I have bought two Inspiron 7610 recently. I have the problem that one of them powers on automatically a once a day.

This is not an issue with the operating system or external devices. The new SSDs are completely empty yet, no OS installed. There are also no devices attached except the power supply. 

Every morning, I see one Inspiron 16 powered on like in the photo. This is for 5 days now, without doing anything with them (except switching if off again).

I am seriously worried that it can power on automatically when travelling and I have this laptop in my suitcase or bag, which may cause fire.

Did anybody experience the same problem? This happened 5 times now in 5 days.
