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
1-12 General Description
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.
1.4.2 PC-Doctor Diagnostics Program
The Extensa 900 Series Notebooks are shipped with PC-Doctor for Windows, a powerful
diagnostics tool that can help you scan a system for viruses, determine the hardware
configuration of a local or remote system, benchmark its performance, analyze the
performance of all subsystems, and perform a suite of interactive and non-interactive
tests on attached devices (such as printers, VGA monitors, SCSI® devices, CD-ROM
drives). The test results are stored in a log which can be printed out (by pressing F2)
or saved in a disk file (by pressing F3).
Features of the diagnostic program are accessed through a series of pull-down menus
and basic keyboard keys (cursor keys to move highlighted pointer, Enter key to select
a highlighted feature, Esc key to cancel a function and move back one level.
PC-Doctor is typically user-friendly but if you don't understand a feature, contextsensitive help information is available at any time by pressing the F1 function key;
pressing the F1 function key twice accesses the online Technical Reference Manual for
PC-Doctor.
A powerful set of utilities within PC-Doctor (that can be run locally or remotely) simplify
the task of determining system configuration data, allocating and using system memory,
IRQ and DMA use, what device drivers are installed, what COM and LPT ports are
assigned and what ports are available, identifying partitioning data for fixed disk
drive(s), determining the VGA setup information, reading the software interrupts/
interrupt vectors, etc.
Note: Refer to Troubleshooting Procedures (Section 5) for additional information
regarding the Diagnostics Program.

2-14 Installation
Before starting the initial software load process, ensure that you have the following:
♦ Extensa 900 User’s Guide - Contains latest software installation instructions.
♦ AC Adapter/Access to AC power - Although the battery pack may have some
charge, it may be insufficient for the entire set up. Loss of power during setup
can cause irreversible file damage.
♦ Certificate of Authenticity - You will need to enter the number from your
Windows 95 Certificate of Authenticity during Windows 95 Setup. This
certificate is part of the Windows 95 documentation kit. You need this number
even if you are installing Windows for Workgroups.
♦ Language - During initial setup you choose the following:
- Language for Windows displays
- Language for keyboard installed
♦ Printer type - As part of the Windows setup, you are prompted to choose a
printer. Microsoft® includes the files for many different printers. If you cannot
find your printer in the list, you will need the floppy disk with the printer driver
provided by the printer manufacturer. If you do not want to install a printer at
this time, you can skip this part of the setup. Which operating system to load
♦ Operating System Type - During initial setup you must choose which
operating system to load, either Windows 95 or MS-DOS and Windows for
Workgroups (DOS+WFW). This choice is final. You will not be able to change the
operating system after installation is complete. For most users Windows 95 is
the better choice. You might want to load DOS+WFW under the following
circumstances.
- Your corporation or workgroup may have guidelines that require use of
DOS+WFW. Check with your manager to determine the policy at your
company.
- The software that controls your local area network may not be compatible
with Windows 95. Check with your network administrator to determine
whether Windows 95 is compatible.
- Although most software that is compatible with DOS+WFW is also
compatible with Windows 95, it is possible that the existing software you
are using will not run in Windows 95. If you have a critical software
application that you intend to copy to your new computer, check with
the manufacturer of the software to determine whether your application
is compatible with Windows 95.

more effective presentations or play the most advanced video games.
3.8 Battery Saving Tips
There are a number of actions you can take to reduce the rate at which your computer
depletes the battery. By taking some or all of these actions, you can substantially
increase the time you can operate on battery power before recharging the battery:
♦ Reducing screen brightness — Although the screen controller uses new
technology to increase brightness without increasing energy consumption, the
screen is still the largest single consumer of the battery charge. Reducing the
brightness to the lowest acceptable level increases battery life. To reduce the
brightness, press Fn+↓.
♦ Caching the hard disk drive -— By caching the hard disk drive, you can reduce
the length of time the hard disk drive is rotating and using energy. Both
Windows 95 and Windows for Workgroups use a disk-caching program by
default. As long as you have not disabled these programs, you can take
advantage of the battery savings.
3.8.1 Lowering Inactivity Timeouts
Inactivity timeouts turn off devices in the computer when you are not using them.
Lowering the inactivity timeouts shortens the period of time the computer waits before
turning off the device.
Operating Instructions 3-9
3.8.2 Suspending Operation While Idle
Although the computer goes into Suspend mode automatically after a defined period of
inactivity, you can reduce energy consumption even further by pressing either Fn+F3
(Suspend) or Fn+F4 (Standby) as soon as you no longer need the computer to be active.
♦ Pressing Fn+F4 (Standby) turns off the screen.
♦ Pressing Fn+F3 (Suspend) turns off the screen, stops the hard disk drive, and
reduces energy usage to the lowest level possible without turning off the
computer.
♦ Pressing the Shift key resumes activity after the notebook has been in either
the Suspend or Standby modes.
3.8.3 Responding to a Low Battery Condition
When you are operating the computer on battery power and the charge remaining is
down to between 10% and 20%, the battery-low indicator blinks and an audible alarm
sounds. When this happens you should take the following actions to conserve battery
power and reduce the possibility of data loss.
♦
♦
♦
♦
♦
Saving files — Save all open files frequently while the computer is in a
low-battery condition.
Turning off the alarm — Turn off the audible alarm by pressing Fn+End
(Mute).

