Re: yet more numpties
Inductive heating needs a high amperage before you get heat, I don't think any ordinary laptop gets close to what is required to have that as a risk.
As for rolled up cables, it again depends on use. I've seen reels stating both a rolled up and unrolled wattage, which strikes as the most sensible approach. Personally, I prefer to use a fuse that limits current to the rolled up rating - prevents mistakes (that won't work, of course, if you use stuff that needs power like electric heaters).
