  • Answer to: spilled oil over my keyboard

    As far as I'm aware all 15" unibody use identical keyboards (same model number of computer since 2008). Maybe 2012 model different. That said I was able to remove milk from 20-25 keys using an x-acto knife a very pointy tweezers and "canned air". The problem with these keyboard and impossible to repair is that the three layers of plastic are glued together! In the old days you could peel apart the layers and clean with dish soap and re assemble. If you have fewer than 10 affected keys it would be worth the effort of a top-side fix as long as you realize the risk of needing to use an external USB keyboard while the replacement comes should you break it. If you look at any single key contact you can see the two layers with the crossing traces going to the center. The process to clean out the milk etc. is this: On the TOP LAYER, determine the direction of the trace, example horizontal. Now make two in incisions on either side of the center cutting in that same direction on either side of that trace. Cut through ...

  • Answer to: Lateral hit, MBP shuts down from time to time.

    I had an identical problem; eventually realized it only had the problem when the battery which was bloating was installed. replaced battery, problem solved.
  • Answer to: Is it possible to replace JUST the keyboard?

    I have done this repair several times. I had somebody say that apple did it for them for $130 but now that I think about it, that HAD to be pre unibody! When i replaced my own keyboard, I put tinted tape over different groups of keys (yellow alpha, green numbers etc). De-tunes the brightness and makes the mac much more eye friendly. It's a shame that the film layers on the new keyboards are glued together. I've repaired about 10 keyboards in the past without having to replace by separating the layers and cleaning them. Usually if liquid gets into MacBook Pro keyboard it will dissolve traces or the "glued" interconnects making the keyboard a total loss. Fortunately. $35 and an eBay account will get you a new one. Unfortunately a "level 8" difficulty of repair. Almost impossible to avoid stripping one of the 60 or so screws. One of the ones on the keyboard I just removed had only 40% of the screw indent making it nearly impossible to remove. Use a good set of hardened steel bits! -awr Update: See my markup: the...

  • iMac Intel 20" EMC 2105 and 2118 Front Bezel Replacement

    The iMacs I've taken apart open simply with a magnet. I made a video to show exactly how the latch works inside. You do need a strong magnet like the hard drive internal magnet suggestion however they can be found in many places, just look for 'rare earth' or 'neodymium' and you'll find one. probably .3" cube would be big enough.

    there is the video that shows how the latch works. of course you may need TWO magnets to do both latches at the same time.

  • iPhone 4 Display Assembly Replacement

    I was able to replace the LCD panel and digitizer as separate units, but they were separate to start with. That being said, it's definitely more challenging. it's pretty easy to get the two attached to each other, just takes 2 drops (1/10th of one ml) of clear oil. i used a 1/2cc syringe to spread a thin line down the center. came out absolutely perfect. without the oil it's horrible. No contrast and just moiré galore.

    The added difficulty comes from getting the two parts to behave while assembling, since they aren't glued, they slip and slide around, and air can get in on the edges and no more dark black.

    i tried first with water; terrible results, it interfered with the capacitive touch; ouch. So, i got some practice today re-assembling the phone. the guide was priceless—this is one of the most complex teardowns of ever. i used 12 compartments of an 18-comartment bin.

  • iPhone 4 Speaker Enclosure Assembly Replacement

    'and then there were THREE' yup i broke off one as well. hint on re-assembly; put in the speaker box, and working from left to right, apply a fair amt of downward pressure and use a tiny flat-blade screwdriver to push the tip of the emi fingers toward the speaker box, go left to right so you can put in the screw on the right side when done.

  • iPhone 4 Display Assembly Replacement

    one of the cables has a fold or something making it 'double' so there are really THREE cables that must be fed through the hole (one just doesn't go anywhere). I used a tiny tweezer to aid with re-routing the cables and it was FAR easier.

  • iPhone 4 Display Assembly Replacement

    i tried using the 'only loosen' method on half, and found out because of the washers, they interfered during reassembly. it was very easy to replace them by setting the phone down on its side (propped up so as not to tip) and use a tweezer to put in the washer then screws, it was simple.

  • iPhone 4 Logic Board Replacement

    be careful when putting the logic board back in: i trapped the lower antenna cable under it (see step 11). Also, it 'hooks in' at the top and rotates down; there is a notch cut into the outer case to capture the top of the motherboard.

  • iPhone 4 Rear Panel Replacement

    using something like the 18-compartment tray will GREATLY help with this one; there are over a dozen groups of parts. For re-assembly having a digital calipers to measure the 2.4 vs the 2.6mm screws also helps greatly.
