It would have been better if the reader has shared with us how old is the battery and when the problem started?

does it started after you calibrated the battery? If yes, we would like to know how you calibrated the laptop battery? used some tool or on your own?

Also, which operating system you are on? I am guessing it to be windows 7 as there are some issues of this kind faced by many users.

If the problem started after the calibration, it may be a result of bad or messed up calibration. If that is the case, you may need to calibrate again.

May be other members too can help him out.
