how do i turn off fingerprint scanner (acer tm2330)

i am working on an acer travelmate2330. Some pot-smoking monkey who calls himself a technician thought it wise to put a bios password and protect the laptop with the finger print scanner (his own).My client is an old lady who wants nothing to do with this smart Aleck anymore! I have rummaged around the internet left right and centre and still can’t find a solution. Help
