Conserving power
5.375 x 8.375 ver 2.3
There are various ways in which you can conserve power and
extend the operating time of your battery:
❖ Enable Standby or Hibernation, which saves power when
you turn off the computer and turn it back on again.
❖ Use Toshiba’s power-saving options.
These power-saving options control the way in which the
computer is configured. By using them, you can greatly
increase the length of time you can use the computer before
you need to recharge the battery.
Toshiba has combined these options into preset power
profiles. Using one of these profiles lets you choose between
maximum power savings and peak system performance. You
may also set individual power-saving options to suit your own
needs.
The following sections describe how to choose a power
profile and discuss each power-saving option.
