Computer gets hot
Computer pauses or runs sluggishly
Plug in ac adapter for 24 hours to charge backup battery. It is normal for the computer to get hot. Make sure the air vents are clear. DOS games and other programs that drive CPU usage toward 100% can contribute. May be normal Windows behavior (background processing can affect response time). If the hard disk has spun down to conserve power, it can take several seconds to spin up. You can hear this. You can run BIOS Setup and change the hard disk timeout to match the Suspend time-out. Certain background operations (such as HP COE virus scans) can affect performance while theyre running. Some file browsers may be unresponsive while theyre processing a graphic image or waiting for broken network connections to time out. Run BIOS Setup and try turning off smart CPU mode.

This section describes the following diagnostic tools you can use for troubleshooting and repairing the OmniBook: OmniBook hardware diagnostic program (below). Power-on self-test (page 3-17). Sycard PCCtest 450 PC Card (page 3-20). Desktop Management Interface (page 3-21). BIOS Setup utility (page 3-23).
OmniBook Diagnostic Program
The OmniBook hardware diagnostic program provides two levels of testing: User-level testing using the basic hardware test. Advanced testing using the individual hardware tests.
Figure 3-2. OmniBook Diagnostic Screens Basic and Advanced
The tests are designed to run after the system reboots. This ensures that the computer will be in a predictable state, so the diagnostic program can properly test the hardware components. The tests are non-destructive and are intended to preserve the state of the computer. The OmniBook reboots when you exit the program so drivers can be loaded.
Creating a Diagnostic Floppy Disk
After inserting a formatted floppy disk in the floppy drive, do one of the following to create a diagnostic floppy disk: On an OmniBook with a factory software installation, run diaginst from the \Dmi\Hpdiags directory on the hard disk. or If TopTools is installed, use the DiagTools page to create the disk. On any computer with a CD-ROM drive, run diaginst from the \Omnibook\Dmi\Hpdiags directory on the OmniBook 4100 Recovery CD.
On any computer with World Wide Web access, download the diagnostic software package from the OmniBook website (see page vi), run this file to unpack the files, then run diaginst to create the diagnostic disk.
Running the Diagnostic Test
1. Insert the diagnostic disk in the floppy drive. 2. Reboot the OmniBook. 3. Go through the first several screens. 4. When the hardware detection finishes, check the list of detected hardware. The following information and devices should be listed if applicable: Product name Processor type BIOS version Serial number Cache memory

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 manufacturers 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 customers complaints of cosmetic imperfections in their TFT displays: 1. The unit should be viewed in the customers 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 workaround 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.
