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:

■How you configure the computer (for example, whether you enable battery-power saving options). The computer provides a battery save mode, which can be set in TOSHIBA Power Saver, to conserve battery power. This mode has the following options:

■CPU Processing speed

■Screen brightness

■Cooling Method

■System standby

■System Hibernation

■Monitor Power off

■HDD Power off

■How often and how long you use the hard disk drive, optical disc drive and the floppy disk drive.

■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 Standby 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.
