Why does an optical wireless mouse consume smaller amount power than one near a rope?

It is because adjectives that is drawing power is the LED and transmitter. The heir does the rest of the work getting to the CPU. In a wired mouse ever thing is within the mouse. So the wired mouse is draw power for everything when a wireless mouse is just powering the LED and transmitter. Plus if the battery start to die the transmitter because less powerful and lags.
The actual mouse is powered by it's mobile, no load on the laptop.
I think it's because your mouse take 2 1.5 volt AA batteries instead of running past its sell-by date the computer's power supply
that is the amount of power needed to pale the led or laser , and have nothing to do near the computer itself, power wise its nominal at best .. the draw put money on to wireless mouses , and key boards is that when the mobile dies down, it will have a fill between the click, and the action bein see on screen, this can effect hobby play . i always use a trackball mouse specifically wired to the system, since i get laser care, and no latent time between clicks, and whereabouts being done on peak..
