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.

4.2.1 System Processor

The System Processor function for the notebook is implemented on the Motherboard in the form of an Intel Pentium P55-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.

4.2.2 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 67x Series Notebooks come standard with 16 MB main memory, expandable to 80 MB. Memory expansion accommodations are provided via standard soDIMM connectors on the bottom of the Motherboard Assembly.

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 execution is 8 bits wide. However, better performance can be attained by enabling the Shadow ROM in the CMOS setup routine. When the Shadow ROM is enabled, BIOS is copied into 32-bit high speed memory system.

4.2.3 Video Subsystem

The video subsystem is implemented on the Motherboard Assemblies. The notebook contains a built-in 12.1 inch LCD and features simultaneous LCD and external VGA

display. The video subsystem includes a 2 MB DRAM memory, 32-bit DRAM bus, and separate display and

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, Windows NT or Windows for Workgroups.

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 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 67x 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

4.3.6 C&T 65550 High Performance Flat Panel / CRT VGA Controller

The C&T 65550 of high performance multimedia flat panel / CRT GUI accelerators extend CHIPS’ offering of high-performance flat panel controllers for full-featured notebooks and sub-notebooks. The C&T 65550 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 (GUIs) 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 displya 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 be scaled down before storage in display memory (e.g., from any size larger than 320x240 down to 352x248). Capture of input data may also be double buffered fro smoothing and to prevent image tearing.

The display system can independently place either RGB or YUV data from anywhere in display memory into an onscreen window which can be any size and located at any 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.

Versatile Panel Support

The C&T65550 supports a wide variety of monchrome 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 monchrome 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.

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, and panel interfaces can be independently configured to operate at either 3.3V or 5V.

Software Compatibility / Flexibility

The C&T65550 are fully compatible with VGA at the register, and BIOS levels. CHIPS and thirdparty vendors supply fully VGA-compatible BIOS, end-user utilites and drivers for common application programs.

The pin diagram is shown in Figure 4-7. Pin names in parentheses (…) indicate alternate functions.

4.3.7 TI1130 PCMCIA Controller

The TI 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 32-bit PC Card, called CardBUs, capable of full 32-bit data transfers at 33 MHz. The PCI1130 supports any combination of 16-bit and CardBus PC Cards in its two sockets, powered at 3.3V or 5V as required.

The PCI1130 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 allw 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

5.1. Introduction

This chapter provides an overview of the fault isolation process, provides guidelines for isolating 67x 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)

• 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.

• Remove and replace suspect hardware (as described in Chapter 6 of this manual) and retest

the system.

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 pressed ON, 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 Chapter 6 for disassembly instructions) then connect an external monitor to see if a short in the display assembly has occurred.

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 LCD panel as described in Chapter 6 of this manual.

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 Self Test

When the computer is first powered up, it automatically performs a self test of its central hardware and memory functions. During self test (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.

5.3.3.1 Self Test Error Messages

Upon successful completion of the self test, the computer automatically loads its operating system and other built-in utilities. If the self test 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.
