I usually leave it on in the day time, but when I go to sleep I am 100% sure I turn it off not to loose charge on battery when I'm not using it. But every morning when I take it off the lid, the thing is POWERED on AND RUNNING! First couple nights I thought maybe I'm wrong but I try it every single night and it just powers on, I wonder if it does that on a specific time? That's what I'm thinking now, maybe it has like a specific time set to it to power on?? I will start to check it whenever I get up from my sleep each night to see if there is a specific time that it does that ) I will be watching this Thread for a possible solution, I have the latest firmware(I believe April)
