Working inside your computer is safe—if you observe the
following precautions.
WARNING FOR YOUR PERSONAL SAFETY
AND PROTECTION OF YOUR EQUIPMENT
Before starting to work on your computer, per-
form the following steps in the sequence
indicated:
1. Turn off your computer and all peripherals.
2. Disconnect your computer and peripherals
from their power sources to reduce the poten-
tial for personal injury or shock. Also,
disconnect any telephone or telecommunica-
tion lines from the computer.
3. If you are disconnecting a peripheral from the
computer or are removing a component from
the system board, wait 5 seconds after turning
off the computer before disconnecting the
peripheral or removing the component to
avoid possible damage to the system board.
4. Touch an unpainted metal surface on the
computer chassis, such as the power supply,
before touching anything inside your computer.
While you work, periodically touch an unpainted
metal surface on the computer chassis to dissipate
any static electricity that might harm internal
components.
In addition, Dell recommends that you review the safety
