2.2 Buttons 2.2.1 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.

2.2.2 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.

2.2.3 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.

2.3 System status indicators Please refer to Keyboard BIOS specification.

3. Core BIOS Features 2-6


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.

• 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.

3.4 New Interrupt 15h extensions The BIOS must support the recently defined standard INT 15 extensions:

3.4.1 Big Memory

2-7


Big memory support can report 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.

3.5 Plug-n-Play (PnP) Support To achieve the goal of PnP, 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, as well as Win98 operating system that include specific support for the PnP BIOS specification.

4. Thermal management Please refer to Keyboard BIOS specification.

2-8


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 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.

2-9


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 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:

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 Boot and Fast Resume BIOS must hands off the control to the operating system within the following time limits:

Required S5->S0 7sec S4->S0 7sec S3->S0 250msec

*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

2-14


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.

2-15


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 share one single flash ROM. The size of the flash ROM is 1MB.

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 USB flash stick, 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 flash stick

Hold down Fn + B keys.

Plug-in AC adapter and make sure it is powered.

2-16


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 USB flash stick 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.

2-49


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.

• 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.

Testing and Troubleshooting:

The purpose of this chapter is to provide a systematic method of isolating problems you may have with the KHLB2 series Notebook Computer. We assume that you have a basic understanding of DOS-based computer systems as well as knowledge of standard troubleshooting procedures. This manual is written under the assumption that the problems are indeed related with Notebook itself. The improper usage and application software problems are excluded in this chapter. The system BIOS Beep Code is an integrated unit to detect some errors in the system board. This beep code will give immediate identification of certain system board problems. If the troubleshooting procedure is followed step by step, it can efficiently isolate the problem and the problem can be solved easily.

1. PERFORM VISUAL INSPECTION Check the following:

• Power cords are properly connected and secured

• Power supply is adequate for operation

• There are no obvious shorts or opens

• There are no obviously burned or heated components

• All components appear normal

2. Troubleshooting Flowchart Use the flowchart in Figure 6-1 as a guide for determining which troubleshooting procedures to execute. Before going through the flowchart steps, verify the following:

• Ask the user if a password is registered and, if it is, ask him or her to enter the password.

• Verify with the customer that VISTA32 is installed on the hard disk. Operating systems that were not preinstalled by Compal can cause the computer to malfunction.

• Make sure all optional equipment is removed from the computer.
