Display

The large graphics display offers excellent viewing, display quality and

desktop performance graphics. The computer supports a Thin-Film Transistor

(TFT) liquid crystal display (LCD) displaying 16-bit hi-color at 1024x768

Extended Graphics Array (XGA) resolution.

Video Performance

PCI local bus video with industry-leading 256-bit graphics acceleration and

high-speed 2.5MB Synchronous Graphics Random Access Memory

(SGRAM) boost video performance.

Simultaneous Display

The computer’s large display and multimedia capabilities are great for giving

presentations. If you prefer, you can also connect an external monitor when

giving presentations. This computer supports simultaneous LCD and CRT

display. Simultaneous display allows you to control the presentation from

your computer and at the same time face your audience. With the built-in S-

video output jack, you can even connect other output display devices such as

LCD projection panels for large-audience presentations.

Dual Display

The computer’s unique graphics chip takes advantage of Windows 98’s multi-

display capability, allowing you to extend your desktop to an external display

device, such as an external monitor or projector. With this feature enabled,

you can move program windows to/from the computer LCD and the external

monitor.

Power Management

The power management system incorporates an "automatic LCD dim"

feature that automatically decides the best settings for your display and at the

same time conserves power.

Chapter 1 3

Opening and Closing the Display

To open the display, slide the display cover latch to the left and lift up the

cover. Then tilt it to a comfortable viewing position. The computer employs a

microswitch that turns off the display (and enters standby mode) to conserve

power when you close the display cover, and turns it back on when you open

the display cover.

Note: If an external monitor is connected, the computer turns off the

display (but does not enter standby mode) when you close the

display cover.

To close the display cover, fold it down gently until the display cover latch

clicks into place.

Warning: To avoid damaging the display, do not slam it when you close

it. Also, do not place any object on top of the computer when

the display is closed.

Power Management

This computer 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, drive, hard disk, peripherals connected

to the serial and parallel ports, and video memory. If no activity is detected for

a period of time (called an inactivity time-out), the computer stops some or all

of these devices in order to conserve energy.

This computer employs a power management scheme that supports APM

(Advanced Power Management) or ACPI (Advanced Configuration and

Power Interface) which allows for maximum power conservation and

maximum performance at the same time.

If your computer is set for APM, you can set time-out values for your

computer’s devices before power-saving methods are applied to these

devices. If your computer is set for ACPI, Windows 98 handles all power-

saving chores for your computer.

Note: Power management (APM or ACPI) greatly prolongs your battery

life.

Power Management Modes

Display Standby Mode

Screen activity is determined by the keyboard, the built-in touchpad, and an

external PS/2 pointing device. If these devices are idle for the period

specified by the LCD backlight Time-out value, the display shuts off until you

press a key or move the touchpad or external mouse.

"Automatic Dim" Feature

The computer has a unique "automatic dim" power-saving feature. When the

computer is using AC power and you disconnect the AC adapter from the

computer, it automatically dims the LCD backlight to save power. If you

reconnect AC power to the computer, it automatically adjusts the LCD

backlight to a brighter level.

Hard Disk Standby Mode

The hard disk enters Standby mode when there are no disk read/write

operations within the period of time specified by the Hard Disk Time-out

value. In this state, the power supplied to the hard disk is reduced to a

minimum. The hard disk returns to normal once the computer accesses it.

720.book Page 27 Saturday, March 6, 1999 10:00 AM

28 System Specifications

Standby Mode

The computer consumes very low power in Standby mode. Data remain

intact in the system memory until the battery is drained.

There are four ways to enter Standby mode:

Pressing the Standby hot key Fn-F3

Allowing the waiting time specified by the Standby Time-out value or the

operating system to elapse without any system activity

Closing the display cover

When the computer is about to enter Hibernation mode (e.g., during a

battery low condition), but the Hibernation file is invalid or not present

Note: If the computer beeps but does not enter Standby mode after

pressing the Standby hot key, it means the operating system will

not allow the computer to enter the power-saving mode.

The following signals indicate that the computer is in Standby mode:

The buzzer beeps

The Standby indicator lights

Warning: Unstored data is lost when you turn off the computer power in

Standby mode or when the battery is drained.

To leave Standby mode and return to normal mode:

Press any key

Move the active pointing device (internal or external, PS/2 or serial)

Have the resume timer set and let it be matched

Open the display cover

Experience an incoming PC card modem event

720.book Page 28 Saturday, March 6, 1999 10:00 AM

Chapter 1 29

Hibernation Mode

In Hibernation mode, all power shuts off (the computer does not consume

any power). The computer saves all system information onto the hard disk

before it enters Hibernation mode. Once you turn on the power, the computer

restores this information and resumes where you left off upon leaving

Hibernation mode.

