The Asus K55A-Si50301P USB 3.0/Audio port Replacement Guide explains the tools and processes used to replace/remove the board as needed. A USB/Audio port may occur to be damaged/faulty when general hardware malfunctions cause an inability to use the port properly or when the port has sustained physical damage rendering it unusable. A USB is not working properly when a device is unable to plug into the port in the correct orientation or will plug in and yield no results. An audio port is not working properly if the jack cannot be fully inserted or sound cannot be heard. The Asus K55A-Si50301P Troubleshooting page may be referred to here as needed.
