    • There's a trackpad and keyboard ribbon cable connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • Use a plastic opening tool, an expired plastic credit, or a similarly-thick card to pry up on the upper case, starting in the upper-left corner and working around to the front of the computer.

    • The upper case is likely to stick at its connection above the front edge of the optical drive. If this happens, first free all other sides, then proceed to pull upward on the upper case from either side of the optical drive opening. Here again, inserting a plastic card, guitar pick, etc. can be useful.

    • If you stand the base of the MacBook on one end to get a better look, you may displace the four grey plastic clips that hold the right side of the upper case in place. Don't panic. They slide into slots at the top rightmost edge of the lower frame, above the front edge of the optical drive.

    • During reassembly, make sure the clips on the right side, above the optical drive, click firmly into place. They're different from the clips on the left side, and so normally they require a little firmer pressure to click into place.

    • While holding up the upper case, pull up the black tab on the connector end of the silver ribbon cable away from the connector's socket on the logic board.

    • If there is no black tab, you can also use a spudger to gently pry the connector out of its socket on the logic board. This connector is tall, so be sure to pry straight up.

    • If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy.

    • While you have the upper case removed, it's a good time to remove dust, hair, etc. It's best to use a can of compressed air, though if you use a brush, make sure that its bristles are made of a material (usually animal hair) that doesn't generate static electricity, which can destroy electronics.

    • Upon reassembly, there are 4 grey plastic clips installed in slots running along the top of the frame in front of the optical drive (refer to second and third pictures). These clips must be installed in their slots for their mating tabs on the underside of the right side of the upper case to snap into them.

    • Peel up the foil tape between the fan and the optical drive. Lift the foil tape from the fan side, leaving it attached to the optical drive.

    • During reassembly, be sure to route the cables beneath the tape before reattaching it.

    • If the adhesive on this foil tape no longer sticks, you can hold it in place using a regular piece of tape, but don't block the fan intake.

    • Remove the 2 mm Phillips #00 screw securing the rear corner of the optical drive.

    • When reinstalling this screw, make sure none of the cables nearby get caught under the screw's head.

    • The silver-jacketed Bluetooth cable may be covering the screw. If so, carefully push it aside. You may need to remove the screw holding the ground shield lugs for the two nearby cables before you can move the Bluetooth cable aside sufficiently. This screw is 7mm in earlier models, and may be 4.2mm in Santa Rosa/Penryn and 2009 models.

  24. MacBook Core 2 Duo Inverter Replacement: passo 23, imagem 1 %32

    • Lift the side of the optical drive closest to you, then slide the drive towards you, and up and out of the computer.

    • Follow these steps to reinstall the optical drive:

    • First, slide its side nearest to the rear of the Macbook under the edge of the rear frame to the left of the hinge, while also sliding the optical drive's mounting tab at its upper left corner under the cables at this location.

    • Lower the drive partially into the lower housing. Keep the hard drive cable away from the optical drive bay.

    • Before dropping the drive fully in place, use a spudger to push forward (towards the front of the drive) on the screw hole in the drive's mounting tab.

    • Push forward the slider, which runs along the far side of the drive, to insert the end of this slider into a small channel in the lower case's frame. This helps hold the drive in place.

    • When you push the slider forward, if the screw hole in the drive's mounting tab doesn't line up over its threaded brass insert in the lower case, the front end of the slider hasn't fully inserted into its channel in the frame. Keep trying, but if the slider won't move further to the right, remove the drive to see if the end of the slider is bent.

    • If the front end of the slider isn't bent, it may be slightly too long. Use a pair of fine cutters to clip off the narrower portion of the end of the slider. The optical drive will still remain firmly in place.

  25. MacBook Core 2 Duo Inverter Replacement, C-Channel: passo 24, imagem 1 %32

    • For original Macbook Core Duo and Core 2 Duo models, remove these 3 screws:

    • Two 3 mm Phillips near the right speaker.

    • One 6 mm Phillips threaded through a hole in a plastic finger above the subwoofer.

    • When reinstalling the screw above the subwoofer, be careful not to over-tighten it or the subwoofer's plastic could crack.

    • For Santa Rosa/Penryn and 2009 models, which don't have a c-channel:

    • Remove only the single 3 mm Phillips screw from the right speaker, and skip step 26.

    • Disconnect the antenna cables from the Airport card:

    • If you have an original MacBook Core Duo or Core 2 Duo model, see the first picture, which shows that there are three antenna cables.

    • If you have a MacBook Core 2 Duo Santa Rosa/Penryn or 2009 model, there are only two antenna cables, and the plug/socket for the black inverter cable is in a different location. There may be a square foam piece over the plug/socket for the inverter board connector.

    • Disconnect the inverter cable from its socket by inserting a spudger between the right or left ends of the plug and the socket, and prying gently vertically. Do NOT pry up on the socket--you must pull up on the plug alone, vertically out of the socket. Do not pull in the direction of the cable wires or you will tear the socket off the logic board.

    • The following steps should be identical for both white and black MacBooks.

    • Use a thin plastic card to release the tabs and their clips holding the front display bezel to the display assembly. There are five tabs along the left side of the display bezel.

    • You may find some display bezels are easier to remove if you work from their inside edges, directly adjacent to/above the LCD panel.

    • Don't use a card that cannot be replaced if damaged. The clips can be difficult to remove and the card can bend and break, rendering it useless.