There is one necessary condition for the computer to enter Hibernation

mode:

The Hibernation file created by PhDISK must be present and valid.

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

Pressing the Hibernation hot key Fn-F4

Allowing the waiting time specified by the S2D Time-out value to elapse

without any system activity

When a battery low condition occurs and the Battery Low Suspend

parameter in Setup is set to [ENABLED].

Invoked by the operating system power-saving modes

Note: If the computer beeps but does not enter Hibernation mode after

pressing the Hibernation hot key, it means the operating system

will not allow the computer to enter the power-saving mode.

To exit Hibernation mode, press the power switch. The computer also

resumes from Hibernation mode if the resume timer is set and matched. The

computer also resumes via the network if the Wake on LAN Access

parameter is enabled.

Warning: Do not change any devices (such as add memory or swap

hard disks) when the computer is in Hibernation mode.

Sleep Mode (ACPI)

If ACPI is installed, all power management functions are handled by the

Windows 98 operating system. In this set-up, you do not need to set time-out

values for devices before they enter a power-saving mode.

Sleep mode may be one of three computer power-saving modes: Standby,

Hibernation or power off. Windows 98 automatically determines which of

these modes to enter in.

To enter Sleep mode under ACPI:

Pressing the Sleep hot key Fn-F4

Allowing idle times for devices and the computer determined by

Windows 98 elapses

Exiting sleep mode depends on which power-saving mode the computer is

currently in.

720.book Page 29 Saturday, March 6, 1999 10:00 AM

30 System Specifications

Advanced Power Management

This computer supports the APM standard designed to further reduce power

consumption. APM is a power-management approach defined jointly by

Microsoft and Intel. An increasing number of software packages support APM

to take advantage of its power-saving features and to allow greater system

availability without degrading performance.

For more information about APM under Windows 98, refer to your Windows

98 user’s manual.

Advanced Configuration and Power Interface

Advanced Configuration and Power Interface (ACPI) is a power management

specification jointly developed by Intel, Microsoft, and Toshiba. ACPI enables

Windows 98 to control the amount of power given to each device attached to

the computer. With ACPI, Windows 98 can turn off peripheral devices when

they are not in use, thereby saving power.

PhDISK

The PhDISK utility allows your computer to enter Hibernation mode. Before

entering Hibernation mode, your computer saves all necessary information

into a file or partition created by PhDISK, then shuts off power to all system

components. On the next start-up, the computer reloads the information from

the PhDISK file or partition and resumes from where you left off.

Note: By default, this utility program is automatically loaded and set up

on your computer, so you do not need to run it by yourself. You

only need to run this program if you upgrade your memory. You

can find PhDISK in the \windows\command\ directory.

Syntax

PHDISK [options]

where options:

/CREATE (/FILE or /PARTITION) creates the hibernation file or partition

/DELETE (/FILE or /PARTITION) deletes the hibernation file or partition

/INFO displays information on the hibernation file or partition

/REFORMAT PARTITION reformats the existing hibernation file or

partition

Caution: The Hibernation file is a hidden file named SAVE2DSK.BIN; DO

NOT delete or alter this file in any way except by using the

PhDISK utility. Improper deletion or alteration of this file could

cause you to lose all access to your computer.

check that power is supplied by the battery pack.

If you suspect a power problem, see the appropriate power supply checkout

in the following list:

“Checking the AC Adapter”

“Checking Operational Charging”

“Checking the Battery Pack”

Checking the AC Adapter:

If the power problem occurs only when the port replicator is used,

replace the port replicator.

If the power-on indicator does not turn on, check the power cord of the

AC Adapter for correct continuity and installation.

If the operational charge does not work, go to “Checking Operational

Charging.”

720.book Page 86 Saturday, March 6, 1999 10:00 AM

Chapter 4 87

Checking Operational Charging:

To check operational charging, use a discharged battery pack or a battery

pack that has less than 50% of the total power remaining when installed in

the computer.

Perform operational charging. If the battery status indicator does not turn on,

remove the battery pack and let it return to room temperature. Reinstall the

battery pack.

If the charge indicator still does not turn on, replace the battery pack. If the

charge indicator still does not turn on, replace the System board. Then

reinstall the battery pack. If the reinstalled battery pack is not charged, go to

the next section.

Checking the Battery Pack:

Battery charging will not start until the Fuel-Gauge shows that less than 95%

of the total power remains; with this condition the battery pack can charge to

100% of its capacity. This protects the battery pack from being overcharged

or having a shortened life.

Do the following:

1. Power off the computer.

2. Remove the battery pack and measure the voltage between battery

terminals 1 (+) and 7. See the following figure:

If the voltage is still less than +10.0 Vdc after recharging, replace the battery.

