    This is a separate I/O board and it might be that the service center has not connected it properly to the MB. Check if the flex cable is connected on both sides and if yes then mignt be that the I/O board is defective. Provide please the exact model so I can share the  spare P/N with you.

    The light is connected with the charging port and has separate cable. Only you can know if the I/O board was replaced, all I got from your post is that the MB was replaced.

    If you have warranty call them again and let them know that the repair was not done right
