Calibrate the notebook PC battery
Short discharges and recharges do not fully synchronize the battery's fuel gauge with the battery's state-
of-charge. This can result in the amount of power available in one cycle being less than expected or the
battery meter being inaccurate.

can be calibrated by following these steps:
Step 1 - Disable the Windows Power Management
2.
Click Screen Saver tab, click Power button.
