|I think I just figured out how to do it... |
This option was hidden within the power saving setting section.... If anyone else wants to know the answer I went to Change the setting in my power plan, selected change plan settings under the plan i had selected, then Change advanced power settings. When that came up I expanded 'Require a password on wake up' and changed both on battery and on plug to 'yes'
IT WORKS! (= Yay me!
