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 deferences 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, IB.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.

Using the CD or DVD Player (selected models)

The multimedia buttons on the front of the notebook control the CD/DVD player, and work in much

the same way as do the controls of a standalone CD or DVD player. The player operates whether the

notebook is on, off, on standby, or in hibernation. (When the notebook is on, the volume control

buttons also govern the volume for most audio applications.)

If the notebook is off, on standby, or in hibernation, slide the multimedia power switch to the left to

activate the player. For details about using the CD/DVD player, see the notebook’s Reference Guide.

If you are installing a new hard disk drive, install the factory software and operating system on the

drive before loading any additional software—see “Recovering and Reinstalling Software,” below.

Recovering and Reinstalling Software

Use the Recovery CDs to reinstall the original factory software and operating system. The Recovery

CDs also provide all HP notebook–specific Windows drivers, which are available in the following

locations:

•

On the hard drive, under c:\hp\drivers.

On the Recovery CDs, under \hp\drivers.

On the HP Business Support web site (www.hp.com/go/bizsupport). This web site contains the

latest updates of software drivers for various operating systems.

To recover the factory software installation

The following procedure describes how to recover the notebook’s original software and operating

system. This process can take up to 15 minutes to complete. (For more information about recovering

the factory software installation, see the file readme.txt in the root directory of the Recovery CDs.)

Caution

Be sure to back up the hard disk before proceeding. This procedure formats the hard disk, which

erases all data on the disk. After formatting, you must reinstall any applications.

Do not interrupt the following process or unplug the AC adapter until the process is complete.

1. Back up all data from the hard disk.

2. Connect the AC adapter to the notebook. This is necessary to provide an uninterrupted power

source: the notebook’s battery alone is not adequate.

3. Insert Recovery CD disk 1 into the notebook’s CD/DVD 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.

5. When the HP logo appears, press Esc to display the Boot menu.

6. Use the arrow keys to select the CD/DVD drive as the first boot device, then press Enter.

7. When the Recovery CD dialog box appears, follow the displayed instructions. If prompted, accept

the recommended partition size.

To create the Utility partition without installing the factory software, click Advanced and select not

to install the operating system.

If the 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. When prompted to reboot the notebook, press Ctrl+Alt+Del and follow any instructions that

appear.

Note

Windows XP supports the NTFS file system.

Checking for Customer Abuse

Some units may appear to have been damaged by customer abuse. Use these guidelines to help

determine if this is the case:

•

If the shipping box is seriously damaged, customer abuse cannot be declared.

If the damage could have a cause other than customer abuse, customer abuse cannot be declared.

If the unit shows any of the following, customer abuse is declared:

Missing parts.

Broken plastic parts.

Parts not original to the unit.

Damaged or missing keys on the keyboard.

Table 3-2 on page 3-5 includes additional criteria for determining customer abuse to specific parts of

the unit.

Important

Parts damaged by customer abuse are not covered by the warranty.

Troubleshooting the Problem

Record pertinent information about the notebook:

•

Model and serial number.

Operating system and version.

Software version (hidden file c:\version.inf).

BIOS version.

Accessories and peripherals used.

Analyze the problem:

•

Observe Symptoms. Using the customer’s information, try to duplicate the problem. Determine

how the problem differs from proper behavior. Also, note the functions that do work properly.

•

Separate Problems. If there is more than one symptom, separate them into distinct problems.

Consider Causes. Keep in mind possible causes for each problem. Use the diagnostic tools and

troubleshooting suggestions to help find the possible causes.

The e-Diagtools diagnostic program tests most of the notebook’s components using automatic

and interactive tests, and will be your primary troubleshooting tool. Other tools include the

power-on self-test, the BIOS configuration utility, and the Sycard PCCtest. Table 3-1 on

page 3-5 shows how you can use these tools to isolate the cause of the notebook’s problem.

The troubleshooting suggestions on page 3-5 include general suggestions for repairing units

that show specific failure symptoms.

Swapping modules that may be defective with others known to be good is generally an ideal way to

find the module responsible for the problem. A failure symptom is rarely caused by more than one

module, so you will not usually need to replace more than one to correct a particular failure.

After you replace a module, the notebook will normally be in a confused state and lock up when you

apply power. If this happens, press the reset switch: this resets the notebook, so that you can restart it

in a known state.

