MP 1,1-5,1 5,1 - Sleep Mode

[JoeOIVOV]

I just want to confirm with someone else that my sleep mode is actually broken on 5,1 Mac Pro.

When I go to set it to go to sleep whether manually or let it sit 10 minutes the only thing that happens is the monitor goes off. From reading it looks like the power light is suppose to flash slowly but it doesn't do this. The iMac has sleep mode that looks like its turning it off and it consumes only like 3% of the power it does in normal mode.

I have it plugged into a power meter and on the 2011 iMac when I put it to sleep it consumes like 6watts, but when I put the 2010 5,1 to sleep it stays consuming the same amount of electricity it does in regular mode, power light stays solid, but the monitor turns off.

Does this sound like a bad power supply? Or is this just normal behavior for 5,1 Mac Pro? Just the monitor turns off in sleep mode?

the sleep mode depends on the configuration
btw which PCIe cards are installed.
under catalina the sleep mode on the cMP does not work 99% of the time

 

[JoeOIVOV]

So strange. It's the default configuration.

Single processor 2.8 4 core. 2010 raid card, new battery, AMD 5770.

I shut this beast down 2-5 times a day it would be awesome to get sleep mode working.

Anything specific about the default setup that causes it to be sleepless?

BTW I'm running High Sierra. Don't have a metal compatible GPU yet. I'm thinking if I remove the apple raid card and put in a PCIE NVME drive it might work better? It seems the raid card could be the problem.

 

[tommy chen]

could be
what is the battery status of the raid card?

have you ever done a triple NVRAM reset and SMC reset?

 

[crjackson2134]

Has it always done this?

I suspect your RAID card to be the cause, or something in macOS itself. I had a RAID card that won’t let the system go into sleep mode. I had to remove it.

* Do an SMC/NVRAM reset
* Check all your settings.
* Next try without the RAID card
* Lastly, try a clean install on a spare disk

I’ve had sleep issues in the past that I couldn’t run down before. A clean install on a test drive has proved helpful and curative usually. This of course won’t help if the cause is the RAID card.

Catalina (every version) has no sleep issues on my MP51.

 

[JoeOIVOV]

Yeah I will try the resets right now.

 

[JoeOIVOV]

OK. Thank you for your the help! I got it to go into sleep mode for the very first time on a USB install without the raid card.
Disappointing because I just replaced the battery thinking is what could be causing the issue what a waste of 15$.
It uses 15 watts less in idle an starts up 5-10 seconds quicker.
Is there really no use for this card is what I'm seeing?

I didn't even have to reinstall the OS, just removing the raid card, unplugging the usb drive and my original OS boots up and sleep works.

Thank you for your help. I assumed it required the raid card to use the drive bays or else I would had tried that a while ago, I didn't want accidentally lose any data messing around with the raid.

Yeah, I figured that was the problem. When the Mac goes into full sleep mode, it try’s to cut power to the PCIe cards that are installed. Some PCIe cards stop this from happening, et voilà !

Not sure why you thought it was needed for the drive bays to work.

 

[JoeOIVOV]

Its a strange design coming from a windows background. All the raid cards I've ever seen have the SATA cables directly connected one way or another.
This Apple card I didn't see any cables coming from it, also the pci lane says RAID. Seems like it was tied to the SATA bays in some way.

Thanks for clearing it up for me.
