Operating Basics

This computer has a function for reducing the risk of damage on the hard 

disk drive.
Using an acceleration sensor built into the computer, HDD Protection 

detects vibration, shocks and similar signs of movement of the computer, 

and automatically moves the hard disk drive head to a safe position to 

reduce the risk of damage that could be caused by head-to-disk contact.

When vibration is detected, the following message is displayed, and the 

icon in the notification area of the taskbar is changed to the protection 

state. This message is displayed until the OK button is pressed or 30 

seconds pass. When vibration subsides, the icon returns to the normal 

state.
