Steps to Update BIOS Safely
Follow these steps carefully to ensure a smooth BIOS update process on your Lenovo Yoga.
1. Prepare Your System
Make sure your Lenovo Yoga is plugged into a power outlet. Do not attempt to update the BIOS with a low battery level, as power interruption can corrupt the BIOS and brick your device.

5. Wait for the Update to Complete
The system will automatically restart during the process. Do not interrupt or power off your device until the update completes and the system restarts normally.
