I noticed that when I step away even for 10 minutes, my PC goes to sleep, and I have to renter the password each time. I went into the settings and changed both turn display off and put PC to sleep to an hour, but still, a few minutes later, it goes to sleep. (The power light is flashing and the fans are off. When I press the power button everything kicks on and I have to login again). It's really just annoying.
