Dell Latitude E5540 :: Doubles Letters And Spaces Randomly?

I regularly find that,  with a  single keystroke, my brand new Dell Latitude e5540 laptop randommly produces 2 spaces (most often) and double letters (sommewhat less often than the doubled spaces, but consistently and  predictably). The faster I type, the more oftenn the errors occur... I have  found  it to be an issue of how hard I strike the keys. The keys  controlled by my dominant right hand are most often affected whereas those controlled by my pinkie fingers NEVER have been affected.

I  amm only one of many employees at my place  of  work who all are experiencing the same problemm. I have asked repeatedly for Dell to let me know the extent of this problem and whether they have a recall of this model (which, as far as I can tell, is pervasive with this particular mmodel). My persistent questions have never been answered by Dell, despite numerous contacts with 3 different agents.

P.S. If you notice double letters where there should  be single letters or   extra spaces in this e-mail and this post scrippt, please read on for the reasonn: I am using the brand new Dell Latitude e5540 computer our school system recently purchased to write this e-mail. I have simmply givven up  editing my typing... you're getting the spontaneous errors caused by this computer so you can see for yourself and hopefully to motivate Dell to fix the problemm soonner, rather than latter.

  IMPORTANTLY, if you are having similar problems with YOUR BRAND NEW Dell Latitude e5540 laptop you specifically will NOT have tthese problems if you use an external keyboard... it only occurs with the laptop's built in keyboard) PLEASE send me your servvice  tag (S/N) nummber from the bottom of your Delll LLatitude e5540 computer and I will include your commputer in my conntact with Delll about this problem. (It is  a problemm of this particular model... I have never experiennced this before with any other computer).
