Lenovo is aware that some Legion Go devices may experience a blank screen during installation of BIOS version V42. BIOS V42 was not distributed through Windows Update or Legion Space, and Lenovo has removed the update from its support website while we continue our validation work. Users who have successfully completed the V42 update should not need to take further action at this time.
If a device encounters a blank screen during V42 installation, users may try pressing and holding the power button for approximately 10 seconds, waiting approximately one minute, and then powering the device on again. If the device does not resume normal operation, customers should contact Lenovo Support for further assistance.
Lenovo continues to evaluate and validate future BIOS updates for Legion Go.
