When it comes to wireless peripherals, every little bit of battery life counts, so a modder named Ram Sripracha was a little concerned when he noticed that the LED on his new Bluetooth Mighty Mouse
stayed lit even when the device was on standby. Since he was already handy with the tools of the trade, Ram cracked open the mouse to test its power consumption with his trusty multimeter, and discovered that it was actually sucking more juice when sitting idle (about .0450 amps) than when in use (around .0285 amps). With the rodent already splayed out on his desk, Ram decided to remove the LED himself and retest the current draw; sure enough, it only used .0017 amps without the light on, or about 3.9% of its draw in an unaltered state. Luckily for you, he also posted an illustrated, step-by-step guide on how to perform this surgery yourself, but be warned that Apple's crack design team made sure that disassembly is more difficult than just unfastening a couple of screws. Also bear in mind that this is just one person's experience, so you'll probably want to make sure that your Mighty Mouse is putting on this perpetual light show as well before you break out the silicone glue and soldering iron.
