5.1.1 Managing Your Notebook's Power
See Battery for more information on getting the best
performance from battery packs.
Use your notebook connected to an electrical outlet as often
as possible, as battery life expectancy is affected by the
number of times it is charged.
When leaving your notebook unattended for long periods, place it
in standby or hibernate mode. You can exit either power
management mode by pressing the power button.
