Maximizing battery operating time
A battery’s usefulness depends on how long it can supply power on a
single charge. How long the charge lasts in a battery depends on:
■ CPU processing speed (Depends on the model you purchased)
■ Screen brightness
■ Cooling method (Depends on the model you purchased)
■ System Sleep Mode
■ System Hibernation
■ Monitor power off
■ How often and how long you use the hard disk, optical disc.
■ How much charge the battery contained to begin with.
■ How you use optional devices, such as a PC Card, to which the battery
supplies power.
■ Enabling Sleep Mode conserves battery power if you are frequently
turning the computer off and on.
■ Where you store your programs and data.
■ Closing the display when you are not using the keyboard saves power.
■ Operating time decreases at low temperatures.
■ The condition of the battery terminals. Make sure the battery terminals
stay clean by wiping them with a clean dry cloth before installing the
battery pack.
