Y580 does it have switchable graphics or not? [ Edited ]

[velenoso666]

On this page Y580 in the full specs tab it shows 

It doesn't say anything about Intel® HD Graphics, am I right in believing it doesn't have switchable graphics? Because I would be interested in buying this laptop if it doesn't have switchable graphics.

Im also interested in this feature.

I think all core i processors have the integrated cards

I don't believe so (but I could be wrong) just because in the specs for the Y570 on the same site it shows 

which appear not to be the same.

it should be switchable from what i am reading. But i could be wrong.

Well that would be a really stipid decission. I enjoy the switchable graphics. I don't trust this website because they say that the optimal processor for the Y570 is Core i7-2920XM and I have never ever seen such y570 (believe me I have checked almost every website that had info about the laptop before I purchased it) and they say that the GT 555 is available with 1 GB GDDR 5,mine has 2 GB and so on. So I think they made a mistake when they wrote the review.

looking at the battery life (5 hours), it probably has switchable graphics.

@kostadinbal

lenovo Y570 has 1 GB GDDR5, not 2 GB

I can show you my GPU-Z information if you wish

Could it be from different model?

Because mine shows 1 GB both on GPU-Z and nVidia System Information
