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 Disk 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.
■ Close all port covers.
■ 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 Power
Save Mode window 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.
Never spray cleaner directly onto the computer or let liquid run into any
part of it. Never use harsh or caustic chemical products to clean the
computer.
Maximum
Performance
Turn on the fan first, then if necessary, lower the
CPU processing speed.
Performance Uses a combination of the fan and lowering the CPU
processing speed.
Battery optimised Lower the CPU processing speed first, then if
necessary turn 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.
