1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION
decided for Acer's "global" product offering. To better fit local market requirements and enhance product
competitiveness, 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 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 Basics

The following items show you how to use the TouchPad:
Move your finger across the TouchPad (1) to move the cursor.
Press the left (2) and right (3) buttons located beneath the TouchPad to perform selection and
execution functions. These two buttons are similar to the left and right buttons on a mouse.
Tapping on the TouchPad is the same as clicking the left button.
NOTE: When using the T ouchPad, keep it - and your fingers - dry and clean. The TouchPad is sensitive to
finger movement; hence, the lighter the touch, the better the response. Tapping too hard will not
increase the TouchPad’s responsiveness.
Function Left Button (2) Right Button (3) Main TouchPad (1)
Execute Quickly click twice. Tap twice (at the same speed
as double-clicking a mouse
button).
Select Click once. Tap once.
Drag Click and hold, then use

Tap twice (at the same speed
as double-clicking a mouse
button); rest your finger on
the TouchPad on the second

Using the Keyboard

Your NAV50 has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock,
function and special keys.

Lock Keys and embedded numeric keypad

The keyboard has three lock keys which you can toggle on and off.
The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters
located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols
are not printed on the keys.
Lock key Description
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock
<Fn> + <F11>
When Num Lock is on, the embedded keypad is in numeric mode. The keys
function as a calculator (complete with the arithmetic operators +, -, *, and /). Use
this mode when you need to do a lot of numeric data entry. A better solution
would be to connect an external keypad.
Scroll Lock <Fn> +
<F12>
When Scroll Lock is on, the screen moves one line up or down when you press
the up or down arrow keys respectively. Scroll Lock does not work with some
applications.
Desired access Num Lock on Num Lock off
Number keys on
embedded keypad
Type numbers in a normal manner.
Cursor-control keys on
embedded keypad
Hold <Shift> while using cursor-
control keys.
Hold <Fn> while using cursor-
control keys.
Main keyboard keys Hold <Fn> while typing letters on
embedded keypad.
Type the letters in a normal
manner.
