17 TroubleshootingList of Error CodesThe following is a list of the messages that BIOS can display. Most of them occur during POST. Some of themdisplay information about a hardware device, e.g., the amount of memory installed. Others may indicate aproblem with a device, such as the way it has been configured. Following the list are explanations of the mes-sages and remedies for reported problems.If your system displays one of except the messages marked below with an asterisk (*), write down the messageand contact Panasonic Technical Support. If your system fails after you make changes in the Setup menus, resetthe computer, enter Setup and install Setup defaults or correct the error.0200 Failure Fixed DiskFixed disk in not working or not configured properly. Check to see if fixed disk is attached properly. Run Setup. Find out if thefixed-disk type is correctly identified.0210 Stuck keyStuck key on keyboard.0211 Keyboard errorKeyboard not working.0212 Keyboard Controller FailedKeyboard controller failed test. May require replacing keyboard controller.0213 Keyboard locked - Unlock key switchUnlock the system to proceed.0230 System RAM Failed at offset : nnnnSystem RAM failed at offset nnnn of in the 64k block at which the error was detected.0231 Shadow RAM Failed at offset : nnnnShadow RAM failed at offset nnnn of the 64k block at which the error was detected.0232 Extended RAM Failed at offset : nnnnExtended memory not working or not configured properly at offset nnnn.0250 System battery is dead - Replace and run SETUPThe 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 usedSystem 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 failure was caused byincorrect values and they are not corrected, the next boot will likely fail. On systems with control of wait states, improper Setupsettings can also terminate POST and cause this error on the next boot. Run Setup and verify that the wait-state configuration iscorrect. This error is cleared the next time the system is booted.0281 Memory Size found by POST differed from CMOSMemory size found by POST differed from CMOS.02B0 Diskette drive A errorDrive A: is present but fails the BIOS POST diskette tests.