88 Troubleshooting

TouchPad Checkout

If the TouchPad does not work, check the configuration in the BIOS program.

If the configuration of the TouchPad is disabled, select Enable to enable it.

If this does not correct the TouchPad problem, continue with the following.

After you use the TouchPad, the pointer drifts on the screen for a short time.

This self-acting pointer movement can occur when a slight, steady pressure

is applied to the TouchPad pointer. This symptom is not a hardware problem.

No service actions are necessary if the pointer movement stops in a short

period of time.

If a click button problem or the pointing stick problem occurs, do the following:

1. Boot from the diagnostics diskette and start the PQA program (please

refer to “Running PQA Diagnostics Program”).

2. Go to the diagnostic Pointing Dev. in the test items.

3. Press F2 in the test items.

4. Follow the instructions in the message window.

If either the pointing stick or the click button do not work, do the following

actions one at a time to correct the problem do not replace a nondefective

FRU:

1. Reseat the TouchPad cables.

2. Replace the TouchPad cables.

3. Replace the TouchPad.

Symptom-to-FRU Index

The symptom-to-FRU index lists the symptoms and errors and their possible

causes. The most likely cause is listed first.

Note: Perform the FRU replacement or actions in the sequence shown

in the “FRU/Action” columns. If a FRU replacement did not solve

the problem, put the original part back in the computer. Do not

replace a nondefective FRU.

This index can also help you determine the next possible FRU to be replaced

when servicing a computer.

Numeric error codes show the errors detected in POST or system operation.

If no codes are available, use narrative symptoms.

If the symptom is not listed, go to “Undetermined Problems”.

Numeric Error Codes

The following is a list of the messages that the BIOS can display. Most of

them occur during POST. Some of them display information about a hardware

device, e.g., the amount of memory installed. Others may indicate a problem

with a device, such as the way it has been configured. Following the list are

explanations of the messages and remedies for the reported problems.

Note: If the system fails after you make changes in the Setup menus,

reset the computer, enter Setup and install Setup defaults or

correct the error.

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons

that have nothing to do with a hardware defect, such as: cosmic radiation,

electrostatic discharge, or software errors. FRU replacement should be

considered only when a recurring problem exists.

When analyzing an intermittent problem, do the following:

1. Run the advanced diagnostic test for the System board in loop mode at

least 10 times.

2. If no error is detected, do not replace any FRU.

3. If any error is detected, replace the FRU shown by the FRU code. Rerun

the test to verify that no more errors exist.

720.book Page 95 Saturday, March 6, 1999 10:00 AM

96 Troubleshooting

Undetermined Problems

You are here because the diagnostic tests did not identify which adapter or

device failed, installed devices are incorrect, a short circuit is suspected, or

the system is inoperative. Follow these procedures to isolate the failing FRU

(do not isolate a nondefective FRU).

Note: Verify that all attached devices are supported by the computer.

Note: Verify that the power supply being used at the time of the failure is

operating correctly (See “Power Systems Checkout”).:

1. Power off the computer.

2. Visually check them for damage. If any problems are found, replace the

FRU.

3. Remove or disconnect all of the following devices:

a. Non-Acer devices

b. Devices attached to the port replicator

c. Printer, mouse, and other external devices

d. Battery pack

e. Hard disk drive

f. DIMM

g. CD-ROM

h. Diskette drive

i. PC Cards

4. Power on the computer.

5. Determine if the problem has changed.

6. If the problem does not recur, reconnect the removed devices one at a

time until you find the failing FRU.

7. If the problem remains, replace each following FRU one at a time. Do not

replace a nondefective FRU:

a. System board

b. LCD assembly

c. CPU card

Utility Program Diskette

Setting LCD Panel ID

There is an EEPROM in the inverter which stores its supported LCD type ID

code. If you replace an LCD with one of a different brand or use a new

inverter, the ID information in the inverter EEPROM should be updated.

Follow the steps below to see the LCD Panel ID:

1. Follow the instructions on-screen to read current or to set new LCD Panel

ID code.

Note: When you set a new LCD Panel ID and the new LCD is not yet

enabled (to function), connect an external CRT to see the

program execution process.

Note: Make sure the new ID code you choose corresponds with the LCD

brand and type. If you write a wrong ID into the inverter, just

reboot and re-execute the program and input the correct ID code.

2. Restart the computer - the new LCD should work normally.

Note: If LCD cannot display after changing the ID code, make sure you

write the correct ID code, or try reseating the LCD FPC cable

connectors.

Setting Thermal Sensor Utility

The system is equipped with sensors to protect against system overheating.

By setting System and processor thermal thresholds, the system can turn on

the cooling fan or shut down automatically when temperatures reach the

defined threshold parameters.
