Hi Roger and Bill,
I posted my problem with SD cards back on 29 July 2012.
The problem still exists only when attempting to insert card, which takes a few tries before the red light stays on and it reads the data on the card.
Curiously enough, once the card is received it stays connected forever, after the KB is turned off and on many times.
It occurs with any card I use.
The spring is not consistent in its action with the insertion of the card, as well, also, too !!!
That was when I was advised by others to try the contact spray!!!!!!!!!!

See Ya

Ray
