4.1 General
CAUTION:
1.
Before replacing a component, make sure that the replacement component meets the
required specifications. To avoid computer failures, never use components that do not
meet the specifications.
2.
To avoid internal damage such as short circuits and fire, never drop metal objects such as
screws, pins, paper clips, etc. into the components. When a screw is removed, be sure to
replace a screw that is the same size as the original screw. Make sure that all the screws
are fastened securely. Loose screws can cause short circuits, overheating, smoke, or fire.
3.
Before raising an FRU or other component, make sure that all the component cables have
been disconnected to avoid the risk of electrical shock caused by accidental contact with
the energized components.
4.
For AC input, be sure to use the AC adapter and AC power cable that come with your
computer or Toshiba-recommended equivalents.
5.
To avoid the risk of electrical shock, make sure that all the replacement components meet
the specifications of the computer and that all the cables and connectors are fastened
securely.
6.
Inside the PC are components that become hot during operation (such as the CPU and
cooling module). To avoid burns, let the hot components cool down before starting
inspection or repair task.
