[onyxbooxmax3]

When I power off my onyx boox max 3 the blue led on the power button keeps blinking.
There does not seem to be a way to completely power down the device in its stock configeration.
I did consider rooting the device and installing a power off utility from f-droid or google play but the process for rooting still looks pretty speculative to me.

Is there something I am omitting when I try to power down the device completely.
The battery life in the supposed power down state is of the order of 36 h which suggests to me that it is still drawing significant current in its appearent off state.

Thanks
