dynabook PORTEGE X40-J Series User Manual

Heat dispersal
*1
To protect against overheating, the processor is
equipped with an internal temperature sensor
which activates a cooling fan or lowers the
processing speed if the computer's internal
temperature rises to a certain level. You are able
to select whether to control this temperature by
either turning on the fan first, then if necessary
lowering the processor speed, or by lowering the
processor speed first, then if necessary turning
on the fan. Both of these functions are controlled
through the Power Options.
When the processor's temperature falls within
normal range, the fan and the processor
operation returns to its standard speed.
If the processor's temperature reaches an
unacceptably high level with either setting, the
computer automatically shuts down to prevent
any damage. In this instance, all unsaved data in
memory will be lost.
