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.

2.7 Initial Software Load After unpacking and setting up the notebook for the first time, you must perform an initial software load that takes approximately 30 minutes.

Because of the way Windows 95 structures its files, stopping in the middle of the setup process can cause irreversible file damage.

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.

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).

Reducing screen brightness — Reduce screen brightness by pressing Fn+↓.

Connecting the AC adapter — If you have access to AC power, connect the computer to the AC adapter. You can do this without turning off the computer.

Suspending operations — Press Fn+F3 or Fn+F4 to put the computer into Suspend or Standby mode whenever you are not actively using the computer.

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.

The IRQ assignments for the 900 Series Notebooks is provided in Table 4-1.

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.

4.2.4 Video Subsystem The video subsystem is implemented on the VGA Video Board and on the Main Board Assemblies.

The notebook contains a built-in LCD and features simultaneous LCD and external VGA display.

The video subsystem includes a 1.5 MB 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 video section also uses additional levels of write FIFOs, a read cache, page mode DRAM. Control of the video subsystem is provided by the C&T 65550 High Performance Flat Panel/CRT VGA Controller chip. The C&T65550 multimedia flat panel/CRT GUI accelerators provide 64-bit high performance and new hardware multimedia support features as described in the following paragraphs.

4.2.4.1 C&T 65550 Features 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.

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 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 utilities and drivers for common application programs.

4.2.5

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.

The floppy drive controller is implemented on the PC87338 Super I/O Controller chip described in the previous paragraphs.

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

5 Troubleshooting Procedures 5.1 Introduction This section provides an overview of the fault isolation process, provides guidelines for isolating 900 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:

♦ Checking the Notebook power system (including battery packs and AC adapter connections) - refer to Paragraph 5.4.

♦ Checking Switch settings (ensuring Power is On and notebook correctly configured) - Pressing the Shift key to ensure that Notebook is not in Suspend mode - Verifying if computer is configured to boot from the A: Drive or C: Drive - Checking LCD brightness adjustment (press Fn-Up Arrow keys to increase brightness) - Ensuring that computer is not set for external monitor (press Fn-F12 to select internal screen)

♦ Undocking from the Mobile Productivity Base (if installed) and running diagnostics to isolate problem to either the base or the notebook.

♦ Recording and attempting to resolve any displayed error messages or error beeps (refer to Paragraph 5.3.3.1 and Tables 5-1 and 5-2)

♦ Rebooting the system (Ctrl-Alt-Del) ♦ If the computer is capable of running the Setup program; checking the serial and parallel port configurations, Sound System enable/disable, and other features that may affect system operation.

♦ Running PC-Doctor Diagnostics to further isolate problem area (refer to Paragraph 5.5). For indicated hardware failures, cycling power and repeating self test to verify that a hard failure has occurred.

♦ Removing and replacing 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 5.3.3.1 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.

Note: Refer to Appendix C for POST BIOS listing.

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.
