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 Power Save Mode window in TOSHIBA Power Saver.
Maximum Turn on the fan first, then if necessary, lower the CPU
Performance processing speed.
Performance Use a combination of the fan and lowering the CPU
processing speed.
Battery optimized Lower the CPU processing speed first, then if necessary
turn on the fan.
When the CPU temperature falls to a normal range, the fan is turned off and the CPU
operation returns to standard speed.
NOTE: If the CPU temperature reaches an unacceptably high level with
either setting, the system automatically shuts down to prevent damage.
