This micro chip is easy to install. It plugs into the socket on your circuit board and upgrades your charger to the latest Software Version 2.0. Remove the four screws which are holding the charger together. Flip the face plate over. Use needle nose pliers to carefully remove (wiggle upwards) the old chip from its socket and carefully press in the new chip. The small notch on the chip faces the middle of the charger, not the edge of the charger. If it goes in backwards no harm will be done, but you will see black squares on the display. You may use a Popsicle stick to guide in the feet and press gently.
