117 Mobile Computing Conserving power Disposing of used batteries You can recharge a main battery many times, so it should last for years. When the useful life of the battery expires or if the battery becomes damaged, you must discard it responsibly. The documentation that came with your computer may include an insert regarding the disposal of batteries. If not, check with your local government for information on where to recycle or dispose of old batteries. Only use replacement batteries recommended by Toshiba. CAUTION: The computer uses a lithium ion battery, which can explode if not handled or disposed of properly. 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/CD-ROM, 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.
