2. System Controls

2.1 Buttons

2.1.1 Power Button

The activity of the power button is as follows:  If system is Off/Hibernate: System will be turned on while Power switch is

depressed by more than 100 ms

 If system is in Standby state: System will resume while Power switch is

depressed by more than 100 ms.  If system on with legacy mode: depress this button will turn off power. If system is running in ACPI OS, the power button acts as the sleep button, and let

OS controls the policy of power button which is defined in Power Option under the OS.

2.1.2 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.

2.1.3 Lid switch

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 operating system will determine what action to take when the lid is opened

and closed. The function of lid switch will follow the OS setting in power management (Nothing,

Standby or Hibernate). If nothing, the backlight must turn off when the lid is closed.

2.2 System status indicators

Please refer to Keyboard BIOS specification.

3. Core BIOS Features

3.1 Multi Boot

The notebook can support Multi-Boot for selecting the boot sequence of Hard Drive, Removable Devices, CD-ROM/DVD Drive and Network in Setup.

3.2 Quiet Boot

Quiet Boot replaces the customary technical messages during POST with a more visually pleasing and comfortable display (OEM 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 screen stays up until just before the operating system loads unless:  Pressing <Esc> to switch to the POST screen and the boot process will

continue until the end of POST.  Pressing <F2> to enter Setup.

NBLB2 Service Manual

 Pressing<F12>to enter Boot Menu  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 request 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.

3.3 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.

4. Thermal management

Please refer to Keyboard BIOS specification.

5. Power Management for ACPI mode

5.1 Introduction

The notebook supports ACPI. The system will dynamically switch to ACPI mode for configuration and power management when an ACPI OS is loaded.

When ACPI is not loaded and enabled, the power management function will be disabled.

5.2 System Time-outs

If the system is running in ACPI mode, system Time-outs is handled by the operating system. BIOS time-outs are disabled. System time-outs are set using the control panel power applet.

5.3 System Power Management

The overall system can be in one of the system power states as described below:

ACPI mode

Power Management

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.

Working (G0/S0)

Individual devices such as the CPU and hard disk may be power managed in this state.

S3 Sleeping State

CPU set power down VGA Suspend New Card Suspend Audio Suspend Hard Disk Power Down ODD Power Down Super I/O Power Down

NBLB2 Service Manual

S4 Sleeping State

System Saves all system states and data onto disk prior to power off the whole system.

5.4 Device Power Management

Under ACPI mode, the device specific power management supported by this notebook includes the CPU throttling, monitor power management and the hard disk.

5.4.1 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, C3 up to C6) 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 stops clock state. The CPU stays in this state until an interrupt occurs.

5.4.2 Hard Disk

The operating system uses the spin down timer of the hard drive to set time-outs. The BIOS time-out of the hard disk must be disabled in ACPI mode. The user can sets the hard disk spin down time-out in the control panel power applet.

5.4.3 Display Device

The monitor can be turned off after a period of no activity based on the settings of

the OS.

5.4.4 System Wake Up Sources

The table below lists the wake up events for all low power states:

Events

Process required

Any key

O X X

Power button

O O O

LAN (On board)

O O X

RTC O O

O X X

Field „Process required‟ identifies that further process for the occurred events must be processed during wake up or resumes procedure.

5.4.4.1 LAN

LAN (On board)

The function of waking up the system from standby (DC/AC)/hibernation (AC mode) is supported.

5.4.4.2 Real Time Clock Alarm

The Real Time Clock alarm interrupt will wake the system from Standby (DC/AC) / Hibernation (AC mode)

5.4.4.3 Critical Low Battery

Critical low battery event can wake the system from Standby (DC mode) in ACPI mode.

NBLB2 Service Manual

5.5 Hibernation

To support the hibernate state, the save to disk partition or file will be created by the operating system if the user select to enable the hibernation.

It is the responsibility of the operating system to save the system state to a disk file and restore the system state when it is turned back on.

NBLB2 Service Manual

6. ACPI (Advanced Configuration and Power Interface)

6.1 Introduction

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, and Etc.

