SAFETY: When Using Your Computer
Before you open the computer cover, perform the following steps in the sequence indicated.
CAUTION:
Do not attempt to service the computer yourself, except as explained in your online Dell™
documentation or in instructions otherwise provided to you by Dell. Always follow installation and service
instructions closely.
NOTICE:
To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before
removing a component from the system board or disconnecting a device from the computer.
1
Perform an orderly computer shutdown using the operating system menu.
2
Turn off your computer and any devices connected to the computer.
3
Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot
openings at the back of the computer, 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.
4
Disconnect your computer and devices, including the monitor, from their electrical outlets. Also, disconnect any
telephone or telecommunication lines from the computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables
have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector
pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
• Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its
edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its
pins.
CAUTION:
There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with
the same or equivalent type recommended by the manufacturer. Do not dispose of the battery along with household
waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.
