Unless you're planning on leaving the laptop in Norway (or technically: have it stay in Norway for more than 90 (iirc) days), that is absolute bollocs. The laptop is just a personal possession with effectively negligible value, and you won't need to declare it.
If you are a Norwegian resident returning to Norway after having bought the laptop overseas, this applies.
That said, you'd probably be the first to actually claim it if you did I know a lot of Norwegians that buy laptops and other stuff overseas and don't pay the customs when bringing it back. There's actually a whole market here around students travelling to the US to buy apple laptops and then selling them via the internet when they get back. If they sell one, they've usually recouped their flight, so by buying/selling 2 or more it becomes a bit of a side income.
Clearly it's considered smuggling if you don't claim it when returning and are living here, so I'm not recommending you do this if you live here permanently.
