    S3 Sleep unavailable


    After reinstalling Windows 8, i can't configure my computer to enter S3 sleep mode after 2 hours of inactivity.

    When going to Power Options, the options called "allow hybrid sleep" and hibernation aren't here anymore

    what to do ?

    Hello Anarchoi,

    Double check using the tutorial below to make sure that you have hibernate enabled. Afterwards, see if those options are available in your power plan again.

    Hope this helps,

    Oh, i deleted hiberfile.sys, that's probably why. Will follow that tutorial and see if it gets it back working. Thanks.
