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 differences 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, IC.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.

Troubleshooting and Self-Repair Guide
Troubleshooting and Diagnostics
This section contains solutions to several types of problems you may encounter when using the
notebook. Try the solutions one at a time, in the order in which they are presented.
You can also find technical tips and software updates for the notebook at the HP Business Support
Web site (www.hp.com/go/bizsupport).
Audio Problems
If no sound is audibl e
• Press Fn+Page Up several times.
• If available, press the rear volume control several times.
• Click the speaker icon in the taskbar, and make sure Mute is not checked and the Volume slider is
not set to the bottom.
• If available, press the mute button on the right side of the notebook once or twice until the
indicator light goes off.
If sound does not rec ord
• Check the software controls for recording sound: click Start, All Programs, Accessories,
Entertainment, Sound Recorder.
• In Volume Control, click Options, Properties, and make sure the microphone is enabled in the
recording controls.
• Test the audio with the e-DiagTools diagnostics— see “Using the e-DiagTools Diagnostic Tests”
on page 31.
If you hear a loud high-pitched whine (feedback) from the spea kers
• In Volume Control, try reducing the master volume.
• In Volume Control, click Options, Properties, and select the microphone option for the playback
settings. Then in Volume Control, make sure the microphone is muted.
• Avoid using the built-in microphone and built-in speakers at the same time.
16 Troubleshooting and Diagnostics zt1000/xz300 and xt1500 Series
Troubleshooting and Self-Repair Guide
CD and DVD Problems
If you can’t boot fro m a C D i n t he D VD/CD-RW drive
• Make sure the CD is bootable, such as the Recovery CDs.
• Make sure the DVD/CD-RW drive is selected as the boot device—see “Changing the Boot
Device” on page 13.
• Restart the notebook.
• Test the DVD/CD-RW drive with the e-DiagTools diagnostics— see “Using the e-DiagTools
Diagnostic Tests” on page 31.
If a CD or DVD plays erratically
• Dirt or smudges can cause a disk to skip. Clean the disk with a soft cloth. If the disk is badly
scratched, it will probably have to be replaced.
• Some DVDs include software called “PC Friendly.” You generally should not install this
software, as it can cause errors or erratic play. If needed, uninstall it and restart your notebook.
If a DVD movie stops playing in the middle
• You may have accidentally paused the DVD movie. Press the Play button to continue.
• The DVD may be double-sided. Open the DVD tray and read the text near the center hole of the
disk. If it says Side A, flip the disk over, close the tray, and press the Play button to continue
playing the movie.
If you get a Region Code error when pl aying a DVD movie
• DVDs can have regional codes embedded in the disk data. These codes prevent DVD movies
from being played outside the region of the world in which they are sold. If you get a Region
Code error, you are trying to play a DVD intended for a different region.
Important: most DVD drives let you change the region code only a limited number of times
(usually no more than four). When you reach this limit, your last change to the region code will be
hard-coded on the DVD drive, and will be permanent. Your HP warranty does not cover the
expense of correcting this situation.
Refer to the help for your DVD player software for details about setting region codes.
If the notebook cannot read a C D or D V D
• For a single-sided CD or DVD, make sure the disk is placed in the drive with the label facing up.
• Clean the disk.
• Wait 5 to 10 seconds after closing the tray for the notebook to recognize the disk.
• Remove the disk from the drive, then restart the notebook.
• If you created the CD on a CD-RW drive module, try using a different media brand, such as the
recommended HP C4403A (CD-R) or C4404A (CD-RW) media. Read and write quality may vary
for other media.
