CPU Frequency on battery power very low on a Intel 12gen #660
Comments
After a day of attempts, switched the driver with intel_pstate=disable , disabled C0 CPU halts with idle=poll in grub, tweaked /dev/cpu_dma_latency and etc brought no improvement. |
Seems the laptop is restricted by the manufacturer to no more than 15Watt while on battery. Played with |
Closing the issue due to inactivity as it seems unrelated to auto-cpufreq. |
Replaced the Intel Pstate driver, as can be seen below.
I always get :
CPU max frequency: 2501 MHz
CPU min frequency: 400 MHz
regardless of settings in /etc/auto-cpufreq.conf
While on AC power, the system works as expected.
On battery power the CPU never gets above 2500Mhz, even though the temp is below 40 degrees.
On AC they reach 4400Mhz.
