Testing Hardware Operation
The e-Diagtools program included with your computer provides two levels of testing:
• Automated testing using the basic hardware test.
• Advanced testing using individual hardware tests.
The tests are designed to run after the system reboots. This ensures that the computer will
be in a predictable state, so the diagnostic program can properly test the hardware
components. The tests are nondestructive and are intended to preserve the state of the
computer. The computer reboots when you exit the program, so drivers can be loaded.
To run the diagnostic test
1. Restart the computer: click Start, Turn Off Computer, Restart.
2. Press F10 when you see the HP logo.
3. When the menu appears, press Enter to run e-Diagtools.
The first time you run the program, you will be prompted to select the language for
the program.
4. Follow the prompts to run e-Diagtools.
5. When the Configuration Description appears, check the list of detected hardware.
If a device is not detected, it may be configured incorrectly in the BIOS. You can
confirm the problem by running BIOS Setup utility and checking the settings.
6. Run the basic test. Press F2 to start the basic hardware test. The results appear when
the test is complete.
7. If you intend to exit without running the advanced tests, press F4 to view the Support
Ticket. Press F3 to exit e-Diagtools.
8. Optional: run the advanced tests. Press F2 to open the advanced test screen.
