So I bought a Toshiba Satellite C850D from somebody off Facebook. I didn't check to see if it worked, but I got home, charged it I went to turn it on and it is asking for a HDD/SSD Password. I have no idea what the password could be, and now I can't get ahold of the guy I bought it from. I realized I fuc**d up. I've tried to bypass it by using the 0 key, F8 key, and ESC key. Nothing works, it just beeps then asks for the Password. I'm trying to see if there is any other way to get around it, or factory reset the computer. Anything to where I can use the computer.
