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

JHL90 Service Manual

• 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.

JHL90 Service Manual

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.

2-6

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

JHL90 Service Manual

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.

12.11 Thermal Status Report and Fan Control

EC will control fan on/off function according to the CPU temperature (EC will
get temperature from thermal sensor through SMBus). Fan will be off when
temperature below speed 1 speed down temperature, and if temperature over EC
Shutoff temperature five times, EC will auto turn off system to protect CPU. The
following table is detailed settings.

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

Fan 1

RPM

4200

• 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.

2-35

JHL90 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 dual­device 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/JP country option

• The KBC supports three country selection by KBD_SEL application 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

12.16.2 Sticky key support

• Press shift key 5 times will enable sticky key function. Turns on Sticky Keys,

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 difficulty pressing two keys simultaneously.

12.16.3 Internal Keyboard can support wake-up system to resume S3

• Press any key with internal keyboard in standby mode, system will resume

automatically.

12.16.4 Internal Key-Pad mode control

• The key pad mapping shows as below.

Notes:

• The inverter can work in 7.5V input voltae (continuous), but 7.5V electronic

characteristic will not be care. (Note: the display must be normal and can not
glitter or become dark)

• Limited lamp maximum current by DAC_BRIG signal:

When DAC_BRIG voltage is 0V and INV_PWM enables (100%), lamp has
max.-limited current.

When DAC_BRIG voltage is 3.3V and INV_PWM enables (100%), lamp has
min.-limited current.

When add 1V DAC, the 100% Lamp current will decrease 0.5mA.
DAC_BRIG signal comes from system chipset with internal resistance of 3KΩ.

• Inverter operating frequency should be within specification (45~65kHz) at

max. and min. brightness load.

• INV_PWM enable implies INV_PWM signal is High level (On duty cycle is

100%). It is a square wave of 150Hz to adjust backlight brightness that is a
function of PWM duty cycle. Backlight brightness is maximum value under
INV_PWM at 100% and brightness is minimum under INV_PWM at 30%.

• The system interface signals belong to 3.3V.

• Please make sure open lamp output voltage should be within starting voltage

specification.

• Inverter should pass human body safety test.

• Inverter should no smoking by any component open / short test

• Transformer voltage stress should not be over 85% under any condition (turn

on overshoot transient and line transient).

• Audio noise should be less than 36dB at 10 cm distance.

4.6 Safety Protection

4.6.1 Open lamp protection:

When inverter is on open lamp status, any component on inverter should be O.K
and inverter is no damaged, no fire and no arcing. If inverter can’t shunt down
during open lamp happen, inverter must pass below conditions:

• Human body test.

• Open lamp burning: Inverter burns for 24 hours at open lamp status. No parts

damage.

4.6.2 Human body safety test:

Short inverter output, transformer secondary output to GND by a 2KΩ resistor
which connects one end to GND and another one to those outputs. They should
meet output current limitation requirement as follow. Output current I is the
current that flows through 2KΩ resistor.

• Output current I ≤ 0.7mA, if frequency f ≤ 1KHz

• Output current I ≤ 0.7mA * f (kHz), if f ≥ 1KHz.

However, output current should be less than 70mA even frequency is more than
100KHz.

4.6.3 Abnormal test:

Any one component is short or open; inverter should be no fire, no arcing. And
result must meet output current limitation requirement.
