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 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 audible
• Press Fn+Page Up several times.
• Click the speaker icon in the taskbar (if present), and make sure Mute is not checked and the
Volume slider is not set to the bottom.
• Double-click the speaker icon in the taskbar and make sure the audio source is not muted. If the
source is not displayed, click Options, Properties, and select the source from the volume control
list.
If sound does not record
• Make sure the microphone is securely connected to the microphone jack.
• Check the software controls for recording sound: click Start, All Programs, Accessories,
Multimedia (or Entertainment), Sound Recorder.
• Double-click the speaker symbol in the taskbar. Then 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 29.
If the PC Card detection beep(s) at startup are very loud and volume cannot be adjusted
• Download the latest audio driver from the technical support area of the HP notebook Web site
(www.hp.com/notebooks).
If you hear a loud high-pitched whine (feedback) from the speakers
• Double-click the speaker symbol in the taskbar, and try reducing the master volume.

14 Troubleshooting and Diagnostics ze1000 Series Troubleshooting and Self-Repair Guide
CD and DVD Problems
If you can’t boot from a CD in the DVD/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 11.
• Restart the notebook.
• Test the DVD/CD-RW drive with the e-DiagTools diagnostics—see “Using the e-DiagTools
Diagnostic Tests”on page 29.
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 playing 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 CD or DVD
• Make sure the disk is properly inserted, and snapped down onto the spindle in the center of the
tray.
• 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 module, try using a different media brand. For best
results use HP certified media. While other media may work, HP cannot guarantee compatibility.

ze1000 Series Troubleshooting and Self-Repair Guide Troubleshooting and Diagnostics 15
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 a DVD doesn’t play with two displays
• If both displays are active, 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. 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 of 1024×768: click Start, Control Panel,
Appearance and Themes, Display, Settings.
• Try adjusting the size of the desktop icons and labels.
If part of the Windows desktop is not visible and you have to scroll down to see the
taskbar, or if the desktop does not fill the entire display and has a black border
• Your display resolution may be set incorrectly. Adjust the resolution 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 29.

16 Troubleshooting and Diagnostics ze1000 Series Troubleshooting and Self-Repair Guide
If one or more display pixels look bad
TFT display manufacturing is a highly precise but imperfect technology, and manufacturers cannot
produce displays that are cosmetically perfect. Most, if not all, TFT displays exhibit some level of
cosmetic imperfection. These cosmetic imperfections may be visible under varying display conditions,
and can appear as bright, dim, or dark spots. This issue is common across all vendors supplying TFT
displays in their products and is not specific to the HP notebook display.
HP notebook TFT displays meet or exceed all HP standards for cosmetic quality of TFT displays. HP
does not warrant that the displays will be free of cosmetic imperfections. TFT displays can have a
small number of cosmetic imperfections and still conform to HP’s cosmetic quality specifications,
including the following:
• No more than 6 pixels remain on (always one color, such as white, red, green, or blue dots).
• No more than 6 pixels remain off (always dark).
• No more than a total of 8 pixels stuck on or off.
• No other stuck pixel within 15 mm of a stuck pixel.
Contact HP Customer Care if you have a display quality problem and require a more comprehensive
explanation of HP display quality. We expect that over time the industry will continue to produce
displays with fewer inherent cosmetic imperfections, and we will adjust our HP guidelines as these
improvements are implemented.
Floppy Disk Drive Problems
If a floppy drive connected to the USB port doesn’t work
• Make sure the drive is securely connected to the notebook.
• Restart the notebook: click Start, Turn Off Computer, Restart.
Hard Disk Drive Problems
If the notebook’s hard drive doesn’t spin
• Make sure the notebook has power. If necessary, connect the AC adapter, and make sure it is fully
plugged into a power source and into the back of the notebook.
If the hard disk makes a buzzing or whining noise
• Back up the drive immediately.
• See whether the noise is coming from elsewhere, such as the fan or floppy disk drive.
If files are corrupted
• Check the hard disk: open My Computer, select the disk you want to scan, click File, Properties,
and use the Tools tab.
• Run the Norton AntiVirus program.
• Test the hard disk drive with the e-DiagTools diagnostics—see “Using the e-DiagTools
Diagnostic Tests”on page 29.
• If necessary, format the hard disk and reinstall the original factory software—see “Recovering the
Factory Software Installation”on page 33.

