Laptop performance when closed is quite variable, but depending on where you live, each 10W of idle consumption 24/7/365 could cost you somewhere around $20/yr (assumes @$0.20/kWh, YMMV). This isn’t overwhelming on it’s own, but it is “cost difference between a junked laptop and a Raspberry Pi” kinda money.
