The e-Diagtools hardware diagnostic program provides two levels of testing:

•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.
