Migliaccio & Rathod LLP is currently investigating widespread reports of USB port failures and microphone detection issues affecting the Lenovo ThinkPad T14 Gen 3 and T14s Gen 3 laptops. Users report that USB ports stop functioning (no charging, no data transfer), and internal microphones disappear from device settings, even after clean OS installs and updated drivers. Many have found Lenovo repair services to offer inconsistent or temporary fixes.

Affected customers have tried multiple troubleshooting steps with little or no success:
-
Reinstalling Windows or updating firmware often provides only short-term relief
