Changing power modes
You can use the following power modes to lengthen the life of your notebook’s
battery:
■ Standby - while your notebook is on standby, it switches to a low power
state where devices, such as the LCD screen 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 the notebook, it reads the memory
information from the hard drive and opens the programs and documents
that were open when you activated Hibernate. For more information on
using Hibernate mode, see “Using Hibernate mode” on page 103.
Using Standby mode
Always save your work before using Standby mode. When in Standby, your
computer reduces or turns off the power to most devices except memory.
However, the information in the 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.
