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?

thank you. i recently update my lenovo chipset bios. but still have that problem.

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.
