1.
Touch an unpainted metal surface on the computer chassis, such as the
power supply, before touching anything inside the computer.
2.
Turn off the computer and all peripherals.
3. If you are working inside the computer, wait until the STANDBY_LED indica-
tor on the system board is off before adding or removing components or
connecting or disconnecting cables from the system board.
4.
Disconnect the computer, peripherals, and power supplies from their elec-
trical outlets. Also disconnect any telephone or telecommunication lines
from the computer. Doing so reduces the potential for personal injury or
shock.
5. While you work, periodically touch an unpainted metal surface on the com-
puter chassis to dissipate any static electricity that might harm internal
components.
6. Never place conductive objects such as tools, metal pens, or screws on the
system board.
In addition, Dell recommends that you periodically review the safety instructions at
the front of this guide.
