Just because the laptop is powered down does not mean that no circuits are getting power. Wake on LAN/WLAN is a thing, and most devices without a physical power switch, (a power bitton is not a switch), mean that there is a miniature power draw listening for that signal. The manufacturer might have other bits that are still active as well, you can’t be sure. If your ultra paranoid about state level actors it might be a good idea. If you’re just worried about somebody swiping your credit card number or something, probably overkill.

It’s WoL, not WLAN. WLAN is Wireless Local Area Network.
I believe the previous post was talking about Wake on LAN (WoL) and Wake on WLAN (WoWLAN) which are separate things.
