Diagnostic Tools 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 3-18). • Sycard PCCtest 450 PC Card (page 3-21). • Desktop Management Interface (page 3-22). • BIOS Setup utility (page 3-24). 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 If you need a diagnostic floppy disk, insert a formatted floppy disk in the floppy drive and do one of the following: • Check the \Dmi\Hpdiags directory. If diaginst is in this directory, run it. –or– If TopTools is installed, check whether the DiagTools page can create the disk.
• On any computer with World Wide Web access, download the diagnostic software package from the OmniBook website (see page vi), then follow the instructions. 3-12 Troubleshooting and Diagnostics HP OmniBook 900
