MacNN reader Michael De Luca writes "after installing the new power supply and fan offered by Apple to reduce the noise level in the G4 MDD computers, all worked fine for a week and the noise level is markedly reduced." However, De Luca today experienced a problem related to the upgrade: "upon pressing the power button, the power button light glowed as normal, but no startup sequence was initiated. The computer appeared dead." He contacted Apple's support center, and was told what he had experienced was a "known issue," but the representative would not elaborate on the possible cause. But "they did tell me how to fix it," he says.
"The procedure is to disconnect all peripherals except the display, keyboard and mouse, disconnect the power cord, open the computer and ground yourself on something metal. There is a button on the motherboard labeled, "prm reset" which is the power reset for the mother board. Press the button for about 2 seconds then close the computer, hook up the power cable and press the power button again."
"The repair took about one minute to perform and all is back normal. I did note that the clock was set to 1969 and auto time syncronization was reset to off."
