User's Manual

 If your battery is charged in a cold (less than 41∞F/5∞C) or very warm (greater than 122∞F/50∞C)
environment, it is possible that the Battery Charge LED will indicate that the charge has
stopped; however, this does not necessarily mean that your battery is fully charged.
Tip 5. Prevent data loss
Follow these guidelines to prevent data loss when removing your battery or storing your computer:
 You will lose data if you remove the battery while the computer is operating or suspended. To
prevent this, shutdown your computer or put it into hibernate (suspend-to-disk) mode before
removing your battery.
 If you plan to store your computer for more than a few days, shutdown your computer or put it
into hibernate mode. Remove the battery before storing the computer.
Tip 6. Clean terminals
 Dirty terminals can be a cause of charging problems. Clean battery terminals with a cotton swab
dipped in isopropyl alcohol. Make sure that the alcohol has evaporated before reinstalling the
battery.
Tip 7. Storing batteries
 Store the battery within the recommended temperature range: 10∞C to 30∞C (50∞F to 86∞F).
 Unused or stored batteries can lose power over time. When you install a battery that has not been
used for awhile, connect external power to the computer and fully charge your battery.
 Battery calibration may increase the capacity of a battery stored for a period of time. For
information on calibrating the battery, refer to Battery Calibration.
 It is recommended that the battery is recharged every six months while in storage.
