Apple Hardware Test 2.0.1 (AHT)
Starting with the PowerBook G4 (17-inch), the Apple Hardware Test software will be
incorporated into the Software Install and Restore DVD. There is no separate CD for this
diagnostic.
Previously, the C key was held down to boot into the diagnostics. With the combined DVD,
this action will boot into the software restore section of the disk. In order to access the
AHT on the DVD follow these steps:
1. Insert the DVD named "PowerBook G4 17 inch Software Install and Restore" that
came with your computer.
2. Hold down the Option key and restart the computer.
3. Click Apple Hardware Test volume in the startup manager.
4. Click the arrow that points to the right.
5. Follow the on-screen instructions.
Note: Apple Hardware Test 2.0.1 is not backwards compatible with PowerBook computers
prior to the PowerBook G4 (1Ghz/867Mhz).
Apple Service Diagnostic (ASD)
MacTest Pro software does not work on this computer since the PowerBook G4 (17-inch)
is a Mac OS X only system. Apple System Diagnostic (ASD) is the replacement and can
be downloaded from Knowledge Base article 112125: Service Diagnostics Matrix.
Important: ASD is not compatible with PowerBook computers prior to the PowerBook G4
(1GHz/867MHz).
