You can select whether to control the CPU temperature by turning on the fan first, then if necessary, lowering the CPU speed. Or, by lowering the CPU speed first, then if necessary, turning on the fan. These functions are controlled within the Power Options. When the CPU temperature falls to a normal range, the fan is turned off and the CPU operation returns to standard speed. If the CPU temperature reaches an unacceptably high level with either setting, the system automatically shuts down to prevent damage. Data in memory will be lost. Using the Hard Disk Drive (HDD) Protection This computer has a function for reducing the risk of damage on the hard disk drive. Using an acceleration sensor built into the computer, TOSHIBA 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. The TOSHIBA HDD Protection function does not guarantee that the hard disk drive will not be damaged. When vibration is detected, a message will be displayed on the screen, and the icon in the Taskbar notification area will 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.
