WARNING
!! These instructions are presented in a general way. Sony VAIO of Europe hereby informs you that the self-replacement of keyboards should be performed with care. If any damage is caused to components of your VAIO while replacing the keyboard, their repair or replacement will be considered as out of warranty and therefore chargeable. !!


  1. Shut down the computer and disconnect all peripheral devices.
  2. Unplug the computer from the AC-Adapter and remove the battery pack.
  3. Touch a grounded metal object to discharge static electricity, for example a radiator or a tap.
  4. Place the unit upside down on a table. Use a piece of cloth to protect it against scratches.

  5. Remove 7 screws (marked red in Figure 1).

    Figure 1 - Removing 7 screws from the bottom.


  6. After the screws have been removed, the optical drive can be pulled out of the unit as shown in Figure 2.

    Figure 2 - Remove the optical drive


  7. The keyboard is fixed with hooks on three sides and with dents that slide into the touchpad side of the keyboard (see Figure 3).

  8. Inside the optical drive bay, there is a round opening towards the keyboard. This opening is used to release the hooks that hold the keyboards top right corner fixed to the palm rest (see Figure 4).

  9. Figure 4 - Location of the access opening in the optical drive bay


  10. Place the VAIO on a table opened in working position, but with the open optical drive bay at the edge of the table towards youself. Use the opening illustrated in Figure 4 above to push the keyboard away from the palm rest. This will release all hooks on the keyboard's right side and a third of the hooks on the keyboard's top edge (see Figure 5).
    Note: If you cannot reach the opening with your fingers or have difficulty releasing the keyboard, use an improvised tool to do so. A thin, rigid and non-metallic object is suitable for this, e.g. a cheap plastic pen.

  11. Once the top right corner of the keyboard is released, push the keyboard's center up and towards the palmrest to release the remaining hooks on the keyboard's top edge, followed by the hooks on the left side.

  12. Once all the hooks are released, move the keyboard slightly towards the display to release the dents, then place the keyboard upside down on the touchpad area as shown in Figure 7.

  13. If any tape secures the keyboard flat plastic connector to the connector, carefully peel it off.

  14. Caution:
    • If the keyboard connector is broken, the mainboard needs to be replaced. The cost of replacing the mainboard may exceed the value of a used VAIO.
    The mainboard’s keyboard connector is composed out of two parts: a fixed part (beige) and a bracket (dark brown), which holds the keyboard's flat cable in place. Carefully unlock the bracket from the connector by pushing gently at it's corners as shown in Figure 8.


    Figure 8 - Detaching the keyboard's flat cable


    The keyboard's flat cable should then be free and will slip out of the mainboard's connector without effort.

  15. To install the new keyboard, reverse the procedure while taking note of the following:
    • To avoid unnecessary work, test if the keyboard's flat cable is well connected before continuing with the reassembly. To do so, connect the AC-Adapter to the VAIO, press first the power button and then F2 as soon as the VAIO logo is displayed to enter the BIOS. If that works, switch the VAIO off again, detach the AC-Adapter and proceed with the reassembly.
