Introduction

Use this guide to replace a broken or noisy fan.

  • Shut down and close your computer. Lay it on a soft surface top-side down.

  • Remove the following ten screws:

    • Two 8 mm 5-point Pentalobe screws

    • Eight 2.5 mm 5-point Pentalobe screws

  • The special screwdriver needed to remove the 5-point Pentalobe screws can be found here.

When you say:

Remove the following ten screws:

Two 8 mm 5-point Pentalobe screws

Eight 2.5 mm 5-point Pentalobe screws

Do the 8mm & 2.5mm dimensions refer to the LENGTH of those screws, or the size of the pentalobe? That is, are there other sizes of pentalobe drivers like there are for hex, phillips and torx? When only one dimension is provided, it is usually the socket/driver size, not the screw length, maybe since the length cannot be seen when the screw is installed.

Can I suggest that you clarify your instructions so folks are confident they are only in need of _one_ pentalobe driver?

Nerdily yours,

The 8mm and 2.5mm are the length of the screws. One pentalobe P5 screwdriver suffices for all the screws (P5 is implicitly the size of the pentalobe screw heads).

  • In this step you will disconnect the battery to help avoid shorting out any components during service.

  • Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.

  • Bend the battery cable slightly away from the logic board so the connector will not accidentally bend back and make contact with its socket.

When reassembling the connector wire needs to be bent to fit.
