[SOLVED] CPU clock speed is high when plugged in (charging) ?

[Recker Code-1]

I have a hp pavilion notebook laptop it comes with i5 8th gen processor 8300H with 2.30 ghz base clock speed recently i was looking into my task manager of my laptop and i notice a weird clock speed going up high up to 4ghz and the cpu utilization is low like 2% (while it is connected for charging or AC power) but when it not connected to charging or (not connected to AC power) the clock speed comes down to normal according to it's utilization. I have restore the power management of my laptop.

it could be a startup program over ruling the power schemes when its running off mains instead of battery

Try a clean boot and see if it changes anything - make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows

if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
