Operation This section gives an overview of the notebook’s operation. Turning the Notebook On and Off You can start and stop your notebook using its power button. However, at certain times you might want to use other methods to start or stop the notebook—depending on power considerations, types of active connections, and start-up time. Note This manual describes the notebook in its original factory configuration, with all settings at their default values. Table 1-3.
Checking the Status of the Notebook The main status lights on the front of the notebook report power status, battery status, and hard disk activity. Table 1-4. Main Status Lights (front of notebook) Meaning Power status On: notebook is on (even if the display is off). Blinking: notebook is in Standby mode. Off: notebook is off or in Hibernate mode. Hard disk drive activity On: notebook is accessing the hard disk drive. Battery status Green: The AC adapter is connected and the battery is fully charged.
Using Fn Hot Keys The combination of the Fn key plus another key creates a hot key—a shortcut key sequence—for various system controls. To use a hot key, press and hold Fn, press the appropriate second key, then release both keys. Table 1-6. Fn Hot Keys Hot Key Effect Fn+F1 Decreases the display brightness. Fn+F2 Increases the display brightness. Fn+F5 Toggles among the built-in display, an external display, and simultaneous display on both. Fn+F8 Toggles the built-in keypad on and off.
Resetting the Notebook Occasionally, Windows or the notebook might stop responding, so that you cannot turn the notebook off. If this happens, try the following in the order listed. Press the power button to restart. • If possible, shut down Windows: Windows XP: press CTRL+ALT+DEL, and then click Shut Down, Restart. Windows 2000: press CTRL+ALT+DEL, click Shut Down, and press the power button to restart.

Wireless models only: Remove the mini-PCI door and unplug the two antenna cables from the mini-PCI card. Do not remove the mini-PCI card at this time. 4. Remove the four screws that attach the motherboard to the bottom case. 5. From the back of the notebook, remove the six standoffs (two each from the external monitor port, serial port, and parallel port). 6.
Reassembly Notes Important After replacing the display assembly or motherboard, you must use the Service Utilities floppy disk to reprogram the EEPROM on the motherboard for the new display. 1. Download the Omnibook XE4000 Series service package from the Partnership web site (see page vii), and create a Service Utilities floppy disk as described in the package’s Readme file. 2. Plug in an AC adapter. 3. Insert the Service Utilities floppy disk in the floppy drive.
1. Remove the following components from the old motherboard and install onto the new motherboard: • CPU module • Wireless LAN mini-PCI card (if present) • SDRAM modules 2.

Install a new Microsoft Product ID label. 3. Transfer the old serial number label and install a new overlay, or create a new serial number label using the steps below. 4. Follow the “Reassembly Notes” on page 2-33.
Replacing the Left and Right Antennas If you need to remove or replace an antenna, see the figure below. Caution Handle the connector ends of the antennas carefully. Failure to do so could degrade notebook performance. Handle the antenna routing metal tabs in the bottom case carefully. These tabs can be easily broken. 1. Carefully remove both antennas from the old bottom case. 2. Route both antenna cables through the new bottom case as shown below.
Repairing the BIOS IC (HP Authorized Service Providers Only) The notebook’s BIOS IC cannot be replaced separately. If it is defective, you must replace the motherboard. In some cases, however, you might be able to reprogram a malfunctioning BIOS IC using either e-DiagTools for Windows, a BIOS floppy disk, or a Crisis Recovery floppy disk. If the notebook will boot sufficiently, use e-DiagTools for Windows or a BIOS floppy disk to reprogram the BIOS IC.
Using a BIOS Floppy Disk If you do not have a BIOS floppy disk, download the package from the Partnership web site (see page vii) under Product Support Information in the Service and Support Library. Follow the instructions for creating the BIOS floppy disk. Caution Make sure to use the correct BIOS floppy disk for the Omnibook model you are repairing. The program does not verify the Omnibook model, so you could accidentally install the wrong BIOS. 1. Insert the BIOS floppy disk in the floppy disk drive.
Removing Other Components (HP Authorized Service Providers Only) Required Equipment • Small Phillips screwdriver. • Small flat-blade screwdriver. Removal Procedure 1. Unplug the AC adapter, if present, and remove the battery. 2. Remove the assemblies and follow the additional steps listed in the table below. Table 2-5.

