Let's look into this Power configuration concern. You can disable Connected Standby via the Registry. We encourage that you Backup your Registry before proceeding with the changes. Navigate through the registry by expanding these Keysets: HKLM > System > CurrentControlSet > Control > Power > CsEnabled. Change the value from 1 to 0 and restart.
HKLM\System\CurrentControlSet\Control\Power\CsEnabled (1->0) (change from 1 to 0 and restart)
Update us if changing these values will rectify concern.
