Remove the following ten screws:

• Three 14.4 mm Phillips screws
• Three 3.5 mm Phillips screws
• Four 3.5 mm shouldered Phillips screws

Use your fingers to pry the lower case away from the body of the MacBook near the vent.

Remove the lower case.

Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

It is useful to pry upward on both short sides of the connector to "walk" it out of its socket.

Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.

Remove the following two screws:

• One 5.6 mm Tri-wing screw
• One 13 mm Tri-wing screw

Carefully peel the battery warning label off the upper case between the battery and the optical drive.

Do not remove the label from the battery.

Use the attached plastic pull tab to remove the battery from the upper case.

Use the flat end of a spudger to carefully pry the trackpad connector up from its socket on the logic board.

Open your MacBook Pro and set it on a table as shown.

While holding the edge of the trackpad closest to the logic board with one hand, remove the four 1.2 mm Phillips screws highlighted in red.

If necessary, carefully dislodge the edge of the trackpad closest to the keyboard from its recess in the upper case by pushing it away from the brackets attached to the upper case.

Carefully push the trackpad connector and cable down through the slot cut into the upper case.

It may be necessary to use a spudger to help get the trackpad connector past the edge of the logic board.

Once the cable has been completely pulled through its slot in the upper case, pull the trackpad away from the outer edge of the upper case and remove it from the machine.

When installing your new trackpad, routing the cable through the upper case and past the logic board may be difficult. It is helpful to use the tip of a spudger to guide the connector past the logic board while pushing the cable through its slot in the upper case with your other hand.

Next, reinstall the four 1.2 mm Phillips screws along the inner edge of the trackpad.

Tighten the screws all the way, then back them out about 1/4 turn.

Check the alignment of the trackpad on the keyboard side of the upper case. Once you have centered the trackpad in the upper case, tighten the four Phillips screws all the way.
