Lenovo says it is ‘clear’ Legion Go faults ’not user error’ and even devices out of warranty could be repaired ‘free of charge’
Lenovo has acknowledged that a critical BIOS update for its Legion Go handheld gaming device is causing serious failures in certain units. After installing BIOS version N3CN42WW, affected devices became unable to boot past the BIOS screen, effectively bricking them. The issue has persisted for several weeks, drawing complaints from users.
The company confirmed via its forums that it successfully replicated the bricking problem across three test devices, establishing that the fault is not due to user error. However, other Lenovo teams were able to apply the same update without issues, suggesting the problem is linked to specific hardware batches rather than a universal flaw.
In response, Lenovo announced that all affected devices will be repaired free of charge, including units outside their warranty period. This represents a substantial gesture of goodwill from the manufacturer toward users affected by the defective update.
The company indicated that the root cause appears to be related to specific components used on certain mainboard batches, rather than the BIOS update itself. This component-level variation suggests the bricking issue impacts only a subset of Legion Go units from particular production runs.
