Bios Mods -The Best BIOS Update and Modification Source

Hello,

I have laptop ASUS X555LJ.

I saw here some tools to unlock bios, but i have no idea (not sure) how to do this, and surely, i am afraiding to break down my device.
I just want switch to discrete videocard and control ACPI, but it would be nice if you will unlock everything.

please, help me.  

Bios 602: http://dlcdnet.asus.com/pub/ASUS/nb/X555...1500135298
(AIDA64 report required?)  

Thank you!
                Best regards, 
                                   Taco.

Bumb!

Hi I also have this laptop and i wanted to unlock the bios to have my processor undervolted at all times and to use an e-GPU in the future.

if anyone can make this happen i'll be more than happy to give any report or file needed
