I connect my Pro Controller to the PC and now this blue light shines, as I feel this light too bright I want to switch it off, so I want to ask you if you know if and how it works.
But that should not burn, that's not feature that is not even unlocked is (will probably be in the future for messages) So mine does not shine when I connect it with the pc, have you downloaded any program, so it works?
No, just connected via Bluetooth.
To the emergency remains only single and simplest solution: Just get a white adhesive tape and stick it on blue LED on it and you should see less blue light.
My light also on pc
That is also ugly on the right side.
But less light
I've connected my cable via my PC, and activated under Steam (Settings → Controller → General Controller Settings and then choose Switch Pro) and since then the light shines even when I take the cable out again.
