Reference Information
This chapter includes the following reference information:
 · Password removal policy.
 · Display quality statement.
Password Removal Policy
If the user forgets the system password, the user calls Technical Support to determine the proper
removal procedure. The user must provide proof of ownership, and the OmniBook 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. It 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 OmniBook being “cleansed” is actually in the possession of the
unit’s actual and current owner.  This requires a sales receipt showing the unit serial number and
owner’s name, or a written statement from the owner attesting that he or she is the owner of the unit.
The statement can be a fax copy of the document.  The fact that the unit 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 unit 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 unit.

Hewlett-Packard Display Quality Statement
TFT display manufacturing is a high precision but imperfect technology and manufacturers cannot
currently produce large displays that are cosmetically perfect.  Most, if not all, TFT displays will
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
OmniBook display.
HP OmniBook TFT displays meet or exceed all TFT manufacturer’s standards for cosmetic quality of
TFT displays.  HP does not warrant that the displays will be free of cosmetic imperfections.  TFT
displays may have a small number of cosmetic imperfections and still conform to the display
manufacturer’s cosmetic quality specifications.
Here are some guidelines to use in determining what action to take on customers’ complaints of
cosmetic imperfections in their TFT displays:
 1. The unit should be viewed in the customer’s normal operating condition.
 This means if the customer uses the unit predominately in DOS, in Windows, or in some other
application or combination of applications, that is where you should make the determination.  Self
test is not a normal operating condition and is not a sufficient tool to interpret 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, it should be clear to the customer that cosmetic
variations on the replacement display may also exist, and may require the customer to use a work-
around to obscure the cosmetic imperfection.
 4. Customers with cosmetic-based complaints only, that do not conform to the above conditions and
tests will not normally be considered for display replacement.  It will be left to the judgment of the
HP-responsible person working with the customer, to identify work-arounds that are reasonable
and appropriate for the individual customer.  Customers who must have a more perfect display
solution should consider switching to an OmniBook with a DSTN display.
We expect over time that the industry will continue to improve in its ability to produce displays with
fewer inherent cosmetic imperfections, and we will adjust our HP guidelines as the improvements are
implemented.
