If putting on interval (say 1 min) with liveview on, then go to powersave and turn off display after 5 seconds. The display willl then turn off after 5 seconds, but then it will turn on again within 5 sec to show the modul console semi-transparent.
Within liveview I can't make powersave to work at all - it only shows the modulconsole. No difference if changing to silent pic.
Workaround: The only way take timelapse with power save is to exit liveview. To get rid of the console you then have to turn it "on" and then "off".
