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.
