Migliaccio & Rathod LLP is investigating reports that Legion 5-series laptops suffer from USB-C connectivity issues, including intermittent failures to enumerate devices, provide power delivery (PD), or output video. Affected users have reported that these problems often occur unless paired with specific adapters, and efforts to resolve the issues with EC/BIOS updates or daughterboard replacements are sometimes only temporarily effective.
Common USB-C Problems Reported by Legion 5 Owners
Users have experienced various USB-C related issues, including:
-
USB-C not charging or providing reverse power via Power Delivery (PD)
-
Monitors not detected over USB-C (DP Alt-Mode) or unstable video output
-
Devices failing to enumerate properly unless using specific hubs, adapters, or cables
-
Temporary relief after firmware updates or hardware swaps, followed by a recurrence of issues
These issues indicate potential design flaws or compatibility problems with the USB-C ports on the Legion 5 series.
Service Visits Yield Inconsistent Results
Many Legion 5 owners report repeated service visits and cable or dock substitutions as attempts to resolve the issue, but these fixes often provide only partial or short-lived relief. Firmware updates and hardware replacements have yielded inconsistent results, leading to significant frustration for users who rely on USB-C for charging, data transfer, and video output.
