Hi! This happened to me for a while. Now it does not. I reset PRAM and NVRAM on my G4 17' 10.4.11 for another reason, and the sleep issue went away.....

I am having a slightly different problem on 10.4.11. My energy settings are at sleep never and display sleep is 15 minutes. I will be typing and the system goes to sleep (display and drives). Sometimes it comes back but most times I have to reboot. This seemed to just start happening out of the blue. The only software I have installed is Tech Tool Pro (4.6). I do not think this is it at all but it is the only new software I have installed in several months. Ed ps: I did install some sort of screen saver but did not like it and deleted it._______________________________________________ X4U mailing list X4U at listserver.themacintoshguy.com http://listserver.themacintoshguy.com/mailman/listinfo/x4u Seven Cent Deals - Great legacy stuff Great Legacy Pricehttp:// www.drbott.com/prod/db.lasso?cat=Seven+Cent+Deal -------------- next part -------------- A non-text attachment was scrubbed...
