Power
Repeat these steps two or three times until the battery recovers normal 
capacity.
Monitoring battery capacity
Remaining battery power can be monitored using the following methods.
Clicking the battery icon on the task bar
Via the Battery Status in the Windows Mobility Center window
Maximizing battery operating time
A battery's usefulness depends on how long it can supply power on a 
single charge, while how long the charge lasts in a battery depends on:
Processor speed
Screen brightness
System Sleep Mode
System Hibernation Mode
Display power off period
Hard disk drive power off period
How often and for how long you use the hard disk drive, optical disc and 
floppy diskette drives.
How much charge the battery contained to begin with.
How you use optional devices, such as a PC Cards, to which the 
battery supplies power.
Whether you enable Sleep Mode, which can conserve battery power if 
you are frequently turning the computer off and on.
Where you store your programs and data.
Whether you close the display panel when you are not using the 
keyboard - closing the display saves power.
The environmental temperature - operating time decreases at low 
temperatures.
The condition of the battery terminals - you should always ensure the 
terminals stay clean by wiping them with a clean dry cloth before 
installing the battery pack.
You should wait at least 16 seconds after turning on the computer 
before trying to monitor the remaining operating time. This is because 
the computer needs this time to check the battery's remaining capacity 
and then calculate the remaining operating time, based on this together 
with the current power consumption.
Please be aware that the actual remaining operating time may differ 
slightly from the calculated time.
With repeated discharges and recharges, the battery's capacity will 
gradually decrease. In view of this it will be noted that an often used, 
older battery will not operate for as long as a new battery even when 
both are fully charged.
