Changing power modes
You can use the following power modes to lengthen the life of your notebook’s
battery:
■ Standby - while your notebook is in Standby, 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. For more information
on using Hibernate mode, see “Activating and using Hibernate mode” on
page 133.
Using power saving modes
Always save your work before using Standby mode. In Standby 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.
When in Hibernate mode, your computer saves all memory information to the
hard drive, then turns the power completely off.
