105 Power Management Conserving power 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, CD-ROM, and diskette drives. Whether you use any optional devices to which the battery supplies power. 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 mode, 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 usage modes. Using one of these modes 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 usage mode and discuss each power-saving option.
