IdeaPad Z500 Bios Recovery

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.

Hi VegetaOSX,


Welcome to Lenovo Community Forums!


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.

Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.


Do post us back for further queries.


Best Regards

Shiva Kumar

Re: IdeaPad Z500 Bios Recovery

This is probably not related but can’t figure out how to start a new post! My Ideapad 300 is asking for recovery media. Is this something I can download from net so I can re boot? Thanks in advance
