This is my first installation of Arch, so I may have forgotten something.
After booting it, the laptop quickly starts to became hot. I've been reading documentation on Arch wiki, but didn't found nothing about it.
My first guess is that CPU is running at max speed, but the
cpupower says it isn't:
analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 hardware limits: 800 MHz - 1.90 GHz available frequency steps: 1.90 GHz, 1.80 GHz, 1.60 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz, 800 MHz available cpufreq governors: ondemand, performance current policy: frequency should be within 800 MHz and 1.90 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 800 MHz (asserted by call to hardware). boost state support: Supported: yes
grep "cpu MHz" /proc/cpuinfo says I'm running both CPUs at 800MHz.
cpu MHz : 800.000 cpu MHz : 800.000
On Windows, it works perfectly, so it's not a hardware problem.
My CPU is an AMD A4-3300M APU with Radeon(tm) HD Graphics.
