Starting again after Shut down
To start the computer up again, press the power button until the on/
off light changes to green.
If you shut down the computer by closing the display panel, you
can start it again by opening the display panel.
Using Hibernation
Hibernation mode shuts the computer down completely, but it first
saves the current mode of the computer to the hard disk. Since
Hibernation mode does not require power to maintain the saved
information, the system settings are retained indefinitely.
Restoring information from the hard disk takes longer than
restoring it from memory. When you start up again, the computer
runs a self-test, loads the operating system, and then returns to the
mode in which you left it.
Factors to consider when choosing Hibernation:
❖
While in Hibernation mode, the computer uses no battery
power
❖
Because the mode of the system is held on the hard disk, no
data is lost if the main battery discharges
❖
When starting up again, Hibernation uses less time and
battery power than does Turn Off Computer
❖
Restarting from Hibernation uses a little more time and
battery power to start up than restarting from Standby,
because information is being retrieved from the hard disk
rather than from memory
❖
When starting up again, the computer returns to the mode in
which you left it, including all open programs and files you
were using
