Owners of the Lenovo Legion Go are encountering a critical issue with a recent BIOS update, version N3CN42WW for the 8APU1 model, which appears to be rendering the handheld gaming PCs unusable. Reports on platforms like the r/LegionGo subreddit indicate that affected devices are experiencing black screens and failing to recover even with the BIOS self-healing function. Moderators on the subreddit have begun advising users to refrain from installing the update.
Despite these user reports, the problematic BIOS update has remained available on Lenovo's official support servers. The full scope of the issue remains unclear, and it is not yet known if all Legion Go units are susceptible.
Compounding the problem, users whose devices are no longer under warranty are allegedly being quoted repair costs exceeding €237 (approximately $273 USD) by Lenovo. For devices still within their warranty period, Lenovo is reportedly continuing to offer free repairs or replacements. Some users have opted to pay to reactivate their warranties to ensure their devices are repaired by the manufacturer.
While Lenovo has not yet released an official statement or advisory regarding this BIOS update, some users have attempted to resolve the issue through non-standard methods, including direct SPI programming. Third-party repair services are also reportedly investigating potential fixes.
For current Legion Go owners, it is strongly recommended to avoid installing the N3CN42WW BIOS update. If your device is experiencing problems and is still under warranty, contacting Lenovo support is the advised course of action. Alternatively, users with affected devices might consider reverting to the previous BIOS version, N3CN40WW.
