Software Updates

To stay current with the newest technology and maintain optimal performance, install the latest versions of HP software on your computer as they become available.
To update HP software:
1. Identify your computer model, product category, and series or family. Prepare for a system BIOS update by identifying the BIOS version currently installed on the computer.
CAUTION: If your computer is connected to a network, it is
Ä
recommended that you consult with your network administrator before installing any software updates, especially system BIOS updates.
3
Recovery
The computer system BIOS is stored on the system ROM. The
BIOS initializes the operating system, determines how the computer will interact with the hardware devices, and provides for data transfer among hardware devices, including the time and date.
2. Access the updates through the HP Web site (
http://www.hp.com) or the Support Software disc (purchased
separately).
3. Install the updates.
Maintenance and Service Guide 3–1
Software Update and Recovery

Accessing Computer Information

Before you access the updates for your computer, collect the following information:
The product category is tablet PC.
The product family name and series number are printed on
the display bezel.
Model information is provided on the serial number label on
the bottom of the computer.
To determine whether available BIOS updates contain later BIOS versions than those currently installed on the computer, you need to know the version of the system BIOS currently installed.
BIOS version information (also known as ROM date and System BIOS) can be displayed by pressing Microsoft Windows) or by opening Computer Setup.
To use Computer Setup for displaying BIOS information:
1. Open Computer Setup by turning on or restarting the computer, and then pressing Based Setup” message is displayed in the lower-left corner of the screen.

3–2 Maintenance and Service Guide
Software Update and Recovery

Obtaining the Support Software Disc

The Support Software disc provides HP software updates and installation instructions. The disc includes device drivers, BIOS updates, and utilities.
To purchase the current Support Software disc or a subscription that provides both the current version and future versions of the disc, visit the HP Web site at
http://www.hp.com.

Software Updates and the HP Web Site

Most software on the HP Web site is packaged in a compressed file called a SoftPaq. Some BIOS updates may be packaged in a compressed file called a ROMPaq.
Most download packages contain a file named Readme.txt. A Readme.txt file contains information regarding installing and troubleshooting the file. The Readme.txt files included with ROMPaqs are provided in English only.

Downloading a BIOS Update

CAUTION: To prevent damage to the computer or an unsuccessful
Ä
installation, download and install a BIOS update only when the computer is connected to reliable external power using the AC adapter. Do not download or install a BIOS update while the computer is running on battery power, docked in an optional docking device, or connected to an optional power source. During the download and installation:
Do not disconnect power from the computer by unplugging the
power cord from the AC outlet.
Do not shut down the computer or initiate standby or hibernation.
Do not insert, remove, connect, or disconnect any device, cable,
or cord.
Maintenance and Service Guide 3–3
Software Update and Recovery
To download a BIOS update:
1. Access the page on the HP Web site that provides software for your computer:
Select Start > Help and Support, and then click a
software update link.
– or –
Visit the HP Web site at http://www.hp.com/support.
2. Follow the instructions on the screen to identify your computer and access the BIOS update you want to download.
3. At the download area:
a. Identify the BIOS update that is later than the BIOS
version currently installed on your computer. Make a note of the date, name, or other identifier. You may need this information to locate the update later, after it has been downloaded to your hard drive.
b. Follow the instructions on the screen to download your
selection to the hard drive.
Make a note of the path to the location on your hard drive
where the BIOS update will be downloaded. You will need to access this path when you are ready to install the update.

Installing a BIOS Update

CAUTION: If your computer is connected to a network, it is
Ä
recommended that you consult with your network administrator before installing any software updates, especially system BIOS updates.
BIOS installation procedures vary. Follow any instructions that are displayed on the screen after the download is complete. If no instructions are displayed:
1. Open Windows Explorer by selecting Start > All Programs > Accessories > Windows Explorer.
3–4 Maintenance and Service Guide
2. In the left pane of the Windows Explorer window:
a. Click My Computer and then your hard drive
designation. The hard drive designation is typically Local Disk (C:).
b. Using the hard drive path you recorded earlier, open the
folder on your hard drive that contains the update.
3. Double-click the file with an .exe extension (for example, filename.exe).
The BIOS installation begins.
4. Complete the installation by following the instructions on the screen.
After a message on the screen reports a successful installation,
you may delete the downloaded file from your hard drive.

Recovering the BIOS

The BIOS recovery procedure requires a USB diskette drive
and a formatted diskette.
Software Update and Recovery
The BIOS can be recovered if the flash memory is corrupted. Flash memory corruption can occur if the notebook powers down while the BIOS is being updated.
When the notebook is turned on, the boot block portion of the flash memory performs an integrity check on the rest of the BIOS image and enters recovery mode if the image is corrupt.
BIOS recovery can be forced on a non-functioning notebook by turning on the notebook while pressing and holding the Windows logo key + caps lock light blinks.
Maintenance and Service Guide 3–5
B on the nonfunctioning notebook keyboard until the
Software Update and Recovery
To recover the BIOS:
1. If the nonfunctioning notebook is docked in an optional docking device, undock the notebook.
2. Attach the USB diskette drive directly to a USB port on the nonfunctioning notebook. (USB hubs are not supported for BIOS recovery).
3. Insert the correct ROMPaq diskette for the product being updated. The BIOS image file must be located in the root directory of the diskette and must be in contiguous sectors. The easiest way to ensure this is to visit download the Softpaq, and let the Softpaq create the ROMPaq diskette.
http://www.hp.com,
4. Press and hold the Windows logo key +
B on the notebook
keyboard (do not use an external keyboard) and turn on the notebook and wait for the caps lock light to start blinking.
5. Release the Windows logo key +
B.
The BIOS recovery procedure takes approximately one minute to read the image from the diskette, and then an additional 15 seconds to program the image into flash memory. The notebook restarts when the BIOS recovery procedure is complete. Do not attempt to turn off the notebook after starting a recovery.
If the BIOS recovery procedure stalls, the caps lock light will begin blinking. This situation can arise if the diskette is corrupt or the incorrect ROMPaq is used. If the notebook does not restart after approximately 3 minutes, press and hold the power button, or slide and hold the power switch, for at least 5 seconds to force the notebook to turn itself off. Then repeat the BIOS recovery procedure.

