The batteries take much longer than three hours to charge
• Under moderate temperatures, about 21°C (70ºF), the computers
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 dont last very long
•
Deep cycle discharge the battery using the Battery Maintenance
application. If your battery is new or has not been used for several
weeks, deep cycle discharging the battery over two or three
consecutive weekends may substantially increase its capacity.
• 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.
• You may have a defective battery. Check the battery condition with
the Battery Status application. Generally, a battery should be
replaced when it charges to less than 80 percent of capacity.
The charging light doesnt flash
• Verify that a battery is installed in the unit.
• This may indicate that the charging process terminated. Use the
Battery Status application to determine whether a normal or
abnormal condition caused the charging process to terminate. Select

The gas gauge isnt full after charging the battery
• This may indicate that the charging process terminated prematurely.
Use the Battery Status application to determine if some condition
caused the charging process to terminate. Select Last Charge
Termination in the More Info dialog box.
