qBittorrent official forums

I recently switched over from uTorrent. I have a question. When I'm seeding files, it seems like they only seed while the computer is active. When I go to bed, they may show they've been active for 4 hours. When I come home from work the next day and check, it shows something like 4.5 or 5 hours.  They're all fairly consistent in this, allowing for files with no leechers.  Any ideas?

Options - Behaviour - Power management: Inhibit system sleep when torrents are active.

I found that option and enabled it, but it doesn't seem to have helped.

Then turn it off directly from your OS settings. Disable hibernation, turning off disks, etc.

I guess I can if I have to. uTorrent never gave me a problem with this...I might look around and see what other torrent programs are available that don't have this problem for me.

I'm not sure, but i think you're the first with such a problem.
Let see if the others have some ideas.

There is issue #766 posted about a month ago in the github issues forum that sounds the same "Despite ticking "Inhibit system sleep when torrents are active" the system continues to go to sleep."  I added a comment to that thread as well.

So, is it sleeping or hibernating or is it rotating the torrents i.e. torrent queuing?

No, not queuing. The computer is set to go to sleep after 30 minutes.

Actually, you can leave disk spin up/down wherever you're comfortable, if a seeding torrent' data is requested it'll spin up the drive as needed and begin uploading (mine does at least) plus it still counts as seed time if the disk is spinning or not, but as suggested so far it is probably best to disable system sleep from the OS... that way at least it's not the programs' fault.
I have my system set to never sleep (100% uptime) except for windows updates and prolonged power loss. Therefore I obviously never came across this problem.
