							1-26Service Guide1.4.22Charger
To charge the battery, place the battery pack inside the battery compartment and plug the AC adapter into
the notebook and an electrical outlet.  The adapter has three charging modes:
· Rapid mode
The notebook uses rapid charging when power is turned off and a powered AC adapter is connected to
it.  In rapid mode, a fully depleted battery gets fully charged in approximately two hours.
· Charge-in-use mode
When the notebook is in use with the AC adapter plugged in, the notebook also charges the battery
pack if installed.  This mode will take longer to fully charge a battery than rapid mode.  In charge-in-
use mode, a fully depleted battery gets fully charged in approximately six to eight hours.
· Trickle mode
When the battery is fully charged, the adapter changes to trickle mode to maintain the battery charge
level.  This prevents the battery from draining while the notebook is in use.

1.5.1BIOS
The BIOS is compliant to PCI v2.1, APM v1.2, E-IDE and PnP specification.  It also defines the hotkey
functions and controls the system power-saving flow.
1.5.1.1Keyboard Hotkey Definition
The notebook supports the following hotkeys.

The system can boot from the FDD, External FDD, HDD, CD-ROM.  The user can select the desired
booting process to boot the system.  If the CD-ROM is bootable, the BIOS will override the other process to
boot the system directly.

							1-32Service GuideON MODENormal full-on operation
STANDBY MODEThe notebook consumes very low power in standby mode.  Data remain intact in the system memory until
battery is drained.
The necessary condition for the notebook to enter standby mode is that the reserved disk space size for
saving system and video memory is insufficient so the notebook is unable to enter hibernation mode.  In this
situation, there are three ways to enter standby mode:
· Press the standby/hibernation hotkey 
Fn-F7 ()
· Set a value for the System Standby/Hibernation Timer in Setup.  If the waiting time specified by this
timer elapses without any system activity, the notebook goes into standby mode.
· Invoked by the operating system power saving modes
The following signals indicate that the notebook is in standby mode:
· The buzzer beeps (when you press the standby/hibernation hotkey)
· The indicator light flashes
To leave standby mode and return to normal mode, press the any key.  If an incoming PCMCIA modem
event occurs and the Modem Ring Wake Up From Standby is enabled, the system returns to normal mode.
Table 1-36Standby Mode Conditions and DescriptionsConditionDescriptionThe condition to enter
Standby Mode· “Hard Disk Drive” is [Disabled] in System Security of BIOS SETUP.
· “Hard Disk 0” is [None] in Basic System Configuration of BIOS SETUP.
· HDD has not located enough free contiguous disk space generated by Sleep Manager
and this free space is not corrupted.
· Standby/Hibernation Timer times-out or Standby/Hibernation HotKey pressed and
there is no activity within 1/2 second.The condition of
Standby Mode· Issue a beep.
· Flash standby LED with 1 Hz frequency.
· Disable the mouse, serial and the parallel port.
· The keyboard controller, HDD and VGA enter the standby mode.
· Stop the CPU internal clock.
· All the functions are disabled except the keyboard, battery low warning and modem
ring wake up from standby (if enabled).The condition back to
On ModeAny one of following activities will let system back to Normal Mode:
· Any keystroke (Internal KB or External KB)
· Modem ring.HIBERNATION MODEIn hibernation mode (also known as zero-volt hibernation-to-disk mode), power shuts off.  The notebook
saves all system information onto the hard disk before it enters hibernation mode.  Once you turn on the
power, the notebook restores this information and resumes where you left off upon leaving hibernation
mode.
