I had something similar happening to me. I thought it was a battery monitor program I had installed but I never really narrowed it down to that. My battery problem has cleared it's self up believe it or not. I am running WM2003 as well. My X5 came with WM2002. I never did experience any real issues, from what I can remember, when I had WM2002. I am sorry this is not going resolve your issue, just thought I would let you know that you are not alone here and it could very well clear up on it's own. I could very well have issues down the road but as of right now everything is working AOK.
