Which consumes least power from the laptop battery out of the following - a corded USB mouse or a cordless mouse with USB transceiver or bluetooth wireless mouse?
I have a laptop running Windows 7 64-bit and am looking to use a solution that'll use the least amount of energy from my laptop's battery. yes, I know the built-in touchpad would use the least energy but I'd like to use an external device - more comfort.
Either via practical experience or via tests carried out, could someone please help to narrow down the type of mouse that'd serve my purpose? Not looking for a fancy mouse - 2 button + wheel is enough.
