hi guys. just got myself a N55SF and did a reformat and clean install of Windows 7 Ultimate. Few questions from a n00b here:

1) I've reinstalled Intel HD graphics (d/l from Intel website) and latest 285.27 nvidia beta notebook drivers. how do i know that optimus is working as it should be? there is no indication at all....just a intel HD graphic and Nvidia settings icon in the taskbar.

2) where can i get the Asus E-Driver utility? i can't seem to find it in the asus download page.

3) how do i install the Intel Management Engine Interface driver?

cheers.

1) thanks for the info.
2) i dun think a disc was given with the N55SF. i did make the recovery discs b4 i formatted. is it in there?

where can i d/l the Sonicmaster driver for the N55?

that driver looks like it's just audio drivers from realtek, which i have already downloaded from realtek's website. i thought that there is a separate driver just for Sonicmaster?
