User's Manual
This feature lets you turn off the power to the
computer without exiting from your software. The
contents of main memory are automatically
saved to the internal storage drive so that when
you next turn on the power again, you can
continue working right where you left off. You
must enable the Hibernation Mode before using
this feature. Refer to the
Mode section for more details.
Mode depending on the external devices
connected to the USB ports.
For example, if a mouse or USB keyboard is
connected to a USB port, clicking the mouse
button or pressing the keyboard will wakeup the
computer.
To protect against overheating, the processor is
*1
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.
