I just upgraded W8 to W8.1. When power is connected I got auto sleep disabled. Whenever I manualy put computer to sleep then after wake up it keep sleeping in like 3 minutes.
It doesn't matter what is set in power options windows. It fall asleep in the short period if there is set never or ten hours.
I remember that I got this problem with windows 8 and after weeks of googling I found a solution where I needed to change something in registry. Do anyone know how to fix this problem?