3 Troubleshooting and Diagnostics This chapter includes troubleshooting and diagnostic information for testing the functionality of the notebook, and for identifying faulty components: • ASP support information • Troubleshooting information Checking for customer abuse (page 3-3). Troubleshooting the problem (page 3-3). Verifying the repair (page 3-4). Suggestions for troubleshooting (page 3-5). • Diagnostic tools e-Diagtools diagnostic program (page 3-17). Power-on self-test (page 3-20).
Troubleshooting The suggestions in this section can help isolate and repair the cause of a problem. To ensure quality repair, follow the basic troubleshooting steps shown below. Check the customer's description of the problem and any supporting information. Check for customer abuse. Try to duplicate the customer's problem. Troubleshoot the problem using: - Diagnostic tools. - Troubleshooting suggestions. Verify the repair by testing the functionality of the complete unit. Figure 3-1.
Checking for Customer Abuse Some notebooks might appear to have been damaged by customer abuse. Use these guidelines to help determine if this is the case: • If the shipping box is seriously damaged, customer abuse cannot be declared. • If the damage could have a cause other than customer abuse, customer abuse cannot be declared. • If the notebook shows any of the following, customer abuse is declared: Missing parts. Broken plastic parts. Parts not original to the notebook.
Swapping modules that might be defective with others known to be good is generally an ideal way to find the module responsible for the problem. A failure symptom is rarely caused by more than one module, so you will not usually need to replace more than one to correct a particular failure. After you replace a module, the notebook will normally be in a confused state and lock up when you apply power.
Suggestions for Troubleshooting Table 3-2.
If you cannot isolate the cause of a problem using the above diagnostic tools, use the suggestions in the following table to help find the problem. Table 3-3.

Diagnostic Tools This section describes the following diagnostic tools you can use for troubleshooting and repairing the notebook: • Notebook e-Diagtools diagnostic program (below). • Power-on self-test (page 3-19). • Sycard PCCtest 450 PC card (page 3-25). • Windows Management Instrumentation (page 3-26). • BIOS Setup utility (page 3-27). e-Diagtools Diagnostic Program The hardware diagnostic programs provide two levels of testing: • User-level testing using a basic hardware test.
Running e-Diagtools The following procedure describes how to run e-Diagtools. The individual steps might differ slightly for different versions of e-Diagtools. 1. Click Start, Turn Off Computer (or Shut Down), Restart. 2. When the HP logo appears, press F10 to start the diagnostic test. The first time you run the program, you are prompted to select the language for the program. 3. When the menu appears, press F2 to run e-Diagtools. 4.
Interpreting the Results The e-Diagtools diagnostic program returns test groups, error codes, and suggestions for repair and/or follow-up actions. The basic hardware test shows a recommended replacement part. To help interpret the results of the e-Diagtools tests, refer to the following: • e-Diagtools Support Ticket on page 3-18.
Power-On Self-Test Note If Quiet Boot is enabled in BIOS Setup (the default setting), press Esc during boot to see POST messages. When the notebook boots, its system BIOS runs a series of initialization routines and diagnostic tests called POST (Power-On Self-Test). The BIOS will not boot the notebook’s operating system if the system memory, CPU, DMA, or interrupt controller fails the POST diagnostic tests.

Hewlett-Packard Display Quality Statement TFT display manufacturing is a highly precise but imperfect technology, and manufacturers cannot produce large displays that are cosmetically perfect. Most, if not all, TFT displays exhibit some level of cosmetic imperfection. These cosmetic imperfections might be visible to the customer under varying display conditions, and can appear as bright, dim, or dark spots.
