Computer Cannot Sleep — Even When I Pause Folding

[AirbusFan4444]

Hello,

I am folding on my CPU. I am trying to put my computer to standby/sleep mode, however, even after I press the "Stop Folding" button and the status is "Paused", my computer cannot go to standby, all it does is make the screen blank. How can I resolve this issue? Thanks for all your help.

I assume you're folding with Windows? Which type of installation did you choose? To support Windows GPU permissions, the normal way to install on Windows will start Folding@Home as a program that starts when you log in and I think that blocks hibernation/sleep from occuring. The reason for that is that a GPU work unit can't resume from sleep/hibernation.

As you're only CPU folding, you might try to wipe and re-install Folding@Home as a system service instead. That will not allow GPU folding, but it might perhaps allow hibernation?

PS: Note that Folding@Home folding is time sensitive. Unlike some projects which divide a big problem up into a large number of chunks that can be solved individually, Folding@Home is a relay race where the next folder is waiting for work based on the previous folder's efforts. So if you're going to leave the computer off for days at a time, you should find some other distributed computing project to work on. If you're just shutting off over night, but use your computer every day, your machine can still be useful for Folding@Home. Check if you return your work units before "Timeout" and "Expiry". Ideally you should return most of your work units before "Timeout" because that means less wasted computing power.

This is a useful option to investigate. I have successfully installed FAHClient as a Windows service (on a machine that didn't have a supported GPU) and was able to resume from sleep/hibernation ... though it was a much older version of FAHClient. The do-not-allow-sleep option was added specifically to avoid crashing a WU that folds on the GPU and there is a way to disable that choice, though I don't remember how to do it. (Yes, that's grammatically a double negative.)

It looks like the FAH client is turning off the power standby feature.
C:\Windows\system32>powercfg -lastwake

wait one minute, then take a look at the journal: C:\Windows\system32\energy-report.html

It looks like the developers have incorrectly set the flags for the SetThreadExecutionState API.

Same here, when my WU finished my pc stays on. A few months ago this didn't happen.

Thanks for your reply, installing it as a system service still does not allow hibernation for me.

In FAHControl, you might want to add client option
disable-sleep-when-active
false
