MacPro won't wake up from sleep

Upgraded Monday to SL, no problems except for 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

Jason

Thursday morning....came into office and MP no display, power light off, no response. Had to hold in power button till heard a click, then power up.

Computer Sleep set to never.
Display Sleep set to Never.
Put the hard disk to sleep when possible - turned off.
Start up automatically after a power failure - Checked.

Under Schedule, set it to Start up or wake every day one hour before I get to work.

This is a major pain. Anyone have any thoughts? I put the screen saver to never now.

Yesterday after several reboots I booted backup and didn't turn on Fusion. After running fine for 1-1/2 hours, started up Fusion. Ran fine for several hours. When I left for the day, I turned on screensaver. Came in today (Friday) and screen saver still going.

Had to leave office for a bit, so I went ahead and put monitors to sleep (hot corner). When I came back 30 minutes later, no response. Power light is on, but screens are off. Hit caps lock (only button on keyboard with a light) and light does not come on.

Hard kill to bring it back to life.

Next test will be sleep mode.

Anyone have any thoughts, comments, feedback...sympathy??

My iMac 24-inch for two days in a row now will not wake from sleep by me just pressing on the spacebar. Pressing power button didn't work either. I had to turn the surge suppressor on and off today to get a response. Yesterday I changed socket for the power cord. Doing that allowed me to restart with the power button (yesterday) and today it restarted on its own.

And there was never a power failure; no directory damage as a side effect result of this? And you have begun to rule out devices that interfere with low power sleep mode?

Wake from sleep use to be an issue on Mac Pro and required an EFI firmware update. Also, excessive inrush current and problems with underpowered UPS (anything less than about 1200VA should be suspect and replaced with 1300-1500VA).

Same problem on my 13 in MacBook Pro. Just purchased it one month ago. Upgraded to Snow Leopard last week. Now, when I'm away from it for a while and it goes to sleep it won't resume. Touching the keyboard, track pad, or a "normal" push of the power button doesn't get a response. I hold the power button down for several seconds several times and then it will restart.

When I came home and found it unresponsive like this today, the computer was running hot (very warm to the touch) and the fan was blowing. In my use of it for this first month the fan has never before come on (I didn't even know it had a fan). This doesn't seem like a good thing.

What's the best way to get a response from Apple on a problem like this?

I have had the same problem with a brand new MacPro. The unit was bought about 4 weeks ago. Pretty much from the first day before any extra software was installed it would go to a black screen, no network, no power to mouse and would not respond except by powering it off. The power savings were set for "never" and it would still do it. I made sure that nothing but the Apple supplied keyboard, mouse, and monitor were attached. I ran TechTools and Memtest and found nothing wrong. I called Apple and after some time on the phone with Tech Support and resetting everything they asked they could not figure out the problem and sent me a new unit calling the old on DOA. I got the new unit, set it up, without incident, and now 2 weeks later the user just called telling me that it is having the exact same problem as the first unit. I don't know what to do at this point. My user has spent over $5000 on a computer that we can't get to work for more than a few hours.

I have the same problem after I upgraded to Snow Leopard. I purchased Macbook Pro 15" couple of months back and upgraded to snow leopard last week. It was working fine before the upgrade. Now randomly it does not wake up from sleep after I open the screen. I even reinstalled Snow Leopard, still the problem remained. Anyone has any luck on this problem?
