❖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.
What to do when the battery runs low
When the battery runs low you can:
❖Plug the computer into an external power source and
recharge the battery.
❖Put the computer in Hibernate mode and replace the
battery with a charged spare.
❖Save your work and turn off the computer.
If you do not manage to do any of these things before the
battery completely runs out of power, the computer
automatically enters Hibernate mode and turns itself off.
Hibernate mode keeps track of where you were so, when you
turn on the power again, you can continue where you left off.
The computer stores the information on what you were doing
until the battery runs out of power. If you have Hibernate
mode enabled (the default), the computer copies the details of
your open programs and files to the hard disk before shutting
down.
