1.
This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION

add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered
in this generic service guide. In such cases, please contact your regional offices or the responsible
personnel/channel to provide you with further technical details.
2.
Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information
available on your regional web or channel. If, 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.

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 24-bit true-color at
800x600 Super Video Graphic Array (SVGA) or 1024x768 eXtended Graphics Array (XGA) resolution.
Video performance
2X AGP video graphic accelerator with 8 MB of video memory 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. You can also 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 multi-display capability, allowing you to
extend your desktop to an external display device, such as an external monitor projector. With this feature
enabled, you can move program windows to/from the computer LCD and the external monitor.
The power management system incorporates an "automatic LCD dim" feature that automatically dims the LCD
when the computer is powered by a battery pack to conserve battery power. See “Power Management” on
page 26 for more information on power management features.
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.
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.

Fast Boot
Allows you to define your system’s booting process;
whether to skip some POST routines or proceed with
the normal booting process.
Boot Drive Sequence
Specifies the order in which the computer starts up
from. See the section below.
1st: Floppy Disk,
2nd: CD-ROM,
3rd: Hard Disk
4th: LANDesk (R) Service
Agent
Setting the Boot Drive Sequence
The Boot Drive Sequence section lists boot priorities (1st, 2nd, 3rd and 4th) for bootable drives in your
computer.
For example, the default value (1st:Floppy Disk, 2nd:CD-ROM, 3rd:Hard Disk and 4th:LANDesk (R) Service
Agent) tells the computer to first search for a bootable floppy disk in the floppy drive. If it finds one present, it
boots up from that floppy disk. If not, the computer continues to search for a bootable CD-ROM in the CD-
ROM drive. If it cannot boot up from the CD-ROM drive, it continues by booting up from the hard disk.
To set the boot drive sequence, use the cursor up/down keys to select a priority level (1st, 2nd, 3rd and 4th),
then use the cursor left/right keys to select the device for that priority level.

Three password types protect your computer from unauthorized access. Setting these passwords creates
several different levels of protection for your computer and data:
Setup Password prevents unauthorized entry to the BIOS Utility. Once set, you must key-in this
password to gain access to the BIOS Utility.
Power-On Password secures your computer against unauthorized use. Combine the use of this
password with password checkpoints on boot-up and resume from hibernation for maximum
security.
Hard Disk Password protects your data by preventing unauthorized access to your hard disk.
Even if the hard disk is removed from the computer and moved to another computer, it cannot be
accessed without the Hard Disk Password.
When a password is set, a password prompt appears on the left-hand corner of the display screen.
1. When the Setup Password is set, the following prompt appears when you press F2 to enter the BIOS
Utility at boot-up.
Type the Setup Password and press Enter to access the BIOS Utility.
2. When the Power-on Password is set, the following prompt appears at boot-up.
Type the Power-on Password (a symbol appears for each character you type) and press Enter to use the
computer. If you enter the password incorrectly, an x symbol appears. Try again and press Enter.
3. When the Hard Disk Password is set, the following prompt appears at boot-up.
