MacBook Unibody Model A1342 Upper Case Replacement

Replacing the upper case requires the removal of nearly every component in your MacBook.

Image #1

Edit Step 1 Lower Case  ¶ 

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

Image #1

Edit Step 2  ¶ 

  • 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.

Edit Step 3 Battery  ¶ 

  • 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.

  • While holding the display and upper case together with your left hand, remove the remaining T8 Torx screw from the lower display bracket.

  • Before retightening the T8 Torx screws, close the display and adjust it so that the back edges of the upper case and display are aligned and the gaps at the ends of the hinge are equal.

Image #1

Edit Step 38  ¶ 

  • Be sure to hold the display and upper case together with your left hand. Failure to do so may cause the freed display/upper case to fall, potentially damaging each component.

  • Remove the last remaining T8 Torx screw securing the display to the upper case.

Image #1

Edit Step 39  ¶ 

  • Grab the upper case with your right hand and rotate it slightly toward the top of the display so the upper display bracket clears the edge of the upper case.

  • The display data cable may cause the upper display bracket to get caught on the upper case. It may be helpful to slightly rotate the upper case away from the display for more clearance.

  • Rotate the display slightly away from the upper case.

Image #1

Edit Step 40  ¶ 

  • Lift the display up and away from the upper case, minding any brackets or cables that may get caught.

Image #1

Edit Step 41  ¶ 

  • There are four orange and black rubber inserts that the hard drive sit into. one side has full circles and the other side has half circles. ( The other side of the half circles are located on the hard drive bracket that was previously removed).

  • The new upper case may not have these inserts. e sure to remove them from the old and insert into the new.

  • The inserts are easily pried out with a spudger or a flat tipped screwdriver. They are not glued in, but instead have notched sides to hold them in place.

Image #1

Edit Step 42 Upper Case  ¶

  • Use the following steps to install the old trackpad into your new upper case.

  • Reinstall the T6 Torx set screw until it is flush with the aluminum bracket surrounding the trackpad.

  • Place the trackpad back into its void in the upper case, being sure the lower tabs are inserted underneath the keyboard side of the upper case.

  • Be sure the trackpad ribbon cable is not pinched between the trackpad and the upper case.

Image #1

Edit Step 46  ¶ 

  • Reinstall the four silver Phillips screws securing the trackpad to its steel brackets.

  • Loosen all four silver screws about 1/16th of a turn.

  • Flip the upper case over and adjust the position of the trackpad until the gap between the trackpad and the upper case is evenly spaced around the perimeter of the trackpad.

  • Tighten the four silver screws to hold the trackpad in place.

  • Repeat this process until the trackpad is perfectly positioned in its void on the upper case.

Image #1

Edit Step 47  ¶ 

  • While repeatedly pressing the trackpad to simulate clicking, tighten the T6 Torx set screw until the trackpad no longer wiggles freely.

  • Do not over-tighten the set screw, as the button will cease to click at a certain point. Adjust the set screw until the movable side of the trackpad has minimal play.

Comments Comments are onturn off

NOTE: Ensure you don't pull the entire assembly straight up or the base will come off the logic board. Use an extremely small straight blade screw drive to gently loosen the inside assembly while gently pulling on the wire bundle! Will save buying a new logic board!!!!

Some of the screws are extremely tight, I stripped at least 6 Phillips screws during the upper case replacement.

Great guide! My only comment would be to remove the battery first. It makes dealing with the keyboard ZIF cable much easier to install/remove.

I went a little further and, although is not recommended, I unglued the Upper case from the keyboard and replaced it after a coffee accident. Had to reglue the new keyboard back in place and it´s working. The fix is not very good (keys dont go up as when originally assembled) so I´d recomend you to change the whole upper case instead of trying to change the keyboard as you may actually break it.

is there a way i can rip the keyboard of the upper case??? and then later put it back together? look forward to spray painting my laptop.

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, · Reply

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

brilldoctor, · Reply

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.

naamol, · Reply

Not necessary?

hikkymemo, · Reply

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!

jljordanweb, · Reply

Hi, i have an issue with the screw in the middle: it is blocked and the top is now damaged... Any suggestion?

Corrado, · Reply

you can actually stop disassembling now and try to replace it now. after removing two t6 screws it came off pretty easily

grze, · Reply

Good tip, thanks! I skipped ahead to step 17 and had no problem getting the magsafe board out from under the logic board and the new one installed. Saves a lot of work disconnecting connectors indicated as Fragile!

matt15,

Since this kind of connector and very fragile and easy to damage even with a spudger I use a needle that I insert in the front side of the connector, between the connector and the socket and only apply a little pressure while lifting up the needle. The connector will then pop up from one side. Repeat the procedure for the other side. With this method it's impossible to damage the connector. I adopted this method after ruining two or three connectors using the spudger.

lemerise, · Reply

HELP! Both the connector AND socket detached from the logic board! Is it possible (barring micro-surgery) to reattach the socket to the logic board?

John Watson, · Reply

While these connectors are very delicate, a new upper body case will have new connectors already installed. I slightly broke two connectors while removing them.

Also, the connectors have a notch underneath (on the logic board) for the corner of the spudger to fit into. The hard part is that you cannot see the notches until the connectors are removed.

I used pointed tip of one side of the tweezers from the ifixit Home Tech Toolkit. I found this thinner pointed tip better than a spudger for hitting that notch in the socket underneath the connectors. Since this is a metal tool, I pried very gently and I was working on a MacBook with the battery taken out entirely (early on as suggested in the video) and was also using an Anti-Static wrist strap. I found the spudger broke one of the connectors because it's relatively thick plastic, and put too much pressure under the cables before the tip could reach the plastic block of the connector. The pressure under the cable popped the wire contact right through the top of the plastic block connector. (it was OK this connector broke since I didn't need to reuse it--my replacement keyboard/upper case came with its own cables.)

Because the tips of the tweezers are angled, I felt I had better control of the torque I was applying than if I used a jeweler's flathead screwdriver.

I broke a speaker connector on this step. I found it easier to use a tiny flathead screwdriver to gently pry these connectors up.

I had to remove the battery again to insert the keyboard ribbon cable. I just couldn't get the right angle and force otherwise.

asciimo, · Reply

When reassembling make sure this cable is really deep in it's socket. (Use some force with the spudger wedging it in between the cable and battery). If you don't, you won't be able to power up the board. I had 2 logicboards that I thought were dead, but it turned out the cable was not inserted enough. Jump starting them with the jump pads did nothing (with or without cable connected), but connecting the cable properly made the board come alive. Really check this!!

You sir, just saved my day! Switching boards between two mac and I thought I broke the two at once... This should be documented on the manual!!

jorgecarleitao,

Thanks for your help!!! I thought I did the replacement wrong. Greetings from Peru.

Lalo Gonzalez,

Note: the 2009 and 2010 model differ here. On one the 3 point connector is left and 2 point is right, on the other one the 3 point connector is right and 2 point is left.

I found this while installing several logicboards for A1342.

Peterdk, · Reply

Just lift the tab up slightly to release the clip that secures the data display cable. Then the cable will slide out easily.

matt15, · Reply

(When re-installing) Before screwing down the logic board, go around the edge and make sure no cables are caught underneath, remember there are 11 of them, 12 if the battery is present at this point.

kenhtanaka, · Reply

I reassembled the macbook A1342 using this guide and everything is perfect, except that if I shut down the computer and power it up after 1hour or so, I have to press the power button a few times before it starts. What could I have gone wrong? I checked the magsafe connector and it seems to be firmly seated. :(
