windows 7 - Switch from battery to powerpack causes strange messages and slowdown of computer

A problem that has flabbergasted me now for a while. On a Dell Latitude E6410, everything works swimmingly when the computer runs on battery. the moment that one inserts a powerpack (e.g. connects the laptop to the electricity net), two things happen (unclear if correlated):



  • After between 10-40 minutes - the computer will become very slow and unresponsive. Initial checks don't indicate that this has to do with back-up software (e.g. dropbox or Mozypro) or virus scanner, but cannot fully rule out. This is the main problem.


  • Also - the moment that the power pack is inserted - eitehr Intel Rapid Storage Technology will "detect port 1", or if the former is disabled, Windows will suddenly detect a non-existing D: Drive / DVD drive. (which makes me wonder whehter it misreads the battery pack as an external storage location???). As said - not quite clear to me whether correlated with the problem per above, and if so, what the causal mechanism is, why the computer slows down...



Anyhow - this completely confuses me - and would love to hear any thoughts on the cause, furhter diagnosis and/or and ideally resolution of this problem...


Many thanks in advance,
