Batteries
The batteries take much longer than three hours to charge
•
Under moderate temperatures, about 21°C (70ºF), the computers
battery takes 3 to 4 hours to completely charge. Under extremely
cold or hot temperatures, however, the battery can take up to 16
hours to fully charge.
The batteries dont last very long
•
Over time, your battery may develop memory effect. This occurs
when the battery is partially discharged and recharged repetitively
without full discharge. A partial or shallow discharge means that
you use less than 50 percent of its capacity before charging.
•
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 charging light doesnt flash
•
Verify that a battery is installed in the unit.
•
Check AC power connection.
•
Check the Power Profiler to see if the gas guage is full.
The ambient temperature rises rapidly when charging the battery
at room temperature
•
This is normal. The internal ambient temperature is always 0º to 16º
higher than the external ambient temperature. Ambient temperature
is not used for charge termination criteria.
