Monitoring battery capacity
Remaining battery power can be monitored by the TOSHIBA Power
Management Utility . Refer to Utilities in Chapter 1, Introduction .
Wait for a moment after turning on the computer before trying to monitor
the remaining operating time. The computer needs this time to check the
battery’s remaining capacity.
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.
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
battery-power 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, CD-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 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.
