I have a lenovo laptop (Lenovo IdeaPad S340-14IIL) with an Intel i7-1065G7 CPU, for the last few days it has been using incorrect max frequency settings.
It should be capable of turboing up to 3.9ghz but its maxing out at 1.6ghz
I did a reset by holding down the power button, and that upped reported hardware limit back to 3.9ghz, but cpupower is still reporting that ‘current policy’ allows frequency to be within 400mhz and 1.3ghz.
I am running auto-cpufreq but that should be limiting the max freq to 3ghz via the config file. Its reporting CPU max frequency as 1300mhz via --stats
