Replacing a defective fan will keep your laptop running cool.

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?

Gregoire - Ответить

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.

hi, i just got back from the apple store and they are really keen for me to upgrade to a new laptop since my battery is old and the screen is cracked, so glad i found ifixit i would love to upgrade this puppy! gonna make it a real sleeper! styler hall wrote about sticking 16 gb of ram in his a 1342 ? is this a simply mather of ordering 3 4gb sticks ?aslo i currently have 4 gb and would like to upgrade to 8 ( or indeed 16) does that mean i need to buy all new sticks or can i continue to use the old one and stick a new one next to it ?

thanks again mick van aar, perth western aus.

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!

Gregoire is right. The 8 screws are absolutely NOT identical, I’m looking at them right now, weeowey weeowey.

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?

John Morley - Ответить

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.

Rather than running your fingernail down the sides to free up the retaining clips, I found that using an old credit card, inserted about 1/4”, to run along the left and right side popped those end retaining clips right off with no problem. You may need to twist the card slightly when in the middle area to help pop those off.

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.

  • 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.

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?

i used a metal pry and noticed some sparking when i disconnected the battery. replaced ram. now it wont turn on. did i fry it?

Use a spudger to pry the AirPort/Bluetooth ribbon cable connector straight up off the logic board.

Use the flat end of a spudger to pry the fan connector straight up off the logic board. It is useful to twist the spudger axially from beneath the fan cable wires to release the connector. The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

I think I broke it off the board. Is this fixable?

I broke the socket off the logic board, but it is fixable. I succesfully welded it back but it's a very tricky thing to do, even with the right tools, the socket is plastic made so it melt easily and you need very good eyes because soldering iron and magnifying glass are very annoying to use together. If you are not confident to do the right thing, dont do it ! Check your entourage, maybe you have electronic buffs who could do it right...

    • One 7.1 mm Phillips

    • Two 5.3 mm Phillips

The two 5.3 mm Phillips screws are so tight, that I can’t open them. I’ve tried to apply some oil with an Q-Tip. Has someone an other clue?

Take a look at this guide for removing stripped screws, How to Remove a Stripped Screw, and see if any of these options might work for your particular screw.

Replaced the fan with an used one. After booting the fan made a very loud sound as if it was running on max speed. A SMC reset fixed the issue and the fan returned to normal speed and sound.
