Technology Codes

HP does not change the name of a product every time the product’s technology changes. While this helps ensure continuing market momentum for HP products, it complicates technology deployment and support processes.

To help solve this problem, HP has added a technology code to the serial number of each of its products. Since the BIOS must be matched to the notebook’s hardware, the same code is used for the BIOS and the hardware. This manual refers to technology code deferences where applicable.

The table below shows the technology codes and the changes they signify for the products. Before downloading software or drivers or performing repairs, note the technology code for the HP notebook model.

Note that the first two characters of the BIOS ID (for example, IB.M1.02) indicate the hardware technology. You can also determine the BIOS ID using the BIOS configuration utility, or by pressing Esc during the boot process when the HP logo appears.

This manual contains service information for products with the following technology code.

Using the CD or DVD Player (selected models)

The multimedia buttons on the front of the notebook control the CD/DVD player, and work in much the same way as do the controls of a standalone CD or DVD player. The player operates whether the notebook is on, off, on standby, or in hibernation. (When the notebook is on, the volume control buttons also govern the volume for most audio applications.)

If the notebook is off, on standby, or in hibernation, slide the multimedia power switch to the left to activate the player. For details about using the CD/DVD player, see the notebook’s Reference Guide.

Internal Design

The motherboard PCA is the central component of the notebook’s design, and plays a role in virtually all system functions. The CPU module and most other subsystems connect to the motherboard.

The following figure shows the electrical connections among the notebook’s replaceable electronic modules. In addition, the table on page 1-15 lists the roles that the replaceable modules play in each of the notebook’s functional subsystems.

Caution

Always provide proper grounding when performing repairs. Without proper grounding, an electrostatic discharge can damage the notebook and its components.

Notes

To reassemble a component, perform the removal procedure in reverse order. Any special notes required for reassembly are included at the end of each section.

Symbols like this are used throughout this chapter to show approximate full-size screw outlines. Use these to verify the sizes of screws before you install them. Installing a wrong-size screw can damage the notebook. (The symbol shown represents an M2.5×5mm T-head screw.)

Important

If you are installing a new hard disk drive, install the factory software and operating system on the drive before loading any additional software—see “Recovering and Reinstalling Software,” below.

HP Pavilion zt1100/xz100 Omnibook xt1000 Removal and Replacement 2-7

Recovering and Reinstalling Software

Use the Recovery CDs to reinstall the original factory software and operating system. The Recovery CDs also provide all HP notebook–specific Windows drivers, which are available in the following

locations:

• On the hard drive, under c:\hp\drivers.

• On the Recovery CDs, under \hp\drivers.

• On the HP Business Support web site (www.hp.com/go/bizsupport). This web site contains the

latest updates of software drivers for various operating systems.

To recover the factory software installation

The following procedure describes how to recover the notebook’s original software and operating system. This process can take up to 15 minutes to complete. (For more information about recovering the factory software installation, see the file readme.txt in the root directory of the Recovery CDs.)

Caution

Be sure to back up the hard disk before proceeding. This procedure formats the hard disk, which erases all data on the disk. After formatting, you must reinstall any applications.

Do not interrupt the following process or unplug the AC adapter until the process is complete.

1. Back up all data from the hard disk.

2. Connect the AC adapter to the notebook. This is necessary to provide an uninterrupted power source: the notebook’s battery alone is not adequate.

3. Insert Recovery CD disk 1 into the notebook’s CD/DVD drive. If the notebook is turned off, use a pin or straightened paper clip to press the release switch on the drive door to open it.

4. Turn on or restart the notebook.

5. When the HP logo appears, press Esc to display the Boot menu.

6. Use the arrow keys to select the CD/DVD drive as the first boot device, then press Enter.

7. When the Recovery CD dialog box appears, follow the displayed instructions. If prompted, accept the recommended partition size.

To create the Utility partition without installing the factory software, click Advanced and select not to install the operating system.

If the hard disk is partitioned into several drives, you can install the factory software on drive C without affecting other drives. Click Advanced and select to restore only the C partition.

8. When prompted to reboot the notebook, press Ctrl+Alt+Del and follow any instructions that appear.

Note

Windows XP supports the NTFS file system.
