I don't have that setup, and I am going to assume you mean charging? Look in your manual if you have one, or check out a youtube review on your
device, but most (MOST) manufacturers will use red or some similar color when charging, and then it often changes to green when it's done. The simple solution is to just look at what color the "charge indicator light" is giving you when you plug it in, then what color it turns to after it's charged a while. Some mods use a "bar" to show amount of charge, and again, as I said I don't have that setup, But, I'm assuming that is what you are asking....
Best of luck with it,
