Thissectionprovidesproceduresforremovingandreplacingthecomponents,assemblies,andsubassembliesintheDell™Dimension™4600Ccomputer.
Unless otherwise noted, each procedure assumes that the following conditions exist:
lYou have performed the steps in "Precautionary Measures."
lYou have read the safety information in your Product Information Guide.
lYou have opened the computer cover.
Recommended Tools
Your computer is primarily a tool-less one, but certain procedures (such as removing the heat-sink blower or the control panel) require the use of one or more
of the following tools:
lSmall flat-blade screwdriver
l#1 and #2 Phillips-head screwdrivers
lAn 8-inch, #2 Phillips-head screwdriver
Precautionary Measures
Use the following safety guidelines to help protect your computer from potential damage and to ensure your own personal safety.
Before you start to work on the computer, perform the following steps in the sequence listed:
1. Shut down the computer through the Start menu.
2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your computer, turn them off now.
3. Disconnect any telephone or telecommunication lines from the computer.
4. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.
In addition, take note of these safety guidelines when appropriate:
lWhen 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.
lHandle 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: Before you begin any of the procedures in this section, follow the safety instructions in the Owner's Manual or Product Information
Guide.
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 (or wait until the standby light is extinguished) after turning off the
computer and unplugging the power cable before removing a component from the system board or disconnecting a device from the computer.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
