  • Remove the eight 4 mm Phillips screws securing the lower case to the MacBook.

According to this page http://support.apple.com/kb/HT1651?viewl..., the 8 screws are not identical.

Can anybody tell me where each kind of screw is supposed to go?

They are all 100% Identical. You were probably looking at a different model, or Apple has entered the wrong information... Hey, It happens...

The screws on the Late 2009 are identical. The blue lock compound might make tightening some require a little more effort.

The A1342 will take up to 16 GB of RAM, however, there are only two RAM slots, so use two 8-GB RAM modules. Other World Computing (OWC) is a great reference source for info on exactly which RAM to use with which model; prices are usually much better on EBay though. Add an SSD from OWC and your machine will really scream!

I hope that helps!

The lower case is constructed of rubber-coated aluminum. Do not excessively bend the aluminum during removal, as any permanent deformation will cause tolerance issues after reassembly. Slightly lift the lower case near the vent opening. Continue running your fingers between the lower and upper cases until the upper case pops off its retaining clips.

  • The location of these three clips is shown in the third picture.

Do the retaining clips have to be re-engaged when replacing the lower case?

Answering my own question, the clips re-engage when the lower case is correctly positioned. You can help them by gently pressing the lower case with your thumbs midway along the two short sides. When everything is correctly aligned the eight screw holes line up.

For precautionary purposes, we advise that you disconnect the battery connector from the logic board to avoid any electrical discharge. This step is optional and is not required.

  • Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.

  • It may be easier to use your fingernails to lift up on both sides of the connector.

you do not need to remove the battery when replacing the hard drive or ram

beware not to lift the connector to close of the angle, as the picture suggest it. It might broke the angle. Attack by the middle.

Not necessary?

Be careful of the corner of the battery cable connector when trying to pry it off with the spudge. I knocked the corner of mine. No operational impact but was not very pleasing!

Not necessary, but a good idea, so as to avoid any spurious charges going through the boards...

@Svenaustx - What could happen if not removing this battery? Worst case? Not a geek on this but did change RAM on my Macbook Pro "15. Can't remember disconneting the battery back then. Shouldn't it be sufficient shutting the Mac off and ensure it has been used for an hour or so before replacing RAM?

  • These screws are captive in the hard drive bracket.

Which screwdriver do I need for this? I can't seem to get them moving with the Philips one I used for removing the case of my Macbook.

You´ll need a Phillips 00 and a Torx T6 Screwdriver

Lift the retaining bracket out of the upper case.
  • Lift the retaining bracket out of the upper case.

  • When putting the bracket back after replacing the drive, it is easy to put in backwards. If it doesn't seat smoothly, then reverse it and try again.

Lift the hard drive by its pull tab and pull it away from the upper case, minding the cable still attaching it to the logic board. In some revisions of the MacBook A1342, the hard drive bracket may include two rubber brackets (as highlighted in the second picture.) The correct orientation of the rubber brackets is shown in the third picture.
