Windows 8 Refuses to Sleep

[phenley]

My computer will not ever sleep. When I try to put it into sleep mode, all it does is just immediately wake up after it tries to go to sleep.

Is your mouse sensor perhaps dirty and causing slight movement of the cursor which would wake your PC up?

 

Also check your power settings, I'm pretty sure there is one that overrides any sleep settings to prevent it from happening.

[phenley]

It is not the mouse, as I have had many mice plugged into this computer and the same issue has occurred. It also doesn't appear that changing some of the power settings seemed to fix the issue at all.

I had the same issue. My 8 just refused to go to sleep, like a little kid.

 

In my case it was the Samsung Magic software, that came with the 840 Pro SSD.

That thing is a fickle bitch. I quit the program from the system tray and removed it from Startup or wherever it put its entry to keep it from automatically loading after each Windows start.

I don't have that software installed on my system, do it is definitely not that.

I also disabled the Wake on LAN function of my network interface.

 

I normally go there by hitting Win + R, typing in ncpa.cpl and then hitting return

Right click on the network adapter, properties, configure, then last tap to the right with the energy options.

 

[x] Computer can turn off device to save energy

[ ] Device can wake computer from sleep -- sorry, my Windows is in German. I have no idea what it looks like in English.

The Magic Packet option gets greyed out once you untick the second box.

 

You can also check for scheduled events, that are supposed to wake your machine.

 

Open an elevated prompt. Win + X, then choose the administrator command prompt from the menu

powercfg -waketimers

 

It will show you a list of tasks and times.

[Wynter]

Hmm maybe you need to make it tired, sometimes I do nothing all day and I won't sleep either...

 

There's also pills for that :P

Disabling the wake on the LAN function didn't seem to work. I also checked, and there were no wake timers that were set to wake the machine.

[Wynter]

There is a lastwake option that could display what woke the machine up again

 

Try powercfg -lastwake in an admin command prompt window

[phenley]

It says it has 1 wake history count with no wake history or wake source count, which I'm not completely sure what that means.

Sadly it means just that. It woke up but doesn't remember why.

I hoped it would give us a clue.

What motherboard are you using?

 

I know my brothers Zen Book and my sabertooth had a BIOS update avaiable that would fix Windows 8 sleep-mode issues. Look out for that?

I just turn off all the Wake Options in the BIOS to have my System to sleep. Try looking for 'Wake' options in the BIOS. :)

That was it! My Asus motherboard just needed a BIOS update. Thanks!
