How to backup BIOS?

Question

I will be repasting my Dell XPS 15 9570 notebook's CPU/GPU. This involves keeping the battery disconnected during the procedure, will this erase the BIOS settings? If so, is there any way of backing up the BIOS settings so to restore them afterwards other than maybe taking screenshots of each BIOS page? Thanks

Welcome to the Communtiy. Once you have updated your Bios you will Not be able to reverse back to the old version of the Bios. Check with Dell Support Center if you require the Bios update.
