 The flat cable between the keyboard controller and the keyboard is too
 short.  This can cause intermittent or complete loss of function of the
 keyboard.

 At the expense of at least a half hour's labor to disassemble the keyboard
 and reassemble it, and possibly removing the screws holding the keyboard
 down so that it can be repositioned, it may be possible to recover
 functionality by reseating the cable in the zero insertion force connector
 (which is not entirely obvious how it works if you've never seen it.

 This rework is painful enough, however, not to be for the fainthearted or
 fumble-fingered.  It is the hardest part of the laptop to work on, short
 of resoldering components.  Please contact us before attempting this in
 the field.

 To be fixed in B3 by slightly lengthening the cable to allow more assembly
 tolerance.
