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■Cooling method■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 and external disk(c) drives, for example, optical disc and floppy diskette drive.

■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.
