This Macbook Air came to us completely dead from being fully submerged in a bathtub. State of the art cleaning equipment is used to remove corrosion. Our soldering technician then replaces components damaged from the water. After all damaged parts are replaced a thorough diagnostic test is ran to verify the repair is complete. We were able to repair the computer for half the cost of what Apple INC. charges. We did it twice as fast and warranty it for twice as long.
