To protect against overheating, the processor has 
an internal temperature sensor so that, if the 
computer’s internal temperature rises to a certain 
level, the cooling fan is turned on or the 
processing speed is lowered. This can be 
specified in the Power Options.

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 

 section in Chapter 4, 

, for more details.

For information on using this feature, please refer

working right where you left off. Refer to the 

 section in Chapter 1, 

, for more details.

memory so that when you next turn on the power, 
you can continue working right where you left off.
