Monitoring battery capacity
Remaining battery power can be monitored in TOSHIBA Power Saver.
Maximizing battery operating time
A battery’s usefulness depends on how long it can supply power on a
single charge, while how long the charge lasts in a battery depends on:
■
How you configure the computer in relation to its available power saving
options. The computer provides the ability to configure various power
saving settings through the TOSHIBA Power Saver, in order to
conserve battery power. As an overview these settings cover:
■
Processor speed
■
Screen brightness
■
System cooling method
■
System Standby Mode
■
System Hibernation Mode
■
Display power off period
■
Hard disk drive power off period
■
How often and for how long you use the hard disk drive and external
disk(c) drives, for example, optical disc and floppy diskette drive.
■
How much charge the battery contained to begin with.
■
How you use optional devices, such as a PC Cards, to which the
battery supplies power.
■
Whether you enable Standby Mode, which can conserve battery power
if you are frequently turning the computer off and on.
■
Where you store your programs and data.
■
Whether you close the LCD display panel when you are not using the
keyboard - closing the display saves power.
■
The environmental temperature - operating time decreases at low
temperatures.
■
You should wait for approximately fifteen seconds after turning on the
computer before trying to monitor the remaining operating time. This is
because the computer needs this time to check the battery’s remaining
capacity and then calculate the remaining operating time, based on this
together with the current power consumption.
■
Please be aware that the actual remaining operating time may differ
slightly from the calculated time.
■
With repeated discharges and recharges, the battery’s capacity will
gradually decrease. In view of this it will be noted that an often used,
older battery will not operate for as long as a new battery even when
both are fully charged. In this instance, the 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.
