PC not going to sleep

[kelvinhall05]

Ever since installing F@H, my PC doesn't go to sleep. Unless I shut it down or restart it (even after restarting it doesn't always sleep), it will stay awake forever. Thoughts? I pause it when I go to bed because the fans on my GPU are loud and I don't want to listen to that all night long. Thanks!

I haven't used Folding at Home myself. but from my understanding it runs in the background of your computer to run the simulations. So if your computer is off/asleep it can't fold. so the program keeps it from sleeping. I would check to see if there is some kind of settings to turn off. Or just uninstall it or close the program so it will go to sleep.

Kinda an odd solution, but try hibernating it instead. The option is hidden by default but instead of saving what you were doing to ram, it saves it to the HDD and shuts the machine down, loading your session back in to ram once it boots back up. Waking and sleeping will take a bit longer, but this was usually my solution to PCs that wouldn't behave

F@H

 

When a CPU sleeps, the current state of the CPU is saved. Resuming a CPU assignment after a sleep should always work. The current state of the GPU is NOT saved, hence resuming a GPU assignment after a sleep would frequently fail.

 

F@H therefore when using GPU folding will not let computer sleep. 

 

As mentioned above hibernation is next best answer as it will save GPU and CPU states to HDD. 

 

Another answer is uninstall

But hibernation isn't like a shutdown, just a "deep sleep"?

When you sleep, whatever you're doing is saved to ram. When you hibernate, it saves it to ths HDD instead. I use this on my laptop because hibernation takes zero power, the system is literally off

Well I guess that rub for you to work out.  What option is best for you.  I given you why it happens. I cant change why it is that way.

 

I gave you how it works and why. believe me or not idc.  The Video RAM is not saved in sleep and is flushed on resume and this is the issue. F@H elected to stop sleep if GPU is used.
