supervisor password Lenovo Thinkpad x270

[Stedny]

Hi, I bought a Lenovo Thinkpad X270 used 1 year ago. And now I need to run Elsawin in a virtual disk. Then I have to go into the bios to change something that I can't change without a supervisor password, I have tried removing the battery and cmos battery without success. Does anyone know how to do it without sending the machine in? I'm new here and I really appreciate the help I can get. Regards Stedny
