The Linux distros I have used do not seem to turn on full blast anti-virus scanning and search indexing when your laptop goes idle. Not sure about ChromeOS but this is something that causes terrible fan noise on Windows when you expect the machine to be silent. I never could get it under control way back when. Lenovo may not like the negative reviews about fan noise and battery life when it’s generally a software problem.
