on bug 108058
from Tolga Cakir
I might have the same issue - I posted it under bug 98386. Happens on a Dell M3800, Intel Core i7-4702HQ, Nvidia Quadro K1100M, Arch Linux w/ kernel 4.19.2. Same as you, after fresh boot I get around ~7W in idle and after S3 resume I get 15W and more, no matter how long I wait. Contrary to your observations, bbswitch works for me; nouveau doesn't. I have found out, that echoing lowest pstate (/sys/kernel/debug/dri/*/pstate) after S3 resume solves this issue. Power consumption drops back to 7-8W in idle. I will post full dmidecode and dmesg in a couple of hours.
