MacBook (13-inch) Troubleshooting — Symptom Charts 

Symptom Charts

Before turning to the symptom charts, you should have completed the following steps on the 
Apple General Troubleshooting Flowchart:

Gather information

Verify the problem

Try quick fixes

You consult the symptom charts as part of the Research troubleshooting step (and sometimes as 
part of the Try Quick Fixes step).

The Symptom Charts included in this chapter will help you diagnose specific symptoms related 
to the product. Cures are listed on the charts in the order of most likely solution: try the cures in 
the order presented. Verify whether or not the product continues to exhibit the symptom. If the 
symptom persists, try the next cure. 

Note: If a step instructs you to replace a module, reinstall the original module before you 
proceed to the next step.

Use Software Update in Mac OS X system preferences or see the Apple Software Updates

Reseat AirPort Extreme Card and make sure AirPort antenna cables are fully connected. 

Remove and reinstall the AirPort software.

Replace with known-good AirPort Extreme Card.
