Windows 10 PC goes to sleep mode too frequently

[BetaTime]

I'm running Windows 10 on Dell Alienware and I've disabled all screen savers, screen is set to turn off at 15 minutes and "sleep after" is set to NEVER! I did that from "Power & Sleep" settings as well as from "Advanced Power

settings" panel. But still my PC goes to sleep within few minutes of idle time. It is not consistent with it the idle time either... sometimes it happens around 3 minutes mark and sometimes it takes about 30 minutes.

 

 

 

This time I captured the event logs and here is what i found:

 

 

 

The system is entering sleep.

Sleep Reason: System Idle

Source: Kernel-Power

Keywords: Microsoft-Windows-NDF-HelperClassDiscovery,DCStop

 

 

And the previous 3 events were:

 

The driver \Driver\ACPI for device stopped the power transition.

 

Reason code is 'Idle'... but the system was idle for just 3 minutes!!

 

Searched for solutions and everywhere people were talking abou trivial stuff like "check your screen saver", "check your power settings", etc. But in this case, all seems to be good and the PC set to NEVER sleep, but it continues to do

the same. Please let me know if there is anything else I should check/set?! Thanks!!
