Preface
Before using this information and the product it supports, please read the following general information.
1.This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION

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.

Touchpad
The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor
responds as you move your finger on the surface of the touchpad. The central location on the palmrest
provides optimum comfort and support.
Touchpad Basics
The following items teach you how to use the touchpad:
TMove your finger across the touchpad to move the cursor.
TPress the left and right buttons located on the edge of the touchpad to do selection and execution
functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the
touchpad produces similar results.

NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The
touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response.
Tapping harder will not increase the touchpad’s responsiveness.
