Moving the computer

While the computer is designed for rugged durability 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.

■If a CD, DVD or BD is in the drive, remove it and make sure that the disc tray is securely closed.

■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 the 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 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. 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. These functions are controlled within the Power Options.

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 to prevent damage. Data in memory will be lost.
