IMAC snaps off during operation Console says cause - 122

My IMAC G4 (five years old) just snaps off sometimes after 10 minutes operation, sometimes a half hour or hour. If left off for a while you can always start it again but it will shut off again after a while.. The last line of console when it does this is " PMU forced shutdown, cause = - 122
What is that and how can it be fixed?

Sounds like a power supply issue. You will need to take this to an apple dealer and ask them about it. This one is not an easy fix as it is a hardware fault.

Imac g4 won't start but shuts down when apple logo appears on screen


Are you sure the iMac is really shutting down or just turning off the backlight? The tell-tale sing would be to let the unit fully boot-up (wait 3 minutes) and the press the button the apple keyboard that ejects the CD-ROM. If the CD-ROM door opens, you iMac is running with disabled or broken backlight.
The inverter circuit on the iMac G4 is known to be weak.
There could be another problem, though. The iMac G4 is also known to have weak internal power supplies. Here's how you can tell:
Hold down the CMD OPT "O" and "F" keys at the same time while pressing the power button. This will tell the iMac that you want to boot into the Open Firmware shell, bypassing the Mac OS X startup. If this works, your power supply is good, the inverter is good and you have a problem with your Open Firmware boot string. To fix the boot string, Power on the unit while holding down the keys CMD-OPT-P-R to zap the parameter RAM (PRAM) and reset everything to defaults.
If you were not able to boot into the Open Firmware shell, your problem is either a failed power supply or a failed screen backlight. The last possible culprit is your iMac could suffer from "Bulging Capacitor Syndrome", where a batch of iMac G4s, iMac G5s another electronics were fitted with a bad batch of capacitors. Eventually, the caps will rupture and cause irreparable damage to the logic board. Only way to verify this is to pull the unit apart and visually inspect. If you see little green or blue cylinders that seem to be bulging or oozing a thick oily goo, that's your problem. Only recourse is to shop around on eBay and look for a replacement logic board.

Unable to turn on the computer and power supply is OK because other devices are plugged into it. Tried procedure in apple manual which says to hold down power button and at same time hold down 4 buttons on...


The iMac G4 will refuse to turn on if the logic board battery is dead. Since this model Macintosh is now about eight years old, it's quite reasonable to suspect your battery is dead. Battery replacement is a relatively simple task for a certified technician, but unfortunately the battery in this model is not a user-replaceable part.

Can I connect my apollo 2250 to my old imac?


OS X drivers for the Apollo 2250 apparently exist only in 10.5 and 10.6, both of which your iMac G4 is too old to run.
If you have this printer attached to another computer on your home network, you could activate printer sharing and allow your G4 to print to it that way.

DVD player skips audio and/or frames


PowerBook G4 is at least a five-year-old machine at this point. A DVD drive can **** in lots of dust in five years. Try hooking up to an external DVD drive. If it plays the same discs with no problem, you need a cleaning or replacement. Frankly, an external DVD drive is cheaper than replacing your internal drive.
