    My new powermac g4 1Ghz sometimes auto shuts down, but not in the correct way, it just hard shuts itself down. I have no idea what this could be.. any help would be great, thanks.

    Hm :)
    is the power supply correctly put?
    If so, open the case and check if there are no loose electric cables around...

    I had the exact same problem for the first month or so with a dual 867MDD. I would be in the middle of an email or opening a web page then nothing, the computer would instantly power off. But for the last 4-5 months it hasn't happened once.

    It is a complete mystery to me !!!!

    er

    Actually, sometimes it sleeps, other times it shuts down. From reading the system log i think its a buggy OHCI. I was getting constant shutdowns, then i rearranged by usb devices and it isnt shuting down now.. at least yet.

    why is my OHCI driver putting the system to sleep, why? grrr.

    What usb devices do you have connected to the system?? Have you checked to make sure you have the very latest drivers installed?? Is your OS fully up to date? Have you tried running a fsch -y?? How about resetting the open firmware??

    Its a brand new machine. The only usb devices connected are the apple keyboard and apple pro mouse. I'm running MacOSX 10.2.4.

    Have you run the software update to make sure everything is 100% current?? How about try a different keyboard and mouse?? It's possible you have a defective keyboard and/or mouse there (it happens).

    How about the fsck -y and resetting the open firmware?? Have you done either/both yet??

    hmm

    i dont have another usb keyboard to test with. regarding the fsck -y or openfirmware reset, i havent done either, as the box is brand new, there should be no problems with that, i think.

    Re: hmm

    Should and should not and reality are often three different things. DO the fsck -y as well as reset the open firmware.

    Have you tried calling Apple about the issue?? Since the system is "brand new" you are covered under warranty. What software have you installed onto the computer?? Is all of it OS X native (10.2, not older versions) or compatible?

    What other hardware do you have either inside or outside the computer? Remove all third party hardware from the system (inside and out) and see if the problem remains.

    hm

    Since im getting system events for sleep i dont see how fsck -y could fix anything. All my software is 10.2 compatible, its pretty much the standard stuff. And i have no 3rd party hardware in this system.