Verifying the Repair

Before returning the repaired notebook to the customer, verify the repair by running the following

tests:

•

e-Diagtools Basic Diagnostic Test. Run the basic test of the e-Diagtools diagnostic program

(page 3-22).

–and–

Function Tests. Run tests that check the repaired function, such as in the e-Diagtools diagnostic

program (page 3-22).

–and–

Failed Tests. Run any other tests that failed during troubleshooting.

Diagnostic Tools

This section describes the following diagnostic tools you can use for troubleshooting and repairing the

notebook:

•

e-Diagtools diagnostic program (below).

Power-on self-test (page 3-25).

Sycard PCCtest 450 PC Card (page 3-26).

BIOS configuration utility (page 3-27).

e-Diagtools Diagnostic Program

The e-Diagtools hardware diagnostic program provides two levels of testing:

•

Basic user-level hardware test.

Advanced individual hardware tests.

Figure 3-2. e-Diagtools Screens — Basic and Advanced

The tests are designed to run after the system restarts, so that the notebook will be in a predictable

state during the tests. The tests are non-destructive, and are intended to preserve the state of the

notebook. The notebook restarts when you exit the program so drivers can be loaded.

Updating e-Diagtools

You can download the latest version of e-Diagtools from the HP Notebook web site (see page vi).

Follow the instructions included with the new version.

4. The first time you run the program, you are prompted to select the language for the program.

5. Press F2 to proceed with the basic tests.

You can also proceed directly to the advanced tests from this point by pressing Ctrl-F9 (in which

case skip to step 10, below).

6. When the hardware detection finishes, check the list of detected hardware.

Note

If a device is not detected or fails its test, it might be configured incorrectly in BIOS. You can

confirm this by running the BIOS configuration utility and checking the settings—see “BIOS

Configuration Utility” on page 3-27.

7. Run the basic test. Press F2 to start the basic hardware test.

If the basic test fails, you can press F6 and start a Wizard that runs a set of advanced tests for the

failed component. Then generate a support ticket.

8. To exit without running the advanced tests, press F4 to view the Support Ticket. Press F3 to exit.

9. Optional: Run the advanced tests. Press F2 to open the advanced test screen.

Power-On Self-Test

The POST (Power-On Self-Test) is a series of initialization routines and diagnostic tests that the

system BIOS runs when the notebook boots. The system BIOS will not boot the operating system if

system memory, the CPU, DMA, or interrupt controller fails the POST diagnostic tests. POST

progress is indicated by a sequence of codes, and error messages are displayed if possible.

You should not necessarily interpret the failure of one or more POST tests as a hardware, software, or

firmware failure. If an error message appears, confirm the problem using other diagnostic tools. Not

all POST messages indicate a hardware, software, or firmware failure—some messages are for

information only.

First, confirm the failure by performing a “clean” boot, as described below: If the notebook fails to

restart with a clean boot, it requires repair.

1. Remove all accessories, including SDRAM modules, PC cards, printer, external monitor, pointing

device, and keyboard.

2. Provide “clean” AC power—no auto adapter or unusual AC adapter configuration.

3. Press the reset switch to return the notebook to a known state.

If the BIOS detects a terminal error condition, it halts POST after issuing a terminal error beep code

Sycard PCCtest 450/460 CardBus Card (Optional)

The PCCtest 450 and 460 CardBus Cards (version 1.05) available from Sycard Technology are the

only recommended diagnostic tool that tests the functionality of the PCMCIA slots using a PCMCIA

card. Each is a Type II PC Card that works with compatible test software to exercise PCMCIA

functions. (For details, see the Sycard Technology Web site: http://www.sycard.com.)

The PCCtest product contains these components:

•

PCCtest 450 or 460 (revision 1.05) PC Card.

PCCtest 450/460 test software disk. (Software updates are available at the Sycard Technology

web site: http://www.sycard.com.)

•

Configuration headers (PC Card/16-bit and CardBus/32-bit) that attach to the card.

You will also need a CardBus extender card (such as the Sycard PCCextend 70) to avoid wear on the

Sycard PCMCIA connector.

The Sycard PCCtest 450 and 460 provide the following tests. See the Sycard documentation for

details about running the tests.

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.

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 work-

around 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.
