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 on the taskbar (if present), 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.
• The notebook’s sound may not operate properly in MS-DOS mode.
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 32.
If you hear a loud high-pitched whine (feedback) from the speakers
• In Volume Control, try reducing the master volume.
• In Volume Control, click Options, Properties, and select the microphone option for the playback
settings. Make sure the microphone is muted.
• Avoid using the built-in microphone and built-in speakers at the same time.
zt1100/xz100 and xt1000 Series Troubleshooting and Diagnostics 15
Troubleshooting and Self-Repair Guide
CD and DVD Problems
If you can’t boot fro m a CD in the CD/DVD driv e
• Make sure the CD is bootable, such as a Re covery C D.
• Make sure the CD-ROM/DVD drive is selected as the boot device—see “Changing the Boot
Device” on page 11.
• Restart the notebook.
• Test the CD/DVD drive with the e-Diagtools diagnostics— see “Using the e-Diagtools Diagnostic
Tests” on page 32.
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 may 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 the notebook.
If a DVD movie stops playing in the middle
• You may have accidentally paused the DVD movie. Press the Play button to resume.
• The DVD may be double-sided. Open the DVD tray, and read the text near the center 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 have regional codes embedded in their 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) to allow you to set the proper region code for your area. Please note
that when you reach this limit, your last change to the region code will be hard-coded on the DVD
drive, and will be permanent. The HP warranty does not cover the expense of correcting this
situation.
Refer to the help for the 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 with a soft cloth.
• 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, try using a different media brand. For best results use
HP certified media. While other media may work, HP cannot guarantee compatibility.
16 Troubleshooting and Diagnostics zt1100/xz100 and xt1000 Series
Troubleshooting and Self-Repair Guide
If a DVD movie doesn’t fill the screen
• Each side of a double-sided DVD has a different format (standard or widescreen). In widescreen
format, black bands appear at the top and bottom of the screen. To view the standard format, flip
the disk over and play the other side.
If you have problems with display r esolution or color depth while playing a DVD
• Set the display resolution and color depth before starting the DVD player. You cannot change
these once the DVD player is started.
• Some combinations of color depth and resolution are not supported in DVD playback. If needed,
reduce color depth or display resolution.
If a DVD doesn’t play with two displays
• Before starting the DVD player, press Fn+F5 to switch to one display. You cannot switch displays
once the DVD player is started.
• If you’re using both displays, the DVD image will not appear on any display set up as
“secondary”. Click Start, Control Panel, Appearance and Themes, Display. Click Advanced on
the Settings tab, then click the S3Display tab and change settings.
Display Problems
If the notebook is on, but the screen is blank
• Move the mouse or tap the touch pad or scroll pad. This will wake the display if it is off.
• Try pressing Fn+F2 to increase the display brightness.
• Press Fn+F5 in case the internal display was disabled. (Do this three times to return to the state
you started from.)
• If the notebook is cold, allow it to warm up.
If the screen is difficult to read
• Try setting the display resolution to its default setting of 1024×768: click Start, Control Panel,
Appearance and Themes, Display, Settings.
If part of the Windows desktop is not vi sible and you have to scroll down to see the
taskbar, or does not fill the entire display and has a black border
• The display resolution may be set incorrectly. Adjust as needed.
If an external display does not work
• Check the connections.
• Press Fn+F5 in case the external monitor was disabled. (Do this three times to return to the state
you started from.)
• Test the display with the e-DiagTools diagnostics— see “Using the e-Diagtools Diagnostic Tests”
on page 32.
