If you look at p. 40 of the Manual that model series could have either a dedicated video option or an integrated:

The heatsinks are different:

Looks like you have the heatsink for dedicated video and your motherboard is actually integrated video. You can check the installed hardware with an app like Speccy or it is just apparent there is no chip where the dedicated video would be. I can't see where this would cause any problems.
