Product: Pavilion 15-cs3019nr
Operating System: Microsoft Windows 10 (64-bit)

Hello, I get CPU frequency dips (see the picture from resource monitor) when my laptop is plugged in, but not when running on battery.   This is associated with decreased performance and often the fan running loud.   I worked with HP support, who sent me a new AC adapter which didn't solve the problem.  I took the laptop to microcenter who could not find a hardware problem, including testing the ac adapter, and they did a registry cleaning, but still have the problem.   I don't do very intensive stuff...no gaming.  Typically have chrome and word or PowerPoint going and on zoom or Microsoft teams meetings.  When the CPU frequency dips in a zoom or Microsoft teams meeting, the audio becomes garbled and robotic, but the video seems to be ok.  This is very frustrating because I upgraded to this computer specifically because I needed something reliable for working from home...but this has been less reliable than an old i3 doing the exact same tasks.    No one seems to be able to explain why I might have a problem only when plugged in, but not when running on battery.  Any thoughts?

 

Thanks!!!
