My CPU is only running at a speed of 0.40 GHz while plugged in.

I just bought a new laptop and my CPU Ryzen 5 3550h is only running at a speed of 0.40 GHz while I have plugged in the charger and when I unplug the chord the speed goes back to 1.7 GHz. I don't know what might be happening when I plug in the charger.

Thanks in advance for the help.

@GreatAmrit , welcome to the Community.

I have read that this may be caused by the rapid charge function if your computer has it.  I suggest you check to see if your laptop has this feature.  If so, you can turn it off to see if that solves the problem.

Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.

You are welcome, @GreatAmrit!  Thank you for the additional information.

If you do have this feature you would have to turn it off in the BIOS/UEFI.  Begin tapping F11 once per second when the computer begins to boot.  This will take you to the BIOS Setup Menu.  You can choose where to go from there.
