Damaged Battery Warning
Should you notice any physical defects (e.g. the battery is bent out of shape after
being dropped), or any unusual smells emanating from the notebook battery, shut
your computer down immediately and contact your service center. If the battery has
been dropped we do not recommend using it any further, as even if the computer
continues to work with a damaged battery in place, it may cause circuit damage, which
may possibly result in fire. It is recommended that you replace your computer battery
every two years.
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 indicates the
battery is critically low, just let the computer use up all of the battery power and shut
down on its own. Disable the Power Options functions in the Control Panel, espe¬cially
any Alarms (unclick the tickboxes - see 3 - 9) and Schemes (change all the settings
to Never - see page 3 - 4). 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 after about
20 partial discharges.
