Operating on Battery Power

This chapter contains the information you need to know to operate the
notebook on battery power.

2.1 Battery Pack

Whenever possible, use the AC adapter. The battery will come in handy
when you travel or during a power failure. It is advisable to have an extra
fully-charged battery pack available for backup. The battery pack is
installed in the battery compartment. Before removing the battery pack,
make sure the notebook power is off. Follow these steps to remove the
battery.

1. Press the cover release and slide
the cover out.

Chapter 2

2. Pull out the battery using the cloth
strip attached to the end of the
battery pack.

Operating on Battery Power 2-1

Do not expose battery packs to temperatures below 0ºC (32ºF)
or above 60ºC (140ºF). This may adversely affect the battery
pack.

If the notebook is to be stored for more than two weeks, we
suggest that you remove the battery pack. In suspend mode or
power-off condition, the battery power (from a fully-charged
battery pack) depletes in one month.

Battery Pack Characteristics

The battery pack has the following characteristics:

• Battery pack self-discharge Battery packs self-discharge slowly, which

may result in a low battery power condition after being stored for
weeks.

• Memory effect This is a phenomenon wherein charging finishes in

one-third the normal charge time. This leaves the battery pack not
fully charged. This situation can usually be improved by conditioning
the battery pack twice a month. Please refer to section 2.3.2 for details
on how to condition the battery pack.

2-2 User’s Manual

2.2 Charging 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 system uses rapid charging when the notebook (with a battery
pack installed) is turned off and a powered AC adapter is connected to
it. In rapid mode, a fully depleted NiMH battery gets fully charged in
approximately two hours.

• Charge-in-use mode

When the notebook is in use with the AC adapter, the notebook also
charges the battery pack if one is installed. In charge-in-use mode, a
fully depleted NiMH battery gets fully charged in approximately four
and a half to six hours.

• Trickle mode

When the battery is fully charged, the adapter changes to trickle mode
to maintain the battery charge level.

The battery indicator lights up when the battery is being charged and turns
off when it is fully-charged or when the battery is not being charged.

If the notebook emits five beeps and then turns off (after the
power-on self test), it means the battery pack does not have
enough charge. Use the AC adapter instead, or recharge the
battery pack.

Operating on Battery Power 2-3

2.3 Optimizing Battery Life

This section helps you get the most out of battery operation. Optimizing
battery life prolongs the charge/recharge cycle and improves recharge
efficiency.

2.3.1 Maximizing Battery Power

Follow these suggestions to maximize battery power:

• Purchase an extra battery pack

• Use the system utility ASTDK to reserve hard disk space for the zero-

volt suspend function.

• Condition the battery pack to reduce the possibility of memory effect.

Refer to section 2.3.2.

• Use the AC adapter whenever possible so that the battery is reserved

for on-the-go computing.

• Disable the parallel and serial ports if no devices are connected to

these ports. You can do this through Setup.

• Make use of the power-saving modes described in sections 2.4 and

2.5.

• Eject the PCMCIA card from the card slot when not in use, since the

PCMCIA card draws extra power

• When using a network card, logout first before ejecting the card.

• Use the disk cache utility SMARTDRV (bundled with MS-DOS) or

create a virtual disk (RAMDRIVE) to lessen the loading of the hard
disk.

• Store the battery pack in a cool, dry place. The recommended storage

temperature for battery packs ranges from 10°C to 30°C. The higher
the storage temperature, the faster the battery pack self-discharges.

2-4 User’s Manual

• The batteries can be recharged about 500 times when used as

directed. Excessive rapid recharging decreases battery life.

2.3.2 Conditioning the Battery Pack

Conditioning the battery pack reduces the possibility of memory effect. We
recommend that you condition the battery pack at least once every month,
preferably twice a month.

Follow these steps to condition the battery pack:

1. Disconnect the AC adapter.

2. Turn on the notebook (with the battery pack installed).

3. Press m (during POST) to enter Setup.

2.4 Power Management

This notebook has a built-in power management unit that monitors system
activity. System activity refers to any activity involving one or more of the
following devices: keyboard, mouse, diskette drive, hard disk drive,
peripherals connected to the serial and parallel ports, and video memory. If
no activity is detected for a specified period of time (called an inactivity
time-out), the system switches to one of the power-saving modes to
conserve energy. These power-saving modes are display standby mode,
fixed disk standby, and system standby/suspend mode.

The Setup utility allows you to specify the inactivity time-out.

2.4.1 Display Standby Mode

Screen activity is determined by the keyboard, the built-in touchpad, and an
external pointing device. If these devices are idle for the period specified
by the Display Standby Timer, the display shuts off until you press a key or
move the touchpad or external mouse.

We strongly recommend you to enable the Display Standby
Timer with a shorter time interval to prolong your battery life.

“Automatic Dim” Feature

The notebook has a unique “automatic dim” power saving feature. When
the notebook is using AC power and you disconnect the AC adapter from
the notebook, the system “decides” whether or not to automatically dim the
LCD backlight to save power.

2-6 User’s Manual

If the LCD backlight is too bright, the system automatically adjusts it to a
manageable level; otherwise, the level stays the same. If you want a
brighter picture, you can then adjust the brightness and contrast level using
hotkeys ( -m1).

