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:
• Processor speed
• Monitor brightness
• System standby
• System hibernate
• Turn off monitor
• Turn off hard disks
How often and how long you use the hard disk, CD/DVD-ROM 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
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

capacity will gradually decrease. Therefore, an often
used, older battery will not operate for as long as a new
battery even when both are fully charged. In this case,
Power Save Modes window in TOSHIBA Power Saver
will indicate a 100% charge for both the old and new
battery, but the displayed estimated time remaining will
be shorter for the older battery.
