What am I missing here?

[Basil Chupin]

I spent most of today downloading and installing Beta #1 of Kubuntu - a 
few hassles but, hey, fine, it is a beta after all so no real problemo.

But at the beginning of the installation procedure I noticed that I got 
the message:

Preparing to install Kubuntu.

For best results, please ensure that this computer:

is plugged in to a power source


(This was one of 3 "hints".)


Am I missing something here about this message?

If I don't have the computer plugged in to a power source I will get a 
rotten result, but nevertheless the system will still work?

But if the computer is not plugged in to a power source, and that power 
source is also not switched on, then I wouldn't be reading this helpful 
hint, right?

Or is there another hidden meaning to this message which I have yet to 
work out - I mean, I have only ever worked with desktops so is there 
something about laptops to which message applies?

Thanks for any clarification.
