The Microsoft Natural Ergonomic Keyboard 4000 is a computer keyboard with a slightly curved design that fits with your natural wrist and arm alignment. The keyboard's host of other features, such as customisable hot keys and palm rest, makes it a high-tech computer accessory, which is why you may be reluctant to open it up if there's a problem. You can disassemble the 4000 on your own and without the risk of any damage to the keyboard.
Unplug the Ergonomic Keyboard 4000 from your computer and place it face down on a sturdy workspace like a table or counter.
Use your Phillips screwdriver to remove all 21 screws on the underside of the keyboard. Set the screws aside.
Turn the computer right side up and slide the wrist pad off the bottom of the keyboard. Insert the tip of your flathead screwdriver under the front of the space bar and gently pop the space bar up to remove it from the keyboard. Set the keyboard aside. Two small screws will now be visible where the space bar used to sit.
Use your Phillips screwdriver to remove the space bar and set the screws aside. Gently pry the top cover of the keyboard up to remove it from the bottom half. Set the top cover aside.
Use your Phillips screwdriver to remove four more screws under where the "Back" and "Forward" buttons sit and set them aside. Use your fingers to remove the silicon pads that sit on the bottom half of the keyboard and set those aside. Your Ergonomic Keyboard 4000 is now disassembled.
Disassembling your Ergonomic will void any warranty you may have on the keyboard.
