Luckily not having this problem, but Modern Standby is such a fucking shit show.<p>I always quietly snickered at the people posting about hot laptops in their bags given that ACPI S3 has been working well for me these past years (finally!).<p>Turns out my current machine has modern standby (S0 Low Power Idle Network Connected) and doesn't let me disable it! Apparently not even the network connection part. There's a group policy setting, but it says it only applies to WiFi and that "may change in the future" (probably not for the better).<p>So now I too have a laptop that spins up its fan whenever it likes to and doesn't reliably sleep (sometimes it manages to, sometimes not). Back to hibernate? What the fuck is going on?
