Likely some task is running in the background, waking it up every so often. You can open up a command prompt and run it as administrator, then type in "powercfg -lastwake" without the ""after it was woken up. It should show you what woke it up.
In the last month, my Aurora R11 has not been consistently going into screen saver / sleep mode. The settings are as I left them, 5 minutes for screen saver, 20 for PC sleep mode. I'd say about 50% of the time, the PC remains "awake" after I walk away from it. Any ideas what the issue is? Thank you.
