Question "Sleep" option not showing in Windows 10 ?

[Reepe3]

I have tried every option available on google and tried forums advices which all did not work.
What's left for me to try to fix sleep option missing is entering bios mode. Unfortunately i don't know my bios settings since it is different from other bios settings.. mine is Aptio Setup Utility and I wanna ask if someone here knows some setting to enable sleep mode in Windows 10 ?

My specs
intel e5-2640 0
X79G AMI
GTX 1050 Ti 4Gb
16gb Ram
500Gb Samsung SSD

Did you try this ?

Start => Settings => Power & Sleep => Additional Power Settings => Choose what the power buttons do

If you don't see the Sleep option, continue to "Change settings that are currently unavailable", if you see the Sleep option just check the box.
