A few weeks ago our TiVo box stopped going into energy/standby mode at night when switched off. Every morning we wake up and it's on and using unnecessary electricity.
At the moment our setting is at
Snooze, with Suggestions turned off – after being idle for 4 hours, your TiVo box will enter standby, Suggestions will not be recorded. This means you're running your TiVo box energy efficiently and speedily.
My husband is up at 6am and it's still on at 6.30am so he switches it off.
