Hi, I updated my BIOS to the latest version available, 1.18. However I have some serious issues with the fan. It's not stable. How can I do a Bios recovery, or go back? Where can I get the previous version or factory bios version of my laptop? IdeaPad Z500 Notebook. Model 20202.

I’m sorry to inform you that after updating the BIOS it overwrites the current version with the new version and is not reversible unless you had made a backup of the previous version, as an alternative I would Strongly Suggest Calling Technical Support for Assistance.
