3-20 Troubleshooting and Diagnostics Service Manual
Diagnostic Tools
This section describes the following diagnostic tools you can use for troubleshooting and repairing the
notebook:
• Notebook e-Diagtools diagnostic program (below)
• Power-on self-test (page 3-20)
• Sycard PCCtest 450 PC card (page 3-26)
• Windows Management Instrumentation (page 3-27)
• BIOS Setup utility (page 3-27)
e-Diagtools Diagnostic Program
The hardware diagnostic programs provide two levels of testing:
• User-level testing using a basic hardware test.
• Advanced testing using individual hardware tests.
The tests are designed to run after the system reboots, 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 reboots when you exit the program so drivers can be loaded.
Updating e-Diagtools
You can download the latest version of e-Diagtools using e-Diagtools for Windows.
