Diagnostic Tools
This section describes the following diagnostic tools you can use for troubleshooting and repairing the
notebook:
• e-Diagtools diagnostic program (below).

• Sycard PCCtest 450 PC Card (page 3-26).

e-Diagtools Diagnostic Program
The e-Diagtools hardware diagnostic program provides two levels of testing:
• Basic user-level hardware test.
• Advanced individual hardware tests.
Figure 3-2. e-Diagtools Screens — Basic and Advanced
The tests are designed to run after the system restarts, so that the notebook will be in a predictable
state during the tests. The tests are non-destructive, and are intended to preserve the state of the
notebook. The notebook restarts when you exit the program so drivers can be loaded.
Updating e-Diagtools
You can download the latest version of e-Diagtools from the HP Notebook web site (see page vi).
Follow the instructions included with the new version.
