CAUTION: If you plan to leave the notebook unattended during
discharge, save your work before starting the discharge
procedure.
To fully discharge the battery pack:
1. Select the power icon on the taskbar or select Start > Control
Panel > Performance and Maintenance icon > Power Options
icon > Power Schemes tab.
2. Record all settings in the Plugged In column and all settings
in the Running On Batteries column, so you can reset them
after calibration.
3. Use the drop-down lists to set each item in both columns to
Never.
4. Select the OK button.
5. Disconnect the notebook from the external power source, but
do not turn off the notebook.
6. Run the notebook on battery power until the battery pack is
fully discharged. When the battery pack is fully discharged,
the battery light turns off and the notebook shuts down.
If you use the notebook occasionally during the discharge
procedure and have set energy-saving timeouts, expect the
following performance from your system during the discharge
process:
■ The monitor will not turn off automatically.
■ Hard drive speed will not decrease automatically while the
notebook is idle.
■ System-initiated Standby will not occur.
