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.

To u c h p a d

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 efficiency.

Touch pa d B a s ics

Use the touchpad as follows:

T Move your finger across the touchpad to move the cursor.

T Press the left (1) and right (3) 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.

T Use the 4-way scroll (2) button to scroll a page up, down, left or right. This button mimics your

cursor pressing on the vertical and horizontal scroll bards of Windows applications.
