Computer Use

Route the power cable and all cables away from where people might walk or •
trip over them. Do not allow anything to rest on the power cable.
Do not spill anything on or into your computer. •
To avoid electrical shock, always disconnect all power, modem and any other •
cables from the wall outlets before handling the computer.

Electrostatic Discharge (ESD) Warning

Electrostatic Discharge (ESD) can cause damage to internal system components
if precautions are not taken. ESD is caused by static electricity and the damage
caused is usually permanent.
Computer technicians wear a special wrist-strap that grounds them to the
computer’s case to prevent ESD damage. You can reduce the chances of ESD
damage by doing the following:
Turn o your computer’s power and wait several minutes before starting to •
work.
Ground yourself by touching the case of the computer. •
Touch only those items which must be replaced. •
Avoid walking around while replacing items inside the case, especially if you •
are on a carpet or during low temperature and low humidity.
If you have to remove peripheral cards for any reason, place them on the •
portion of the computer’s case that was removed. Do not touch the edge
connectors at the bottom of the card that connect to the system board.
