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.
zt1000/xz300 and xt1500 Series Troubleshooting and Diagnostics 17
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 a DVD doesn’t play with two displays
• If both displays are active, press Fn+F5 to switch to one display.
• 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 Displays tab and change settings.
Display Problems
If the notebook does not recognize the display
When the notebook starts up, it automatically re-activates the display that was in use when Windows
was last shut down. If you dock to a simple port replicator or attach a monitor while the notebook is
off, the notebook may not properly recognize the monitor. If this happens, choose the display that you
want to use in either of these ways:
• Press Fn+F5. (Do this three times to return to the state you started from.)
• Click Start, Control Panel, Appearance and Themes, Display, Settings, and then click the
Advanced button. On the Displays tab, select the Display Device you want, and then click OK.
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 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 vi sible 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.)
• If you’re using a TV connected to the S-video port, you must activate the TV.
18 Troubleshooting and Diagnostics zt1000/xz300 and xt1500 Series
Troubleshooting and Self-Repair Guide
• Test the display with the e-DiagTools diagnostics— see “Using the e-DiagTools Diagnostic
Tests” on page 31.
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.
• Remove and reinsert the hard drive—see “Removing the Hard Disk Drive” on page 40.
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 a PC Card drive.

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—your telephone company can provide instructions.
• 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.
• Many countries impose a blackout period after a modem repeatedly fails to connect to a service
provider. The number of failed attempts and the period you must wait before trying again differ
from country/region to country/region: check with your telephone company.
For example, if you are dialing from Italy and fail to connect to your server or cancel the
connection, you must wait one minute before dialing that number again. If you dial before then,
you will get an error message that says “delay.” After the fourth failed connection, you must wait
one hour before trying the number again. If you dial before the hour is up, you will get a message
that says “black list.”

• Try conserving power using any of the suggestions listed in the online Reference Guide.
• If you are running an application that has an automatic save feature (such as MS Word), disable
this feature or increase the specified save time to reduce hard disk access.
• If the operating time has gradually become shorter and the battery is more than a year or two old,
you may need to replace the battery.
• Heavy modem use can affect battery operating time.
zt1000/xz300 and xt1500 Series Troubleshooting and Diagnostics 27
Troubleshooting and Self-Repair Guide
• PC Card use can affect battery operating time.
If the Time Remaining for the battery seems incorrect
• The Time Remaining is an estimate based on the rate at which the notebook is using power at that
instant. So, if you check the Time Remaining while the notebook is using a good deal of power
(such as when reading from a CD or DVD), the value will likely show less time remaining than
you really have, since you will probably later switch to tasks that require less power.
If the notebook doesn’t go on sta nd by as expected
• If you have a connection to another computer, the notebook won’t go on standby if the connection
is active.
• If the notebook is performing an operation, it normally waits for the operation to finish before
going on standby.

hard disk. You can also use the same process to create a larger Utility partition on your hard disk, or to
create a Utility partition on a new hard disk. The hidden Utility partition contains the e-DiagTools
diagnostic tests and stores hibernation data for operating systems that don’t provide hibernation.
CAUTION
This procedure formats the notebook’s hard disk drive and erases all data on the disk. After the
hard disk is formatted, you’ll need to reinstall your applications.
Do not interrupt the following process or unplug the AC adapter until the process is complete.
1. Important: back up all data from your hard disk. The following steps delete all data from the
disk.
2. Connect the AC adapter to the notebook.
3. Insert the Recovery CD (disk 1) or DVD into the notebook’s DVD/CD-RW 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. If the notebook is running, click Start, Turn Off Computer,
Restart.
5. When the HP logo appears, press Esc to display the Boot menu.
6. Use the arrow keys to select the DVD/CD-RW drive as the boot device, and press Enter.
7. When the Rec overy C D or DVD dialog box appears, follow the displayed instructions. If
prompted, accept the recommended partition size. If you install the factory software, the recovery
process can take up to 15 minutes.
If you want to create the Utility partition without installing the factory software, click Advanced
and select not to install the operating system.
If your 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. Important: when prompted to reboot the notebook, press Ctrl+Alt+Del and follow any
instructions that appear.

Troubleshooting and Self-Repair Guide
Reference Information
This section includes information on HP’s password removal policy, and on notebook display quality.
Password Removal Policy
If the user forgets the system password, the user calls HP Customer Care to determine the proper
password removal procedure. The user must provide proof of ownership, and the notebook must be
operated during the procedure.
The password removal procedure is protected as HP Company Private information. There are a
restricted number of locations that can perform password removal. The procedure may not be
disclosed or distributed outside those locations.
Password removal is strictly controlled. Hewlett-Packard and authorized support providers must
ensure with written evidence that the notebook being “cleansed” is actually in the possession of the
notebook’s actual and current owner. This requires a sales receipt showing the notebook serial number
and owner’s name, or a written statement from the owner attesting that he or she is the owner of the
notebook. The statement can be a fax copy of the document. The fact that the notebook is in the hands
of an HP representative on behalf of the customer is not evidence of ownership. In addition, HP will
not remove the password of a notebook for any non-owner, even if it is requested by law enforcement
agencies. If you receive such a request, you should notify management and HP Corporate Legal
immediately. (These requests may require a court order prior to our participation.)
Further, the entity removing the password must log the name, serial number, and date of the removal,
and file the written backup with the log. The log and backup are subject to standard record retention
process and review.
The final issue relating to removal of passwords is that HP cannot provide information to users that
would assist them in improperly removing a password and opening a notebook.
Hewlett-Packard Display Quality Statement
TFT display manufacturing is a highly precise but imperfect technology, and manufacturers cannot
produce large displays that are cosmetically perfect. Most, if not all, TFT displays exhibit some level
of cosmetic imperfection. These cosmetic imperfections may be visible to the customer 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.
zt1000/xz300 and xt1500 Series Reference Information 55
Troubleshooting and Self-Repair Guide
Here are some guidelines for determining what action to take on customers’ complaints of cosmetic
imperfections in their TFT displays:
1. View the notebook under the customer’s normal operating conditions.
This means that if the customer uses the notebook predominately in DOS, in Windows, or in some
other application or combination of applications, you should make the determination under those
same applications. Self test is not a normal operating condition and is not a sufficient tool for
interpreting display quality.
2. Use the table below to determine whether the display should be considered for replacement. These
are the only conditions in this guideline that may call for a replacement due to a defect in material
or workmanship based on the HP Limited Warranty Statement.
3. If a display is considered for replacement, make sure the customer understands that cosmetic
variations may also exist on the replacement display, and may require the customer to use a workaround to obscure the cosmetic imperfection.
4. Displays with cosmetic imperfections that do not conform to the above conditions and tests will
not normally be considered for display replacement. The HP-responsible person working with the
customer should identify work-arounds that are reasonable and appropriate for that customer.
Customers who require a more perfect display solution should consider switching to a notebook
with a DSTN display.
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.
Type of Imperfection Imperfections Not Allowed
Electrical Imperfections:
Bright dots
Dark dots
(a)
(a)
• 7 or more single bright dots.
