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 TouchPad, 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.

Using the Keyboard

The keyboard has full-sized keys and an embedded numeric keypad, separate cursor, lock, Windows, 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.

BIOS Flash Utilities

The BIOS flash memory update is required for the following conditions:

• New versions of system programs

• New features or options

• Restore a BIOS when it becomes corrupted.

Use the Phlash utility to update the system BIOS flash ROM.

NOTE: If you do not have a crisis recovery diskette at hand, then you should create a Crisis Recovery

Diskette before you use the Phlash utility.
NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash.
NOTE: Please use the AC adaptor power supply when you run the Phlash utility. If the battery pack does not

contain enough power to finish BIOS flash, you may not boot the system because the BIOS is not

completely loaded.
Fellow the steps below to run the Phlash.

1. Prepare a bootable diskette.

2. Copy the flash utilities to the bootable diskette.

3. Then boot the system from the bootable diskette. The flash utility has auto-execution function.

Using DMITools

The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM to be used in the DMI
pool for hardware management.

When the BIOS displays Verifyin g DMI pool data it is checking that the table correlates with the hardware
before sending to the operating system (Windows, etc.).

To update the DMI Pool, perform the following steps:

1. Boot into DOS.

2. Execute dmitools. The following messages report to screen to confirm completion:

• dmitools /r ==> Read dmi string from bios

• dmitools /wm xxxx ==> Write manufacturer name to eeprom (max. 16 characters)

• dmitools /wp xxxx ==> Write product name to eeprom (max. 16 characters)

• dmitools /ws xxxx ==> Write serial number to eeprom (max. 22 characters)

• dmitools /wu xxxx ==> Write uuid to eeprom

• dmitools /wa xxxx ==> Write asset tag to eeprom (max. 32 characters)

The following examples show the commands and the corresponding output information.

Machine Disassembly and Replacement

IMPORTANT: The outside housing and color may vary from the mass produced model.

This chapter contains step-by-step procedures on how to disassemble the notebook computer for
maintenance and troubleshooting.

Disassembly Requirements

To disassemble the computer, you need the following tools:

• Wrist grounding strap and conductive mat for preventing electrostatic discharge

• Flat screwdriver

• Philips screwdriver

• Plastic flat screwdriver

• Plastic tweezers

NOTE: The screws for the different components vary in size. During the disassembly process, group the

screws with the corresponding components to avoid mismatch when putting back the components.

Chapter 3

46 Chapter 3

Pre-disassembly Instructions

Before proceeding with the disassembly procedure, make sure that you do the following:

1. Turn off the power to the system and all peripherals.

2. Unplug the AC adapter and all power and signal cab les from the system.

3. Place the system on a flat, stable surface.

4. Remove the battery pack.

Disassembly Process

IMPORTANT: The LCD Module cannot be disassembled outside of fa ctory conditions. If any part of the LCD
Module is faulty, such as the camera, antenna or LCD panel, the whole module must be replaced.

The disassembly process is divided into the following stages:

• External module disassembly

• Main unit disassembly

• LCD module disassembly

The flowcharts provided in the succeeding disassembly sections illustrate the entire disassembly sequence.
Observe the order of the sequence to avoid damage to any of the hardware components. For example, if you
want to remove the mainboard, you must first remove the keyboard, then disassemble the inside assembly
frame in that order.
