Changing power modes
You can use the following power modes to lengthen the life of
your notebook’s battery:
•
Sleep - while your notebook is in Sleep mode, it switches
to a low power state where devices, such as the display
and drives, turn off.
•
Hibernate - (also called save to disk) writes all current
memory (RAM) information to the hard drive, then turns
your notebook completely off. The next time you turn on
your notebook, it reads the memory information from
the hard drive and opens the programs and documents
that were open when you activated Hibernate mode.
•
Hybrid Sleep - while your notebook is in Hybrid Sleep
mode, it switches to a low power state where devices,
such as the display and drives, turn off similar to Sleep
mode. The notebook also writes all current memory
(RAM) information to the hard drive similar to Hibernate
mode. If your notebook experiences a power outage
while in Hybrid Sleep mode, the notebook reads the
memory information from the hard drive and opens the
programs and documents that were open when you
activated Hybrid Sleep mode. If the notebook does not
experience a power outage while in Hybrid Sleep mode,
it restarts using the information in current memory, thus
reducing startup time. You must turn on Hybrid Sleep
mode to use it. For more information, see
“Changing
advanced settings” on page 74 .
Using power saving modes
Always save your work before using Sleep mode. In Sleep
mode, your notebook reduces or turns off the power to most
devices except memory. However, the information in memory
is not saved to the hard drive. If power is interrupted, the
information is lost.
