Subject: baseline power consumtion kernel > 5.3.10
Date: Thu, 5 Dec 2019 08:52:25 +0100 [thread overview]
Message-ID: <3ebca53c-b8fa-1e7f-6d4e-abdc93cbf2a6@web.de> (raw)
Hi,
Since Kernel 5.3.11 I got a significant increased baseline Power
consumption. I tried up to 5.4.1 on arch linux. Powertop shows an
increase from 3.6W on 5.3.10 to 5.x W on higher Kernels. My laptop fan
spins a lot more.
I read that a lot of Intel stuff has entered the Kernel in 5.3.11, could
this cause it? Will it stay like this in the next Versions? Can I maybe
switch something off etc. to get a lower baseline power?
I hope I write to the right address, otherwise sorry.
Greetings Guido
