Operating Basics
HDD Protection Message
Specify whether to display a message when HDD Protection is active.
Heat dispersal
To protect from overheating, the CPU has an internal temperature sensor. If
the computer’s internal temperature rises to a certain level, the cooling fan
is turned on or the processing speed is lowered. 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. Use the Cooling Method item of the Basic
Setup tab in TOSHIBA Power Saver.
When the CPU temperature falls to a normal range, the fan is turned off
and the CPU operation returns to standard speed.
This function does not work when the computer is starting, in standby, in
hibernation, in transition to hibernation, recovering from hibernation, or
powered off. Be sure not to subject the computer to vibration or impact
while the function is disabled.
