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 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. It might 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 sh\
owing 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 might 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 might 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 notebook display.

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: 
View the notebook under the customer’s normal operating conditions. 
 This means that if the customer uses the unit 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. 
Use the table below to determine whether the display should be considered for replacement. 
These are the only conditions in this guideline that might call for a replacement due to a defect in 
material or workmanship based on the HP Limited Warranty Statement. 
If a display is considered for replacement, make sure the customer understands that cosmetic 
variations might also exist on the replacement display, and might require the customer to use a 
work-around to obscure the cosmetic imperfection. 
Customers with cosmetic-based complaints 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 the 
individual customer. Customers who must have 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.
