2. Turn off your computer.
3. If the computer is connected to a docking device (docked), undock it.
4. Disconnect all network cables from the computer (if available).
CAUTION:
If your computer has an RJ45 port, disconnect the network cable by first unplugging the cable from your
computer.
5. Disconnect your computer and all attached devices from their electrical outlets.
6. Open the display.
7. Press and hold the power button for a few seconds to ground the system board.
CAUTION:
To guard against electrical shock, unplug your computer from the electrical outlet before performing Step
# 8.
CAUTION:
To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically
touching an unpainted metal surface at the same time as touching a connector on the back of the computer.
8. Remove any installed ExpressCards or Smart Cards from their slots.
Safety Precautions
Follow the safety precautions described in the following sections when you perform an installation or a disassembly/reassembly procedure:
•
Turn off the system and all attached peripherals.
•
Disconnect the system and all attached peripherals from AC power, and then remove the battery.
•
Disconnect all network cables, telephone or telecommunications lines from the system.
•
Use a wrist grounding strap and mat when working inside any computer system to avoid electrostatic discharge (ESD) damage.
•
After removing a system component, carefully place the removed component on an anti-static mat.
•
Wear shoes with non-conductive rubber soles to help reduce the risk of being shocked or seriously injured in an electrical accident.
Standby Power
Dell products with standby power must be completely unplugged before the case is opened. Systems that incorporate standby power are
essentially powered while turned off. The internal power enables the system to be remotely turned on (wake on LAN), suspended into a
sleep mode, and have other advanced power management features.
After you unplug a system and before you remove components, wait approximately 30 to 45 seconds to allow the charge to drain from
the circuits.
Bonding
Bonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done through the use of a
Field Service ESD kit. When connecting a bonding wire, always ensure that it is connected to bare metal and never to a painted or non-
metal surface. The wrist strap should be secure and in full contact with your skin, and be sure to always remove all jewelry such as
watches, bracelets, or rings prior to bonding yourself and the equipment.
