Public bug reported:
After boot the idle power consumption is around 2.3 W but after suspend it is
4.7 W.
The measurement is 5-10 min after boot/resume - looking at "top" to see system
was idle.
This is consistent - I have tried more that 10 times.
BIOS is updated to latest version.
I have checked power consumption with external meter - and confirmed that it is
higher.
I have attached output of:
sudo powertop -t 60 -r --html=before.html (and after)
I have noticed that Package C-state 6 is reached before suspend but not
after.
I expect that idle power consumption after suspend should be the same as
before.
