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 window in TOSHIBA Power
Saver.

lost.
