No, probably not. Because a hyperintelligence would not be constrained by your closet or forgetfulness to plug in the laptop. Especially with a network connection, it should have no problem breaking out.

You're just assuming that. Why would it have no problem? Because of reasons we can't understand? In that case, "hyperintelligence" is equivalent to saying "omnipotence" in this regard, and as such we can easily dismiss it as an option.
As an example, it could manipulate frequencies of its hardware to broadcast signals (like using monitors to broadcast on FM) and entice people to connect it.
With a network connection, this is straightforward. It could hack servers for computing resources. It could do work (say, as a camgirl) for more money and hire meatspace resources if needed.
A nice thought experiment is assume an intelligence has a 128Kbps Internet connection - what real limitations does that impose?
