Error code Error message Description/corrective action
0250 System battery is dead -
Replace and run SETUP
The CMOS clock battery indicator shows the system battery is dead.
1 Replace the system battery following the procedures in the HP ProLiant
DL180 Server Maintenance and Service Guide.
2 Run Setup to reconfigure the system.
0251 System CMOS checksum
bad - Default
configuration used
The settings in the Setup Utility have been corrupted or modified
incorrectly, perhaps by an application program that changes data
stored in CMOS. You can either:
• Load the system default values following the procedures on page
40.
• Access Setup and enter your own custom values.
If the error persists, check the system battery or contact your HP
Customer Support provider.
0260 System timer error The timer test failed. Requires repair of the system board.
0270 Real time clock error Real-Time Clock (RTC) fails BIOS hardware test. May require board
repair.
0271 Check date and time
settings
BIOS found date or time out of range and reset the RTC. May require
setting legal date (1991-2099). Access Setup and check the values in
the System Timeand System Datefields of the Main menu.
0280 Previous boot incomplete
– Default configuration
used
Initial bootup failed. BIOS automatically loads the default system values,
then boot again.
0281 Memory size found by
POST differed from
CMOS
The user has added or removed a memory module, thus a memory size
that is different from the previous bootup.
02F5 DMA test failed The DMA control test failed.
02F6 Software NMI failed An NMI signal is detected and/or a user has pressed the NMI switch.
POST beep codes
There are several POST routines that issue a POST terminal error and shut down the system if they fail.
Before shutting down the system, the terminal-error handler issues a beep code signifying the test
point error, writes the error to port 80h, attempts to initialize the video, and writes the error in the
upper left corner of the screen (using both mono and color adapters).
NOTE: An optional POST code expansion board must be installed in the server for the POST beep
codes to be audible.
The POST routines cannot display messages when an error occurs if any of the following are present:
• The error occurs before the video display is initialized.
• The video configuration fails, either there’s no graphics card installed or the one installed is
faulty.
• An external ROM module does not properly checksum to zero.
• The system memory cannot be initialized.
