							3-22 Troubleshooting and Diagnostics Service Manual
The following table lists POST messages and explanations for reported problems. If the system fails
after you make changes in BIOS Setup, reset the notebook, enter BIOS Setup, and install the defaults
or correct the error.
  Table 3-5. POST Messages
MessageDescription
0200 Failure Fixed Disk
Fixed (hard) disk is not working or not configured properly. Make sure the hard disk is
installed properly. Run BIOS Setup and make sure the hard disk type is correctly identified.
0210 Stuck key
Stuck key on keyboard.
0211 Keyboard error
Keyboard is not working.
0212 Keyboard Controller Failed
Keyboard controller failed the test. might require replacing the motherboard (contains the
keyboard controller).
0213 Keyboard locked – Unlock key switch
Unlock the system to proceed.
0220 Monitor type does not match CMOS – Run SETUP
Monitor type is not correctly identified in BIOS Setup.
0230 Shadow RAM Failed at offset: nnnn
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
0231 System RAM Failed at offset: nnnn
System RAM failed at offset nnnn of the 64k block at which the error was detected.
0232 Extended RAM Failed at offset: nnnn
Extended memory is not working or not configured properly at offset nnnn. Update to the
latest BIOS version.
0250 System battery is dead – Replace and run SETUP
CMOS clock battery indicator shows that the CMOS battery is dead. Connect the AC adapter
for at least 24 hours, then run BIOS 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 that
changes CMOS data. In response, the BIOS has installed the default Setup values. Use
BIOS Setup to modify these values if needed. If the error persists, check the system battery.
Connect the AC adapter for at least 24 hours; replace the motherboard.
0260 System timer error
Timer test failed. Replace the motherboard.
0270 Real time clock error
Real-time clock failed the BIOS test. Might require replacing the motherboard.
0271 Check date and time settings
BIOS found the date or time to be out of range, and reset the real-time clock. You might need
to use BIOS Setup to reset the legal date.
0280 Previous boot incomplete – Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run
BIOS Setup. If the failure was caused by incorrect values that are not corrected, the next boot
will likely fail. This error is cleared the next time the system is booted.
0281 Memory Size found by POST differed from CMOS
Memory size found by POST differed from that specified in CMOS.
02B0 Diskette drive A error
Drive A: is present but fails the BIOS POST diskette tests. Make sure the drive is defined with
the proper diskette type in BIOS Setup and that the drive is connected correctly.
02B2 Incorrect Drive A type – run SETUP
Type of floppy drive A: not correctly identified in BIOS Setup.
02D0 System cache error – Cache disabled
RAM cache failed and BIOS disabled the cache. May require replacing the motherboard.
A disabled cache slows system performance considerably.
02F0: CPU ID:
CPU socket number for Multi-Processor error.

Sycard PCCtest 450/460 PC Card (Optional)
The PCCtest 450 and 460 cards (version 1.05) from Sycard Technology are the only recommended
diagnostic tools that test the functionality of the PCMCIA slots using a PCMCIA card. Each is a
Type II PC card that works with test software to exercise PCMCIA functions. (For details, see the
Sycard Technology Web site: http://www.sycard.com).
The PCCtest product contains these components:
 • 
PCCtest 450 or 460 (revision 1.05) PC card.
 • 
PCCtest 450/460 software disk. (Software updates are available at the Sycard Technology Web
site.)
 • 
Configuration headers (PC card/16-bit and CardBus/32-bit) that attach to the card.
You will also need a CardBus extender card (such as the Sycard PCCextend 70) to avoid wear on the
Sycard PCMCIA connector.
Use the following tests to check the function of the notebook’s PCMCIA slots. See the Sycard
documentation for details about running the tests.

Windows Management Instrumentation (WMI)
The Windows Management Instrumentation is basically sets of rules for accessing information about a
notebook. WMI allows an application to determine, for example, the operating system being used,
which hardware and software components are in the notebook, and possibly whether any of the
components need replacing. A local or remote application can use the WMI interface to check which
hardware and software components are installed on your notebook, and might be able to tell how well
they are working or if they need replacement.
Installing the WMI Package
The WMI package is either preinstalled on the notebook’s hard disk or can be downloaded from
http://www.hp.com/toptools (the contents are the same in both cases). The package must be properly
installed before it can be used.
To install the WMI preloaded on the hard disk:
 
1. 
Start Windows, if it is not already running.
 
2. 
Click Start > Programs (or All Programs) > Hewlett-Packard > HP Toptools Agent > Setup.
Using WMI
For a complete description of how to use WMI, see the following documentation provided with the
notebook:
 • 
A README.TXT file: click Start > Programs > Hewlett-Packard > HP Toptools Agent >
Read me.
 • 
A Windows online help file describing Hewlett-Packard’s implementation of WMI (group and
attribute definitions): click Start > Programs Hewlett-Packard > HP Toptools Agent > HP Toptools
Help.
Uninstalling the WMI Package
 
1. 
Click Start > Programs (or All Programs) > Hewlett-Packard > HP Toptools Agent > Uninstall
WMI.
 
2. 
Restart the notebook.
BIOS Setup Utility
The BIOS Setup utility provides access to the notebook’s basic configuration settings. It is independent
of the operating system.
Running the BIOS Setup Utility
 
1. 
Close all applications, then restart the notebook: click Start > Turn Off Computer > Restart. (If
necessary, you can press Ctrl+Alt+Del to restart.)
 
2. 
When the HP logo appears, press F2 to enter the BIOS Setup utility.

3. 
The pointing devices are not active in BIOS Setup, so you will need to use the keyboard to
navigate:
 • 
Press the LEFT and RIGHT arrow keys to move among menus.
 • 
Press the UP and DOWN arrow keys to move among parameters in a menu.
 • 
Press F5 or F6 to move through values for the current parameter, or press Enter to change a
setting.
 
4. 
After you select the options you want, press F10 or use the Exit menu to exit BIOS Setup.
 
If the settings cause a conflict between devices during reboot, the system prompts you to run BIOS
Setup, and marks the conflicting settings.

The listings in the following table are for the initial BIOS release and might differ somewhat for
other models.
