Windows 8 Pro goes to Sleep after 60 seconds of inactivity

I just upgraded via clean install to Windows 8 Pro. Now the computer will go to sleep / standby after 60 seconds of inactivity. Interestingly, this behavior only occurs once the machine has already gone to sleep once in that power cycle. In other words, if I start from a cold boot, the machine will follow the power plan appropriately (screen saver after 10 minutes, sleep after 2 hours) until it has gone to sleep once, after which it will go to sleep every sixty seconds of inactivity. 

The system event log shows "Event 42 Kernel Power : The system is entering sleep. Sleep Reason: System Idle." But it does this after just one minute of idle. 

I have reset all power plans, I have created my own power plan. Hybrid sleep is disabled. I have run system file checker (sfc /scannow) and I have searched the forums extensively without an answer.

This is a custom built desktop machine which never previously had this issue on Windows 7, it is a new behavior to windows 8.

So after a lot of digging and trying many things, the below solution worked for me. But if someone can verify this worked for them, that would be great:

It seems like maybe Windows is viewing the return from sleep as a remote wakeup which apparently times out to idle faster than other wake ups. To change this function, delete the following registry key: (maybe using the power button to return to sleep as suggested would be a work around?)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0\DefaultPowerSchemeValues

To do this, Win Key + R (brings up the run menu), then type "regedit.exe" and navigate to the key location listed above. To be safe, you should save (export) that key before you delete it.

Alternatively, you could edit each of the sub-keys instead of deleting them. Each corresponds to one of the power plans. If you choose ACSettings you are choosing a behavior for when the machine is plugged in, DCSettings are for battery power. If you edit the key, switch do "decimal" The value listed is in seconds, and can be changed to any value you choose.

Hi, 

It worked for me, thank you!

had the same issue with Windows 10 (Built 10162) on my laptop. I have removed all the registry folders under the ...\DefaultPowerSchemeValues.

After a reboot the issue has been  disappeared.

    REPLY TO eClift: That is the first smile I've had on my face in a long time after reading your reply to 7th_son's post on March 6, 2013! It actually made me laugh out loud! It is now May 12, 2016 and I'm having the same problem on New Dell XPS 8900 desktop upgraded to windows 10 pro 64 bit. I can appreciate the gentleman's info on the registry fix, However I am COMPLETELY EXHAUSTED from all the reading, and changing, and reading and trying! And truthfully, I'm so over it! I shouldn't have to tweak the system! Not to mention their are some folks like me that occasionally get weak in the knees when it comes to changing stuff ...especially in the registry! ****! It looks like I'm on my own! Hope I don't screw it up more than it already is???
