I noticed that my CPU works louder when I am plugging my laptop in.
I am using an HWMonitor Version 1.40.0 Driver version 148 to check my status of CPU.
I am worried that my laptop is going to damage. HWMonitor shows or my every core there is a Value around 3600 - 3900 MHz.
When I am disconnecting my power supply from the socket HWMonitor shows 690 - 980 MHz.
It's a big difference.
Is it something wrong with my laptop, power supply or maybe there is something wrong with my an electrical installation at home?
What should I check or fix?

Confused as to what your asking truly.
-are these speeds during USAGE aka LOAD, or when idle
-does it ever go down or up depending on being unplugged or plugged in
-are you running the latest BIOS update for the laptop from lenovo
Alas, some basic's
-Generally speaking, yes, your computer will have a HIGHER performance profile for all its components when it has access to the kind of power you can only get when plugged into a stable constant power source, this is both including and excluding BOOST frequency.
-Stop using HWMonitor, get HWiNFO, not that its necessarilly going to tell you different info, but it has a history (mostly with AMD but some with Intel even) of showing incorrect or easily misunderstood information so avoid it like the plague
-Check your windows/linux (whatever OS you may be using) power profile, in conjunction with the first basic statement some power profile's are set to use 100% CPU frequencey when plugged in for both MIN and MAX, where unplugged MIN is 0% (unless in use) and MAX can be anything up to 100%
Without the missing info and a few other things I cant think of at the moment, what your explaining sounds about like its operating as it is expected to.
