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 internal storage drive, optical disc drive, 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 Sleep or Hibernation, which saves power when you turn off the computer and turn it back on again

❖Use the Windows® power-saving option plans
