Common repair-relevant faults include wireless connectivity/pairing failures (diagnose by re-pairing the LIGHTSPEED receiver, trying a different USB port, or testing wired mode) and button or scroll-wheel faults (diagnose by testing in software and checking for debris or worn switches). Battery charging or runtime problems are diagnosed by testing with the USB-C cable connected, checking firmware via Logi Options+, and ruling out broken charging contacts.
