Internal Design
The motherboard PCA is the central component of the OmniBook's design. It plays a role in virtually all system functions. The CPU module and most other subsystems connect to the motherboard. The following figure shows the connections among the OmniBook's replaceable electronic modules. In addition, the table on page 1-14 lists the roles that the replaceable modules play in each of the OmniBook's functional subsystems.

· Slide the cover down into place so the retainer tab engages the casing. · Carefully put the pin connector back onto the pins on the end of the new hard drive. Work at each end alternately so that the connector slides on evenly without bending the connector pins. · Of the six screws that go in the holder and drive case, the thinner screws go nearest the connector.
Important If you are installing a new hard drive, create a Hibernate partition on the drive before loading any software--see "Creating a Hibernate Partition," below.

Creating a Hibernate Partition
When you install a new hard drive, always create a Hibernate partition on the drive before loading any software. 1. Plug in the ac adapter. 2. Insert the Recovery CD in the CD-ROM drive. 3. Shut down and restart the computer. When you see the HP logo, press ESC twice. 4. Select the CD or DVD drive as the boot device. 5. When the Recovery CD dialog box appears, follow the displayed instructions. If prompted, accept the recommended partition size. If you install the factory software, the recovery process can take up to 10 minutes. If you want to create the Hibernate/diagnostics partition without installing the factory software, click Advanced and select the option to not install the operating system. 6. When prompted to reboot the computer, press CTRL+ALT+DEL and follow any instructions that appear onscreen.

This package contains the following: · Image for creating a bootable Display Update floppy disk. · Image for creating a bootable Service Utilities floppy disk. · Readme file that explains how to create and use the above floppy disks. Use the Display Update floppy disk and Service Utilities floppy disk as described in the Readme file to update the following data in the EEPROM on the motherboard: · LCD operating information. · Computer's serial number. · UUID (unique network ID). · Service ID.

Replacing the Bottom Case
Installation Procedure

1. Install a new Microsoft Product ID label. 2. Transfer the old serial number label and install a new overlay, or create a new serial number label using the steps below. 3. Follow the "Reassembly Notes" on page 2-23.
Installing a New Serial Number Label

Download the latest version of the serial number label template (Microsoft Word format) from the Partnership Web site (see page vi) under Support/Service in Technical Support Information. Store it with other Word templates on a PC connected to a laser printer. The latest version includes fields for warranty period and manufacturing location. 1. Open a new document based on the serial label template. 2. Enter the information from the old serial label, and print the new label on plain white paper. The new label does not have barcodes. 3. Carefully cut out the new serial label just inside the border and place it into the inner recess in the bottom case. The bottom of the label goes toward the front of the case. 4. While holding the paper label in place, attach a serial label overlay into the outer recess. It covers and protects the serial label.

Repairing the BIOS IC
(HP Authorized Service Providers Only)
The BIOS IC of the OmniBook 6000 is not replaceable: · If the BIOS IC is defective, you must replace the power supply PCA. · However, if the BIOS IC might only be corrupted, you can attempt to repair it using a Crisis Recovery floppy--see the information below.
Note: Reprogramming the BIOS IC A new BIOS IC contains only enough basic programming to boot the OmniBook. After installing a new power supply PCA, you must reprogram the BIOS IC, preferably with the latest BIOS. You can download the latest BIOS from the HP Notebook Web site (see page vi)--follow the directions provided.

If you do not have a BIOS Crisis Recovery floppy, download the package from the Partnership Web site (see page vi) under Product Support Information in the Service and Support Library. Follow the instructions for creating the floppy.

Caution
Make sure you are using the correct BIOS Crisis Recovery floppy for the OmniBook model you are repairing. The program does not verify the OmniBook model, so you could install the wrong BIOS image.

1. Insert the BIOS Crisis Recovery floppy in the floppy drive. 2. If the computer does not boot from the BIOS Crisis Recovery floppy, try plugging the boot-block jumper into the OmniBook parallel port, then go to the next step. See the wiring diagram below. (In many situations you can skip this step--especially if the computer previously displayed a BIOS checksum error.) 3. Turn on the computer and allow it to boot from the floppy disk. If the computer does not turn on at all, do the following steps to boot from the floppy disk: · Unplug the ac adapter. · Press and hold Fn+B. · Plug in the ac adapter. · Release Fn+B. 4. Wait while the BIOS is reprogrammed--the display is blank for a minute or more while this happens. If you plugged in a boot block jumper, unplug it before the computer automatically reboots. 5. After the BIOS is repaired and reprogrammed, check the BIOS version to see whether it is the latest version. If necessary, reprogram the BIOS IC--see the note at the beginning of this topic.
