from abnormal conditions such as a voltage
overload from the AC adaptor. This can be
specified in the Power Options.

that computer operation cannot be continued, the
system automatically enters Hibernation Mode
and shuts itself down. This can be specified in the
Power Options.
Heat dispersal
*1
To protect against overheating, the processor has
an internal temperature sensor so that, if the
computer's internal temperature rises to a certain
level, the cooling fan is turned on or the
processing speed is lowered. This can be
specified in the Power Options.
If the processor's temperature reaches an unacceptably high level with
either setting, the computer will automatically shut down to prevent any
damage - in this instance all unsaved data in memory will be lost.

models uses the acceleration sensor built in the
