• 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.

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.

4. Thermal management
Please refer to Keyboard BIOS specification.
5. Power Management for ACPI mode

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

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.
