Care and use of the battery pack

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 Precessing 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, CD/DVD-ROM drive and the diskette drive.

How much charge the battery contained to begin with.

How you use optional devices, such as a PC card, to which the battery sup- plies power.

Enabling Resume mode conserves battery power if you are frequently turn- ing 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.
