Hey there, Have not turned on my Wii U for about 6 months now and I just went to power it all back on. I tried turning on the controller and nothing. I found its charger and plugged it into the controller directly, no charging light even after waiting an hour. I then used the dock to try charge it and still no charging lights. I heard you could test if its the battery by removing it and putting the controller on charge which would blink the orange light due to no battery, when I do this there is no flashing light. Is my controller completely dead? is there a way to resurrect it? Thanks.
