Remove HDD/BIOS Password Utilities
This section provides you with details about removing HDD/BIOS password:
Remove HDD Password:
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 the 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.

Removing BIOS Passwords:
To clear the User or Supervisor passwords, open the RAM door and use a metal instrument to short the J1 
jumper.
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.

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 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 Verifying 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.
Read DMI Information from Memory
Input: 
dmitools /r
Output:
Manufacturer (Type1, Offset04h): Acer
Product Name (Type1, Offset05h): TravelMate xxxxx
Serial Number (Type1, Offset07h): 01234567890123456789
UUID String (Type1, Offset08h): xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Asset Tag (Type3, Offset04h): Acet Asstag
Write Product Name to EEPROM
Input:
dmitools /wp Acer
Write Serial Number to EEPROM
Input:
dmitools /ws 01234567890123456789
4 ). Write UUID to EEPROM ( Create UUID from Intel WFM20.pdf )
Input:
dmitools /wu
5). Write Asset Tag to EEPROM
Input:
dmitools /wa Acet Asstag
NOTE: When using any of the Write options, restart the system to make the new DMI data effective.

Using the LAN MAC EEPROM Utility
You can use the MAC.BAT utility to write the MAC.CFG file to the EEPROM under DOS mode.
1.Use a text editor (for example: Notepad) to open the MAC.CFG file. You can see the MAC.CFG contents 
as below:
2.In DOS mode, run the MAC.BAT file to write MAC values to eeprom. WriteData = ‘001122334455 MAC value
StartAddr=7A MAC address
WriteLeng=6 MAC value length
KeepByte=0 don’t care

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.

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
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.

IMPORTANT: The outside housing and color may vary from the mass produced model.
External Modules Disassembly Flowchart
The flowchart below gives you a graphic representation of the external module disassembly sequence and 
instructs you on the components that need to be removed during servicing. For example, if you want to remove 
the keyboard, you must first remove the switch board.
