I was on the octopus energy website and a little box popped up saying that my laptop was over 80% full and uk emissions were high so I should unplug.
How would the website know this?

What options have you got for blocking pop ups and ads?
As I support this site I've disabled my usual ad-block software for car4play.com.
After a brief exchange with Zero about hobby radio I was fed a whole series of ads for a Ham Radio Store in the West Midlands. They're reputable and I've bought air band aerials from them in the past but it's pretty clear how ads eat cookies.

It wasn't really an advert, I unplugged my laptop and the box disappeared I then plugged it back in and the box popped back up. Just wondering how it would know what my laptop charging state is?
No pop up or ad blockers.

Not being really into computers I'm not sure I followed any of that, websites can access your battery levels through some of script thing?

Ignore the rest of the page Kevin posted, just read the first bit:
"The BatteryManager interface provides ways to get information about the system's battery charge level.
"We can use the Battery Manager to detect
- charging state
- Battery percentage
- Time needed to charge 100%
- The remaining time until the battery is completely discharged."
So yes, some sort of script thing can read the above (and I don't think you can sensibly prevent it but I may be wrong. I think you can stop scripts running but that would not be desirable AFAIK)

Thanks, never seen that before.

>> Thanks, never seen that before.
It's part of how you are identified and tracked. The combination of features they can track/detect allow them to either uniquely or close to uniquely identify you.
Detecting your operating system, browser version, installed plug-ins & versions. screen resolution, fonts, time zone, etc. etc. etc. gives them a unique combination identifying you.
So you may log not one site as Joe, into anther site as Bloggs, into a 3rd as Anon and anonymously via a vpn on a fourth, and they can detect that they are all from the same computer.
So if they buy loads of records from loads of different sites, they can build up a fairly scary record of everything you do, without you actually telling them anything.
Don't forget, even a VPN only stops your ISP tracking you (and potentially sharing that with the State), the website you're going to still knows all it wishes to know about you.

What happens in a typical family household where several people share a computer? Presumably they would be classified as one person?

Entirely depends if you all use the same logon on the pc. Few families do, each person having a sign on on the PC, and in this case each user browser becomes different - a separate identifiable instance in pc code.

Clearly
developer.mozilla.org/en-US/docs/Web/API/BatteryManager/onchargingchange
But only on some browsers, and is a deprecated feature
