Not just laptops but affects computers too. I have a brand-new Mini PC with Windows 11 and when you turn it "off" it continues to pull 6-10 watts. Not a lot but still over a year if you were to only used it minimally that's 52-83kwh or around $25-45/year at PG&E rates. Vendors are removing support for classic standby/hibernate so the only way to go to <1 watt is to pull the plug. It shouldn't be this way.
