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. If you use
Windows 95, you can set the
Cooling Method
in the
System
window of
Power Mode Setup
in Power Saver. If you use Windows 98, 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
Fan
item of the
Power Save Mode
window in 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. In Windows 95, it shuts
down in Hibernation mode. In Windows 98, the mode depends on the
setting in Power Saver: Shutdown, Resume or Hibernation.
