Anyone ever taken apart an A1016 wireless keyboard? The letter-keys "a" and "z" on my A1016 wouldn't type. I keep a clean keyboard, occasionally brush all keys horizontally and vertically with a (new, never used but for this purpose) paintbrush. Then use the brush attachment on the vacuum to suck out what it can. Sometimes use the vacuum in exhaust to blow warm air into board. Did this. Didn't help. Then read about popping off the keys, a & z, and was rather surprised to see, yes, dirt and a few hairs. Swabbed the area with Q-tips, got all clean. I know you can do this, pop keys (keep a board handy or keyboard screen capture to know where to put keys back on), just pry off with a flat blade, clean to your heart's content, replace keys. This I did. Still no a & z. After saying **** several times, I set keyboard outside in strong sun. I thought maybe something would expand in heat. (No way could there be moisture inside, I am too neat, but what the ****, it was worth a shot.) After a few hours I got a & z back! Overnight, had some trouble the next morning, set board in sun, typed on it in a better position and all was, has been, well. Ok -- after "cleaning' my board, in strong sun I noticed a bit of dust in the clear sides and bottom. Well, this will be easy, I'll just undo the three tiny screws holding the lucite caseing. I've every screwdriver imaginable, but not this tiny one! None of mine will fit. Am working on this, for the A1016 is something built, put together, has screws for a reason, so there must be a way to get the board out of the lucite housing. Just undo a few simple screws, clean the caseing. Has anyone done this? Is there a "special" Apple tool? I'm working on getting the proper driver. When fussing I've no a & z to friends it was suggested I get one of those Radio Shack cans of compressed air, use the long red thin tube and blast away. That might "clean" the bottom of the unit a bit. As well, something I am going to do when the chance comes up, ask at the local Mac store how they take a keyboard apart. I think they've a special screwdriver. Anything built can be taken apart. If you can get the lucite away from the board, that bottom housing can be cleaned. Anyone ever done this?
