I have an M0110 with intermittent keys.  Some of the keys don't work, a handful work just fine.  Some I can press hard and they'll register, others I have to press at an angle.

Could it really be that most of the key switches are bad?  Or could it be something else?  I gave it a good hot bath, but no change.

I suppose I could swap a working keyswitch to the spot of a not-working one.  That would help me determine if it is indeed the switches and not something else.
