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.
Maximum
Performance
Turns on the fan first, then if necessary, lowers the CPU
processing speed.
Performance Uses a combination of the fan and lowering the CPU
processing speed.
Battery
optimized
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.
