[A6] dead key/switches/aftertouch - advice on fixing/opening

[Mike Schultz]

I had crud in my key contacts after less than a year, and I keep my  
space clean.  Just be methodical when taking it apart, there aren't  
any tricks that I recall.  Once you have the fatar keyboard out, pull  
up the elastomer and swab the contact surfaces with denatured  
alcohol.  If you happen to have some compressed air handy to blow it  
out, that doesn't hurt.

There are a few cables coming off of the keyboard, the assemblers  
were pretty liberal with the silicone goop but re-seat them just the  
same.  Test and re-goop if you are working after that.

I don't know the specifics of the switches, but expect to replace.   
Check digikey/mouser for a form/function equivalent.  Many vendors.
Good luck
Mike
