The tests are designed to run after the system reboots, so that the computer will be in a predictable
state during the tests. The tests are non-destructive, and are intended to preserve the state of the
computer. The computer reboots 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),
