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.

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

Power button

LAN (On board)

RTC

Critical low battery

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.

6.4 Power State Transition Diagram

The state transition diagram in ACPI mode is as follows:

From (State)

Leave By Condition

Enter (State)

Power Button

On board LAN

Any key

ACPI OS setting)

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.
