Forget BIOS Password Lenovo U41-70 80JV (Phoenix BIOS)

Hello Lenovo Community,

  I have a Lenovo U41-70 80JV. It was a birthday gift from my friend. I have been using this laptop for 2 years already. For some reason, I had a BIOS password in my computer. I was lucky that I don't have to type the BIOS Password while powering on the computer. I need to change my boot options but I cannot get into BIOS. Here is what I have tried so far:
- Use cmospwd-5.0 -> Command Prompt -> ioperm.exe -i -> StartService function call failed

- Use Master Password -> Failed

- Use -> BIOS doesn't show error code

- Kill CMOS Battery -> Waited 30 minutes -> Failed

- Pull out jumpers -> Do not see any jumpers

- Use KillCMOS3.0 -> Killed -> Password didn't reset

Someone told me to use dip switches but I cannot locate it because I don't have an exact picture of it

Any help, thanks!

There is no reset or backdoor password.  The choices are to remember the password or replace the motherboard.
