Is it possible to disable an external graphics card using nVidia Optimus (Asus ux32vd)?

Question

Iron

I have been looking for an ultrabook for a long time, and finally I decided more or less - I will take Asus ux31a or ux32vd. The choice is complicated by the fact that each of the laptops has its pros and cons. One of the differences is the presence of an nVidia GT620M video card in the ux32vd model. For me, the presence of an external video card is rather a minus, because. I need a laptop for work, and integrated graphics would be enough for me with a large margin, and a discrete card in this case is just an extra consumer of energy and a source of heat.

In this regard, the question arises: Is it possible to disable an external video card using nVidia Optimus (Windows OS)?

As far as I know, under Linux, the external card can be disabled with Bumblebee, but what about under Windows?

If there are owners of Asus ux32vd, tell me if there are any settings for managing video cards in the BIOS?

Answer 1

Asus seems to have any laptop with an nVidia video card that can disable the external one, of course, if there is something to work without it;) (that is, it requires a built-in one).
I do not have an ultrabook (ASUS K43SV), but the external video card is turned off easily by changing the power plan.
At the same time, battery life increases from 2.5-3 hours to 4.5-5, provided that it works on a minimum of programs + Wi-Fi.

Answer 2

usually such beeches come out in a line (I also have 2 videos in my laptop) are you sure that there will not be a version without a discrete one?
