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.

b. On OmniBook 4000CT models, if more than 30 total pixels anywhere on the display are bad, then the display should be considered for replacement. On OmniBook 600CT and OmniBook 5000CT models, if more than 15 total pixels anywhere on the display are bad, then 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 who, in 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 their ability to produce displays with fewer inherent cosmetic imperfections and will adjust our HP guidelines as the improvements are implemented.

User interface

Power

Keyboard: 85-key, touch-type keyboard; industry standard, full sized key spacing with embedded numeric keypad. Includes 12 function [Fn] keys located on the top key row above the numeric keys.

Microsoft mouse compatible, 2 button pop out mouse emulates desktop mouse operation. Located in the upper right corner of the unit, accessible by a clearly marked push button.

Optional pointing device: Serial mouse or with the enhanced port replicator a PS/2 mouse port.

Battery type: 9.6 Vdc rechargeable NiMH. NiMH battery does not require complete discharge before recharging. There is no "memory" effect that reduces battery life. Lithium Ion battery, 9.6 Vdc rechargeable, standard for the OmniBook 600CT and can be used in the OmniBook 600C with optional battery pack, p/n F1121A

Recharge time: NiMH quick charges in approx. 90 minutes when the unit is off or in use. Lithium Ion quick charges in approx 2 hours with unit off or in use.

Battery life: 3.0 to 3.5 hours depending on screen brightness and I/O usage.

Power

Battery signals: 2-minute low battery warning followed by controlled shutdown to preserve data for several days prior to recharge.
