Large spikes in CPU when laptop is plugged in

[arc_da_triumph]

Hi all,

I've been recently having a problem with my quite new (roughly 3 month old) Pavilion 14-ce3504na laptop. Whenever the laptop is plugged in, there are large spikes in the CPU, leading to large audio distortion and cut outs. This has been most apparent when attempting to do video chat (using Zoom) or when recording music (using Ableton). These issues disappear once the laptop is running on battery. I've checked for any issues with the AC adapter and the diagnostic test claims that it is fine, and I have had the same issue in multiple plug sockets. I've also uninstalled recent software, disabled my anivirus (Kaspersky) and tried to stop background programs running while the laptop is plugged in, but to no avail. If any more information is required, just let me know. Thank you in advance for your help!
