Replacing the Computer Cover
Overview
Your Dell Precision 610 system supports a variety of internal options that expand system capabilities. This chapter prepares you to
install options inside the computer. It describes how to remove and replace the computer cover and rotate the power supply away
from the system board. It also familiarizes you with the internal components you may handle if you install Dell hardware options.

Before You Begin

To make working inside your computer easier, make sure you have adequate lighting and a clean work space. If you temporarily
disconnect cables or remove expansion cards, note the position of the connectors and slots so that you can reassemble the system
correctly.
You will use the information in this section every time you install a hardware option inside your computer. Read this section
carefully, because the information is not repeated in detail elsewhere in this guide.

Safety First-For You and Your Computer

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, perform the following steps in the sequence indicated:
1. Turn off your computer and all peripherals.
2. Disconnect your computer and peripherals from their AC power sources. Also, disconnect any telephone or
telecommunication lines from the computer. Doing so reduces the potential for personal injury or shock and damage to
system components.
3. If you are disconnecting a peripheral from the computer or are removing a component from the system board, wait 10 to 20
seconds after disconnecting the computer from AC power before disconnecting the peripheral or removing the component to
avoid possible damage to the system board.
To verify that all power has been removed from the system, make sure that the standby light-emitting diode (LED) on the
system board has gone out. For the location of this LED, see Figure 9-1.
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. Also avoid touching components or contacts on a card and avoid touching pins on a chip.
In addition, Dell recommends that you periodically review the safety instructions at the front of this guide.
