BIOS update mistake

2021-07-11, 9:30 AM

I was trying to enable Virtualization in BIOS settings and by mistake, I may have set the BIOS to default. Now the BIOS version is showing 'LENOVO JBET54WW (1.19), 11/6/2015'. After this update I believe, laptop is behaving weird. My battery is draining when the lid is closed overnight and Laptop is getting heated up. (Power Options are set correctly - Lid Closed - Sleep) I know battery is good and it is a new one. I do not face this issue while I am working on battery. Question:

How do I know what was my previous version of BIOS ? Is there a way I can revert back and how.
