Power Management
Power-Saving States 3 - 7
3
Hibernate
Hibernate uses the least amount of power of all the power-saving states and saves
all of your information on a part of the hard disk before it turns the system off. If a
power failure occurs the system can restore your work from the hard disk; if a power
failure occurs when work is saved only to memory, then the work will be lost. Hi-
bernate will also return you to where you last left off within seconds. You should
put your mobile PC into Hibernate if you will not use the computer for a period of
time, and will not have the chance to charge the battery.
Shut down
You should Shut down the computer if you plan to install new hardware (don’t for-
get to remove the battery and follow all the safety instructions in Chapter 6), plan
to be away from the computer for several days, or you do not need it to wake up and
run a scheduled task. Returning to full operation from Shut down takes longer than
from Sleep or Hibernate.
