Moving the computer
The computer is designed for rugged durability. However, a few simple
precautions taken when moving the computer will help ensure
troublefree operation.
■ Make sure all disk activity has ended before moving the computer.
Check the Builtin HDD indicator on the computer and the indicator
on any external disk drive.
■ If a diskette is in the external disk drive, remove it.
■ 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.
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.
Maximum
Performance
Turn on the fan first, then if necessary, lower the
CPU processing speed.
Performance Use 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.
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.
