You need to contact Lenovo for support with THEIR laptop.

Also, did you confirm with Lenovo that the i7-3740QM was supported by THEIR BIOS?

Updating the bios can only help if the new bios supports the new processor.

You must contact Lenovo regarding this. Also, do not believe sites like those in the link you posted.
