Acer 7720G Bios Password Reset

Question

Hi, i was fiddling around with the laptop last night and i came across some password setting for use to boot up bios. I don't think i went through fully with it and should have cancelled it but when i switched my laptop on today it requested for a password which i have no recollection of inputted into. What should i do? Can i call Acer and get them to generate me a master password?
