Operating Basics
Moving the computer
While the computer is designed for flexible day-to-day usage you should
exercise a few simple precautions when moving it in order to help ensure
trouble-free operation.
■ Make sure all disk/disc activity has ended before moving the computer -
check that the HDD and other indicators on the front of the computer
are off.
■ Turn off (shut down) the computer.
■ Disconnect the AC adaptor and all peripherals before moving the
computer.
■ Close the display panel.
■ Do not pick up the computer by its display panel.
■ Before carrying your computer, shut it down, disconnect the AC adaptor
and allow it to cool down - a failure to follow this instruction may result in
minor heat injury.
■ Be careful not to subject the computer to impact or shock - a failure to
follow this instruction could result in damage to computer, computer
failure or loss of data.
■ Never transport your computer with any cards installed - this may cause
damage to either the computer and/or the card resulting in product
failure.
■ Always use a suitable carry case when transporting the computer.
■ When carrying your computer, be sure to hold it securely so that it does
not fall or hit anything.
■ Do not carry your computer by holding any of its protruding elements.
Heat dispersal
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 will be
turned off and the processor operation returned 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.
