Step 3: Discharge the battery
The computer must remain on while the battery is being discharged. The battery can discharge whether
or not you are using the computer, but the battery discharges faster while you are using it.
●
If you plan to leave the computer unattended during the discharge, save your information before
beginning the discharge procedure.
●
If you use the computer occasionally during the discharge procedure and have set energy-saving
timeouts, expect the following performance from the system during the discharge process:
◦
The monitor does not turn off automatically.
◦
Hard drive speed does not decrease automatically when the computer is idle.
◦
System-initiated Hibernation does not occur.
