fully shut down (not a restart). This section describes what to do if beeps are heard during 
the startup.  
Note:  
 The computer has a memory expansion slot that accepts a 1.25-inch (or shorter) 
PC-2700S or better, SO-DIMM memory card. Refer to the Memory Replacement 
instructions for removal and installation. 
Computer beeps once at startup
 
1. One beep means that no RAM is detected.
2. If a RAM card is installed in the expansion slot, remove it and put in known-good and  compatible RAM and restart. 
• If symptom does NOT repeat, replace RAM card. 
• If symptom repeats, replace logic board.
3. If no RAM card is installed, replace logic board. 
Computer beeps twice at startup
 
1. Two beeps means that EDO memory is installed in the expansion slot. The iBook does  not accept EDO memory.
2. Replace RAM card with known-good and compatible RAM and restart.  • If symptom repeats, replace logic board. 
Computer beeps three times at startup
 
1. Three beeps means that no RAM banks passed memory testing.

• If symptom does NOT repeat, replace RAM card. 
• If symptom repeats, replace logic board.
3. If no RAM card is installed, replace logic board. 
Computer beeps four times at startup