4.2.1 System Processor
The System Processor function for the notebook is implemented on the Main Board in
the form of an Intel Pentium P54-C Superscalar 586 Processor Chip. The processor
operates in conjunction with RAM and ROM Memory and other control logic to process
software instructions (BIOS, DOS, Windows, and applications). The processor
communicates with the hard disk drive and the memory components using high speed
busses.
The Processor also interacts with other hardware logic to provide the power savings
features for the notebook. These features include controlling CPU clock speeds,
reducing clock speeds whenever possible, e.g., when performing floppy disk drive
accesses, powering down unused devices, etc. A detailed block diagram of the Extensa
900 Series Notebook is shown in Figure 4-2.

4.2.2.1 Main Memory
The standard 900 Series notebook comes with 16 MB of Main memory installed on the
Main Board. Memory expansion accommodations are provided via a standard soDIMM
connector on the bottom of the Main Board Assembly. By installing a 64 MB soDIMM
module, the basic memory size can be expanded to a maximum of 80 MB.
Theory of Operation 4-5
4.2.2.2 Flash ROM
All versions of the Extensa notebook family use a "Flash" ROM that contains both the
main system BIOS and the VGA BIOS. The Flash ROM contains "Boot Block" logic that
allows downloading new versions of BIOS without destroying the Boot Load area.
The Flash ROM execution is 8 bits wide. However, better performance can be attained
by enabling the Shadow ROM in the CMOS setup routine or by selecting the Windows
Control Panel Applet. When the Shadow ROM is enabled, BIOS is copied into a 32-bit,
high-speed system.
4.2.3 System Controller Function
The Extensa 900 Series notebook design uses two chips, the ALI M1521 (memory, Cache
and DRAM Controller for the Pentium System and the M1523 (PCI to ISA Bridge chip)
combine to provide the 586 system controller function for the new multimedia/
multithreading operating system, Windows 95.
The notebook utilizes the BGA package to improve the AC characterization, resolves
system bottleneck and make the system manufacturing easier. The system architecture
includes the UMA, ECC, PBSRAM, SDRAM/BEDO, and multi-bus with highly efficient,
deep FIFO between the buses, such as the HOST/PCI/ISA dedicated IDE bus.
The I/O Address Map for the 900 Series Notebook is provided in Table 4-4.

Transfer (BitBLT), hardware cursor, and other functions intensively used in graphical
User Interfaces (GUls) such as Microsoft Windows. Superior performance is also
achieved through a direct 32-bit interface to the PCI Local Bus.
4.2.4.1.1 Hardware MultiMedia Support
The C&T65550 implements independent multimedia capture (and display systems) onchip. The capture system places data in display memory (usually off screen) and the
display system places it in a window on the screen.
The capture system can receive data from either the system bus or from the ZV enabled
video port in either RGB or YUV format. The input data can also scaled down before
storage in display memory (e.g., from any size larger than 320 x 240 down to
352 x 248). Capture of input data may also be double-buffered for smoothing and to
prevent image tearing.
The display system can independently place either RGB or YUV data from anywhere in
display memory into an on-screen window which can be any size and located at any
4-12 Theory of Operation
pixel boundary (YUV data is converted to RGB "on-the-fly" on output). Non-rectangular
windows are supported via color keying. The data can be functionally zoomed on output
up to 8x to fit the onscreen window and can be horizontally and vertically interpolated
to scale or zoom artifacts. Interlaced and non-interlaced data are supported in both
capture and display systems.
4.2.4.2 Versatile Panel Support
The C&T65550 supports a wide variety of monochrome and color Single-Panel,
Single-Drive (SS) and Dual-Panel, Dual Drive (DD) standard and high-resolution passive
STN and active matrix TFT/MIM LCD, and EL panels. For monochrome panels, up to
64 gray scales are supported. Up to 4096 different colors can be displayed on passive
STN LCDs and up to 16M colors on 24-bit active matrix LCDs. The C&T65550 offers a
variety of programmable features to optimize display quality. Vertical centering and
stretching are provided for handling modes with less than 480 lines on 480-line panels.
Horizontal and vertical stretching capabilities are also available for both text and
graphics modes for optimal display of VGA text and graphics modes on 800 x 600 and
1024 x 768 panels. Three selectable color-to-gray scale reduction techniques and
SMARTMAP© are available for improving the ability to view color applications on
monochrome panels. CHIPS®' polynomial FRC algorithm reduces panel flicker on a
wider range of panel types with a single setting for a particular panel type.
4.2.4.3 Low Power Consumption
The C&T65550 employs a variety of advanced power management features to reduce
power consumption of the display sub-system and extend battery life. Although
optimized for 3.3V operation, the C&T65550 controller's internal logic, memory
interface, bus interface, and panel interfaces can he independently configured to
operate at either 3.3V or 5V.
4.2.4.4 Software Compatibility/Flexibility

