At $69, Apple's Bluetooth Mighty Mouse is not exactly the cheapest electronic rodent on the block. But if you're willing to open it up to make it more battery-efficient, this reduced power hack may be for you.

Ram, the mouse hacker, was playing with his Mighty Mouse when he noticed its LED came on and off on the bottom of the mouse. When the mouse was not in sync with a Mac, this LED would blink. Once sync'ed, the LED would go out if the mouse is in use. When the mouse is stationary, the LED would go on an stay on. He measured the power usage of the mouse and was proven right: The mouse seems to use less power when in use and the LED is off than when it's resting and the LED is on. Thinking like a hacker, RAM proceeded to devise a way to double battery life "depending on your mouse usage behavior."

He dismantled his Mighty Mouse to remove the pesky power-draining LED. "In the end the hack still saves some power but no where as near as what I was expecting," he says. It's your mouse (make sure it's yours) and if you want to wreck it turn it into an energy miser, well, consider this your warning. Proceed at your own risk! Click here for the how-to.
