Mac G4 Tower Won't Shut Down...

benv
I have a Mac G4 Tower, with OS Tiger installed and it never shuts down, it always restarts. Does anyone have an idea of what it is?

Have you tried unplugging it? wink.gif

How do you shut it down? Via the apple menu? the terminal? button on the front of the machine? keyboard?

try init 0 in the terminal. It's universal amongst all UNIX systems. Else, contact Apple Forums.

try int0 from the terminal as Xboxrules suggested. I would also try a repair install of OS 10.4 as some setting somewhere may have been corrupted. Lastly, have you tried holding the power button for 10 seconds and shut it down that way? Not the best idea as it is hard on the system, but it will tell you if it's a software or hardware problem.

Of course, before using any of the above methods (the init 0, or the holding the button down, or any other methods that don't really give the OS time to close programs and prompt for document saves) close all applications manually and save your data.

open disk utility and verify the permissions and then verify the disk.


have you used any 3rd party programs to alter any system settings?

    I will be working on a G4 (I think) tower and the user is saying that the white power light is one
    when he pushes it but no other power seems to go through to the computer or monitor (no chime
    sound). He already replaced the 3.6 Volt battery on the logic board and also hit the reset button
    (CUDA). I haven't worked on these for a long time and have some questions: 1. Can I test the
    power supply using a 20 pin power supply tester? I did some reading up on this tower and it seems
    that it will have 24 pins on the main power connector to the board (so 4 extra pins). 2....
