Introduction
Optical Drive Power Clicking on the Optical Drive Power icon in the
taskbar will turn the power to the optical media
drive on or off. If the Optical Drive Power is set to
off, the disc tray will not open even if the eject
button is pushed - in this instance the power to
the drive can be turned on by again clicking the
Optical Drive Power icon.
HDD Protection Using the acceleration sensor built in the
computer, the HDD Protection function detects
vibrations and shocks, and automatically moves
the hard disk drive's read/write head to a safe
position to reduce the risk of damage that could
be caused by head-to-disk contact. Refer to the
Using the Hard Disk Drive (HDD) Protection
section in Chapter 4, Operating Basics, for
details.
The HDD Protection function does not guarantee that the hard disk drive
will not be damaged.
Hibernation This feature lets you turn off the power without
exiting from your software. The contents of main
memory are saved to the hard disk so that when
you next turn the power on again, you can
continue working right where you left off. Refer to
the Turning off the power section in Chapter 3,
Getting Started, for details.
Standby If you have to interrupt your work, you can turn off
the power without exiting from your software.
Data is maintained in the computer’s main
memory. When you turn on the power again, you
can continue working right where you left off.
