3. Technical Information
3.1. System Overview
3.1.1 System Configuration
The main system is made up of a Main board, a RJ board, an IR board, a Battery board and a TS13 board. The CPU operates at 1.6V, 1.35V(core)/2.5V; the main memory at 3.3V; the core logic at 3.3V/5V; and the other main chips at 3.3V.

3.1.2 Power Supply System
The power supply used by the Main board is generated on the Main board based on the voltage from the AC adapter.

Power Supply System VC system (VC5, VC3, VC25, VC18, VC16, VC15)

4-1

4.2. Power-On Self Test (Boot Check)
4.2.1 Outline of POST
The set has a boot check function called POST (Power-On Self Test) in it. The condition of the main body is diagnosed by checking beep sound or error code. l Start .............Test begins automatically when power switch is set to ON. l Normal finish .....After memory checking, a beep sound is issued once and the set is placed into automatic stop. Note: If no error occurs, nothing is displayed. (No display of OK, etc.)

4.2.2 Error Diagnosis by Checking Beep Signal Sound
The beep sound is as follows: (1 (long sound) -2-3-4) (Length of bar shows length of sound.) = long sound (about 0.4 sec.), l Table of errors classified by beep sounds Diagnosis Main board Beep signal sound 1(long sound)-2 1-2-2-3 1-3-1-1 1-3-1-3 1-3-4-1 1-3-4-3 1-4-1-1 2-1-2-3 2-2-3-1 BIOS ROM error BIOS ROM error RAM error Keyboard controller error RAM error RAM error RAM error BIOS ROM error Occurrence of unexpected offering Error message = short sound (about 0.2 sec.), Length between sounds is about 0.1 sec.

(Note) A beep sound is also issued in case of other I/O trouble.

4.3. List of Error Codes
The following is a list of the messages that BIOS can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. Following the list are explanations of the messages and remedies for reported problems. If your system displays one of except the messages marked below with an asterisk (*), write down the message and contact Panasonic Technical Support. If your system fails after you make changes in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the error. 0200 Failure Fixed Disk Fixed disk in not working or not configured properly. Check to see if fixed disk is attached properly. Run Setup. Find out if the fixed-disk type is correctly identified. 0210 Stuck key Stuck key on keyboard. 0211 Keyboard error Keyboard not working. 0212 Keyboard Controller Failed Keyboard controller failed test. May require replacing keyboard controller. 0213 Keyboard locked - Unlock key switch Unlock the system to proceed. 0230 System RAM Failed at offset : nnnn System RAM failed at offset nnnn of in the 64k block at which the error was detected. 0231 Shadow RAM Failed at offset : nnnn Shadow RAM failed at offset nnnn of the 64k block at which the error was detected. 0232 Extended RAM Failed at offset : nnnn Extended memory not working or not configured properly at offset nnnn. 0250 System battery is dead - Replace and run SETUP The CMOS clock battery indicator shows the battery is dead. Replace the battery and run Setup to reconfigure the system. *0251 System CMOS checksum bad - Default configuration used System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOS. The BIOS installed Default SETUP Values. If you do not want these values, enter Setup and enter your own values. If the error persists, check the system battery or contact Panasonic Technical Support. 0260 System timer error The timer test failed. Requires repair of system board. 0270 Real time clock error Real-time clock fails BIOS test. May require board repair. *0280 Previous boot incomplete - Default configuration used Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail. On systems with control of wait states, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that the wait-state configuration is correct. This error is cleared the next time the system is booted. 0281 Memory Size found by POST differed from EISA CMOS Memory size found by POST differed from EISA CMOS. 02B0 Diskette drive A error 02B1 Diskette drive B error Drive A: or B: is present but fails the BIOS POST diskette tests. Check to see that the drive is defined with the proper diskette type in Setup and that the diskette drive is attached correctly. 02B2 Incorrect Drive A type - run SETUP Type of floppy drive A: not correctly identified in Setup. 02B3 Incorrect Drive B type - run SETUP Type of floppy drive B: not correctly identified in Setup. 02D0 System cache error - Cache disabled Contact Panasonic Technical Support.

5.1.2 Preparation
(1) Connect the AC Adapter and External Printer to the computer. (2) The System Setup should be set to the factory setting values by executing the "SETUP UTILITY" which can be invoked by .2 key at the POST. If not, the messages and items of the diagnostic test may not be displayed properly on the LCD. (3) The serial port must be enabled in the "SETUP UTILITY" in order to execute the "1st SERIAL PORT" test. (4) Connect the serial loopback plug. (5) In order to test the parallel port with Loopback Plug, disconnect the printer cable and connect the parallel loopback plug with Power O...

5.1.3 NOTICE
When "Enter password" is displayed, use "Password Skipping Plug" in order to skip the user password. 1) Connect the parallel plug to the parallel port. 2) Connect the PS/2 mouse plug to the mouse port. 3) Power on the computer. The wiring of the parallel plug is described below. Connect pins 2-5-6-8-11-13-15-18-19-20-21-22-23 to Shield GND (PS/2 mouse plug pin 3.) Connect pins 3-4-7-9-10-12 to VC5 (PS/2 mouse plug pin 4) with 4.7KW each.

CAUTION The plug described above must be used for servicing purpose only. Do not use it for other than the above purpose and ensure that it remains confidential. Using the plug enables the user to skip the previous password and disable the password.