4.2.10 PCMCIA Subsystem
The notebook is equipped with a PCMCIA subsystem that accomodates either two
Type I or Type II PCMCIA cards or one Type III card. The heart of the PCMCIA Subsystem
is the TI PCI 1130 high-performance PCI-to-PC Card controller that supports two
independent PC Card sockets compliant with the 1995 PC card standard. The PCI 1130
provides a set of features that make it ideal for bridging between PCI and PC Cards in
both notebook and desktop computers. The 1995 PC Card standard retains the 16-bit
PC Card specification defined in PCMCIA release 2.1 and defines the new 32-bit PC
Card, called CardBus, capable of full 32-bit data transfers at 33 MHz. The PCI 1130
supports any combination of 16-bit and CardBus PC Cards in its two sockets, powered
at 3.3V or 5V as required.
The PCI 1130 is compliant with the PCI local bus specification revision 2.1, and its PCI
interface can act as either a PCI master device or a PCI slave device. The PCI bus
mastering is initiated during 16-bit PC Card DMA transfers or CardBus PC Card bus
mastering cycles.
All card signals are internally buffered to allow hot insertion and removal without
external buffering. The PCI 1130 internal data path logic allows the host to access
4-18 Theory of Operation
8-, 16-, and 32-bit cards using full 32-bit PCI cycles for maximum performance.
Independent 32-bit write buffers allow fast-posted writes to improve system-bus
utilization.
An advanced CMOS process is used to achieve low system-power consumption while
operating at PCI clock rates up to 33 MHz. Several low-power modes allow the host
power-management system to further reduce power consumption.

Troubleshooting Procedures
The built-in self test program and the disk resident diagnostics program (PC-Doctor)
are useful tools in computer troubleshooting. However, if the computer has a power,
keyboard or display problem, you must first solve this problem before running
diagnostics. If the computer powers up and displays messages on the LCD or emits a
series of beeps, skip to Paragraph 5.3.3.1 for further instructions.
5.3.1 Troubleshooting a Power Supply Problem
If the computer does not power up when the Power Switch is pressed, you most likely
have a malfunction in the power subsystem (loss of power at the AC outlet, faulty AC
adapter, discharged Battery Packs, or faulty Power Supply on the Main Board). With a
power problem, all LEDs are extinguished, the LCD screen is blank, the system does
not respond when the suspend switch is pressed several times consecutively and no
drive activity can be heard. The computer is unable to load software and displays no
visible signs of activity. To fault isolate a power problem, check the following:
♦ AC adapter and Battery - Plug in the AC adapter and double-check all
connections on the adapter and computer. Ensure that the Notebook Power
switch is set to the On position and that the system is not in Suspend or Sleep
mode.
♦ Measure the voltage at the AC outlet or plug in a known good appliance (e.g.,
a lamp) to verify that voltage is present. If the voltage is okay, try replacing the
AC adapter.
♦ Check to see that a charged battery pack is installed correctly; also attach the
AC adapter and connect to live wall outlet. If the AC outlet voltage, AC adapter,
and battery packs test normal but the computer will not power up, try the DCIn PWB, Power Supply PWB, Main Board PWB or LED PWB.
5.3.2 Troubleshooting a Display Problem
If the LCD remains blank when you turn on the computer, and the status indicators
light, check the following controls on the display:
♦ LCD suspend mode - Press Shift to terminate Suspend mode.
♦ Brightness set too low - Press Fn-Up Arrow keys to increase screen brightness
♦ Notebook Set for External Monitor - Press Fn-F12 to switch to the internal
screen.
♦ Faulty LCD - Replace the cover-display assembly as described in Section 6 of
this manual.
♦ Low battery - Use a fully charged battery and/or plug in the AC adapter.
Troubleshooting Procedures

Table 5-1 contains fault isolation information for Display Problems on the notebook.
Symptoms are listed along the left side of the chart and the various Display FRUs are
listed along the top of the chart. Within the body of the table are the probabilities of
each of the FRUs causing that particular problem. For example, a single display line
on the screen is most likely caused by the LCD Panel or Display Cable; other components
have a low probability of causing the problem.

