Macpro turns off when put to sleep?

I have a Early 2008 (Macpro 3,1) Mac pro single quad core machine. It runs great ... But whenever it goes to sleep, it turns off.... The sleep led flashes around 6 times and then ... it turns off..

Any ideas?

I've unplugged everything and it sleep does it...

Help ... these damned power supplies are 400+ dollars.

When you turn the computer back on, does it resume from where it left off? In other words, is the computer hibernating instead of sleeping?

Try resetting the SMC, which is the system management controller which control power management functions.

Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve

Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

When did this start? Is it recent?

It's not a software problem .. happens even with a clean OS installed.

Nope, no resuming where it left off...

Yup, recent...

ASD says everything is ok

What's the OS version and build number?

Go through your Installations Log in System Report and see if any updates were applied last month. I had one come in for my MacBook that changed that build number and then was causing me issues with sleep behavior. I ended up having to reload the OS to clear it up since Apple pulled that update off their site after 48 hours due to issues with it. This may not be your problem, because that update was specific to laptops from them, but it's possible that they released another update similar to it that was built for your type of system. Checking certainly wouldn't hurt.

BTW, the other thread is in this forum if you want to find it and read the full details of it. »MacBook Pro 13 (Latest 2012 Version) Sleep Issues
