System Utilities
BIOS (Basic Input and Output System) includes a CMOS SETUP utility which allows user to
configure required setting or to active certain system features.
The CMOS SETUP saves the configuration in the CMOS SRAM of the mainboard. When the power is turned
off, the battery on the mainboard supplies the necessary power to the CMOS SRAM.
When the power is turned on, pushing the <Del> button during the BIOS POST (Power-On Self Test) will take
you to the CMOS SETUP screen. You can enter the BIOS setup screen by pressing “Ctrl+F1”. When setting
up BIOS for the first time, it is recommended that you save the current BIOS to a disk in the event that BIOS
needs to be reset to its original settings.
Q-Flash allows the user to quickly and easily update or backup BIOS without entering the operating system.
BIOS is a Window s-based utility that doesn’t required users to boot to DOS before upgrading BIOS but
directly download and update BIOS from the Internet.

Power-On Self-Test (POST)
Before the computer can be used, all the components must be tested and initialized, and the operating system
must be bootstrapped into memory. This process is know as the power-on Self test(POST), generally under
the control of the BIOS.
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. During POST, system
reports test or initialization failure through Beep codes, display error messages on screen(if available), or LED.
The system halts when fatal error occurs.
The main components on the main board that must be diagnosed and/or initialized by POST to ensure system
functionality are as follows:

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.

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.

FRU (Field Replaceable Unit) List
This chapter gives you the FRU (Field Replaceable Unit) listing in global configurations of
Aspire T680 / AcerPower FG. Refer to this chapter whenever ordering for parts to repair or for RMA
(Return Merchandise Authorization).
NOTE: Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information
available on your regional web or channel (http://aicsl.acer.com.tw/spl/, if you do not own a specific
account, you can still access the system with guest; guest). For whatever reasons 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 local FRU list provided by your regional Acer office to
order FRU parts for repair and service of customer machines.
