Introduction
If the processor's temperature reaches an unacceptably high level with 
either setting, the computer will automatically shut down to prevent any 
damage - in this instance any unsaved data in memory will be lost.
TOSHIBA HDD 
Protection
This feature uses the acceleration sensor built in 
the computer to detect vibration and shocks, and 
automatically moves the hard disk drive’s 
read/write head to a safe position in order 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 TOSHIBA HDD Protection function does not guarantee that the hard 
disk drive will not be damaged.
Hibernation Mode This feature lets you turn off the power to the 
computer without exiting from your software. The 
contents of main memory are automatically 
saved to the hard disk drive 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 more details.
Sleep Mode If you have to interrupt your work, you can use 
this feature to allow you to turn off power to the 
computer without exiting from your software. Data 
is maintained in the computer's main memory so 
that when you next turn on the power, you can 
continue working right where you left off.
