Standby
Standby reduces power to system components that are not in use.
When standby is initiated, your work is saved in random access
memory (RAM), the screen is cleared, and the power/standby
lights blink. Saving your work before initiating standby is not
usually necessary but is a recommended precaution. When you
resume from standby, your work is returned instantly to the
screen.
By default, the system initiates standby after 10 minutes of
notebook inactivity when the notebook is running on battery
power and after 20 minutes of inactivity when the notebook is
running on external power. For information about changing these
settings, refer to the “Using Power Schemes” section later in this
chapter.
