Batteries

The battery does not charge
 To prevent possible damage to the battery, the system will not allow a charge if the battery
temperature is extremely hot or cold (such as in a closed, unattended vehicle). If possible,
charge the battery in a location with a moderate temperature of around 20∞C (68∞F).
 If possible, turn off the computer while the battery is charging.
 If the battery is new or has been stored for a week or more, follow this procedure:
1. Make sure the computer is turned off.
2. Unscrew and open the battery cover, then remove the battery.
3. Connect the AC adapter to the computer and an AC wall outlet, and then turn on the computer by
pressing the
Power Button. The Power Status LED will be solid blue when connected to
external power .
4. Let the computer complete the boot process. Then reinstall the battery and replace the battery
door.
5. Allow the system to remain idle for one hour with the AC adapter connected to the computer.
The
Battery Status LED is orange when the battery starts charging.
6. If the battery still fails to charge after an hour, remove the battery, wait several seconds, and then
install it again.
If the battery does not begin charging within several minutes, return the unit for service.

The batteries take much longer than seven hours to charge
Under moderate temperatures, about 21∞C (70∫F), the computerís battery takes approximately 3 hours
to completely charge while suspended and 3-5 hours to charge while powered on. Under extremely
cold or hot temperatures, however, the battery can take up to 16 hours to fully charge.

The batteries donít last very long
As your battery ages, the maximum capacity that it can hold naturally decreases, and even the best
maintained batteries eventually need to be retired. Consider replacing the battery if you are not getting
the usage you need from it.
 The gas gauge isnít full after charging the battery
 This may indicate that the charging process terminated prematurely.
 Calibrate the battery to align the gas gauge with the battery capacity.

The gas gauge reads ìfull,î but the charging indicator light is still lit
If you charge your battery daily, rely on the gas gauge reading to determine battery capacity. The
charging process may continue even if the gas gauge reads full. External power can be removed
because the battery is virtually full.
 My battery seems to have less and less capacity
 If your battery is new, or if your are using it for the first time, you will need to calibrate it prior to
using it.
 As your battery ages, the maximum capacity that it can hold naturally decreases, and even the best
maintained batteries eventually need to be retired. Consider replacing the battery if you are not
getting the usage you need from it.