ze1000 Series Troubleshooting and Self-Repair Guide Troubleshooting and Diagnostics 17
If the hard drive’s reported capacity is less than its actual size
• The hard disk drive is preconfigured to allocate some space to diagnostic software, which is used
for support and service of your notebook. This part of the hard drive is unavailable for other uses,
and so is not included in the capacity of the hard drive as reported by Windows (My Computer,
Properties).
Heat Problems
Keep in mind that your notebook normally gets warm during routine operation. Charging the battery
and running games and other programs that drive CPU usage toward 100% can further increase the
notebook’s temperature.
If the notebook gets warmer than usual
• Always set the notebook on a firm, flat surface, so that air can flow freely around and underneath
it. Do not place an operating notebook on carpeting, clothing, or other soft surface, as this can
block the fan’s air intake on the bottom of the notebook.
• Provide adequate ventilation around the notebook. Make sure there is adequate clearance at the
back of the notebook, so that its fan vent is not blocked.
• Always turn off the notebook or put it into hibernation before placing it in a carrying case or other
enclosed space.
• Make sure the fan is working properly. If needed, test the fan’s operation—see “Using the
e-DiagTools Diagnostic Tests”on page 29.
Keyboard, Touch Pad, and Mouse Problems
If the touch pad is difficult to control
• Customize the touch pad by modifying Mouse properties: click Start, Control Panel, Printers and
Other Hardware, Mouse.
If the pointing devices don’t work
• Don’t use the touch pad while the notebook is starting up or resuming from standby or
hibernation. If this happens, try the following:
• Press any key on the keyboard.
• Put the notebook on standby, then resume operation.
• Restart the notebook: click Start, Turn Off Computer, Restart.
• Test the keyboard and pointing devices with the e-DiagTools diagnostics—see “Using the
e-DiagTools Diagnostic Tests”on page 29.
If the embedded numeric keypad doesn’t work
• To type numbers, make sure Num Lock is on.
• Make sure the embedded Keypad Lock (Fn+F8) is on—or that you press and hold the Fn key to
temporarily access the embedded keypad.

18 Troubleshooting and Diagnostics ze1000 Series Troubleshooting and Self-Repair Guide
If a special feature on a USB mouse doesn’t work
• Make sure you installed any drivers included with the mouse.
• Restart the notebook, so that it will detect the mouse.
LAN Problems
If the built-in network adapter doesn’t connect to the LAN
• Check all cables and connections. Try connecting at a different network station, if available.
• If the green light next to the LAN port does not light, the LAN cable may not be connected to the
network or the network may be down. Try connecting a different notebook to the cable.
• Click Start, Control Panel, Network and Internet Connections, Network Connections. Make sure
you have the correct clients and protocols installed.
• Make sure the LAN cable is Category 3, 4, or 5 for 10Base-T operation, or Category 5 for
100Base-TX operation. Maximum cable length is 100 meters (330 feet).
• Use the networking problems troubleshooter in Windows Help and Support.
• Click Start, Control Panel, Performance and Maintenance, System. On the Hardware tab, open the
Device Manager. If the network interface is disabled, try to enable it. If it has a conflict, try
disabling another device.
If you can’t browse My Network Places
• Click Start, Search to look for a computer.
• Check with your network administrator to make sure NetBEUI protocol is supported on the
network.
If you can’t log in to Netware servers
• If a Netware server is using IPX/SPX protocol, you may need to force your frame type to match
the server’s frame type. Check with your network administrator.
If the notebook stops responding after booting
• Check whether you have a TCP/IP network with no DHCP server. This can cause a long delay at
startup because DHCP is enabled. Contact your network administrator to determine the proper
TCP/IP configuration.
If file transfers are unusually slow or produce timeout errors
• Connect the AC adapter.

ze1000 Series Troubleshooting and Self-Repair Guide Troubleshooting and Diagnostics 19
Memory Problems
If a message says you are out of memory
• Make sure drive C is not running low on free space.
• Use the memory troubleshooter in Windows Help and Support.
• If you are having memory problems while running MS-DOS programs, use the application and
software problems troubleshooter in Windows Help and Support.
• Not all third-party memory cards have been tested for use with the notebook. Check the HP
Notebook Web site (www.hp.com/notebooks) for a list of approved and tested memory cards.
• Test your notebook’s memory with the e-DiagTools diagnostics—see “Using the e-DiagTools
Diagnostic Tests”on page 29.
If memory doesn’t increase after adding RAM
• Make sure all RAM modules are installed properly.
• Test your notebook’s memory with the e-DiagTools diagnostics—see “Using the e-DiagTools
Diagnostic Tests”on page 29.
If the notebook will not boot up after adding RAM
• Make sure your notebook is using only PC133 SDRAM modules, or it will not boot up. (You will
also see an error message.)
Modem Problems
If the modem seems slow
• Check for excess static or noise on the line, which reduces the overall transmission speed. If
necessary, contact your telephone company about fixing this type of problem.
• If you’re dialing internationally, line noise is often difficult or impossible to eliminate.
• If you have call-waiting, disable it—see Windows Help and Support, and contact your telephone
company for information.
• Eliminate extra connections in the line. If possible, connect directly to the wall jack.
• Try another telephone line, preferably one normally used for a fax machine or modem.
If the modem doesn’t dial or no dial tone is detected
• Check all cables and connections.
• Connect a standard telephone to the phone line and make sure the line is working.
• Make sure someone else isn’t using the same phone line.
• Try another telephone line, preferably one normally used for a fax machine or modem.
• If you’re in a foreign country/region, the dial tone may not be recognized by the modem. Click
Start, Control Panel, Printers and Other Hardware, Phone and Modem Options. Select your
modem on the Modems tab, then click Properties, Modem, and disable the option that waits for a
dial tone.
