Remove speaker from slot on back panel by prying out of the rubber/plastic case with the plastic opening tool. If this does not work the metal spudger is okay for this step.

Remove the existing speaker from it's connection to the motherboard by pinching both sides of the connector.

Pull back away (in the opposite direction) from the connector.

When reassembling push back into connector. Do not need to pinch anything. The "click" sound insures solid connection.
