Lenovo Yoga 520 14-IKB 81C8 RTC problem

The latest BIOS update v2.09 41qc45WW cause the Clock to run slow. I need to downgrade to v2.07 to fix. Please fix the problem

Hi jojojmtk!


Welcome to the Community Forums. 


Access BIOS first and check if there is an option for BIOS Back Flash. Image below.



If so, enable it then save and exit changes. Make sure you have the V2.07 .exe version then install it inside Windows.
