Yeah, loading tp_smapi wasn't as straight forward as expected, and I don't
wan't to mess with my kernel. I only have XP on vmware for a "just in case"
situation, that's not good to use the widows thinkpad utilities.I'm
surprised there is not straight forward and a "just works" solution for thi=
s
in thinkwiki... for now I just removed he battery until someone else comes
with another idea.
