Lenovo Thinkpad T440 laptop Keyboard Replacement

Step 1 Remove battery and fascia slide stops

                               

• Power down the computer and remove the external battery.

• • Using a pick tool, dental pick, tweezers, small flat screwdriver, or similar probe, carefully remove the two small rectangular rubber plugs located inside the battery compartment.

  • • NOTE: Do not pierce or damage the plugs. They help provide spill resistance.

Step 2 Expose and loosen the screws

     

• Locate the two small oval depressions in the keyboard fascia, just below either Ctrl key.
• Using a flat screwdriver or narrow spudger in the depressions, slide the fascia up towards the hinges about 3mm (0.1 inches). The top edge slips beneath the bezel.
• This exposes six Phillips screw heads, located in the 3rd and 5th rows of the key area. Loosen them.

• Step 3 Free the keyboard

•       

  • Slide the keyboard up so the function-key-edge slips a small distance (3mm) beneath the keyboard bezel, freeing the arrow-key-edge.
  • Using a flathead screwdriver or spudger, lift the arrow-key-edge of the keyboard until it clears the bezel above the palm rest.
  • Slide the keyboard away from the screen, with the arrow-key-edge still above the palm bezel, until you have exposed a gap near the function-key-edge.
  • Lift the function-key edge and rotate the keyboard to expose its back. Adhesive on the ribbon cables may tug but will easily loosen with a gentle pull.

  • Step 4 Loosen the spill protection grommet

  •        

    • There is a large rubber grommet separating the keyboard from the motherboard. Its job is to help shield the motherboard in case a liquid is spilled into the keyboard.
    • The top edge of the grommet has a notch. Insert a fingertip or screwdriver and carefully pull the grommet loose. It is held in place by a weak adhesive.
    • Slide the grommet along the keyboard ribbon cable, towards the keyboard, and out of the way of the ribbon cable sockets.
    • NOTE: the thin grommet tears easily! This damage can reduce your laptop's ability to withstand a liquid spil.

    • Step 5 Remove the ribbon cables

    •      

      • There is a black plastic keeper bar holding the keyboard ribbon cable down. Slide a screwdriver just beneath the edge and carefully flip it up.
      • Slide the wide keyboard ribbon cable out of the socket.
      • There is another black plastic keeper holding the trackpoint cable in place. Slide a screwdriver just beneath the edge and flip it up.
      • Slide the narrow trackpoint ribbon cable free of the socket.
      • The keyboard is now free.
