1.1 Introduction

General Description

This manual contains field and factory level servicing information for the Extensa and 65x Series Notebook Computers manufactured for Texas Instruments. The first six sections contain information common to all members of the Extensa 60x/65x Family of Notebook Computers (any differences are described); the appendices contain model dependent maintenance information.

This section provides a general overview of the Extensa 60x/65x Series, describes the standard and optional features, and identifies the major assemblies and subassemblies. This section also contains detailed functional and environmental specifications for the Extensa 60x/65x Series Notebook Computers.

General Description 1-1

1.2 Product Overview

The Extensa Series contains two major product lines including:

♦ 60x Series

♦ 65x Series

Both notebook series are similar in construction and appearance, have similar operating controls and indicators and use the same software. Both notebook series use a similar startup self test program and diagnostics program (described in detail in Section 5 of this manual). There are differences at the board level which affect assembly/ disassembly as described in Section 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 60x Series and the 65x Series Notebook Computers.

1.3 Standard Test Features

PCMCIA Release Buttons

The Extensa 60x and 65x Series Notebook Computers use modular design and builtin test features to reduce the mean time to repair. A power on self test program automatically verifies the operational state of the primary circuits and a powerful suite of diagnostic tests (known as PC-Doctor) are available to further test selected parts of the system.

1.3.1 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.

1.3.2 PC-Doctor Diagnostics Program

The Extensa 60x and 65x 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 noninteractive 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 (by pressing F2) or saved in a disk file (by pressing F3).

General Description 1-13

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 the Troubleshooting Section (Section 5) for additional information regarding the Diagnostics Program.

1.4 International Product Models

The Extensa 60x and 65x Series Notebooks are available in various international configurations as listed in Table 1-7. The Models 600, 600CD, and 650CDT Dual Load systems are also available with localized software.

4.2.1 System Processor

The System Processor function for the notebook is implemented on the Motherboard 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.

4-2 Theory of Operation

4.2.2 Memory Subsystem

The memory subsystem comprises the following components:

♦ Main memory ♦ L2 Secondary Memory (cache) ♦ Flash ROM

The Extensa Series uses fast Extended Data Out (EDO) DRAM for main and video memory and high-speed synchronous, pipelined burst SRAM for L2 cache memory. Main BIOS and Video BIOS are stored in Flash ROM.

4.2.2.1 Main Memory

The standard 60x Series notebook comes with 8 MB of Main memory installed on the attached soDIMM. Memory expansion accommodations are provided via a standard soDIMM connector on the bottom of the Motherboard Assembly.

The 65x Series Notebooks come standard with 16 MB main memory, expandable to 80 MB.

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 32-bit high speed system.

4.2.3 Video Subsystem

The video subsystem is implemented on the VGA Video Board and on the Motherboard Assemblies.

The notebook contains a built-in 10.4 inch (or larger) LCD and features simultaneous LCD and external VGA display.

The video subsystem includes a 1 MB (60x Series) or 2 MB (65x Series) DRAM memory, 32-bit DRAM bus, and separate display and memory clocks. An additional frame buffer/ accelerator DRAM increases the available memory band width for CPU accesses. The

Theory of Operation 4-3

video section also uses additional levels of write FIFOs, a read cache, page mode DRAM.

4.2.4 Sound Subsystem

The Extensa Series Notebook is equipped with a sound chip set that is Sound Blaster and Sound Blaster Pro compatible. Internal stereo speakers provide the Notebook with sound generation capabilities. A set of 3.5 mm connectors allow for external microphone and line inputs and headphone/speaker outputs.

The sound subsystem also includes a variety of sound utilities that combine to provide additional multi-media functions:

4.2.5 Keyboard Subsystem

The keyboard subsystem, implemented on the Keyboard Assembly and the Motherboard Assemblies Board, consists of the following major sections:

♦ Keyboard Assembly ♦ Keyboard Scanner ♦ Status LED Interface

4.2.6 Hard Disk Drive Subsystem

The Hard Disk Drive Subsystem, implemented on the Motherboard Board and on the associated hard disk drive module(s), provides disk storage for all system software and user files.

The notebook is equipped with an 810 MB or larger hard disk drive. The hard disk drive also features built-in power conservation features configured from the standard CMOS Setup Routine. An Automatic Power Down mode can be selected which powers down the drive motor during periods of inactivity. An additional level of power conservation may also be selected which powers down the motor plus all control circuits.

The hard disk drives are factory formatted as a single drive (Drive C:) and are preloaded with installation versions of Windows 95 or Windows for Workgroups (in dual load versions, the user selects operating system during software installation).

4.2.6.1 Hard Disk Drive Power Management

Both the internal hard disk drive and the hard disk drive installed in the media bay

4-4 Theory of Operation

implement power savings features. From the CMOS setup routine, an automatic power down mode can be selected which enables the drive to turn off its motor after a specified period of inactivity. Additional Sleep modes can direct additional power savings during inactive periods by powering down the control circuitry.

4.2.7 Floppy Disk Drive Subsystem

The Extensa 60x and 65x Series notebooks contain provisions for supporting a Floppy Disk Drive installed internally or externally connected to the parallel port. The Floppy Disk Drive Subsystem consists of a Floppy Controller and the Floppy Disk Drive located either in the media bay or external to the notebook (not both).

The 3.5-inch floppy disk drive can read/write standard 3.5-inch disks (either1.44 MB or 2 MB capacity). The drive can also read a 720 KB disk (for interchange of data with other computers).

The data transfer rate for the floppy disk drive is 500 Kbits per second for high-density disks and 250 Kbits per second for double-density disks.