Removal and Replacement Preliminaries

5.2 Service Considerations

The following sections include some of the considerations that you should keep in mind during disassembly and assembly procedures.
As you remove each subassembly from the tablet PC, place
the subassembly (and all accompanying screws) away from the work area to prevent damage.

Plastic Parts

Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions.

Cables and Connectors

CAUTION: When servicing the tablet PC, ensure that cables are
Ä
placed in their proper locations during the reassembly process. Improper cable placement can damage the tablet PC.
Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Ensure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables tear easily.
5–2 Maintenance and Service Guide
Removal and Replacement Preliminaries

5.3 Preventing Damage to Removable Drives

Removable drives are fragile components that must be handled with care. To prevent damage to the tablet PC, damage to a removable drive, or loss of information, observe the following precautions:
Before removing or inserting a hard drive, shut down the
tablet PC. If you are unsure whether the tablet PC is off or in hibernation, turn the tablet PC on, and then shut it down through the operating system.
Before removing a diskette drive or optical drive, ensure that
a diskette or disc is not in the drive and ensure that the optical drive tray is closed.
Before handling a drive, ensure that you are discharged of
static electricity. While handling a drive, avoid touching the connector.
Handle drives on surfaces covered with at least one inch of
shock-proof foam.
Avoid dropping drives from any height onto any surface.
After removing a hard drive, an optical drive, or a diskette
drive, place it in a static-proof bag.
Avoid exposing a hard drive to products that have magnetic
fields, such as monitors or speakers.
Avoid exposing a drive to temperature extremes or liquids.
If a drive must be mailed, place the drive in a bubble pack
mailer or other suitable form of protective packaging and label the package “FRAGILE: Handle With Care.”
Maintenance and Service Guide 5–3
Removal and Replacement Preliminaries

5.4 Preventing Electrostatic Damage

Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.
A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs.
An electronic device exposed to electrostatic discharge may not be affected at all and can work perfectly throughout a normal cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life expectancy.
5–4 Maintenance and Service Guide
Removal and Replacement Preliminaries

5.5 Packaging and Transporting Precautions

Use the following grounding precautions when packaging and transporting equipment:
To avoid hand contact, transport products in static-safe
containers, such as tubes, bags, or boxes.
Protect all electrostatic-sensitive parts and assemblies with
conductive or approved containers or packaging.
Keep electrostatic-sensitive parts in their containers until
the parts arrive at static-free workstations.
Place items on a grounded surface before removing items
from their containers.
Always be properly grounded when touching a sensitive
component or assembly.
Store reusable electrostatic-sensitive parts from assemblies
in protective packaging or nonconductive foam.
Use transporters and conveyors made of antistatic belts and
roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
Maintenance and Service Guide 5–5
Removal and Replacement Preliminaries

5.6 Workstation Precautions

Use the following grounding precautions at workstations:
Cover the workstation with approved static-shielding material
(refer to
Use a wrist strap connected to a properly grounded work
surface and use properly grounded tools and equipment.
Use conductive field service tools such as cutters, drivers, and
vacuums.
When fixtures must directly contact dissipative surfaces, use
fixtures made only of static-safe materials.
Keep the work area free of nonconductive materials such
as ordinary plastic assembly aids and Styrofoam.
Handle electrostatic-sensitive components, parts, and
assemblies by the case or PCM laminate. Handle these items only at static-free workstations.
Avoid contact with pins, leads, or circuitry.
Turn off power and input signals before inserting or removing
connectors or test equipment.
Table 5-2, “Static-Shielding Materials”).
5–6 Maintenance and Service Guide
Removal and Replacement Preliminaries

5.7 Grounding Equipment and Methods

Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
When seated, wear a wrist strap connected to a grounded
system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap.
When standing, use foot straps and a grounded floor mat.
Foot straps (heel, toe, or boot straps) can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resistance between the operator and ground. To be effective, the conductive strips must be worn in contact with the skin.
Other grounding equipment recommended for use in preventing electrostatic damage includes
Antistatic tape.
Antistatic smocks, aprons, and sleeve protectors.
Conductive bins and other assembly or soldering aids.
Nonconductive foam.
Conductive tabletop workstations with ground cords of
one megohm resistance.
Static-dissipative tables or floor mats with hard ties to
the ground.
Field service kits.
Static awareness labels.
Material-handling packages.
Nonconductive plastic bags, tubes, or boxes.
Metal tote boxes.
Electrostatic voltage levels and protective materials.
