Common repair-relevant faults include wireless connectivity dropouts, depleted or non-charging battery, and unresponsive buttons; first diagnose by re-pairing the receiver, testing with a fresh/charged battery, and swapping USB ports. For button or scroll failures inspect and clean the sensor and switch areas, and check for visible damage to the housing or internal cabling. If firmware-related behavior occurs, verify Logi Options+ connectivity and check Logitech support for firmware guidance (support page notes many resources are not available).