4.2.8 Power Subsystem

The notebook is equipped with a software/hardware monitored/controlled Power Subsystem that minimizes battery usage for prolonged battery operation and automatically recharges the batteries when the notebook is used with an AC adapter.

4.2.8.1 AC Power Adapter

The computer is equipped with a universal AC power adapter that converts AC voltage into DC voltage (approx. 46 Watts of power) used to operate the notebook and charge the batteries. The specifications for the AC adapter include:

♦ Input Voltage: 100 to 250 VAC ♦ Input Current: Approximately 1.5 Amps ♦ Input Frequency: 50 to 60 Hz

4.3.2.4 C&T 65550 High Perf ormance Flat Panel / CRT VGA Controller

The C&T65550 of high performance multimedia flat panel / CRT GUI accelerators extend CHIPS’ offering of high performance flat panel con tr ollers for full-featured note books and sub-notebooks. The C&T65550 offers 64-bit high performance and new hardware multimedia support features.

HIGH PERFORMANCE

Based on a totally new internal architecture, the C&T65550, integrates a powerful 64-bit graphics accelerator engine for Bit Block 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. The C&T65550 offers exceptional performance when combined with CHIPS advanced linear acceleration driver technology .

HARDWARE MULTIMEDIA SUPPORT

The C&T65550 implements independent multimedia capture (and display systems on-chip. The capture system places data in display memory (usually off screen) and the display system places it in a window on the s creen. 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 (c.g., from any size larger than 320x240 down to 352x248). 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 any where in display memory into an on-screen window which can be any size and located at any pixel boundary (YUV data is converted to RGB "on-the-fly" on out put). 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 inter polated to scale or zoom artifacts. Interlaced and non-interlaced data are supported in both capture and displa y systems.

VERSATILE PA NEL SUPPORT

The C&T65550 supports a wide variety of monochrome and color Single-Panel, Single-Dri ve (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 suppor ted. Up to 4096 different colors can be displayed on passive STN LCDs and up to 16M colors on 24-bit active matrix LCDs.

4-16 Theory of Operation

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, Th e C&T65550 controller's internal logic. memory interface, bus interface, and panel interfaces can he independently configu red to opera te at either 3.3 V or 5V.

SOFTWARE COMPATIBILITY/FL EXIBILITY

The C&T65550 are fully compatible with VGA at the register, and BIOS levels. CHIPS and third-party vendors supply fully VGA-compatible BIOS, end-user u t i l i t i es a nd drivers for common app l i cation programs Pin names in parentheses (...) indicate alternate functions.

4.3.2.5 TI 1130 PCMCIA Controller

The Tl PCI1130 is a high-performance PCI-to-PC Card controller that supports two independent PC Card sockets compliant with the 1995 PC card standard. The PCI1130 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 32bit PC Card, called CardBus, capable of full 32-bit data transfers at 33 MHz. Th e PCI1130 supports any combination of 16-bit and CardBus PC Cards in its two sockets, powered at 3.3 V or 5 V 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 PCI1130 internal data path logic allows the host to access 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.

A simplified block diagram of the PCMCIA Controller is shown in Figure 4-9.

Troubleshooting Procedures

5.1 Introduction

This section provides an overview of the fault isolation process, provides guidelines for isolating 60x/65x Series computer malfunctions to replaceable subassemblies and provides instructions for executing diagnostics and interpreting error messages.

5.2 Overview of Fault Isolation Process

The fault isolation process (summarized in Figure 5-1) consists of the following steps:

♦ Notebook power system (including battery packs and AC adapter

connections) - refer to Paragraph 5.4.

♦ Switch settings (ensure Power is On) ♦ Press the Shift key to ensure that Notebook is not in Suspend mode ♦ Verify if computer is configured to boot from the A: Drive or C: Drive.

♦ Check LCD brightness adjustment (press Fn-Up Arrow keys to increase

brightness)

♦ Ensure that computer is not set for external monitor (press Fn-F12 to select

internal screen)

♦ Record and attempt to resolve any displayed error messages or error beeps

(refer to Paragraph 5.2.3.1 and Tables 5-1 and 5-2)

♦ Try rebooting the system (Ctrl-Alt-Del) ♦ If the computer is capable of running the Setup program; check the serial

and parallel port configurations, Sound System enable/disable, and other features that may affect system operation.

♦ Run PC-Doctor Diagnostics to further isolate problem area (refer to

Paragraph 5.4). For indicated hardware failures, cycle power and repeat self test to verify that a hard failure has occurred.

♦ Remove and replace suspect hardware (as described in Section 6 of this

manual) and retest the system using the diagnostic tests as described in Paragraph 5.4.5.

5-2 Troubleshooting Procedures

5.3 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 for further instructions.

5.3.1 Troubleshooting a Power Supply Problem

If the computer does not power up when the Power Switch is set to the ON position, 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 ok, try replacing the AC adapter.

♦ Check to see that the battery packs are installed correctly and that the

battery charge indicators on the front of the battery packs indicate the batteries are charged (try using a new battery pack if batteries are discharged).

♦ If the AC outlet voltage, AC adapter, and battery packs test normal but the

computer will not power up, try disconnecting the display cable from the base (refer to Section 6 for disassembly instructions) to see if a short in the display assembly has occurred.

♦ If the display assembly appears to be normal, replace the Bottom Board as

described in Section 6 and retest system.

5.3.2 Troubleshooting a Display Problem

If the LCD remains blank when you turn on the computer, and the status indicators

Troubleshooting Procedures 5-3

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.

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.
