Lenovo Z570 BIOS Firmware 45CN47WW issues

Hi! Just change the motherboard (system board) the new one came with BIOS Ver. 45CN47WW from 2012.

Can Lenovo confim its offical and its ok to use it? Swithchable graphic indication in system try not showing.

When plug usb mouse the touchpad won't turn off, even is checked "when attached external usb automa....adn so on"

Tried with windows registry no effect, tried with uninstall/install synap.driver no effect, tried, uninstall/install Lenovo Power Mang, no effect,

same with graphic drivers/

Shall I rollback to previos BIOS ver. 45CN38WW from Lenovo offical support page? 

 

p.s. I can't find it anywhere on Lenovo Support, Lenovo Download, etc, just found it in one forum for Linux.....
