After a spillage on your keyboard, some keys may become unreliable. Replacing your keyboard is usually the best solution, and should be relatively inexpensive. If you want to replace your keyboard, double check that you are purchasing the correct model. You want to ensure that your new keyboard is compatible and is the correct language.

However, you may want to fix the damanged keyboard yourself. If a replacement is expensive or hard to find, or if only a few keys are affected, it may be worth trying clean the keys yourself.

The principles described below are applicable to other makes and models of laptops that having similar low profile keys. Details may vary, such as whether you should first disengage the top or the bottom of a key cap or the butterfly mechanism. Before you begin tinkering with frequently-used keys, try removing a key cap from a key you rarely use. Examine it closely to establish any differences from the ones described here.

  1. Unfortunately, pictures of the removal were not taken, but there are several YouTube videos demonstrating the process. Remove the battery, then remove two rubber bungs which are then visible in the battery compartment, their surfaces flush with the battery compartment roof.

    • Using two notches to gain purchase, 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 accessed from the underside of the laptop.

  2. Insert an opening tool beneath one of the top corners of the key you wish to remove and angle it upwads until you feel it unclip. Repeat at the other top corner.

    • 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 sort of clips at the top and botton 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 on replacing it.

  3. The butterfly mechanism has two pegs at the top and two at the bottom, which are retained under 4 metal clips. Disengage one of the top pegs by gently pushing it up and out of its clip.

    • Disengage one of the top pegs by gently pushing it up and out of its clip.

    • Repeat with the other top peg. Take care as it may take flight as the second peg is released.

  4. 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.
