for whatever reason, a part number change is made, it will not be noted in
the printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer office may have a DIFFERENT part number code to those
given in the FRU list of this printed Service Guide. You MUST use the list
provided by your regional Acer office to order FRU parts for repair and
service of customer machines.

720.book Page 2 Saturday, March 6, 1999 10:00 AM

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 Svideo 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 multidisplay 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.

System Specifications

720.book Page 3 Saturday, March 6, 1999 10:00 AM

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.

720.book Page 4 Saturday, March 6, 1999 10:00 AM

Indicators

The computer has six easy-to-read status indicators (LEDs) under the display
screen.

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

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 powersaving 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.

Chapter 1

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

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:

T
T
T
T

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:

T
T

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:

T
T
T
T
T

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

System Specifications

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

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:

T
T
T
T

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:

T
T

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.
Chapter 1

720.book Page 30 Saturday, March 6, 1999 10:00 AM

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.

To verify the symptom of the problem, power on the computer using each of
the following power sources:
1. Remove the battery pack and diskette drive.
2. Connect the AC Adapter and check that power is supplied.
3. Disconnect the AC Adapter and install the charged battery pack; then
check that power is supplied by the battery pack.

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.”

Troubleshooting

720.book Page 87 Saturday, March 6, 1999 10:00 AM

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.

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.

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 96 Saturday, March 6, 1999 10:00 AM

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.

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
