IMPORTANT SAFETY INSTRUCTIONS
When using your telephone equipment, basic safety precautions should always be followed to
reduce the risk of fire, electric shock and injury to persons, including the following:
★
Do not use this product near water, for example, near a bathtub, washbowl, and kitchen
sink or laundry tub, in a wet basement or near a swimming pool.
★ Avoid using a telephone (other than a cordless type) during an electrical storm. There
may be a remote risk of electric shock from lightning.
★
Do not use the telephone to report a gas leak in the vicinity of the leak.
★
Use only the power cord indicated in this manual.

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.
JHT01 Service Manual
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.

JHT01 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.

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.
JHT01 Service Manual
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
2-7
JHT01 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.

JHT01 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 2 seconds
*Measured using the Microsoft BootVis tool.
In addition, total resume time from S3 must be completed within 5 seconds.
