I noticed strange thing.

I hear not loud but typical electric current noise - like from AC/DC adapter which comes from insde of my laptop G56
It's unpleasant.. When you put your head close to the chassis then it will be louder [especially when fan is off]

When I unistall nvidia or intel graphic this noise disappear....

is this normall? or I have something wrong with chipsets ?
Do you hear the same in your laptops ?

I'm not sure the sound you are referring to. I'm picturing something like this?

If so, then that definitely isn't normal. I've never heard it in any of my laptops or desktops

ha ha ha no no no :) it's 1000 times more quiet. You can hear it only at night, or when you put your ear close to chassis. i can compare it with working HDD 2.5'', but I have SSD :)

it's a little annoying because this is high frequency noice...

what its interesting the laptop is completly quiet ..no sound like in vacuum when I have unistalled nvidia or intel graphic driver :) probabyl the noise comes from memory