    • Lift up the front display bezel from the top and use your plastic card to free the tabs along the bottom edge of the display bezel.

    • Make sure that your card is between the metal frame around the LCD panel and the display bezel and not touching the LCD panel itself.

    • After freeing all holding tabs, lift the front display bezel away from the display assembly.

    • When reinstalling the front display bezel onto the display housing, you may find it easier to get the tabs and clips to connect if you push on the four sides of the bezel in this order: top, bottom, then the sides (left or right). You may have to apply extra pressure along the bottom side of the bezel to get it to snap into place firmly.

  41. MacBook Core 2 Duo Inverter Replacement: passo 40, imagem 1 %32 MacBook Core 2 Duo Inverter Replacement: passo 40, imagem 2 %32

    • Sometimes when removing the front display bezel, the retaining clips that should remain captive in the LCD brackets come out with the front display bezel. Follow this and the next step to transfer the clips back to the LCD bracket.

    • Use a metal spudger or another thin tool to carefully pry the gray plastic clips off the tabs molded into the front display bezel. A 0.8mm flat screwdriver may be useful for this step. You may find that it's easier to remove some of these clips by prying up on their long sides.

    • Be careful, as the clips are made of thin plastic and are inherently delicate.

  42. MacBook Core 2 Duo Inverter Replacement: passo 41, imagem 1 %32 MacBook Core 2 Duo Inverter Replacement: passo 41, imagem 2 %32

    • Insert one end of the retaining clip beneath the edge of its recess cut into the LCD bracket.

    • Use the edge of a spudger to push the short hook tab on the underside of the other end of the retaining clip into the recess cut into the LCD bracket.

    • The second picture shows a retaining clip properly installed.

    • You may find it easier to get the short hook tabs on the underside of each end of the clip to fit down inside their cutout in the LCD bracket by first very slightly bending down the two ends of the clip, but be careful not to bend the clips too much--only a slight bend is needed, and too much force will break them.

    • While holding the display down with one hand, use your other hand to lift the left end of the clutch cover off the clutch hinge and guide the inverter cable and AirPort cables through the gap in the clutch cover. If the cables snag on the two hooked tabs on the inside end of the clutch cover, free them carefully.

    • It may help to wiggle the clutch cover as you pull it up from the display.

    • During reassembly, make sure not to pinch the black inverter cable or the Airport wires when snapping the left end of the clutch cover back into place. To avoid pinching, it may help to lift up and hold these cables and wires in place at the top of the hinge, rather than leaving them running along the sides of the hinge.

    • Lift up the right end of the clutch cover while guiding the display data and iSight cables through the gap and the two hooked tabs at the right end of the clutch cover. If the cables snag on the two hooked tabs, free them carefully.

    • Lift the clutch cover off of the display assembly.

    • During reassembly, avoid pinching the display data and iSight cables. While guiding the right end of the clutch cover into place, but before snapping it down, guide these cables between the two hooked tabs inside the right end of the clutch cover, and up into the curved area of the clutch cover, above the hinge.

    • Also avoid pinching the backlight wires (with the white connector on the end, plugged into the right end of the inverter). They should run under the upper right edge of the clutch cover. In some models, the two wires are gray and black, and in others they're white and pink. They lead into a hole in the lower right edge of the LCD to the backlight.

Awesome site and awesome guide. This exteneded the life of my MacBook. I can't thank you enough!!!!

For about 3 years I had been dealing with my screen backlight shuting off. I would then dim the screen up and down until I could get it to stay. Sometimes it would work the first time other times I would be doing it for 10 minutes and other times I would give up for a few hours and come back and the screen would be on again. It would also do this sometimes when I opened the laptop at a certain angle or bumped the computer.

Well after these years very annoying behavior, my screen wont turn back on. I can see my desktop when I shine a light on the screen and hear the fan running so I know the computer works fine.

I've tried unpluging the inverter board to see if it was a loose connection, but that didn't work. I tried wiggling it around until the screen turned on and nothing.... Please help!

Is this a problem with my inverter or the inverter cable? Or the backlight cable?

What parts should I buy?

Hi, I've had the same trouble. Today I solved with a spray electronic cleaner :)

Hi everybody! Last year bought a new inverter, new cable and other stuff and replaced. Problem not solved, screen still turning black. Thinking to get a new display, but today bought spray electronic cleaner, sprayed over the display data cable (https://d3nevzfk7ii3be.cloudfront.net/ig...). Problem &&^&^$^ solved! :) Time: 15 mins, money: 5$. Good tutorial tho! :P

These are a very comprehensive set of instructions and give a really good grand tour of the innards of a MacBook 8. They are also useful for replacing the hard drive or the optical drive.

Couple of hints:

1. Have on hand some canned compressed air - the inside of a laptop is generally quite full of dust and fluff.

2. Also have on hand some contact cleaner spray (do NOT use degreasers/lubricants/anti rust sprays such as RP 7 or WD 50). Contact cleaner sprays generally only contact isopropyl alchohol. It's good to give exposed contacts a bit of a clean - even grease from fingertips can affect conductivity and hence performance. (If possible, use powder free surgical gloves).

3. Make sure you have the right tools (don't skimp - buy the tools set from iFixit). Not using the right spudger on a plug could be the cause of irreparable damage to the circuit board.
