Swapping modules that might be defective with others known to be good is generally an ideal way to find the module responsible for the problem. A failure symptom is rarely caused by more than one module, so you will not usually need to replace more than one to correct a particular failure. After you replace a module, the notebook will normally be in a confused state and lock up when you apply power. If this happens, press the reset button: this turns the notebook off, so that you can restart it in a known state. Verifying the Repair Before returning the repaired notebook to the customer, verify the repair by running the following tests: • e-Diagtools Basic Diagnostic Test. Run the basic test of the e-Diagtools diagnostic program (page 3-18). -and- • Function Tests. Run tests that check the repaired function, such as those in e-Diagtools (page 3-18). -and- • Failed Tests. Run any other tests that failed during troubleshooting. 3-4 Troubleshooting and Diagnostics Service Manual
