PCMCIA Hard Drive Advantage:

Flexible disk drive

Built-in I/O

PCMCIA disk drive sustains 1000 g's non-operating shock (vs. 100 g's for typical notebook competitors). The OmniBook 600 design requires additional durability because its light weight and size makes it easy to take wherever users go. Hard drives typically have a higher failure rate then other components due to shock. PCMCIA hard drives stand shock and vibration better then any other hard drive.

TFT Display Quality

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.

The 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 manufacturers cosmetic quality specifications.

Here are some guidelines to use in determining what action to take on a customer complaint of cosmetic imperfection in their TFT display:

1. The unit should be viewed in the customer's normal operating condition. This means if the customer uses the unit predominately in DOS, or Windows, or in

some other application or combination of applications, that is where the determination shall be made. Self test is not a normal operating condition and is not a sufficient tool to interpret display quality.

2. In the customer's normal operating mode:

TFT Display Quality a. If 4 or more variant pixels appear clustered in the area approximated by a

thumbprint on the display surface, then the display should be considered for replacement.
