    Is my iMac G4 running out of battery?

    I've never had the battery run out of any computer so I don't exactly know how to diagnose it; I just know that the computer might not remember its time/date while starting up offline, but I haven't noticed any clock weirdness so far. The iMac has been starting up without the startup chime for...

    iMac G4: How did people optimize it for making music? (MIDI rec latency issue)

    I'd like to occasionally use my G4 for musical drafting. I put an SSD into the iMac recently, but haven't updated the RAM from the 1GB it has now. I probably will eventually, but somehow it feels like it's not the culprit, or that it's not the only culprit to the issue. The issue is that even...

    I'm in the process of opening up a G4 for an SSD replacement. Never done this before. I started with the obvious iFixit article, and where it fell short, headed to Youtube.

    Recently became an owner of iMac G4, 1.25 GHz (M6498). It has 2GB of RAM, 128GB SSD and is running fresh install of 10.5.8. Unfortunately overall performance is quite disappointing and is lower that I expected. Comparing to my PowerBook G4 12'' 1.5 GHz it's significantly slower. Benchmarks...

    iMac G4 won't boot, fan twitches

    Alright guys, so I'm having some troubles with an old flowerpot iMac. About a month ago I knocked a glass of water on the desk where the computer is sitting.

    iMac G4 - 160 or 180 Watt PSU?

    I just picked up a 17 inch iMac G4 cheap on Craigslist, model number M6498. It doesn't work, and from what I've been seeing, the problem is most likely to be the Power Supply. When the power button is pushed, nothing happens at all, not even the fan spins up. Is this the power supply or could it...
