How to Use the Symptom Charts
The Symptom Charts included in this chapter will help you diagnose specific symptoms related to the product. The steps to solve a symptom are listed sequentially. You might not need to perform every step before the symptom is solved. Start with the first step, and then test for the symptom. If the symptom persists, replace any modules you removed, go to the next step, and test again. Continue down the list until the symptom is solved.

If no RAM card is installed, replace logic board. Two beeps means that EDO memory is installed in the expansion slot. The iBook does not accept EDO memory.
