My 2,88GHz early 2008 G5 failed to pass post, the diag leds showed 'errb' lit indicating a failed cpu-B. I replaced Both cpus (quad-cores Xeons) and the 'errb' is still lit !?! So I replaced the Logic Board and the 'errb' led is STILL on !?! I pulled the battery and put it back, hit every possible reset this model has.
It doesn't seem to be HW.. what else can cause this? I plan to replace the battery next. It never gets to chime. Memory leds are good. Please email me directly with suggestions to fix this: urhere@mac.com
