Lenovo S730 Bios - results in overheating and fan noise

After I updated my S730 to latest bios, the laptop is overheating when idle and the fan runs at high speed. Any option to roll back bios to see if it changes anything?

Hi Johnny33,


Do you still have or know the previous version? If so, you can enable the BIOS Back Flash in the BIOS settings and install the older BIOS firmware version to roll back to the previous version. To enter the BIOS, please follow the steps here


Let us know how it goes.
