(Get the code!)
I have higher power consumption after suspend-resume. It raises from usual ~7 Watts to 10-11 while idle (Measured by PowerTop). I'm using TLP powersaving utility on Ubuntu 18.04 LTS and Powertop as monitoring tool. Have not noticed any CPU frequency abnormalities. Also i've tried force set frequency limit by cpupower, but no result.
I found info that dGPU may power up after suspend-resume and cause high battery drain, but my system does not contain dGPU (2200u + vega 3 iGPU)
Still on factory 1.03 BIOS.
Also have random system hangs every 5-10 hours of runtime. Two times while gaming, and ambient sounds continue playing, but image freezes and system became totally unresponsible. idle=nomwait did not help. Now I've changed amdgpu firmware files and waiting for result... If problem will repeat, I'll check RAM and update bios.
What is minimum CPU frequency for mobile Ryzens? I can't set less than 1600MHz with cpupower, but sometimes it falls to 1200 or so.
And none of methods (lscpu, cpupower frequency-info) shows turbo frequency capabilities - 2500 is maximum. But "cat /proc/cpuinfo" displays more than 3000MHz while running Mozilla Kraken benchmark.
