To manage power manually

In addition to allowing the notebook to enter its power-saving modes automatically, you
can also put it into any of the following three modes whenever you need to.
Make a habit of saving your work before putting your notebook on standby. If
power is interrupted while the notebook is on standby, any unsaved data will be
lost.
You can also turn off the display by closing the lid.
In addition, you can configure the notebook so that closing the lid or pressing the power
button puts the notebook on standby or into hibernation, or turns it off—see "To set
power management properties" on page 49.
