powermac g5 blinks

My powermac g5 has started blinking recently. When i say blinking i mean the power led on the front of the tower right above the poweer button. It blinks five time pauses and does it again. Now i know that there is a support page for this problem. However obviously my warranty has expired. So i guess my question is: what does this mean and does

Powermac g5-OTHER, Mac OS X (10.5.8), Dual 2ghz cpu, 8gb ram, 500 gb HDD

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.

I've never completly understood the plus one thing!? So is 5 flashes equal to 4 beeps?


Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...


See which one your G5 has...

Do you have AHT ot ASD for that G5?


If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...
