- Clean the pins gently with a dry, soft brush or a toothpick — avoid anything metal or wet.
- Reattach the accessory, making sure it clicks or seats fully and evenly.
- Restart the tablet with the accessory attached to force re-detection.
- Test a different smart-connector accessory if available, to isolate whether it's the tablet's port or the specific accessory.
- If cleaning and testing another accessory don't help, the tablet's connector hardware may need professional repair.
