    • Unfortunately, pictures of the removal were not taken but there are several YouTube videos demonstrating the process.

    • First, remove the battery and then remove two rubber bungs which are then visible in the battery compartment. Their surfaces are flush with the battery compartment roof.

    • Using two notches to gain access, slide the inter-key sheet upwards, revealing 6 small screws.

    • Remove these screws.

    • Now carefully lift the top of the keyboard and angle it towards you, revealing its two ribbon cables.

    • Gently lift the locking tabs on the ribbon cables and withdraw the ribbons. You can now remove the keyboard.

    • On different laptops, there are several methods of removing the keyboard. In some, you only need to release tabs along the top. Others are retained by screws under a bezel between the keyboard and the screen or they are accessed from the underside of the laptop.

    • Insert an opening tool beneath one of the top corners of the key you wish to remove and angle it upwards until you feel it unclip.

    • Repeat at the other top corner.

    • You should now be able to lift the key cap off, moving it slightly in the direction of its lower edge.

    • On the underside of the key cap, notice the different sorts of clips at the top and bottom of the key. The top ones are designed to push on or pull off but the bottom ones push on only. For this reason, you must remove the key cap by first lifting the top corners (not the bottom) and re-engage the top clips first when you replace them.

    • Repeat with the other top peg.

    • Take precautions as it may take flight as the second peg is released.

    • In the key cap well, you will see the silicone rubber snap-action key switch actuator. When depressed, this brings two contacts beneath it together. This is glued in place and you will probably tear it if you try to remove it.

    • First, blow out the dust and loose dirt. Then, clean out the well with isopropyl alcohol and an old toothbrush. Pay particular attention to the metallic area around the silicone. Allow it to dry.

    • To replace the butterfly mechanism, first, verify that you are holding it the right way round and the right way up.

    • Position the bottom pegs in their clips and then, holding it in position with a finger, press each of the top two pegs into their clips.

    • To replace the key cap, carefully place it accurately in position and first press the top corners in order to engage the top clips. Then press the bottom corners to engage the bottom clips.

    • Check that the key cap is level, all four clips engaged and that it moves freely up and down.
