Operating Basics
Moving the computer
The computer is designed for rugged durability. However, a few simple
precautions taken when moving the computer will help ensure trouble-free
operation.
■ Make sure all disk activity has ended before moving the computer.
Check the HDD indicator on the computer.
■ If a CD/DVD is in the drive, remove it. Also make sure the drawer is
securely closed.
■ Turn off the power to the computer.
■ Disconnect the AC adaptor and all peripherals before moving the
computer.
■ Close the display. Do not pick up the computer by its display panel.
■ Use the carrying 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 protruded portions.
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. Use the Cooling Method item of the
Basic Setup tab in TOSHIBA Power Saver.
When the CPU temperature falls to a normal range, the fan is turned off
and the CPU operation returns to standard speed.

necessary turns on the fan.
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.
