Low CPU Frequency

[sauka]

I have Dell Latitude 5500, Win11, CPU i7-8665U. From time to time CPU is going to very low frequency (0.6-0.7GHz, when nominal is 1.91GHz. And it happens randomly, meaning if the load is high (being plugged in). As a consequence, everything is lagging heavily. I've mentioned, that if I set power saving mode on and then off quickly, it help get back to high frequency. 

Is it a cpu issue or am I missing smth in setup?

Thanks
