Early 2011 MacBook Pro does not standby correctly My Early 2011 15" MBP non-retina will not enter standby mode correctly. Meaning, when inactive for a few minutes, rather than just turning off the display, it goes into sleep mode, causing network shares to disconnect.

I have the Energy Saver settings set to never sleep while on power

This is a big problem for me, since I use NAS shares to store much of my work.

Is there a way to either
A) Disable sleep mode while plugged in (because usually when I need the shares up I'm plugged in) OR
B) Configure macOS to keep AFP shares connected while in sleep mode

I am running 10.13 High Sierra Beta
