4.1 General 4 Replacement Procedures
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 a 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.
