Monitoring battery capacity
Remaining battery power can be monitored in Power Saver.
Wait at least 16 seconds after the computer has completed startup
before trying to monitor the remaining operating time. The computer
needs this time to check the battery’s remaining capacity and to calculate
the remaining operating time, based on the current power consumption
rate and remaining battery capacity. The actual remaining operating time
may differ slightly from the calculated time.
With repeated discharges and recharges, the battery’s 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.
Maximising 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
batterypower saving options. The computer provides a battery save
mode to conserve 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 supplies power.
■ Enabling Resume 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.
