My Power Mac G5 (pretty old) starts up but then it keeps giving the message "computer needs to be restarted". I tried several times, also disconnected all drives. Two bright red lights come on inside the G5, on the front, and fans are spinning as loud as jet engines. I also tried to restart by keeping pushed the Command key, but it didn't help.
Depends which G5, but...
LED 1—CPU A: red—contact Apple or an Apple Authorized Service Provider
LED 2—Overtemp: red—contact Apple or an Apple Authorized Service Provider
LED 3—Power On: red—the main power is on
LED 4—Trickle: yellow—Power Mac G5 is plugged into the wall correctly
LED 5—Open Firmware good: green—no problem
LED 6—CPU B: red—contact Apple or an Apple Authorized Service Provider
LED 7—Checkstop: red—contact Apple or an Apple Authorized Service Provider
Likely the Thermal Paster needs replacing for one thing, is this a Liquid cooled model?
OK, let us know if we can be of further help. 🙂
Might even join my site & see if there are any other old-timers with G5s still kicking besides me...
