The value displays as a percentage of remaining battery
charge.
TECHNICAL NOTE: The computer drains the battery faster at low
temperatures. Check your remaining charge frequently if you are
working in temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based on
your current rate of power use and other factors such as the age of
the battery.
Conserving battery power
How long a fully charged battery lasts when you are using the
computer depends on a number of factors, such as:
❖How the computer is configured
❖How much you use the display panel instead of an
external monitor
❖How much you use the hard disk and other drives
❖Whether you use any optional devices to which the
battery supplies power, such as a PC Card
❖Where you are working—since operating time decreases
at low temperatures
Toshiba’s power-saving options greatly increase the length of
time you can use the computer before it becomes necessary to
recharge the battery.
Toshiba has combined these options into preset power usage
modes.
You may also set individual power-saving options to suit your
own needs. See “Power Management” on page215 for
details.
