Complaint USB port not functioning properly. Cause Most reported USB port issues are due to improper use or contamination. Note: Any repair costs must be discussed with the customer beforehand. Common external factors identified include: • Fluid intrusion • Broken bushings or physical damage See attachments. Remedy If a component needs replacement but shows no visible external damage, submit a detailed TIPS case only when technical support is required. Include details of all connected external devices (such as charging cables, USB drives, and hard drives). If diagnostic results directly indicate component replacement, a TIPS case is not necessary.
