Seems, as if I am having the same problem as a few people on the news group. My computer doesn't like to take its nap like a good 1500$ computer! Put the computer to sleep via menus .... can't power up from NON-Apple USB mouse and/or keyboard. Requires powering up from button. On occasion ... the fans rev-up to full RPMs while asleep AND can't revive the beast except via full reboot. ... Now, I've heard THESE stories a couple of times: http://daringfireball.net/2004/05/energy_saver http://email@example.comOdaDYvp0u.4@.689543f9 http://forums.whirlpool.net.au/forum-replies.cfm?t=197675 I've reset the machine WHILE on the phone with Apple via the discussion group. I've made sure my firmware is up to date, ran the Hardware utils w/ nothing coming back as "broken" such as the OTHER posting says ... and I'm running 10.3.4. System : PowerMac 1.6 80 + 160 SATA drives 768mbs of RAM (2x128,2x256) 2-USB Cards - PCI, CompUSA generica (10 total extra ports - all stuff off loaded to these cards w/ 1 bluetooth internally put at the end of one card - D-LINK) That's about it. The machine is under a week old and I simply can't seem to fix the problem based on any solutions I have seen. Suggestions, beyond the answers given in the above websites? Or should this simply be a "lug it back to Apple Store" thing? I want constructive feedback ... cuz I've tried everything that a responsable techie would do.
