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, GC.M1.02) indicate the hardware technology. You can also determine the BIOS ID using the BIOS Setup Utility, or by pressing ESC during the boot process when the HP logo appears. This manual contains service information for products having the following technology codes.
Technology code GC Product name OmniBook XE3 Pavilion Notebook N5130/50/70/90/95 Details Initial platform technology.

Using the CD-ROM or DVD Player
The multimedia buttons on the front of the notebook control the CD-ROM/DVD player, and work in much the same way as do the controls of a standalone CD-ROM or DVD player. The CD-ROM/DVD player operates whether the notebook is on, off, or in standby or hibernate mode. (When the notebook is on, the volume control buttons also govern the volume for most other audio applications.) If the notebook is off or in standby or hibernate mode, slide the multimedia power switch to the left to activate the player. For details about using the CD-ROM/DVD player, see the notebook's Reference Guide.

Recovering and Reinstalling Software
You can use the Recovery CD to recover an original build or reinstall the HP custom software. To recover a specific application, see "To recover an application" in the Reference Guide. The Recovery CD provides all HP notebook­specific Windows drivers; these drivers are in the following directories: · On the hard drive, under c:\hp\drivers. · On the Recovery CD, under \hp\drivers. · On the HP notebook web site at http://www.hp.com/notebooks. This web site contains the latest software drivers.
To recover the factory software installation

The following procedure describes how to recover the notebook's original Windows software and operating system. This process can take about 10 or 15 minutes. Do not interrupt the process or unplug the AC adapter before the process is complete, or you will have to begin again.

Caution
This procedure formats the hard disk drive, which erases all data on the drive. After formatting, you must reinstall any applications.

1. Back up all data from the hard disk. 2. Connect the AC adapter to the notebook. 3. Insert the Recovery CD in the notebook's CD-ROM drive. 4. Restart the notebook. When the HP logo appears, press F2. 5. Select the CD-ROM drive as the first boot device, then restart the notebook again. You can find more details about recovering the factory installation of Windows on the Recovery CD: the file readme.txt is in the CD's root directory.
Note Windows 98 supports the FAT16 and FAT32 file systems. Windows 2000 supports the FAT16, FAT32, and NTFS file systems.
