I have a Clevo 2700T and mine died after about a year.  It got to the point
of apparently charging fully, and then going down to about 1:04hour and 
then suddenly saying that it only had 4 minutes.

I replaced it with a new 8 cell battery and I now get 3hours 40minutes which
is wonderful.  It cost #80, but it is very useful.
