Each alarm can be set to alert you when a specified percentage of remaining battery power has been reached. You can set how the warning occurs: sound an alarm, display a message, both, or none. You can also set the computer to enter Standby mode or Hibernation mode or to completely power down when the alarm goes off. To change the default alarm settings: 1 Click Start, Control Panel, Performance and Maintenance, and then Toshiba Power Saver. 2 Click the Setup Action tab. 3 Configure the Alarm settings to suit your needs. Conserving battery 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.
