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.

Lowers the CPU processing speed first, then if necessary 
turns on the fan.
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.
