i don't know about other people's experience - but my framework with intel cpu is always running that fan relatively maxed out even when it's not doing anything. And it has massive issues staying asleep which is some sort of driver issue with Windows. But I can be an airport and all of a sudden my backpack feels like it's about to combust and i can hear my laptop fan rippin', even though it should be asleep.

That is by design, it's a feature from Intel and Microsoft called "modern standby." It basically means your laptop cannot actually sleep anymore. Instead, it enters a slightly-lower-power mode so that it can download emails in the background, run Windows updates in the middle of the night, and generally pretend to be a phone even though no one wants that and the hardware/os was not really designed for it.

Modern Standby requires that deepest sleep states take less power than S3 standby, the issue is mainly drivers and applications either waking the system or not putting peripherals into deep enough sleep (or shutting them down entirely if possible)

Some new laptops cannot actually fully suspend to ram. It sounds crazy but I had this issue even after installing Linux on a laptop. It’s a hardware limitation. You can thank Microsoft for trying to make sure they can sneak in OS updates when you think your laptop is asleep.

It's not sneaking in OS updates, it's faster wake-up mainly.

Combined with properly prepared HW taking less power in modern standby than in S3, but it requires hardware/firmware/driver/userland confluence to work well

By the way, how do people carry those laptops on airplanes if regulations mandate that every radio equipment must be off?

[wkat4242]

They don't. Only cellular connectivity. Most airlines even offer WiFi now

[jazzyjackson]

Mandate is a strong word.

[p_l]

Airplane mode is still a thing.

I'm not sure I had the same issue, it is a different laptop, but it would not go to sleep. The current solution is to make it hybernate instead of sleep.
