Cleaner music when laptop is on battery vs plugged in

Hi,
My setup is like this : Laptop -> DAC -> Amp -> Speakers.

Recently, I tried playing music on battery (of the laptop) and noticed that the sound is noticeably cleaner and more engaging than when the laptop is plugged in the power outlet.

I don't know if anybody has experienced the same or similar.

If I use the power filter, will I have the same result?
Thank you.

Thank you everyone for the input.
@erik_squires : Which Furman equipment do you use for power filtering? I am looking for a power filter/conditioner but don’t know which one is good. Could you suggest?My budget is $300.

Thank you.

Hunt around for the Furman prices. :) You can sometimes get a BIG savings.

At the least, the two key features are SMP and LiFT. The noise filtering and surge protection is top notch.
Best,
Erik
