We've all heard about asus's new laptop the GX700. If you haven't here's a link http://www.pcworld.com/article/2981240/software-games/up-close-with-the-asus-rog-gx700-a-massive-watercooled-gaming-notebook.html. So this new laptop is very awesome, and has lots of cool features, but most interesting thing is its liquid cooled. But is it possible to make a laptop with the thickness of less than 1 inch internally liquid cooled with all of the liquid cooling syestems in side the laptop.

The whole point of liquid cooling is to move the heat exchange somewhere else.
By trying to do what you describe, you would have to use an extremely thin radiator in addition to thin fans to get them to fit. By doing so you would sacrifice surface area on the radiator. There wouldnt be enough heat exchange to allow for a proper internal liquid cooling setup. To say nothing of fitting in tubing, res, and pumps.

Liquid cooling *inside* the laptop is useless. The exact same heat is generated from the components, and it is still inside the case.
In addition, have you seen the inside of a laptop? There is very little free space for a radiator, pump, pipes, and fan for that sort of thing.

So i'm asking this as a theoretical question, so would it be possible in the near future, or if not what would we need to make it possible. (Be creative). Think of the most advanced liquid cooling tech. And if you think its pointless then whats a better cooling system for a laptop.

Better cooling is a good thing. But...
1. The heat exists. You must get that heat out of the box somehow.
2. Size. If you dictate a 1" thick (total) laptop, you can only use about 1/2 of that for a (small) rad. You still have to fit all the other laptop stuff inside.

Liquid cooling is not a magical panacea. Physics rules.

Solution? Don't generate so much heat.

I personally see consumer grade hardware, in this case laptop processor, to generate so little heat that they will be able to run without cooling (such as a smartphone) before we can see internal liquid cooling on a laptop.

Another thing to consider is the portability aspect. Laptops are getting thinner and lighter as time goes on, and now you are adding liquid inside them, that is going to weigh the things down.

OK, this is why more info upfront is needed.

You'd have to design the whole laptop chassis around that CPU and its cooling needs.
Again, liquid cooling is not magic. It is somewhat more efficient than an air in moving the heat away from the CPU to elsewhere. That's it. The CPU still generates the same heat.
However, as noted, you still have to remove that heat from the box.

With a desktop you have a few dozen square inches of vent holes, with air pushed out by several large fans. And through a cooler (air or liquid) of several hundred square inches of fin area.
With a laptop, you have a vent hole maybe 0.5" x 1" to remove that same heat.

And then you have the power requirements. Take a 15 kilo 'battery' (a UPS), and you can power your desktop Xeon for maybe 15 minutes. Don't think that would sell well.

Everything is a tradeoff.
