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.

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

Click once.

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.

System Utilities

BIOS Setup Utility

The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/ Output System).

Y our computer is already properly configured and optimized, and you do not need to run this utility . However, if you encounter configuration problems, you may need to run Setup. Please also refer to Chapter 4 Troubleshooting when problem arises.

To activate the BIOS Utility, press F2 during POST (when “Press <F2> to enter Setup” message is prompted on the bottom of screen).

The default parameter of F12 Boot Menu is set to “disabled”. If you want to change boot device without entering BIOS Setup Utility, please set the parameter to “enabled”.

Press <F12> during POST to enter multi-boot menu. In this menu, user can change boot device without entering BIOS SETUP Utility.

Navigating the BIOS Utility

There are five menu options: Information, Main, Security, Boot, and Exit. Follow these instructions:

• To choose a menu, use the left and right arrow keys.

• To choose an item, use the up and down arrow keys.

• To change the value of a parameter, press F5 or F6.

• Press Esc to be prompted to exit the BIOS utility.

• In any menu, you can load default settings by pressing F9. You can also press F10 to save any changes made and exit the BIOS Setup Utility.

NOTE: You can change the value of a parameter if it is enclosed in square brackets. Navigation keys for a

particular menu are shown on the bottom of the screen. Help for parameters are found in the Item Specific Help part of the screen. Read this carefully when making changes to parameter values. Please note that system information is subject to different models.

• New features or options

• Restore a BIOS when it becomes corrupted.

Use the Flash 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 Flash utility. NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Flash. NOTE: Please use the AC adaptor power supply when you run the Flash 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. Follow the steps below to run the Flash.

To reset the HDD password, perform the following steps:

1. After the error is displayed, select the Enter Unlock Password option on th e screen.

2. An Encode key is generated for unlocking utilities. Note down this key.

3. Execute the UnlockHD.EXE file to create the unlock code in DOS Mode using the format UnlockHD

[Encode code] with the code noted in the previous step, as follows:

UnlockHD 76943488

4. The command generates a password which can be used for unlocking the HDD.

Password : 46548274

5. Key in the password from the previous step to unlock the HDD as shown.

Using Boot Sequence Selector

The Boot Sequence Selector allows the boot order to be changed without accessing the BIOS. To use Boot Sequence Selector, perform the following steps:

1. Enter into DOS.

2. Execute BS.exe to display the usage screen.

3. Select the desired boot sequence by entering the corresponding sequence. For example, enter BS 2 to

change the boot sequence to HDD | CD ROM | LAN | Floppy.

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 Verifying DMI poo l 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

Chapter 3 43

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 cables from th e system.

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

4. Remove the battery pack.

44 Chapter 3

Disassembly Process

IMPORTANT: The LCD Module cannot be disassembled outside of factory 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.
