Razer blade pro RZ09-01662 4k model serial number missing in bios an new battery not charging

Basically simple as that....the serial number is missing from the bios idk how that happend an all of a sudden my new battery a few months old went from charging to just not doing anything....it says its stuck at 25 percentage then if i unplug the cable it dies instantly...also since the serial number is missing for some reason i cant use the razer updater as it says my system isnt a razer..... apparently you can insert your serial number an sku through amidewin but i dont know how
