The advance tab seems to work fine, thanks! But when I enable the integrated graphics card via this tab the screen go black and I need to reflash it. Is impossible to make the integrated graphics to work or there more things to do?

1. That new button is Chipset tab , i will give you another mod later to unlock Advanced tab.

2. Why you need to enable integrated graphic?? It should is enable by default if this laptop has designed output circuit for integrated graphic.
If not , it means that this laptop only has independent graphic(nvidia) output ,so when you enable integrated graphic in bios ,it will get a black screen.


Or you could tey set Primary Display to IGFX and enable Internal Graphics to test again.

Sorry, I send you the wrong photo. This is the correct one. I need the integrated graphics since the dedicated makes the baterry duration horrible. And I need for hackingtosh either

As i mentioned at #6 ,if it still can't enable igpu after some settings change ,it means that this machine don't have design integrated graphic output circuit ,so it's impossible to enable. It's an hardware restriction.

You can ask to the support center.
