Running OS X 1.5. If I've opened Classic to view a Classic document,\nthen closed all docs and aps and left the computer, it will go to\nperpetual sleep. No key stroke will awaken it. I have to shut down and\nrestart with the button.\n\nAnd . .sometimes on restart I'll get a blank white screen. I believe\nI'm getting the smiley face, but the screen goes blank. Requiring\nanother button shutdown and restart. Then it boots.\n\nOn days when I do not activate Classic, computer sleeps and awakens\nnormally.\n\nI've read somewhere that in OS X running Classic, reawakenings are\nSLOW. If they're talking about 5 to 10 minutes, I haven't waited that\nlong before forcing a restart.\n\nDoes anybody recognize this symptom? Is it normal or potentially\ndangerous>? I've already lost one hard drive on this iMac and the new\none is one month outside of it's 90-day warranty.
