Hello Vangel,

I didn't knew the advanced mode in BIOS with F10 followed by A.
I've done some tests, and my laptop (HP Pavilion DV3-4070ss Intel/Ati) 
behaves exactly as yours.
Choosing iGPU is not persistent (i.e. return to hybrid after reboot),
and choosing dGPU you are not able to boot (4 blinks in caps-lock -> 
Graphics)

With test_off (also works) I get the same power drain as with iGPU 
setting (~16-17W idle,full bright,wifi on),
tests with vgaswitcheroo weeks ago give me more consumption when turning 
off ATI by this method.

Some time ago, I read somewhere that for some VAIOS with graphic switch 
present in BIOS, the
BIOS returned back to hybrid after booting Win7, as the computer 
detected the availability of hot switch.

I've played with some bios options in order to try to keep dGPU, but 
with no luck to even boot.
I also want to have the ATI working, as it's the card I've bought with 
the laptop.
