Step 3: Discharge the battery
The device must remain on while the battery is being discharged. The battery can discharge whether
or not you are using the device, but the battery will discharge faster while you are using it.
●
If you plan to leave the device unattended during the discharge, save your information before
beginning the discharge procedure.
●
If you use the device occasionally during the discharge procedure and have set energy-saving
timeouts, expect the following performance from the system during the discharge process:
◦
The monitor will not turn off automatically.
◦
Hard drive speed will not decrease automatically when the device is idle.
◦
System-initiated Hibernation will not occur.
To discharge a battery:
1. Unplug the device from its external power source, but do not turn off the device.
2. Run the device on battery power until the battery is discharged. The battery light begins to blink
when the battery has discharged to a low battery level. When the battery is discharged, the battery
light turns off and the device shuts down.
