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.

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

The beep sound is as follows:

 = long sound (about 0.4 sec.),        = short sound (about 0.2 sec.), Length between sounds is about 0.1 sec.

   Table of errors classified by beep sounds

(1 (long sound) -2-3-4)

(Length of bar shows length of sound.)

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.

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.

Stuck key on keyboard.

Keyboard not working.

Keyboard controller failed test.  May require replacing keyboard controller.

Unlock the system to proceed.

System RAM failed at offset nnnn of in the 64k block at which the error was detected.

Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.

Extended memory not working or not configured properly at offset nnnn.

The CMOS clock battery indicator shows the battery is dead.  Replace the battery and run Setup
to reconfigure the system.

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.

The timer test failed.  Requires repair of system board.

Real-time clock fails BIOS test.  May require board repair.

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.

Memory size found by POST differed from EISA CMOS.

CPU socket number for Multi-Processor error.

ServerBIOS2 test error:  Cannot write to EISA CMOS.

ServerBIOS2 test error: Cannot write to extended DMA (Direct Memory Access) registers.

ServerBIOS2 test error: Cannot generate software NMI (Non-Maskable Interrupt).

ServerBIOS2 test error: Fail-Safe Timer takes too long.

device address Conflict

Address conflict for specified device.

Run ISA or EISA Configuration Utility to resolve resource conflict for the specified device.

The hex number nnnn is a map of the bits at the RAM address which failed the memory test.

Each 1 (one) in the map indicates a failed bit.  See error 230,231 or 232 for offset address of the
failure in System, Extended or Shadow memory.

Problem with NVRAM (CMOS) data.

I/O device IRQ conflict error.

Operating system cannot be located on either drive A: or drive C:.  Enter Setup and see if fixed
disk and drive A: are properly identified.

Parity error found in the system bus.  BIOS attempts to locate the address and display it on the
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 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 ????.

Displayed after any recoverable error message.  Press <F1> to start the boot process or <F2> to
enter a Setup and change the settings. Write down and follow the information shown on the
screen.

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.

The power supply of the computer is turned on. 
" F2 " is pushed on the screen of  "Panasonic" while " press <F2 to enter Setup> " is displayed. 
The setup utility starts and then takes notes of the content of the BIOS setup of present set. 
" F9 " is pushed, " Yes" is selected on the screen of " Is the default value loaded? ", and " Enter" 
is pushed.

Notes

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"

Attention

Attention

"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. 

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.

Please let me discontinue diagnosing clicking         to end an automatic test.

Please click on the character of "D" "PC-Diagnostic utility" on the screen while pushing both of right 
"Shift" and left "Shift" keys.

All devices which can select the enhancing test make the setting of the enhancing test possible. 
The district device is made"FULL" display (enhancing test). 

The test begins clicking           .
