Monitoring the Battery Charge

Battery life is affected by factors such as the power-management settings in System Setup, the applications you use, and the brightness settings of the LCD. Under normal usage, the battery charge lasts approximately 3 hours for standard battery (undocked), 1 1/2 hours on standard battery (docked) and approximately 5 hours for the long life battery (undocked).

Battery life estimates are subject to variation. The actual life of your battery may be less than the estimates given in the manual.
