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
