What you need

Step 1

              Keyboard, Speakers, and Speaker Panel

With the computer facing you, locate the screw on the back left-hand side of the computer (purple marker). This screw keeps the speaker panel and keyboard in place. Use a small Phillips screwdriver to remove the screw. After removing, place the screw in a secure location – it will need to be replaced later.

Step 2

Open laptop facing towards user
BEFORE REMOVING SPEAKER PANEL: Note that a ribbon cable connecting the panel to the computer’s motherboard is present (red marker). Removing the speaker panel too forcefully could damage this cable and/or its connection, possibly causing severe, irreversible damage to the computer.
Now that the screw has been removed from the side of the computer, the purple speaker panel can be removed. Carefully lift the left side of the panel, unhook the right side, and remove the panel a couple inches from the computer, taking care not to pull beyond the length of the ribbon cable that secures it to the motherboard (red marker).
To remove the ribbon cable (red marker), grip the cable near it’s connection point and gently pull. The speaker board should now be fully separate from the computer.
NOTE: If you do not wish to replace the keyboard, proceed to “Step 4”.

Step 3

BEFORE REMOVING THE KEYBOARD: It is crucial that the user ground his/herself to avoid damaging sensitive hardware via static electricity. By doing this, user will not have a shock from the product This can be accomplished by touching a metal lamp that is plugged in, or the back of a desktop computer that is plugged into a wall outlet.
ALSO NOTE: A ribbon cable connecting the keyboard to the computer’s motherboard is present (purple marker). Removing the keyboard too forcefully could damage this cable and/or its connection, possibly causing severe, irreversible damage to the computer.
With the speaker panel absent, the keyboard can be easily removed. lift the keyboard a few inches from the computer, taking care not to pull beyond the length of the ribbon cable that secures it to the motherboard (purple marker).
Identify the ribbon cable connecting the keyboard to the computer’s motherboard (purple marker) and remove it by gently pulling near its point of connection.
Once the cable is free from the motherboard, the keyboard is fully separated from the computer.
NOTE: If you do not wish to replace the speakers, proceed to “Step 7”.

Step 4

Identify the speakers on the underside of the speaker panel. Unplug the black and red wires connecting the speakers—on both ends of the panel—to the circuit board on the center of the panel by carefully pulling at the wires close to their connection (red markers) with the circuit board.
Using a Phillips screwdriver, remove the four screws—two screws per speaker— and the metal brackets holding the speakers in place. Place the screws and brackets in a secure place – they will be replaced later.
Remove the adhesive tape securing the speaker wires to the panel.

Remove the adhesive tape securing the speaker wires to the panel.

Step 5

A sticky adhesive holds the speakers in place in addition to the screws. The speakers will likely be reluctant to detach from the panel due to this cement.
To overcome the adhesive and remove the speakers, place the screw driver in the hole in the speaker mesh and pry out, using the raised metal lip in the center of the speaker for leverage.
A good amount of force may be necessary to completely overcome the adhesive. NOTE: The tweezers or needle nose pliers may be used in place of the screw driver.
