What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleName the failing app, game, host or connection and one context that still works. Expected behavior: charge and report buttons while attached and pair wirelessly when removed.
Isolate the component boundary
ReversibleCompare attached and detached input, update controllers and inspect dry contacts. Swap only the app, host, profile, cable or wireless connection while keeping the accessory unchanged. Boundary to separate: Joy-Con versus rail contacts, battery, wireless interference and controller firmware.
Correct only the proven cause
ReversibleRe-pair or service the rail/Joy-Con that fails in both states. Repair the isolated app, profile, codec, port or compatibility boundary.
Verify and stop safely
ReversibleRetest the failing context and one known-working host or app. Stop for swelling, liquid, heat or bent rails.
