MAC 7600 Won't Shut Down Like it Used to

Am not sure how these Forums work, but for give me if I included too much here, or did not properly follow protocol.
I have a long suffering mystery. It used to be, when I shut down, the subject mac (Power Mac 7600, OS 9.2) stayed shut down till I hit the start button (the triangle marked button on the extreme upper right) again. (Power strip switch stayed on). I relocted the machine from one floor to another in my home, and now it sometimes stays off, but more often than not, it starts right back on as if I hit the start button again, or like I hit the restart box on the shutdown menu. What changed? Is there a box or something somewhere in the sytem folder or somewhere else where I can tweek to stabilize the shut down. Right now I am having to hit the off switch on the power strip, just as the machine starts to try to restart, to keep the machine turned off after the machine shuts down. Not a fatal problem as such, just a nuisance and a mystery. Thanks.

I haven't used that model in years. Hardly would have thought anyone would still be using one. This is not the best forum for such a question. There is an Apple forum (discussions.apple.com) for older hardware and software where you may find more help than here. But then you never know.

I would suggest checking in the Shutdown Items folder in your System Folder to see if there may be an item in there that's forcing a restart. You might also check the Energy Saver control panel to see if you have a setting that is causing the computer to restart.

Other than that I would try posting your problem at the Apple discussions in the appropriate forum. You may find help there. I will also return this to the open pool in case another user has a solution.

There is a button/switch on the back of the 7600 (I had one, but it's been a while) which if put in the wrong position, will do an auto restart for any power failure (and a shut down is considered a power failure for these purposes). I suspect you accidentally moved it from its default position when you moved it and that's why it will not allow shutdown. From what I recall, it is on the right side of the back of computer if you are facing the computer.

HTH.

Dear Steve K.

Thank you for taking the time to write. I took your info to heart and check the System Folder in the areas you suggested. However, everything there seem to be in order. Shall next try your other recommendation, and submit my query to the Apple forum. Thanks again for the suggestions.


Dear Ishan B,

Thank you too, for taking time to write. Soon as I learned of the button/switch I checked. I believe I looked very closely in all areas, after not finding it on the "right side" facing the back of the computer, but I could not find anything that might represent the description. So, shall have to continue to live with the problem. If I have a chance, I will stop and ask at a MAC repair store if I see one whether in fact my Model MAC had such a switch and have him/her point it out to me. Thanks again for telling me of the possibliblity that such might have existed.
 
OK, if you look at your post, the answer is there. The first response below yours (from Jan 21, 7:37am) has the possible solution. There might be a button on the back that can shut off the computer manually. It should also have a small slot going across it that would be for a flathead scredriver. If you use a screwdriver or anything else to turn that button to a certain position when pressed, it will place the Mac in a mode where it will automatically turn on if the power was restored after a power loss. The reason for this would be if you were using the Mac as a server, where you didn't want to have the Mac stay off after the power on your UPS had drained from an extended period of power loss. Once the power would be restored, everything would kick in and the Mac would immediately boot up. My Quadra 650 has this feature as well, and that is how I have it set up since it's acting as an HTTP/FTP server.

Check that and see if it's the problem. You might have to test it out by turning the button (while it's off of course), then booting the Mac, and then shutting it down to see if it stays off.
 
Hmmm... I've got a 7600 here, and I see no such switch on the back of mine... maybe I'm just looking in the wrong place?

One thing I do notice is that under OS X, in the "Energy Saver" preferences, I do have a checkbox-option for "Automatically restart when there's a power failure" -- but I see no hardware-based switch for controlling this.
 
While that is true about Energy Saver, that is under OS X. I don't know if it's in Energy Saver under OS 9.x, which is what this person is running.
 
yes, os 9's energy saver has that option too. and as far as i know, there is no button on the back of that mac to keep it on. i have 2 7500s and a 8600 (and a 9600 mobo) all of which are the same basic mobo as the 7600, and they don't have said switch. but i do know that the power button on the 7600 is on the front, and if you slide the keyboard up against the mac, it could turn it on. it could also be stuck on, as well as the button the keyboard be a little stuck. those would be the first things that i check. the power button on those are know to have some issues, mostly breaking off, but have been knowen to do other things.
 
Man, all this talk of vintage Macs makes me want to replace all of my PCs at home (but my wife would KILL me for taking away her Windows machine :P).
 
i almost pulled my ppc7100 out and put all the nubus vid cards i have in it. i had it maxed out at 5 monitors once apon a time! all 14". lol
 
Nixgeek & El Diablo Con Caca,

Thanks for the feed back. Amen on that switch thing, I was beginning to wonder whether I might be looking in the wrong places. Re- the energy saver thought, I checked again, and the OS 9 indeed had a box to check for "Restart upon power failure." It was unchecked, but the problem is still with me, tho' lately it hasn't come back on immediately. But rather than taking a chance, I've been shutting off the power strip, just as the machine shuts down. Shall have to experiment during the day time when I can still hang around, and see whether it will restart mysteriously in a few minutes. Thanks again to the both of you. VATak
