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.
