Einleitung

Use this guide to replace just the LCD rather than the entire display assembly.

  1. IKWvCoyRw5ysaanv

    • Use a coin to turn the battery locking screw 90 degrees clockwise.

    • Lift the battery out of the computer.

  2. ZQcBbKlGtFilSqNu

    • The following procedure allows the changing of the rear display bezel without removing the display assembly from the computer. Do not attempt to rotate the display back farther than the hinges allow or your computer may be damaged.

    • Open the computer with the display facing you and rotate the display back as far as possible.

    • Remove the T6 Torx screw from the bottom left corner of the display assembly. The computer casing will not allow the screwdriver to be inserted directly into the screw, so be careful not to strip the screw.

  3. rAlqemRJehxBRGFY

    • Remove the T6 Torx screw from the bottom right corner of the display assembly.

    • To avoid cross-threading these screws during reinstallation, use a pair of tweezers to start each screw in its hole before using your Torx screwdriver to tighten them.

    • The next few steps require the use of plastic opening tools and spudgers that will probably be destroyed in the process. Have a few spares of each tool handy.

    • Insert a plastic opening tool between the left edge of the front display bezel and the plastic strip attached to the rear bezel, with the edge of the tool angled toward the LCD.

    • Rotate the tool away from the LCD to pop the rear bezel off the tabs on the front display bezel.

    • Work along the left edge of the display until the rear bezel is evenly separated from the front bezel.

    • Freeing these tabs may require some force. Be sure to support the display assembly with your other hand to avoid putting too much strain on the hinges.

    • Insert a spudger just to the left of the hinge opening on the top edge of the display between the front display bezel and the plastic strip attached to the rear bezel.

    • Pry the rear bezel away from the front bezel along the top left half of the display.

    • If the flat end of your spudger is flexing too much, trim about .125" of the end to increase its stiffness.

    • Pry the rear bezel away from the front bezel along the top right half of the display.

    • To release the clips in the far left and right corners of the display, it may be necessary to run a spudger parallel to the face of the display along the top edge of the front display bezel and force it into the corners to pop the rear bezel off.

    • The inverter is an extremely thin circuit board that is very delicate and easily cracked. Take care when handling.

    • Using the tip of a spudger, raise the inverter out from the clutch cover.

    • Lift the inverter enough to reveal both cable connectors.

    • If necessary, remove the piece of tape covering the display data cable connector.

    • Pull the display data cable connector away from its socket to disconnect it from the LCD.

    • Lift the LCD off the front bezel enough to insert the flat end of a spudger between the metal LCD frame and the front display bezel.

    • Trying to insert your spudger between the LCD glass and the inner metal LCD frame will surely damage your LCD.

    • Run your spudger along the lower edge of the front display bezel to separate the adhesive from the LCD frame.

  23. MGXVtvuCGEHL2pS6

    • Remove the small magnet near the top left corner of the display, making sure to mark its orientation before removal.

  24. gSwlA2KZIXCZhPXB

    • Pull the LCD toward the top edge of the front display bezel, minding any cables that may get caught.