If you reconnect AC power to the system, the system automatically adjusts
the LCD backlight to its original level — the brightness and contrast level
before disconnecting the AC adapter. If you adjusted the brightness and
contrast level after disconnecting AC power, the level stays the same after
you reconnect the AC adapter.

2.4.2 Fixed Disk Standby Mode

The hard disk drive enters the standby mode when there are no disk
read/write operations within the period of time specified by the Fixed Disk
Standby Timer. In the standby state, the power supplied to the hard disk
drive is reduced to a minimum. The hard disk drive returns to normal once
the system accesses it.

2.4.3 Suspend Mode

In suspend mode the system power shuts off. The notebook saves all
system information onto the hard disk before it enters suspend mode. The
notebook restores this information and resumes where you left off upon
leaving suspend mode.

A necessary condition for the notebook to enter suspend mode is that the
reserved space for saving system information on the hard disk must be
larger than the combined system and video memory size. Under such
conditions, the system standby/suspend button acts as the suspend button.
See Appendix D for information on the ASTDK utility.

If the notebook is connected to a LAN environment or has a

current modem connection, it does not resume connection

• Press the standby/suspend button ( )

If the notebook beeps but does not enter suspend mode after
pressing the standby/suspend button, it means the operating
system does not allow the notebook to enter the power saving
mode.

• Set a value for the System Standby/Suspend Timer in Setup. If the

waiting time specified by this time elapses without any system activity,
the system goes into suspend mode

• Enable the Suspend upon Battery-low parameter in Setup. If a battery-

low condition takes place, the notebook enters suspend mode in about
three minutes. See section 2.6.

• Invoked by the operating system power saving modes

When the notebook enters suspend mode, the whole system does not
consume any power.

To exit system suspend mode, press the power switch ( ).

Do not change any system devices when the notebook is in
suspend mode.

even after the notebook returns to normal operating mode.

2-8 User’s Manual

2.4.4 System Standby Mode

The notebook consumes very low power in system standby mode. Data
remain intact in the system memory.

The necessary condition for the notebook to enter system standby mode is
that the reserved disk space size for saving system and video memory is
insufficient so the notebook is unable to enter suspend mode.

In this situation, there are four ways to enter system standby mode:

• Press the standby/suspend button ( )

If the notebook beeps but does not enter system standby mode
after pressing the standby/suspend button, it means the
operating system does not allow the notebook to enter the
power saving mode.

• Set a value for the System Standby/Suspend Timer in Setup. If the

waiting time specified by this timer elapses without any system activity,
the notebook goes into system standby mode.

• Enable the Suspend upon Battery-low parameter in Setup. If a battery-

low condition takes place, the notebook enters system standby mode in
about three minutes. See section 2.6.

• Invoked by the operating system power saving modes

The following signals indicate that the notebook is in system standby mode:

• The buzzer beeps (when you press the standby/suspend button)

• The standby mode indicator ( ) flashes

Unstored data is lost when you turn off the notebook power in
system standby mode.

Operating on Battery Power 2-9

To leave system standby mode and return to normal mode, press the
standby/suspend button ( ). If an incoming modem event occurs, the
system returns to normal mode.

If the notebook is connected to a LAN environment or has a
current modem connection, it may not resume connection after
the notebook returns to normal operating mode.

2.5 Advanced Power Management (APM)

This notebook supports the APM standard designed to further reduce
system power consumption. APM is a power-management approach
defined jointly by Microsoft and Intel. An increasing number of software
supports APM to take advantage of power saving features and allows
greater system availability without degrading performance.

DOS

You can use the APM feature under the DOS environment by including the
POWER.EXE command in the CONFIG.SYS file. See the MS-DOS
manual for instructions on how to edit the CONFIG.SYS file. For more
information about APM, type the following at the DOS prompt:

HELP POWER.EXE e

Windows 3.x

To enable APM under the Windows environment, run Windows Setup and

Windows 95, the system time and date do not display the
correct settings after the notebook returns to normal
operation from system standby or suspend mode. To
update the time and date, reboot the notebook. Enable
APM to avoid this problem.

2. You can not change some power management parameter
in the Setup screen after APM is enabled because it is
controlled by APM.

Advanced Power Management greatly prolongs battery life.

2.6 Battery-low Warning

You never have to worry about battery power as long as you are using the
AC adapter. However, when you operate the notebook on battery power,
pay extra attention to the warning beeps and the power indicator. The
power indicator flashes when the battery power is low.

The following signals indicate a battery-low condition:

• The buzzer generates four short beeps every minute, if you enabled

the Battery-low Warning Beep parameter in Setup

• The power indicator flashes at regular intervals until battery power is

depleted

When you receive a battery-low warning, you have around three minutes1 to
save your work. If you do not connect the AC adapter within this period, the
notebook enters suspend mode if the Standby/Suspend upon Battery-low
parameter in Setup is enabled and the following conditions exist:

• There is enough battery power left to save system information onto the

hard disk.

• The reserved disk space for saving these data is larger than the

combined system and video memory size.

Otherwise, the notebook enters system standby mode.

Connect the AC adapter as soon as possible. Data is lost
when notebook power is cut off during system standby mode.
