Isn't that the "modern standby" thing? Mine (p14sg6 intel) "works well" in that it suspends, wakes, etc (under linux, don't use windows enough on it to have formed an opinion).

But it doesn't support S3 (suspend to ram), only s0ix:

    $ cat /sys/power/mem_sleep
    [s2idle]

In both cases, the peripherals are put to sleep, and the RAM goes into self-refresh mode. The main difference is that if there are any bugs, they can be fixed in the OS rather than the BIOS.

I haven't tried this much on this Lenovo laptop, but on my HP ones, both Intel and AMD, the main difference I notice under Windows is that the laptop stays warm to the touch in this mode, whereas in S3 on older machines it used to go cold. Additionally, with both Linux and Windows, the battery drains much more quickly compared to the old S3 mode (even though on Linux it gets cold to the touch).

The HP Intel is the one I use Windows most often on (since sleep is basically borked on Windows on the AMD one), and on that machine, I actually hear the fans running while in standby (it wasn't actually fully on, judging by the LED pulsating instead of being continuously on). Which is absurd, since the fans are hardly ever audible under Linux in normal office use.
