Electrical Safety
CAUTION:
Electrical current from power, telephone, and communication cables can be
hazardous. To avoid any shock hazard, disconnect all power cords and cables as
described in the following information.
Attention:
The presence of 5 V standby power might result in damage to your
hardware unless you disconnect the power cord from the electrical outlet before
opening the computer.
For your safety, always do the following before removing the cover:
1. Shut down all programs as described in your operating-system documentation.
2. Turn off the computer and any attached devices, such as printers, monitors, and
external drives.
Note:
Personal computer users in the United Kingdom who have a modem or
fax machine attached to their computer must disconnect the telephone
line from the computer before unplugging any power cords (also known
as power cables). When the computer is reassembled, users must
reconnect the telephone line after plugging in the power cords.
3. Unplug all power cords from electrical outlets.
4. Disconnect all communication cables from external receptacles.
5. Disconnect all cables and power cords from the back of the computer.
Note:
Do not reconnect any cables or power cords until you reassemble the
computer and put the cover back on.
CAUTION:
Never remove the cover on the power supply. If you have a problem with the
power supply, have your computer serviced.
