![]() This model included slot 1 with a standard VGA port and a proprietary ADC (Apple Display Connector) port, while slots 2–5 are unused. The ports on the back included stacked headphone and line-out speaker 3.5 mm jacks a modem (telephone) port one ethernet port two FireWire (400) ports and two USB ports. The bottom-center features a prominent chrome-finished speaker (without a protective grille). Below the optical drives was the power button, and two additional smaller buttons-reset and “interrupt” buttons-both used to recover from system-level issues. This example includes a DVD-ROM drive in the top space and no device in the lower space. ![]() The top included spaces for two optical drives. The front of the Power Macintosh G4 “Quicksilver” was opaque silver (replacing translucent plastics of previous designs). A few Quicksilver models were available with different levels of processors, drive capacities, and RAM options. Internally, it included dual 1.0 GHz PowerPC 7450 (or 7455) G4 processors, 512 MB RAM, an 80 GB hard drive, and a wireless connection was available with the addition of an optional AirPort (802.11b) card. No other model will do it, but this one has a power button like the origin Apple ADB keyboards.An Apple tech told me that the keyboard power button would override and start a G4 tower with a dead FPB.The Power Macintosh G4/1.0 GHz was nicknamed “Quicksilver” because of its new silver color and its significant speed upgrades from the previous graphite G4 model. Sometimes the FPB goes belly up and you either replace it or, if you can find one in a thrift shop, connect an Apple USB keyboard model M2352. Sometimes pressing the button in the upper left quadrant will overcome the issue: It's ofter cheaper to get a working G4 MDD and either transfer your drives to it or transfer that power supply to your current G4.Īnother common startup issue with the G4s as a family is the "front panel board" or "FPB," the board behind the front decorative panels that holds the power button. They are not hard to replace but are getting hard to find. They always left Apple with someone else's brand on them so I doubt that is the issue.Īs I told Peter, the 360W power supplies were a weak point in MDDs. I've never seen a "genuine" Apple "PRAM" battery and I owned plenty of Macs that used that same battery. This site, created by one of our valued former contributors, may be very helpful in keeping your old veteran in service: The original 400W PS was quite robust but had cooling fans salvaged from a WW2 bomber! responding to a flood of noise complaints, Apple swapped them out for a quieter 360W model that ultimately proved less reliable as the old and noisy ones with the B-17 cooling fans! ![]() The worst for power issues were the Mirrored Drive Door (MDD) G4s. When he returned, the computer was unresponsive and the case adjacent to the the PS was very hot. The update apparently stalled and the computer was stuck in a loop, creating a lot of heat. My son set up a software update and left the house to run errands. I believe that heat build-up accounted for the loss of the PS in one of our G4s. That would account for the "dried out" comment you saw. I've heard of G4 power supplies (PS) failing due to faulty capacitors or ones that were nicely baked due to being at the top of the heat column in the computer case. If "condenser" is the same as "capacitor" then, yes, there is some credence to that.
