3.1 The Diagnostic Test 3.1 3 Test and Diagnostic Operation Handbook The Diagnostic Test This chapter explains how to use the Test & Diagnostic program (based on DAL00 T&D Version: 1.0) to test the functions of the computer’s hardware modules. The Test & Diagnostic Program is stored on the T&D diskettes. The program consists of a series of tests that run automatically when the Diagnostics Program items are selected and executed. NOTES: To start the diagnostics, follow these steps 1.
3 Test and Diagnostic Operation Handbook 3.1 The Diagnostic Test You will need the following equipment to perform some of the Diagnostic test programs.
3.2 Executing the Diagnostic Test 3.2 3 Test and Diagnostic Operation Handbook Executing the Diagnostic Test Toshiba MS-DOS is required to run the DIAGNOSTICS PROGRAM. To start the DIAGNOSTIC PROGRAM, follow these steps: 1. Insert the diagnostics diskette #1 in the floppy disk drive and turn on the computer. (The diagnostics diskette contains the MS-DOS boot files.) And then follow the instructions to swap with the diagnostics diskette #2 for T&D program installed in RAM.
3 Test and Diagnostic Operation Handbook 3.2 Executing the Diagnostic Test The display below will show up at the beginning of the T&D program.
3.2 Executing the Diagnostic Test 3 Test and Diagnostic Operation Handbook If an error is detected and a test fails, the following message displays: Press any key for the next action – the display below is presented if copying a test log file onto diskette is necessary. This action will be executed when “Y” key pressed. It will skip this process if “N” key pressed. NOTE: Press Pause to pause a test and Enter to resume.
3 Test and Diagnostic Operation Handbook 3.3 3.3 Executing the Diagnostic Test Executing the Diagnostic Test The config check test checks unit configuration. It includes: CPU type System memory size ODD type HDD type & capacity BIOS version This test needs input of a unit Part Number to make comparison with known SKU data. NOTE: To execute this test, you must input unit Part Number as “Uppercase Character”. It will show if its configuration is correct in green or incorrect in red.
3.4 DMI Check Test 3.4 3 Test and Diagnostic Operation Handbook DMI Check Test Checks if the computer’s Desktop Management Interface (DMI) is correct. DMI includes: Manufacturer Production Name Version Serial Number UUID OEM String It needs input of a unit Part Number before it shows this units DMI information and makes a comparison with SKU data. NOTE: To execute this test, you must input unit Part Number as “Uppercase Character”.
3 Test and Diagnostic Operation Handbook 3.5 3.5 PIO Loopback Test PIO Loopback Test The PIO loopback test will check below items through PIO loopback connector. External Interrupt External Loopback - including Pattern test, Data Pin test, Control register test & Control pin/ Status pin test. NOTE: Remember to connect a PIO loopback connector to the computer's printer port before test begins. The screen should display as below, indicating whether the test passed or failed when finished.
3.6 RTC Test 3.6 3 Test and Diagnostic Operation Handbook RTC Test Checks the computer’s RTC (Real Time Clock) and calendar functions by comparing the DOS and CMOS values. The test runs automatically. The screen should display as below, indicating whether the test passed or failed when finished.
3 Test and Diagnostic Operation Handbook 3.7 3.7 32-Bit for Sycard Test 32-Bit for Sycard Test Checks the computer’s 32-bit PC Card function. The test runs when the Sycard is inserted into a specific slot for test in sequence as shown below. NOTE: To execute this test, you must make sure the test connector of Sycard marked “CARDBUS”. There are two slots to be tested. A “beep” is generated during test for each slot.
3.8 Speaker Audio Test 3.8 3 Test and Diagnostic Operation Handbook Speaker Audio Test The speaker audio test allows the user to aurally confirm the speaker functions. It checks both speakers by sounding a three consecutive “beeps.” NOTE: Remember to turn up the volume to “Maximum” before this test starts. The screen should display as below, indicating whether the test passed or failed after the question.
3 Test and Diagnostic Operation Handbook 3.9 3.9 Fan ON/OFF Test Fan ON/OFF Test The fan test allows the user to aurally test whether the fan is working. Follow the procedures below: The computer will turn the fan be “ON” after any key is pressed. Listen to check whether the fan is working or not. NOTE: Remember to approach fan outlet that is near right side of unit whether fan is “ON”. The computer will stop the fan after any key pressed again.
3.10 Modem Test 3 Test and Diagnostic Operation Handbook 3.10 Modem Test The Modem test checks the function of dial tone detection. NOTE: Remember to plug phone line into the Modem connector of unit before this test starts. The test takes the Modem off-hook and checks for line current. Lack of line current is a failure, as the Codec needs line current to work in this mode – it means that there is no phone line connected, and the test will be aborted and showed “fail”.
3 Test and Diagnostic Operation Handbook 3.11 Main Battery Charge Test 3.11 Main Battery Charge Test NOTE: The AC adaptor (90W, 19V / 120W, 19V) for Sapporo X (DBL10) should be connected to successfully run this test.

Appendix A Appendix A Handling the LCD Module Precautions for handling the LCD module The LCD module can be easily damaged during assembly or disassembly. Therefore, please observe the following precautions when handling it: 1. When installing the LCD module in the LCD cover, be sure to seat it so that it is properly aligned and maximum visibility of the display is maintained. 2.
3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty, try breathing on the surface to create a light condensate and wipe it again. If the surface is very dirty, we recommend a CRT cleaning agent. Apply the agent to a cloth and then wipe the panel’s surface. Do not apply cleanser directly to the panel. CRT Cleaner 4. If water or other liquid is left on the panel’s surface for a long period, it can change the screen’s tint or stain it.
5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object, which could cause breakage or cracks. 6. CMOS-LSI circuits are used in the module, so guard against damage from electrostatic discharge. Be sure to wear a wrist or ankle ground when handling the module.
7. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods. 8. Do not store the module at temperatures below specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. 9. Do not disassemble the LCD module. Disassembly can cause malfunctions.
10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxime). These materials can release gas that can damage the panel’s polarization.
