Preface
Before using this information and the product it supports, please read the fol-
lowing general information! 
1  This Service Guide provides you with all technical information relating to 
the BASIC CONFIGURATION decided for Acers global product offering. 
To better fit local market requirements and enhance product competitive-
ness, your regional office MAY have decided to extend the functionality of 
a machine (e.g. 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 responsi-
ble 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 PROVID-
ERS, 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.

							2 System Specifications
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.
