since I am too lazy to check my power options (and I like them to be always on, else I will have to change them everytime I will use or not use Lumion), I just open the Windows Media Player and let it play, endlessly, some relaxing music. I can even turn the volume down. The WMP stays on the background playing music while Lumion renders, and with WMP playing music, Windows DO NOT lock or turn off.
