System Utilities
Most systems are already configured by the manufacturer or the dealer. There is no need to run
Setup when starting the computer unless you get a Run Setup message.
The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM.
This memory area is not part of the system RAM.
NOTE: If you repeatedly receive Run Setup messages, the battery may be bad/flat. In this case, the system
cannot retain configuration values in CMOS.
Before you run Setup, make sure that you have saved all open files. The system reboots immediately
after you exit Setup.

The S.M.A.R.T (Self-Monitoring, Analysis, and Reporting
Technology) system is a diagnostics technology that monitors
and predicts device performance. S.M.A.R.T software resides
on both the disk drive and the host computer.
The disk drive software monitors the internal performance of
the motors, media, heads, and electronics of the drive. The
host software monitors the overall reliability status of the
drive. If a device failure is predicated, the host software,
through the Client WORKS S.M.A.R.Tapplet, warns the user
of the impending condition and advise appropriate action to
protect the data.
This function, when enabled allows VGA BIOS to be copied to
the system DRAM for enhanced performance.

Switch Function
This option enables you to specify the function of
the button:
1. Disabled: The button functions is disabled
2. Break/Wake: The button functions are same as
suspend button in APM mode. When the button is
depressed, the system enters a suspended state until
the button is again depressed to return the system to
normal operating status.
Mode Use IRQIf you want an incoming call on a modem to
automatically resume the system from a powersaving mode, use this item to specify the interrupt
request line (IRQ) that is used by the modem. You
might have to connect the fax/modem to the
mainboard Wake On Modem connector for this
feature to work.
Hot Key Function AsThis option allows you to set the Hot Key
functionality to one of the following states:
Disabled, Power Off and Suspend
HDD Power DownThis option lets you specify the IDE HDD idle time
before the device enters the power down state. This
item is independent from the power states previously
described in this section (Standby and Suspend).
Soft-off by PWR-BTTNThis is a specification of ACPI and supported by
hardware. When Delay 4 sec. is selected, the soft
power switch on the front panel can be used to
control power On, Suspend and Off.The other setting
is Instant-Off, where the soft power switch is only
used to control On and Off, there is no need to press
4 sec, and there is no Suspend.
After AC Power LoseThis item specifies when your system reboot after a
power failure or interrupt occurs.
PM Wake Up EventsDisabled: The specified event's activity will not affect
the PM Timers/wake up the system.
Enabled: The specified event's activity will affect the
PM Timers/wake up the system.
For example, if you have a modem on IRQ3, you can
turn On IRQ3 as a wake-up event, so an interrupt
from the modem can wake up the system. Or you
may wish to turn Off IRQ12 (the PS/2) mouse as a
wake-up event, so accidentally brushing the mouse
does not awaken the system.

Power-On Self-Test (POST)
Each time you turn on the system, the Power-on Self Test (POST) is initiated. Several items are tested during
POST, but is for the most part transparent to the user.
The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the
system components, and controls the operation of the power-on password option. If POST discovers errors in
system operations at power-on, it displays error messages on screen, generates a check point code at port
80h or even halts the system if the error is fatal.
The main components on the main board that must be diagnosed and/or initialized by POST to ensure system
functionality are as follows:
TMicroprocessor with built-in numeric co-processor and cache memory subsystem
TDirect Memory Access (DMA) controller
TInterrupt system
TThree programmable timers
TROM subsystem
TRAM subsystem
TRTC RAM subsystem and real time clock/calendar with battery backup
TOnboard serial interface controller
TOnboard parallel interface controller
TEmbedded hard disk interface and one diskette drive interface
TKeyboard and auxiliary device controllers

T PS/2-compatible mouse port
T PS/2-compatible keyboard port
TSerial ports
TParallel ports
TUSB port

POST Check Points
When POST executes a task, it uses a series of preset numbers called check point to be latched at port 80h,
indicating the stages it is currently running. This latch can be read and shown on a debug board.
The following table describes the Acer common tasks carried out by POST. A unique check point number
represents each task.

POST Error Messages List
If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error
Messages List” to diagnose system problems. If you did not receive any error message, look for a description
of your error symptoms in “Error Sympton List”.
NOTE: When you have deemed it necessary to replace an FRU, and have done so, you must run a total
system check to ensure that no other activity has been affected by the change. This system check can
be done through the diagnostics program.
NOTE: Check all power supply voltages, switch, and jumper settings before you replace the main board. Also
check the power supply voltages if you have a “system no-power” condition.
NOTE: To diagnose a problem, first find the BIOS error messages in the left column. If directed to a check
procedure, replace the FRU indicated in the check procedure. If no check procedure is indicated, the
first Action/FRU listed in right column is the most likely cause.
