This Power Mac G4 has Mirrored Drive Doors.

80回答 すべてを表示

Mac g4 mdd 1.25 ghz boots but no on light, no chime and no video.

I've had the PSU rebuilt. Replaced the battery. Changed the hard drive. Replaced the optical drives. Changed the video card. replaced the memory. Tried holding down the PMU and the on button for 15 seconds, no good. Pulled all the cables and held the on button for at least 15 or more seconds, still no good. What's left besides R&Ring the motherboard and or the daughter board?

The button your refering to is called PMU and yes I've pressed it many times. I've learned from past experience with other Mac's by holding the PMU button and the start button for fithteen seconds or more would solve the problem. Not in this case.

The board your refering to is not my board. I have a G4 MDD 1.25 GHZ Single CPU.

Just replaced the motherboard. The original had a broken capacitor. Also The PSU was dead so I R&R'd it. boots but has the original problem. How do I know if the CPU is bad?

@alm1ghty55 The CUDA button is labeled S4 in the image I provided below. Look near the bottom left corner of the image. Hopefully this helps.
