Mid 2012 MacBook Pro shuts down after inactivity while on charger.
Mid 2012 MacBook Pro shuts down after roughly 4 hours of inactivity while on charger. It never turns off when on battery, only when connected to the power adapter. On startup after the shutdown, it will sometimes take 5+ minutes to boot completely, cycling through the log in screen where I can't move the cursor or type anything, to a black screen, and finally back to the log in screen where I can finally log in.
