Several Lenovo Legion Go owners are facing a critical issue after installing the N3CN42WW BIOS update. Reports indicate that the device hangs with a black screen and fails to boot properly. The problem seems to affect both Z1 and Z1 Extreme models, collectively known as the Legion Go 1. The exact scope of the defect is not yet clear, but moderators of the LegionGo subreddit have issued an explicit warning for users to avoid the update until Lenovo clarifies the situation.
Failure symptoms range from immediate boot failure to gradual performance degradation
Some users have reported that their Legion Go stopped working immediately after the update, while others have noticed a progressive decline in performance over time, including controllers becoming unresponsive. This variability makes it difficult to pinpoint the exact cause, but the severity is such that community moderators advise against updating the BIOS unless you are willing to assume all risks. The message posted on the LegionGo subreddit also asks anyone who encountered the problem to share their experience to help understand the scale of the issue.

Out-of-warranty repairs exceed $270, and not everyone can afford it
A Reddit user, identified as mherold11, contacted Lenovo support to repair their Legion Go, only to find out that the device was out of warranty. The quoted repair cost was €237.16, roughly $273.81. Other users in the same thread reported that if the device was still under warranty, the repair was completed at no cost. Another user managed to repair the device on their own, but that solution proved complicated and is not recommended for most people. This case highlights how a routine BIOS update can turn into an unexpected and significant expense for those without warranty coverage.
