uTorrent prevents computer from entering sleep state

I've been using uTorrent for a long period of time, but recently I noticed that when I open uTorrent, I can't make my laptop go to sleep. The screen turns off and etc. but it will be still running and I should hold the power button to shut it down.

I also tried exiting it and no difference. I tried stopping all torrents and then exiting it, no difference. (and by "exiting" i really mean exiting, not just closing the window!)

I searched about this and only thing I found about it was this and as you can see, no real answers.

I also tried unchecking "Prevent standby if there are active torrents" in settings. Didn't work!

And this is what I get when I use powercfg /requests in cmd:

DISPLAY:
None.

SYSTEM:
[DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0269&SUBSYS_104311A3&REV_1001\4&2d8ce5ba&0&0001)
An audio stream is currently in use.

AWAYMODE:
None.

And it is the same before and after opening uTorrent.

Any solutions would be highly appreciated :) Thanks in advance.

From your comments, it seems that µTorrent has not fully closed when you try to suspend. This is an expected default behavior, since µTorrent has the bt.graceful_shutdown option activated by default. This option, as you can figure:

Graceful shutdown is for when torrents take too long to write, normally µT will close in 10 seconds, with graceful shutdown, it wont close until all the data is saved.

Meaning, that µTorrent hasn't ended writing up all the data to the disk (they are still in the Windows cache) and since you have a Laptop with slower Hard Disk, this could take a while.

You can disable this option going to Preferences > Advanced > bt.graceful_shutdown and set it to false. WARNING: This could provoke that your torrents/data gets corrupted, so it's better to wait until µTorrent finish up.

If you are going to suspend after you finish, why not let µTorrent to do so?

µTorrent has a feature to automagically do actions when all downloads (or downloads/uploads) are finished. One of this (as you can see in the screenshot) is Standby when Downloads Complete, which you might find very useful and secure.

Go to:

Options -> Preferences -> General -> Prevent standby if there are active torrents

Make sure this is unchecked.

If this wont work,

Go to BIOS: Disable: "Wake up on LAN".
