MacPro won't wake up from sleep
Goes to Sleep and won't wake up. I have a MacPro connected to 3 monitors.
Monday, after lunch machine was unresponsive. Monitors where in sleep mode. Power indicator light on Mac was on. Had to hold in power button and power up. Checked power settings. Changed Computer sleep from 2 hours to Never. Changed Display sleep from 30 mins to 3 hours. Screen saver (iPhoto folder) set to 20 mins. No problems rest of Monday.
Came in Tuesday morning, same thing as above. No response to any keyboard or mouse activity. Optical mouse light was on. After boot, changed Computer sleep to Never. No other problems.
Came in today (Wednesday). Same problem. After boot, changed Display sleep from 3 hours to Never. Was away from desk for about an hour. Came back, screen saver was running, logged back in, all good. Turned around to work on another machine. Turned back to Mac, Screen gone, monitors sleeping. Power light not on. No response to any input. Hitting power button did nothing. Had to hold it in and then you could hear machine shut down even tho the light was not on.
This machine is only 3 months old and never had this problem till upgrade. This is a very big problem cause I run two virtuals in Fusion and they don't like being killed this way.
Any thought, ideas, comments, etc?
Thanks
