Mac Pro will not wake up from sleep, must hard reset

[ColdCase]

Yes mine now sleeps promptly, used to take near 60 seconds.

[kenucklehead]

Yup... seems the most recent update has fixed the issue. Not a single problem since!

I am still having the same issue, despite upgrading to 10.8.1

[jradsta6]

has anyone found a fix for this yet?

[tamvly]

The "awake from sleep" problem has occurred twice on my 3,1 MP since the 10.8.1 upgrade - it seems to happen when I try to awaken it shortly after it is put to sleep. Longer time frames have never been an issue. Strange.

It just started happening with mine. 2008 Mac pro and I haven't changed anything. the other day my 2nd internal HD disappeared from my desktop but it was showing up in Disk Utility. It didn't show up as bootable, either. Had to run tech tool pro to have it show up. My preference panel wouldn't work either.

I haven't updated anything major. I'm thinking flash was the latest update. I wonder.....

I've found same problem, after my mac pro sleep it can't wake up a display.
(system woking nice but display remains blanks) when using DP.
I've found found problem when used DVI.

My configuration.

Mac Pro 6-core 3.2 -5870 's DP ----------> DP Dell U2711

I have Snow Leopard 10.6.8. on a MacBook Pro. It will randomly refuse to wake up from sleep. It can happen either from putting it to sleep from the drop down menu or from closing the case. The fan does not run, the light pulses, but only way to get back in operation is a hard reset. The problem is getting really annoying.

Might want to chime in on the MacBook Pro forum, as they would likely have a better idea of what's going on instead of here in the Mac Pro forum. As default go-to solutions, have you tried resetting the PRAM or resetting the SMC?

same issue as other posters. early 09 MacPro 10.8.2

I'm trying out the schedule settings in energy saver. Will re-post if this fixes it

Hi all,

I was having similar sleep/wake up issues and spent days trying to find a solution - tried various suggestions from forums but none worked. Finally stumbled upon this thread over at Apple Support Communities:

https://discussions.apple.com/thread...rt=90&tstart=0

And this did the trick. Driver updates from Nvidia suggested by "bonfire" in this thread above solved it for me. And finally last night, I was able to put the MP to sleep and woke up this morning and it was still in sleep mode and it woke up promptly as it normally should.

Thanks,

SK

Do you have "wake for network access" enabled in the Energy Saver settings? My system started doing this after I turned that on, I believe it has something to do with the wake-on-LAN functionality and not power nap.

Edit: never mind, just read the link above which confirms that it is indeed related to wake-on-LAN.

Hi,

I have noticed this same wake up issue on my early 2011 MacBook Pro running 10.7.5. This has only just started happening in the past week.

I noticed this same kind of thing on Apple's site here: https://discussions.apple.com/thread...rt=90&tstart=0 but they mainly talk about issues since the 10.8.2 upgrade and with NVidea graphics cards. There seems to be a couple of solutions there, but has anyone had this issue with the AMD Radeon HD 6490M 256 MB graphics card (assuming it's the graphics card making the system not wake up), which is what mine's running?

Cheers, Will

I too am experiencing this problem but I am running on leopard on a 2009 macbook pro. Since all of this happened around the time that MT came out for several people simultaneously maybe it was a bad update effecting multiple systems?

So right now, my computer will sleep and wake when I sleep it manually, and also automatically under settings in Energy Saver.

I have a Mac Pro 5,1 (mid 2010), running similar configuration to yours.

ML 10.8.2
6-Core 3.46Ghz
24GB RAM (Crucial)
NVIDIA 670GTX 4GB

and have the sleep problem.

I tried SMC reset several times, but problem persists. As soon I put the Mac Pro to sleep, it won't wake up.

Any ideas what I can do to get it working again?

No Sleep / Wake problem on 2008 MP - 10.6.8 - 2-2.8 Xeon - 8GB Ram.

Maybe once last week it happened - but no proof what mode it was in or mode intended.
Hard reset was done.

I'm more than reluctant to go ML.

With 4 - 1TB drives, I'm considering flipping #1 with #3 that rarely gets used,
clean strip #3, load OS on him to see if by chance hidden HD issue/s
just go away.

Then go with SSD in the end on drive 1.

Just browsed into manual - statement concerning internal battery could make start up difficult caught my eye.
May not be related - but would like to know if it's condition can be found
