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.


2-6

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.

• 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

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


2-8

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 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 S3 S4 S5 Process required Any key O X X X Power button O O O X LAN (On board) O O X O RTC O O X O Critical low battery O X X O

Field ‘Process Required’ identifies that further process for the occurred events must be processed during wake up or resume 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.

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.


2-9

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 2 seconds

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

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.


2-34

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.

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.
