By sleep mode, are you saying that during this time, the tracker is unable to notice that your walking and doesnt count any steps?
Also mentioning that the Blaze only works in its charger, seems to point towards a defective unit. My suggestion would be to contact fitbit, and have then take a look at the tracker from there end.
I say this because the Blaze is not suppose to have a sleep mode of this type.
