Touchpad

The build-in touchpad is pointing device that senses movement on its surface. This means the cursor responds as you move your finger across the surface of the touchpad. The central location on the palmrest provides optimum comfort and support.

Touchpad Basics

Use the touchpad as follows:

T Move your finger across the touchpad (2) to move the cursor.

T Press the left (1) and right (4) 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 is the same as clicking the left button

T Use the 4-way scroll (3) button to scroll up or down and move left or right a page. This button

mimics your cursor pressing on the right scroll bar of windows applications.

Using the Keyboard

The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys and twelve function keys.

Lock Keys and embedded mumeric keypad

The keyboard has three lock keys which you can toggle on and off.

Lock Key Description

Caps Lock When Caps Lock is on, all alphabetic characters typed

are in uppercase.

Num lock <Fn>+<F11>

Scroll lock <Fn>+<F12>

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.

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.

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.
