pack is fully charged, select Start > Control Panel >
Performance and Maintenance icon > power Options icon >
Power Schemes tab.
2. Make a note of the 2 settings in the Plugged In column and
the 2 settings in the Running On Batteries column so that you
can reset them after the calibration.
3. Change the settings in both columns to Never.
4. Select the OK button.
5. Disconnect the notebook from AC power, but do not turn off
the notebook.
6. Run the notebook on battery power until the battery pack is
fully discharged. (The battery light begins to flash when the

notebook is off.
2. If the notebook is off, turn it on when the battery pack is fully
charged and the battery light turns off.
3. Select Start > control Panel > performance and Maintenance
icon > Power Options icon > Power Schemes tab.