6.2 ACPI Sleep Status

BIOS must support the following sleep states – S3, S4 and S5.

6.3 Fast Resume

BIOS must hands off the control to the operating system within the following time limits:

Required

S3->S0

2seconds

*Measured using the Microsoft BootVis tool. In addition, total resume time from S3 must be completed within 5 seconds.

6.5 Storage Devices and Batteries

Possible storage devices are FDD, HDD, CD-ROM and DVD-ROM  Floppy Disk and Hard Disk, CD-ROM and DVD-ROM

The BIOS must report the correct types of these devices if the drive is installed in the system during POST. Two devices, which belong to the same category, are not supported in this notebook.

 Batteries

The BIOS must follow ACPI specification and report the correct number of the installed battery and status.

6.6 Bootable Device

The system is capable of booting from onboard HDD, CD ROM, DVD-ROM, external USB Floppy and USB ATA Flash device.

6.7 Embedded controller

The keyboard controller will act as the ACPI embedded controller and support the ACPI EC protocol and interface.

NBLB2 Service Manual

7. PC2001

The notebook must meet Microsoft Logo requirements in accordance with the PC2001 Guide and the Microsoft Logo test programs.

8. Miscellaneous Features

8.1 Single BIOS ROM

The System BIOS and Keyboard BIOS are separately The Size of System BIOS is 2MByte Include BIOS and Ignition ME) The Size of Keyboard BIOS is 128K (eeprom is inside EC BIOS area)

8.2 USB Support

This feature allows the use of a USB keyboard to access BIOS Setup and to be used in DOS without additional drivers. USB floppy boot and Crisis Recovery from USB floppy is also supported. The driver provides other USB devices support after loading the operating system.

8.3 Flash utility – one BIOS ROM only

The flash utility can be used to program both system and keyboard BIOS at the same time.

8.4 Crisis Recovery

This feature provides an opportunity for system that cannot boot up. With a crisis floppy diskette, the system can perform crisis recovery by using internal PS2 keyboard.

To perform crisis recovery using keyboard, do the following: Power off the system. Plug-in the USB floppy drive with crisis floppy diskette inserted. Hold down Fn + B keys. Plug-in AC adapter and make sure it is powered. Power on the system from off state (i.e. cold boot) while holding down <Fn+B> key. After POST, release <Fn+B> key. The system should boot from floppy and perform

crisis recovery action.

8.5 VGA Support

This section describes the expected behavior when a video monitor is connected to the VGA port on the notebook .The feature needs VGA driver support

The BIOS will use both the RGB and pin 11 methods to determine the presence of an external VGA monitor.

Video modes supported on the secondary display path (need VGA driver support)

Supported video modes and timings please refer to the technical reference of VGA vendor. In particular, text mode and standard VGA modes are not supported.

12.12 Three host interface channels support

12.12.1 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 EC-FW interrupt generates IRQ1 (Keyboard) and IRQ12 (Mouse)

for system.

12.12.2 Power management interface transfer port

 The other channel is 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.

12.12.3 Extra transfer port

 This channel (host address 68h and 6Ch) was created to prevent

conflict with the other channels.

12.13 Support three independent devices through PS/2 channel simultaneously

 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.

12.14 Devices PnP configuration

12.14.1 Hot Plug-and-Play

 The KBC watches both external devices, checking if the devices have

recently been plugged in or unplugged. The Hot plug ability of external PS2 devices feature detects the attachment or removal of these devices.

NBLB2 Service Manual

12.14.2 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 dual-device 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.

12.15 ACPI EC interface Specification support

12.15.1 ACPI interface support

 The KBC provides support for Advance Configuration and Power

Interface specification (ACPI) Embedded Controller interface.

12.15.2 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.

12.16 Internal keyboard change Configuration

12.16.1 US/UK/PA/JP country option

 The KBC supports three country selections by KBD_SEL application,

and one EX type for another country.

 You can key in KBD_SEL get the syntax for your option at DOS prompt.

e.q. KBD_SEL S US keyboard KBD_SEL K UK keyboard KBD_SEL J JP keyboard KBD_SEL E EX keyboard
