Major ICs

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. 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 record

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 speakers
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.

CD and DVD Problems

If you cant 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 devicesee 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 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
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.
If a DVD movie doesnt 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 doesnt play with two displays
If both displays are active, press Fn+F5 to switch to one display. If youre 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.

If the modem dials incorrectly
Check the telephone number you entered, including any digits required for outside access or long distance. In Control Panel, open Phone and Modem Options, and check the dialing optionslook for duplicate digits for outside access or long distance. Make sure the number youre calling isnt busy. If youre 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. If you have call-waiting, disable itsee Windows Help and Support, and contact your telephone company for information.
If the modem dials but doesnt connect
Make sure youre using an analog telephone line. You must not use a digital line. In a hotel, ask for a data line. Try another telephone line, preferably one normally used for a fax machine or modem. The modem at the other end may have a problem. Try dialing to a different modem.
If the modem will not connect at 56K speed
The host modem may not support a 56K (V.90) connection speed. Connection speed depends on several factors, such as the condition of the telephone line. Try connecting another time.
If the modem will not connect at any speed
Make sure youre using an analog telephone line. You must not use a digital line. In a hotel, ask for a data line. Make sure the telephone line goes directly from the notebooks modem phone jack to the telephone jack on the wall. If you have a single telephone line for voice and modem use, make sure no one else is using the line and that the phone is not off the hook. Try another telephone line, preferably one normally used for a fax machine or modem. Contact your Internet Service Provider (ISP). It's possible that service may be unavailable temporarily or that your settings are incorrect. Restart your notebook and attempt another connection. Download the latest modem driver from the technical support area of the HP notebook Web site (www.hp.com/notebooks). Run the modem diagnostics: 1. Click Start, Control Panel, Printers and Other Hardware, Phone and Modem Options. 2. Click the Modems tab, and select the modem you want to test. 3. Click Properties, Diagnostics, Query Modem.
If the modem isnt detected
Check the modem setup. In Control Panel, open Phone and Modem Options. Click Start, Control Panel, Performance and Maintenance, System. On the Hardware tab, open the Device Manager. If the modem is disabled, try to enable it. If it has a conflict, try disabling another device. If youre running fax software using fax Class 2, try using Class 1.

If a USB modem doesnt work properly
See Modem Problems on page 22. Make sure the modem is securely connected to the USB port. Use the modem troubleshooter (under Networking problems) in Windows Help and Support. Check the modem settings in Control Panel. Disable the internal modem: 1. Click Start, Control Panel, Performance and Maintenance, System. On the Hardware tab, open the Device Manager. 2. Double-click Modem to list the current modem devices. 3. Double-click the internal modem, then select the option to disable the modem.
Check the port settings in Control Panel: click Start, Control Panel, Performance and Maintenance, System. On the hardware tab, open the Device Manager, then double-click Universal Serial Bus controllers.
If the parallel port is not working
Make sure the port connection is secure. Check the port settings in Control Panel: click Start, Control Panel, Performance and Maintenance, System. On the Hardware tab, open the Device Manager, and double-click Ports (COM & LPT). Test the ports with the e-DiagTools diagnostics see Using the e-DiagTools Diagnostic Tests on page 31.
If the USB port is not working
Contact the vendor of the peripheral device and check the HP Notebook Web site (www.hp.com/notebooks) for the latest versions of the USB drivers and the driver for the device. Check the port settings in Control Panel: click Start, Control Panel, Performance and Maintenance, System. On the Hardware tab, open the Device Manager, and double-click Universal Serial Bus controllers. Test the USB port with the e-DiagTools diagnostics see Using the e-DiagTools Diagnostic Tests on page 31.
Troubleshooting and Diagnostics 25
PC Card (PCMCIA) Problems
If the notebook doesnt recognize a PC Card
Remove and reinsert the PC Card. Put the notebook on standby, then resume. Restart the notebook. If the card requires an IRQ, make sure one is available. If necessary, set the IRQ to an unused value: click Start, Control Panel, Performance and Maintenance, System. On the Hardware tab, open the Device Manager, then view resources by type. Check the HP Business Support Web site (www.hp.com/go/bizsupport) for information about installing certain PC Cards. Make sure your notebook supports the problem PC Card: check the HP Notebook Web site (www.hp.com/notebooks) for a list of approved and tested PC Cards. Try the card in another computer to see whether the card functions properly. Test the PC Card with the e-DiagTools diagnostics see Using the e-DiagTools Diagnostic Tests on page 31.

If the notebook has a short operating time
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.
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 doesnt go on standby as expected
If you have a connection to another computer, the notebook wont 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.
If the notebook doesnt automatically hibernate as expected
Make sure hibernate support is enabled: click Start, Control Panel, Performance and Maintenance, Power Options, then click the Hibernate tab. Also, check the Power Schemes tab. Make sure the hibernation timeouts for AC power and battery power are not set to Never.

Printing Problems

Hint You can solve most printing problems by using the printing troubleshooter in Windows Help and Support.
If a printer doesnt print
Make sure the printer is on and has paper in it. Make sure you are using the correct printer cable or cable adapter, and that the cable is secure at both ends. Check for printer errors.
If the left edge of the printed output is missing
Certain applications may not work properly with 600-dpi printers. If youre using such a printer, try selecting a compatible printer driver for a 300-dpi printer. For example, if you were using a 600-dpi HP LaserJet printer, you might try using the HP LaserJet IIIsi driver (300 dpi).

Startup Problems

If the notebook doesnt respond when you turn it on
Connect the AC adapter. Reset the notebook by using a pen or straightened paper clip to press the reset switch on the back of the notebook. Then press the power button to turn the notebook on.
Dont use the touch pad while the notebook is starting up or resuming from standby or hibernation. If the notebook still doesnt respond, remove the battery and AC adapter, and remove any PC Card. Then reset the notebook using the reset switch on the back of the notebook, replace the battery and plug in the AC adapter, and turn on the notebook by pressing the power button. If the notebook still doesnt respond, call HP for assistance.

If you can connect, but the network is slow
Check whether you might be in an area served by more than one wireless LAN. If so, the LANs could be interfering with each other. Move closer to the access point (for an infrastructure connection) or other wireless computer (for an ad hoc connection). You could be too far away for high-speed communication. Stop using any USB device that may be transferring large amounts of data, or adjust application settings to reduce the transfer rate.
Using the e-DiagTools Diagnostic Tests

Tested Cross-Platform Accessories

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 customers 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.
