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.

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.

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.

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>

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.

Desired access Num Lock on Num Lock off

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.

If you key in the wrong HDD password three times, an error is generated.

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 key] 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.

Chapter 2 33

Removing BIOS Passwords:

To clear the User or Supervisor passwords, open the RAM door and use a metal instrument to short the U72
jumper as shown below.

Cleaning BIOS Passwords

To clean the User or Supervisor passwords, perform the following steps:

1. From a DOS prompt, execute clnpwd.exe

2. Press 1 or 2 to clean the desired password shown on the screen.

The onscreen message determines whether the function is successful or not.

Miscellaneous Utilities

Using Boot Sequence Selector

Boot Sequence Selector allows the boot order to be changes 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 BS2 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 Ve rifying DMI pool data it is checking the table correlates with the hardware before
sending to the operating system (Windows, etc.).

To update the DMI Pool, perform the following steps:

1. Enter into DOS.

2. Execute dmitools.exe. The following messages show dmitools usage:

DMITOOLS [ /R | /WP | /WS | /WU ] [ STRING ]

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

• dmitools /wm xxxx ==> Write manufacturer name to eeprom

• dmitools /wp xxxx ==> Write product name to eeprom

• dmitools /ws xxxx ==> Write serial number to eeprom

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

• dmitools /wa xxxx ==> Write asset tag to eeprom

IMPORTANT:The following write examples (2 to 5) require a system reboot to take effect

Chapter 2 35

Example 1: Read DMI Information from Memory

Input:

dmitools /r

Output:

Manufacturer (Type1, Offset04h): Acer
Product Name (Type1, Offset05h): Aspire one xxxxx
Serial Number (Type1, Offset07h): 01234567890123456789
UUID String (Type1, Offset08h): xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Asset Tag (Type3, Offset04h): Acer Asstag

Example 2: Write Product Name to EEPROM

Input:

dmitools /wp Acer

Example 3: Write Serial Number to EEPROM

Input:

dmitools /ws 01234567890123456789

Example 4: Write UUID to EEPROM (Create UUID from Intel WFM20.pdf)

Input:

dmitools /wu

Example 5: Write Asset Tag to EEPROM

Input:

dmitools /wa Acer Asstag

Using the LAN MAC Utility

Perform the following steps to write MAC information to eeprom:

1. Use a text editor, for example Notepad, to edit the MAC.CFG file as shown:

• WriteData= '0011 22334455' <------- MAC value

• StartAddr=7A <------- MAC address

• WriteLeng=6 <------- MAC value length

• KeepByte=0 <------- can be any value

2. Boot into DOS.

Machine Disassembly and Replacement

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

Disassembly Requirements

To disassemble the co mputer, 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.

Related Information

The product previews seen in the disassembly procedures may not represent the final product color or
configuration.

IMPORTANT: Cable paths and positioning may not represent the actual model. During the removal and
replacement of components, ensure all available cable channels and clips are used and that the cables are
replaced in the same position.

Chapter 3 39

General Information

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 the system.

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

4. Remove the battery pack.

Disassembly Process

The disassembly process is divided into the following sections:

• External components 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, and LCD Module then disassemble the
inside assembly frame in that order.
