Laptop with inert gas for lightness

Question

laptops

I have a powerful laptop from the Desktop Replacement category, and this miracle weighs about 3 kg.
I would like to reduce the weight, and so I thought about a container of gas, which is lighter than the air inside the laptop case.
I'm not sure that such a wild idea came to someone's mind, but it's interesting what anyone thinks about this, and what they can advise)

Answer 1

Some nonsense, then it’s better to have a vacuum; in general, its weight is close to zero.
Were you at school? In chemistry they show gases and in physics.
Have you seen the lift of a helium balloon?
To raise the laptop they need a volume of liters per thousand probably.
