Operating Basics
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.
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.
