Plug it in. Do you see the same thing?
I took my chip out of my Mini a while ago and installed it in a diy dual cell box. Not sure if the v1 chip just doesn't want to charge 2 cells or it didn't wire up to charge but plugging it in doesn't do anything. I wouldn't charge in a dual cell mod without a balancer anyway so I didn't care. I didn't charge in the single cell Mini case either.
Hke, you can't select system on/off in the menu? If not somethings up with that chip but if it's more than a couple months old you are probably past the warranty. Not the end of the world I guess as long as it still vapes well regardless of the charge indicator. Not sure I've ever turned mine off in the menu, if it's in rotation, batteries are in it and if it's on the shelf batteries are in a storage case.
So that charge or dongle indicator or whatever it is is there whether you are Charging or not?
