Maximizing the Battery-Powered Operation
Using Power-Saving Options
Note:
If you have installed an operating
system, make sure you also install
the ThinkPad Features program.
The power-saving options specified in each power mode save
battery power and make it possible to use the battery pack longer
before another recharge is needed. You should select Automatic
or Customized when you travel, because Automatic mode saves
power automatically, and you can select values that use the least
power by using Customized mode.
