Standby and Hibernation
Standby and hibernation are energy-saving features that conserve
power and reduce startup time. They can be initiated by you or
by the system. Refer to the “Initiating Standby, Hibernation or
Shutdown” section, later in this chapter, for details about when
to use each setting.
Standby
Ä
CAUTION: To avoid a complete battery discharge, do not leave your
notebook in standby for extended periods. Connect the notebook to an
external power source.
Standby reduces power to system components that are not in use.
When standby is initiated, your work is saved in random access
memory (RAM) and the screen is cleared. When you resume
from standby, your work returns to the screen where you left off.
Saving your work before initiating standby is not usually
necessary but is a recommended precaution.
When the notebook is in standby, the power/standby light
blinks.
