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 Guide3–5
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.

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.”

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.
5–4Maintenance 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.

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”).

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.
