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 Sleep
• 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 an Express Card, to which the battery 

supplies 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.
