Battery FAQ
How do I completely discharge the battery?
Use the computer with battery power until it shuts down due to a low battery. Don’t turn off the computer by yourself even when you see a message that in- dicates the battery is critically low, just let the computer use up all of the bat- tery power and shut down on its own. Disable the Power Options functions in the Control Panel, especially any Alarms (unclick the tickboxes - see 3 - 21) and Schemes (change all the settings to Never - see page 3 - 16). As the battery nears the end of its life save and close any critical files.
How do I fully charge the battery?
When charging the battery, don’t stop until the LED charging indicator light changes from orange to green.
How do I maintain the battery?
Completely discharge and charge the battery at least once every 30 days or af- ter about 20 partial discharges.
