When I open a new notebook on Goole Colab I see a "POWER LEVEL" indicator with a battery symbol at the top. I can click it and choose three different power levels: low, medium and high.
I don't remember ever seeing this before on Google Colab. I believe this is a new undocumented feature.
Does anybody know what is the effect of changing power levels?
Power level is an April fools joke feature that adds sparks and combos to cell editing --
