Supervisor BIOS password reset

When I want to install Linux with VirtualBox I get error message. I have to activate the virtualization in BIOS. When I go into the BIOS I need supervisior password, which I have not. I searched and searched for answers long time but can not find any solution to Lenovo x140e. I have been looking for EEPROM but can not find it. Is there anyone here who has any of the same problems. Really need help so I can activate the virtual option in the BIOS.

Thanks for the reply. I screwed all items apart so I can see the whole motherboard. I have been looking with magnifying glass and flashlight but can not find the EEPROM chip. I have taken pictures of the motherboard if you know where EEPROM chip is? I wonder if the SVP may not be stored in the EEPROM on x140e. Thanks again for the answers.

Hi @rashoke

For what it is worth, this is a statement from the service manual for a Lenovo x140e

" Attention: If the supervisor password has been forgotten and cannot be made available to the service technician, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee".

Here is the link to the service manual.

@jimfixer Is the answer to this question: Asking for the bios password of Thinkpad T500 to unlock my computer a solution for "How to remove the supervisor password from ThinkPad T500"?

It's about detaching the CMOS battery.

Can I reset supervisor password of ThinkPad T500 trough detaching CMOS battery?
