I was messing around with my laptop, When i can upon a password for the harddrive, So i entered a password and confirmed it then went to enter it once it asked me and it wouldnt accept it, Here are its words:

'Please Enter Master User Password:'

I went onto my motherboard and taken the battery out and left for a while but that never worked does anyone have any ideas please

So im locked out my hard drive !!!! and can not get onto my laptop
