CHAPTER5: Managing Power
70
Changing power modes
You can use the following power modes to lengthen the life of
your convertible notebook’s batteries:
• Sleep - while your convertible 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 convertible notebook completely off. The next time
you turn on your convertible 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 convertible 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 convertible notebook also
writes all current memory (RAM) information to the hard
drive similar to Hibernate mode. If your convertible
notebook experiences a power outage while in Hybrid
Sleep mode, the convertible 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 convertible 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 73.
Using power saving modes
Always save your work before using Sleep mode. In Sleep
mode, your convertible 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.
When in Hibernate mode, your convertible notebook saves all
memory information to the hard drive, then turns the power
completely off.
