Conserving power
How long a fully charged battery pack 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 hard disk, DVD-ROM or multi-
function drive, diskette drives, or other optional devices.
❖
Where you are working, since operating time decreases at
low temperatures.
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.
Power profiles
You can choose from predefined power profile or select your
own combination of power management options. To do this:
1
Open the Start menu, click Control Panel, then
Performance and Maintenance.
2
Click on the Toshiba Power Saver icon.
