This problem has been going on for years & Dell refuses to deal with it. I guess Michael is just too busy trying to take his toys & go home. Everybody in my office is on MacBooks. i have to use a PC because of all the legacy things I deal with, but I can tell you - my next machine will be a Mac running bootcamp. This should be a simple problem to fix - that is - if anybody at Dell or Cypress cared.
Bottom line - we all bought very expensive machines - they have your money.
