yes its normal, Yes I have dozens of laptops, yes I see the same thing... look at the image, if your settings are grayed out like mine then that is what is happening at your end i.e, the power setting is set to override normal use because your system is always on charge
if you have an older laptop i.e, one not designed to run Windows 10 then you will get the default power settings but assuming you do allow updates it should get around to asking you about power... laptops are not designed to run on leads at all time and its not good for the battery to never be charged or just always be on charge
in any event power settings are a Windows thing, not normally your Bios so if you need more help please give us the make/ model of the laptop and a screenshot like the one i posted so we can see
