Need a rescue password please

My tablet was stolen and recovered, but a BIOS password was put on it by the person who took it, so when it starts up, the password screen for the BIOS comes up before it even boots to Windows. I found a way to toggle so I can get to the screen where I can put in a rescue password in, so I need a rescue password for 2016-02-17 (or whenever this gets answered). Please help!!