5.3.3 Fault Isolation Using Power On Self Test
When the computer is first powered up, it automatically performs a Power On Self Test
(POST) that checks the notebook’s central hardware and memory functions. During
POST (which lasts for a few seconds), the display shows copyright and version number
information.
Note: Some procedures in this paragraph require you to use keystroke
sequences, such as Ctrl-Alt-Del. To execute a keystroke sequence such as this,
you must press all three keys simultaneously.
5-4 Troubleshooting Procedures
5.3.3.1 POST Error Messages
Upon successful completion of Power On Self Test, the computer automatically loads
its operating system and other built-in utilities. If POST fails to complete successfully,
the display shows one of the error messages described in Table 5-2.
Note: In the event of a hardware problem that affects the display, the Notebook
also communicates errors via a series of beeps. The interpretation of the beep
codes is provided in Table 5-3.

5.5 Fault Isolation Using Diagnostics
PC-Doctor, supplied with the Extensa Series Notebooks, is a powerful diagnostics tool
that can help you determine the hardware configuration of a local or remote system,
benchmark its performance, analyze the performance of all subsystems, and perform
a suite of interactive and non-interactive tests on attached devices (such as printers,
joystick devices, VGA monitors, SCSI® devices, CD-ROM drives). The test results are
stored in a log which can be printed out or saved in a disk file.
5.5.1 PC-Doctor (In DOS Mode or DOS Window)
Features of the diagnostic program are accessed through a series of pull-down menus
and basic keyboard keys (cursor keys to move highlighted pointer, Enter key to select
a highlighted feature, Esc key to cancel a function and move back one level.
PC-Doctor is typically user friendly but if you don't understand a feature, contextsensitive "help" information is available at any time by pressing the F1 function key;
pressing the F1 function key twice accesses the online Technical Reference Manual for
PC-Doctor.
A powerful set of utilities within PC-Doctor (that can be run locally or remotely) simplify
the task of determining system configuration data, allocating and using system memory,
IRQ and DMA use, what device drivers are installed, what COM and LPT ports are
assigned and what ports are available, identifying partitioning data for fixed disk
drive(s), determining the VGA setup information, reading the software interrupts/
interrupt vectors, etc.
Functionally, PC-Doctor includes the following:
♦ Group of non-Interactive diagnostic tests that perform a non-destructive test
of the major hardware functions in the notebook (Processor, Memory, System
board, video section, serial and parallel ports (when loopback adapters are
installed), hard disk drive and floppy disk drive).
♦ Group of Interactive tests (require operator input) for testing the keyboard, video
sections, sound subsystem, mouse, joystick, disk drive, printer subsystem and
the SCSI/CD-ROM Drive subsystems supported by the docking station options.
♦ Utility that provides detailed system information such as configuration data,
allocation and use of system memory, IRQ and DMA use, what device drivers
are installed, what COM and LPT ports are assigned and what ports are
available, partitioning data for fixed disk drive(s), VGA setup information,
software interrupts and interrupt vectors, and installed SCSI options.
♦ Group of special purpose utilities to run other tests from PC-Doctor, perform a
virus scan of the system, edit configuration files, surface scan hard drives,
measure system performance, open a DOS prompt, provides terminal access
to devices connected to serial ports, supports memory debug operations,
enables remote operations, permits deep discharge of notebook batteries and
provides an extensive test reporting function.
5-14 Troubleshooting Procedures
5.5.2 Supporting Online Documentation
The PC-Doctor Diagnostic contains the following online information sources:
♦ Online Technical Manual - Selected at any time by pressing F1 key twice or
by clicking on the Question Mark in the upper left hand corner of any
PC-Doctor Menu
♦ On-line Help system - Provides context sensitive information from every
PC-Doctor screen- accessed by pressing F1 key once (pressing F1 twice gets
you into the online manual)
5.5.3 User Interface to PC-Doctor
PC-Doctor is structured as a text-mode, windowed user interface with pull-down
menus. Program operation requires the use of the following keys:
♦ Cursor Keys - Moves the highlighted pointer
♦ Enter Key - Selects the highlighted option
♦ Esc Key - Cancels current function and goes back one step
♦ F1 Key - Activates the context-sensitive help feature (pressing F1 twice in a row
calls up the online Technical Reference Manual for PC-Doctor)
Scrolling windows, which show the results of various operations, use the following keys:
♦ Page Up/Page Down - Moves the screen one page at a time
♦ F2 - Prints the log to PRN
♦ F3 - Saves the log to a file
You can also use the mouse or Point to interact with PC-Doctor. The leftmost Select
key is used to choose objects (menu entries and action codes typically enclosed in
brackets). The rightmost Select key is equivalent to the Esc key which takes you back
to your previous step.
5.5.4 Quitting PC-Doctor
To exit PC-Doctor, select the Quit pull down menu and then select the Quit option.
Note: For additional information, access the Online Reference Manual for
PC-Doctor.
