I used to be able to just close the lid on my laptop and forget about it for days. Nowadays with the new laptop provided by my employer, if I close the lid wrong, it doesn't even go to sleep and the battery drains completely (which is... understandable, I guess, since it didn't go to sleep) but even if I do all the rituals and it goes to sleep, the battery still drains away within a few hours. I can't full charge my laptop at the end of the workday, keep my VS and stuff open, and just the laptop to sleep. I have to shut it down properly and then start everything back up again the next morning.

I noticed that my HP only really goes to sleep if I close the lid WHEN UNPLUGGED (Windows settings get ignored or whatever reason). In case other laptops work the same, glad to be of help :)

So the device is (supposedly) awake enough to connect to the Internet, check for notifications and updates, but just not quite there to notice that it has been physically unplugged.

Bravo, what an excellent design.

The same thing happens to my work Lenovo ThinkPad laptop.

Thanks for that link. My ThinkPad X1 Carbon (gen 7) BIOS supported choosing Windows 10 or Linux sleep mode - I switched to "Linux mode" and now I have S3 sleep. We'll see if that fixes the issue.

I've battled this for a long time. The prospect of having my laptop be and stay charged is exciting.

It makes sense, because one of the modes of laptop use is to attach external display, keyboard, etc, along with power (2 or even 1 USB-C cable), close the lid, and work.

It would make sense if there was stuff attached to some USB port, but it's not. I would assume the laptop should know this, but again, it's not.

My employer disabled sleep entirely for some reason (not even available via the power menu), which means that if I forget to hibernate it before I throw it in my bag it’s concerningly hot by the time I get home.

What’s double weird is that, if I close it without hibernating it, not only does it not lock the laptop but it seems to prevent the “lock after x minutes inactivity” setting kicking in. Which seems like a huge security problem.

That happened to Ubuntu on my personal laptops, and occasionally I'd notice the mouse cursor was on a different position than when I closed the lid - I think the screen was somehow triggering the touchpad and that kept it awake/unlocked.
