Any solution?

Тhe resolution of the matter is entirely up to you, the second dump is just as good as the first. All programs including the autopatcher return an error with it.

AUTOPATCHER is not working on this Lenovo laptop!

here is a solution to unlock L450 BIOS.
For safety reasons make dump backup and take care during security chip shortening. Make also picture on bios SERIAL number and so on (just push enter when as for password to go inside locked BIOS).

1. Prepare something to short circuit SDA and SCL line of security chip.
2. Remove hard drive.
3. Switch on laptop and immediatelly shortcircut this 2 lines, as on picture.
4. When laptop will show error with laptop serial and so on take press F1 to enter to the bios. Take out shortening tool. Don't worry if you won't see serial number and so on for now.
5. Go to supervisor password and just press enter two times to save empty password.
6. Go to last page and click SAVE & EXIT.
7. Switch off laptop and then switch back on, push enter and then F1 to go to BIOS and VOILA. Password has been deleted. Laptop serial data shall be returned.

Say thank you if this helped
