Hello, seems like a RAM problem, or logic board...


The following table lists the new tones and their meaning:


Tone(s) Description

1 tone, a 5-second pause, repeat No RAM installed

3 successive tones, a 5-second pause, 3 successive tones RAM does not pass data integrity check

1 long tone when holding down the power button Firmware upgrade in process. See About firmware updates for Intel-based Macs for more details.

3 long tones, 3 short tones, 3 long tones Firmware restoration from CD in process. See About the Firmware Restoration CD (Intel-based Macs) for more details.

Can you count the beeps or flashes?


1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable


In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.


Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
