Removing or Installing an Add-in Card
An add-in card is a circuit board, such as a PCI or an AGP card, that fits into a PC add-in
card slot. Your PC contains several add-in card slots that can be used to add components
to your PC. The PC component configurations vary by model.
A flat-head and a Phillips screwdriver are needed to remove, replace, or add an
add-in card.
Removing an Add-in Card
1 Complete the procedures to prepare the PC and to remove the side panel. See
“Opening and Closing the PC” on page 1.
2 Gently lay the PC on its side.
3 On the back of the PC, remove the screw from the bracket cover for the add-in card
slots, and then remove the bracket cover.
WARNING: Do not overload the system by installing add-in cards that draw
excessive current. The system is designed to provide two amps (average) of
+5 V
v power for each board/card in the computer. The total +5 Vv current
draw in a fully loaded system (one with all add-in card slots filled) must not
exceed the total number of slots multiplied by two amps.
NOTE: A power supply upgrade may be required for certain graphics card upgrades.
Check with the graphics card supplier for more information about power supply
requirements.
