Power-On Self-Test
  Note
 
If Quiet Boot is enabled in BIOS Setup (the default setting), press ESC during boot to see POST
messages.
The POST (Power-On Self-Test) is a series of initialization routines and diagnostic tests that the
system BIOS runs when the notebook boots. The system BIOS will not boot the operating system if
system memory, the CPU, DMA, or the interrupt controller fails the POST diagnostic tests. POST
progress is indicated by a sequence of codes, and error messages are displayed if possible.
You should not necessarily interpret the failure of one or more POST tests as a hardware, software, or
firmware failure. First, confirm the failure by performing a “clean” boot:
 · Remove all accessories, including SDRAM modules, port replicator, PC cards, printer, external
monitor, pointing device, and keyboard.
 · Provide “clean” AC power—no auto adapter or unusual AC adapter configuration.
 · Press the system-off switch to return the notebook to a known state.
If the notebook fails to boot with a clean boot, it requires repair. If an error message appears, confirm
the problem using other diagnostic tools. Not all POST messages indicate a hardware, software, or
firmware failure—some messages are for information only.
If the BIOS detects a terminal error condition, it halts POST after issuing a terminal error beep code
(see the following table). The beep code indicates the POST routine in which the terminal error
occurred.
 Table 3-1. POST Terminal-Error Beep Codes
Beep Codes*POST Description
1 One short beep before boot.
1-2 Search for option ROMs.
1-2-2-3 BIOS ROM checksum.

1-3-4-1 RAM failure on address line xxxx.
1-3-4-3 RAM failure on data bits xxxx of low byte of memory bus.
1-4-1-1 RAM failure on data bits xxxx of high byte of memory bus.
2-1-2-3 Check ROM copyright notice.
2-2-3-1 Test for unexpected interrupts.
1 long-2 short Improper video configuration (check video PCA DIP switches, replace video PCA)
or external ROM checksum failure.
1 long-5 short Display DIP switches and EEPROM settings do not match (check DIP switch
settings, reprogram EEPROM).
* Up to four groups of short beeps, except as noted.

after you make changes in BIOS Setup, reset the notebook, enter BIOS Setup, and install the defaults
or correct the error.

BIOS version.
0250 System battery is dead – Replace and run SETUP
The CMOS clock battery indicator shows the battery is dead. Connect the AC adapter for at
least 24 hours. Replace the motherboard.
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 BIOS Setup and enter your own values. If the error persists, check
the system battery. Connect the AC adapter for at least 24 hours; replace the motherboard.

0270 Real time clock error
Real-time clock fails BIOS test. May need to replace motherboard.
0280 Previous boot incomplete – Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run
BIOS Setup. If failure was caused by incorrect values and these values 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 CMOS.
02B0 Diskette drive A error

Desktop Management Interface (DMI)
The Desktop Management Interface (DMI) is basically a set of rules for accessing information about a
personal computer. Using DMI, an application program can determine, for example, which hardware
and software components are present in the computer, the operating system being used, and the
number of accessory board slots available. Using the DMI interface, a local or remote application
program can check which hardware and software components are installed on your notebook, and may
be able to tell how well they are working or whether any needs replacing. All this information is
stored in a special Management Information Format (MIF) file, installed on each computer as part of
the DMI package.
Installing the DMI Package
The DMI package is included with your notebook, but must be properly installed before it can be
used. Install the package as follows.
To install the DMI preloaded on the hard disk:
 · In Windows, click Start, Programs, HP TopTools for Notebooks, Setup.
To install the DMI from the Recovery CD, or from floppy disks:
 1. Insert the Recovery CD, into the CD-ROM/DVD drive, or insert disk #1 into the floppy drive.
 2. Select and run the SETUP program from the dmi\disk1 directory on the CD (under \hp\Drivers),
or from floppy disk #1.
Contents of the DMI Package
The DMI software and associated documentation is supplied either preinstalled on the notebook’s
hard disk drive or on the Recovery CD. The contents of the package are the same for both.
Since the information accessed by the DMI software is specific to each particular computer, it must be
installed on each computer separately. The DMI package included with a notebook can therefore be
used only with that notebook.
The DMI package includes the following software:
 · A Microsoft Windows utility (SETUP.EXE) to install and initialize the DMI software.
 · A Windows utility, HP TopTools. After DMI is installed, this utility can display information
about the notebook through the DMI.
 · A Management Information Format (MIF) file. This file contains information about everything on
the notebook that can be controlled using DMI facilities, and is initialized during installation.
 · A component code, identifying the version of MIF file to use for specific models of HP notebook
computers.
 · Windows-compatible DMTF Service Layer software, which controls access to the DMI.
 · A client agent. The HP Remote DMI Agent is a DMI application and also a network server-side
stream-based application. The Remote Agent is listening for Remote Application connection
requests. If the main window of the Remote Agent is hidden, then no icon appears on the screen
when it is running. 
						

							HP OmniBook XE3 Troubleshooting and Diagnostics 3-29
Using the DMI Interface
For a complete explanation of how to take full advantage of DMI, see the following documentation
(provided with your notebook):
 · A README.TXT file.
 · A Windows online help file describing Hewlett-Packard’s implementation of DMI (group and
attribute definitions). Since not all models support all of Hewlett-Packard enhanced features, this
document also describes any restrictions that apply.
Description of DMI
The Desktop Management Interface (DMI) is the result of the efforts of the Desktop Management
Task Force (DMTF) founded in 1992 by a group of leading computer manufacturers—including
Hewlett-Packard—to define a standard method of managing the physical and logical components of
personal computers.
Hewlett-Packard has developed a number of extensions to DMI to allow it to manage the enhanced
features of HP notebook computers, including passwords and tattooing (identifying a computer using
a unique string of characters).
For full details of the structure of the MIF file (including an explanation of the fields of groups and
attributes, and how to write an application program that accesses this information), access the DMTF
FTP server ftp.dmtf.org or the DMTF web pages at the http://www.dmtf.org.
Uninstalling the DMI Package
 1. Click Start, Programs, HP TopTools for Notebooks, Uninstall DMI.
 2. Restart the notebook.

BIOS Setup Utility
The BIOS Setup utility provides access to basic configuration settings. It is independent of the
operating system.
Running the BIOS Setup Utility
 1. Close all applications, then click Start, Shut Down, Reboot. (If necessary, you can press
CTRL+ALT+DEL to reboot.)
 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 again, and marks the conflicting settings.
