I'm typing this post from an AEKII that I've recently pressed into service with my Quicksilver via a Griffin iMate. I've had this keyboard for a while-although admittedly not used it extensively and not for the sort of typing I've been doing recently. All of my past use with this particular keyboard has been on ADB equipped Macs, although as I said I've not done a huge amount of typing on it. To make a long story short, I decided to press this keyboard into service for dissertation writing duties, and in a day or so of using it I've noticed a very annoying problem. Specifically, the "P" key is very difficult to actuate. There's no discernible difference in pressure or feel on the key, but it only seems to work on one out of every 10 or so presses(if that often). Sometimes, it works with no discernible problem and with no additional pressure(I haven't measured recently, but would guess that I type at 40-50 WPM with a normally functioning keyboard, and could probably type faster with this one if it worked normally). At other times, I have to really bang on the key to get it to register. I've pulled the cap and given the switch a good shot with compressed air. Is there anything else I can do to potentially fix the problem? If I could find a replacement switch, it would be great. I'd also be open to swapping it out for a less-used switch like one of the F keys where I really wouldn't miss it. If it's of any relevance, this is a model M3501, serial number AP0340RJ%M0312. It has the "clicky" Alps switches and not the cushioned ones of some of the AEKIIs, and the height adjustment slider is white. I've used the iMate before with my other AEKII(which has the cushioned switches) but would really like to get it working at 100% since I prefer "clicky" switches for serious tying work. Any thoughts on any of this? (or should I just drive to Lexington tomorrow and buy a USB Unicomp Spacesaver M at the factory to get my clicky key fix) ---------- EDIT: Apparently I have the "damped" Alps switches as per this reference http://deskthority.net/wiki/Apple_Extended_Keyboard_II Mine was Made in the US, and has the "s" in a square on the label. I'm not sure this makes any difference for repair purposes, and I guess also I'd forgotten how loud a model M is.
