and Hibernate states. *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.

Two host interface channels support

Keyboard and mouse interface transfer port
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.
Chapter 5-3
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.
