[SOLVED] Intel_pstate driver doesn't load on Sandy Bridge intel i3

Laptop: HP 4530s
Processor Sandy Bridge (Core i3) i3-2310M CPU @ 2.10GHz
Kernel: 5.9.14

I was making some testing with undervolting using the intel_cpufreq driver. By chance I realized that the proccessor supossed to use the intel_pstate, but it uses intel_cpufreq driver instead!!
Kernel should have load that driver automatically but it doesnt. I tried to "force" enable it with intel_pstate=enable kernel parameter via grub, but didn't work either.

Any ideas??

Adding the intel_pstate=active parameter did the trick.
