Q: Quicksilver 2002 in constant sleeep?
Greetings!.
I bought a used Quicksilver 2002 about a year ago. It didn´t power up, and so we thought it was a dead PSU. Trying to check it, it was indeed bad, so we found a used PSU pull from another QS. Once we installed it, the failure remains, so we were told to replace the Logic Board. And so we did. Found a working pull at eBay and installed it.
Then the story comes: We were lacking two of the screw bases that tighten the CPU to the board and chassis. Still we managed to install the CPU on the new logic board. The failure now was: Once I press the power button, it lights itself and the fans spin up, but as soon as I lift my finger from it, the button light goes off, and the red LED on the logic board remains on until I keep the power button pressed and it shuts off.
At first we replaced the PRAM battery, and then it went alive. It was working sweetly for two weeks, handled very carefully since the CPU was not fully tightened because of the lack of these two screws.
Then we found the two remaining screw posts, and decided to shut the machine off and secure the CPU by putting the two posts. After we did this, the Quicksilver never got on again. Same failure. Press the button, it lights up, fans spin up, red Led goes on. Release the button, light goes off, red Led remains on until button is pressed on for a while and machine shuts off completely.
We thought it could be a bad PRAM battery, and so we replaced it by a new one. No changes. Pressed the PMU reset button, followed the procedure " with everything unplugged press the pmu on slow count to 5, then press the power button on slow count to 5, let sit overnight, reconnect and start", without any success.
I am very worried about this: "Do not press the PMU reset switch a second time because it could stop the PMU chip from responding.". What If I might have pressed the PMU reset button a second time, inadvertently? Is this leading to a permanent damage of the logic board? Can this be solved in any way? I have no way to perform any other kind of reset, I think, since I am not getting startup chime, nor USB keyboard/mouse sign of life.
I also tried swapping CPUs with a perfectly working GigaDesigns G4 1.66 upgrade I have working on another G4 (A Gigabit Ethernet) with the proper bus switch changed (G.E. is 100Mhz bus, qhile QS is 133Mhz bus), with no avail. Swapped RAM sticks for known working ones (pull from a working Flat-PAnel G4 iMac which uses 133Mhz Ram sticks too) and again, no success.
can... anyone... help me... please?
