Putting spent batteries in the trash is not only irresponsible, it may also be illegal. Dispose of the battery as required by local ordinances or regulations. 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 Multifunction drive, and 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.
