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 to con-
serve battery power. This mode has the following options:
• Processing speed
• Display auto off
• HDD auto off
• System auto off
• LCD Brightness
How often and how long you use the hard disk 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

based on the current power consumption rate and remaining
battery capacity. The actual remaining operating time may

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,
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.
