screen’, etc.

2. Explanation of each trouble, mainly symptom of trouble in operation.

● Flow Chart

Pay attention to the following points when in pursuit of the cause of a troubleshooting.

1. Peripheral apparatus connected with the set should all be removed before operation check.

5 Power-On Self Test (Boot Check)

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.

z Start .............Test begins automatically when power switch is set to ON.

z 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.)

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.),

= short sound (about 0.2 sec.), Length between sounds is about 0.1 sec.

6 List of Error Codes <Only when the port replicator is connected>

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 termi-

nate 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.

failure in System, Extended or Shadow memory.

Invalid System Configuration Data

Problem with NVRAM (CMOS) data.

I/O device IRQ conflict

I/O device IRQ conflict error.

screen. If it cannot locate the address, it displays ????. Parity is a method for checking errors

in binary data. A parity error indicates that some data has been corrupted.

Parity Check 2 nnnn

Parity error found in the I/O bus. BIOS attempts to locate the address and display it on the

screen. If it cannot locate the address, it displays ????.

Press <F1> to resume, <F2> to Setup

7 Self Diagnosis Test

As for the self-diagnosis test(PC-Diagnostic utility) to use this model, a standard test and the

enhancing test by the module of the main body building in are possible.

Notes

To skip BIOS password

Use <Ctrl>+<F10> key to skip BIOS password or authentication of fingerprint.

This key is only for entering DIAG mode. Not available to boot the computer.

If customer set "HDD Lock", the DIAG program cannot perform HDD test.

*This key is for service purpose only. Do not disclose this information to unrelated others.

1. Beginning of self-diagnosis test

1-1. Setting of content of setup

1. The power supply of the computer is turned on.

2. " F2 " is pushed on the screen of "Panasonic" while " press <F2 to enter Setup> " is displayed.

3. The setup utility starts and then takes notes of the content of the BIOS setup of present set.

4. " F9 " is pushed, " Yes" is selected on the screen of " Is the default value loaded? ", and " Enter"

is pushed.

5. " F10 " is pushed.

6. " Yes" is selected on the screen of the setup confirmation, and " Enter" is pushed.

7. The computer starts automatically.

Attention

If the device which can be set is set to "Invalidity" by "Advanced" or "Security" menu, becomes an

error by "PC-Diagnostic utility".

(It is judged that the device which can be set to "Invalidity" by "Main" menu such as "Flat pad" is

normal if the controller operates normally though sets to "Invalidity" by the setup. )

In the model with built-in DVD of the USB connection, even if DVD is normal, becomes an error if

legacy USB is set to "Invalidity"

1-2. When you execute an automatic test

"Ctrl" + "F7" is pushed while the "Panasonic" start screen is displayed after the computer is started.

The test of all devices begins automatically by "PC-Diagnostic utility"’s starting.

Attention

It is a test which the customer who bought PC can execute. (As for HDD, the enhancing test is also

possible.)

A flat pad does not work for a while after starting "PC-Diagnostic utility".

The movement of a flat pad might become abnormal If after RAM begins from the CPU/System

test, a flat pad will be operated in about 30 seconds. In that case,restarts pushing"Alt" + "Ctrl" +

"Del" key. Or, please start "PC-Diagnostic utility" again after doing the power supply switch in the

slide, and turning off the power supply.
