HP Omnibook XE3 (Technology Code GF) Troubleshooting and Diagnostics 3-29 Power-On Self-Test 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. 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. First, confirm the failure by performing a “clean” boot: If the computer fails to restart with a clean boot, it requires repair. 1. Remove all accessories, including SDRAM modules, port replicator, PC cards, printer, external monitor, pointing device, and keyboard. 2. Provide “clean” AC power—no auto adapter or unusual AC adapter configuration. 3. Press the system-off switch to return the notebook to a known state. 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 3-4. 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. 1-3-1-1 Test DRAM refresh. 1-3-1-3 Test NS87570 Keyboard Controller (part of motherboard). 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 motherboard DIP switches) or external ROM checksum failure. 1 long-5 short Display DIP switches and EEPROM settings do not match (check DIP switch settings). * Up to four groups of short beeps, except as noted. 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.

HP Omnibook XE3 (Technology Code GF) Troubleshooting and Diagnostics 3-33 Desktop and Windows Management Interfaces (DMI/WMI) Note HP TopTools are not supported on Pavilion models. The Desktop Management Interface and Windows Management Instrumentation are basically sets of rules for accessing information about a computer. DMI/WMI allows an application to determine, for example, the operating system being used, which hardware and software components are in the computer, and possibly whether any of the components need replacing. A local or remote application can use the DMI/WMI interface to check which hardware and software components are installed on your computer, and may be able to tell how well they are working or if they need replacement. Installing the DMI Package The DMI package is either preinstalled on the computer’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. Install the package as follows. To install the DMI preloaded on the hard disk: • In Windows, click Start, Programs (or All Programs), HP TopTools for Notebooks, Setup. To install the DMI from the Recovery CDs or from floppy disks: 1. Insert Recovery CD disk 1 into the CD/DVD drive, or insert floppy 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. Using DMI/WMI For a complete description of how to use DMI/WMI, see the following documentation provided with the computer: • A README.TXT file. • A Windows online help file describing Hewlett-Packard’s implementation of DMI (group and attribute definitions): click Start, Programs (or All Programs), HP TopTools for Notebooks, HP TopTools Help. Uninstalling the DMI Package 1. Click Start, Programs (or All Programs), HP TopTools for Notebooks, Uninstall DMI (Windows 98) or Uninstall WMI (Windows 2000 or XP). 2. Restart the notebook.

3-36 Troubleshooting and Diagnostics HP Omnibook XE3 (Technology Code GF) Updating the Notebook’s BIOS Hewlett-Packard may from time to time provide updates to the notebook’s BIOS. Use e-DiagTools for Windows to download and install these updates as needed. Caution The BIOS update completely replaces the previous BIOS, so follow these directions exactly or you might damage the notebook. The BIOS update also resets the configurations in the BIOS Setup utility—except for BIOS passwords—so record these before performing the update. Update the notebook’s BIOS as follows: 1. In Windows, exit any programs that are running. 2. Undock the notebook if it is docked, and remove any PC cards from it. 3. Connect the AC adapter to the notebook. 4. Connect any cables or equipment needed to connect to the Internet. 5. Click Start, Programs (or All Programs), HP e-DiagTools, e-DiagTools for Windows. 6. Click Update, select Download New and click OK. Follow the instructions that appear. Once the update process begins, do not interrupt it. The first time you make an Internet connection from this program on a particular unit, click Change Settings in the Connect window to define your connection settings. 7. When the process is completed, reset the system: insert a pin or straightened paper clip into the recess on the left side of the computer, underneath the PC card eject buttons. BIOS updates are also available from the HP Customer Care web site (www.hp.com/go/support).
