•
Allow the system to remain idle for one hour with the AC adapter connected
to the device.
•
The Battery Power LED lights when the battery starts charging.
•
If the battery still fails to start charging 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 20
°
C (68
°
F), the device
’
s battery takes
approximately 4 to 5 hours to completely charge.
•
As the battery temperature approaches the ends of its temperature range (5
°
C/ 41
°
F to 50
°
C/122
°
F), it may take longer to charge the battery.
The batteries don’t last very long.
•
Calibrate the battery. If your battery is new or has not been used for several
weeks, calibrating the battery accurately sets the gas gauge.
•
As your battery ages, its maximum capacity 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.
•
To meet ENERGY STAR

requirements, Wake on LAN is enabled by default.
If running on battery power this may decrease battery run-time. To change
Wake on LAN settings, open the Device Manager, Network Adapters and
select the LAN device. Open the device Properties and select Power
Management. Disable the Wake on LAN setting by unchecking. Allow this
device to wake the computer.
The gas gauge isn’t full after charging the battery.
•
This may indicate that the charging process terminated prematurely.
The gas gauge reads “full,” but t
he charging LED 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 you are using it for the first time, you will need
to calibrate it (see Battery Calibration) 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.
