1.3. Product Overview
The Extensa 67x Series follows the 65x Series. The Extensa 67x notebook series is similar in
construction and appearance, has similar operating controls and indicators and uses the same
software. It uses a similar startup self test program (described in detail in Chapter 5 of this manual).
There are differences at the board level which affect assembly/disassembly as described in Chapter
6 of this manual. There are also differences in Field-Replaceable Units (FRUs), particularly the
Printed Circuit Boards, so separate FRU lists and logic diagram sets are provided in the appendices.
Table 1-1 summarizes some of the major differences between the 67x Series and the 65x Series
Notebook Computers.

1-4 General Description
1.3.1 Video Display Features
The Extensa 67x Series Notebooks contain large screen internal LCD displays and can
simultaneously drive an external CRT (SimulSCANTM mode). On all Extensa models, the LCD
screen brightness, contrast, video mode of operation, etc. are adjustable from the keyboard as
described in Paragraph 1.2.2.3.

The Extensa 67x Series Notebooks are equipped with a 15-pin SVGA connector that can drive an
external CRT (either alone or simultaneously with the internal LCD).
When the notebook is set to the SimulSCAN mode, a minimum resolution of 800 x 600 x 256 colors
is supported. When operating in the External CRT Mode, resolutions up to 1280 x 1024 x 256 colors
are supported.
1.3.1.3 Display Hot Key Sequences
The display mode of operation (LCD only, Simultaneous LCD and external CRT and external CRT
only modes) is keyboard-selectable using the following hot key sequences.
• Fn-Up Arrow and Fn-Down Arrow - control LCD screen brightness (higher brightness setting
uses more battery energy)
• Fn-Right Arrow - lightens the LCD screen contrast
• Fn-Left Arrow - darkens the LCD screen contrast
• Fn-F12 - alternates between display modes (LCD, External CRT or both)
• Fn-F11 - turns off the LCD backlight; pressing any key turns the LCD backlight on.
Note: In addition to the hot keys that control the notebook display functions, there are several
other hot key functions that control other notebook functions such as turning the
Touchpad on/off, etc. For these sequences, refer to Chapter 3.
1.3.2 Software Features

1-8 General Description
1.4. Standard Test Features
The Extensa 67x Series Notebook Computers use modular design and built-in test features to
reduce the mean time to repair.
1.4.1 Power On Self Test
The Extensa line of notebook computers contain a BIOS-resident, Power On Self Test (POST) that
automatically performs a test of memory and all major circuits each time the computer is powered
up. In the event of a failure, the computer displays a descriptive error message and issues a series
of coded beeps (in case the display subsystem is not functioning). If self test completes normally,
the computer displays the amount of memory tested, loads the Operating System and Windows
environment.

Service Guide 2-1
2.3. Installing Internal Notebook Options
If you have no internal options to install at this time, skip to Paragraph 2.4. Otherwise, continue with
Paragraph 2.3.1.
2.3.1 Installing Main Memory Expansion (Optional)
Main memory on the 67x Series Notebooks can be expanded using EDO Small Outline Dual Inline
Memory Modules (EDO soDIMMs). These modules currently are available in 8 MB, 16 MB or 32 MB
sizes and install in expansion memory slots on the Main Board accessed through the Memory
Expansion Door on the bottom of the notebook. The installation process consists of the following
steps:
Caution: The EDO soDIMM module option contains components that are sensitive to static
electricity. When handling the module and the internal parts of the computer, protect
against static electricity by using wrist or ankle grounding straps and grounded working
mats. When moving or storing items, use the anti-static bags supplied with the items.
Figure 2-1 Memory Expansion Removal/Replacement
1. Ensure that the notebook is powered off and the AC adapter disconnected from the AC outlet.
Also, ensure that the battery is out of the unit.
2. Disconnect any peripheral device interface cables from the external interface connectors and
remove any installed PCMCIA options.
3. Turn the notebook over and locate the Expansion Memory Access Cover on the bottom of the
notebook.
4. Remove the screw holding the Expansion Memory Access Cover and remove the cover.
5. Remove the EDO soDIMM module from its shipping container.
6. Refer to Figure 2-1. To install an soDIMM module, first align the connector edge of the memory
module with the key in the connector. Insert the edge of the memory module board into the
connector using a rocking motion to fully insert the module. Push downward on each side of the
memory module until it snaps in place.
2-2 Installation
7. If installing a second soDIMM, repeat Step 6.
8. Reinstall the Expansion Memory Access Cover using the screw removed in Step 4.
9. Replace the Keyboard Assembly and any components previously removed. Replace the AC
adapter.
10. Power up the notebook and reboot. If all of the installed memory is not recognized, try
reseating the soDIMM module(s) and rebooting.
Note: After installing expansion memory in your notebook, you must run the PHDISK utility in
order for the Save-To-Disk or 0V Suspend functions to operate correctly.
2.3.2 Setting up the Software
After installing expansion memory, perform the following procedure:
1. Run PHDISK.
• In Windows 95
1. From the Taskbar, select Start, then Shut Down.
2. Select the "Restart the Computer in MS-DOS mode" option.
3. Click on Yes.
4. Type PHDISK/C/F at the DOS prompt.
• In Windows for Workgroups and Windows NT
1. Exit all applications and exit Windows to DOS.
2. At the DOS command prompt, type PHDISK/C/F. This will create a file which can be
used to save the contents of your memory system when you perform a 0V Suspend
operation
Service Guide 2-3
2.4. Installing External Options
2.4.1 Installing PCMCIA Options
The Notebook has two connector slots for PCMCIA option cards. These two slots can be used to
install one Type III or two Type I/II credit card size PCMCIA option cards. You can install a PCMCIA
(PC card) without turning the computer off.
Use the following procedure to install a PCMCIA option:
1. Review the installation instructions supplied with the PCMCIA option card(s).
2. Hold the card at the end opposite the connector pins with the label side up. Insert the card into
an unused slot on the left side of the Notebook.
3. If the option requires external cabling (e.g. Modem option), connect external cabling at this
time.
Note: After installation of a PCMCIA option card, Windows 95 displays the New Hardware Found
dialog box to help you configure the new device. To remove a card, click on the PCMCIA
icon; then, press the appropriate PC Card Release Button (or press both buttons for a
Type III device) and remove the option.

2.5. Installing External Notebook Options
2.5.1 Installing Ext. Keyboard/Mouse/Numeric Keypad
A PS/2 compatible keyboard, mouse or an optional PS/2-compatible numeric keypad may be
installed on the notebook via the mouse connector on the left rear port as shown in Figure 2-3.

Service Guide 2-5
2.5.2 Installing an External Parallel Printer or Floppy Drive
The Notebook is equipped with an external, bidirectional, ECC/EPP compatible, 25-pin parallel
printer port. The connector pinouts and connector location are shown in Figure 2-4. When used with
a special cable, an external floppy disk drive may also be attached to the notebook via the parallel
port. When a floppy disk drive is connected to the parallel port, the floppy disk drive in the Modular
Bay is disabled, if present.
