Using the Keyboard

The Acer Aspire D255 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>

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.

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).

Press F2 to enter setup. 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.

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 Verifying 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 41

Example 1: Read DMI Information from Memory

Input:

dmitools /r

Output:

Machine Disassembly and Replacement

IMPORTANT:The outside housing and color ma y vary from the mass produce d 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 45

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.

Disassembly Process

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.
