Re: >10W idle power usage on framework laptop 12th gen 13inch



Linux has drivers for devices shutdown when not used and idle power
states, pretty much like Windows has. Android, who is Linux derived,
took this concept to a much higher level.
Think of a wireless card and you can see on man ath(4): " The driver
does not fully enable power-save operation of the chip; consequently
power use is suboptimal." This is one of the simplest example.

I configured a very stripped down linux kernel and it idles at about the same watt usage as OpenBSD.

I guess it's a matter of figuring out which drivers or kernel features are saving so much power.

I flashed my bios to the newest one they provide and Linux uses even less power; I did not see much difference on OpenBSD.
