If you look for a “watt meter plug”, you’ll pribably understand what it is at a glance. It’s a device you plug into your wall outlet (or surge protector or whatever). It has a power outlet on it, which you plug your device into, and a screen that shows watts drawn and watt-hours over time. Super simple. I think “Kill A Watt” is the most well known brand.
I suspect that there is “palm check” turned on for your touchpad. This is designed to keep you from accidentally moving/clicking the touchpad by brushing it with your palm while you are typing.
Look for a “palm check”, “palm rejection”, or “disable touchpad when typing” setting in your touchpad utility. As far as I know, these are all roughly the same thing.
