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.
WARNING: Do not overload the system by
installing add-in cards that draw excessive
current. The system is designed to provide
2 amps (average) of +5 V power for each
board/card in the PC. The total +5 V
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 2 amps.
A Phillips screwdriver is needed to remove, replace,
or add an add-in card.
Removing an Add-in Card
1 Complete the procedures to prepare the PC and
remove the side panel. See “Opening and Closing
the PC” on page 1.
2 Gently lay the PC on its side.
3 Inside the PC, locate the add-in card slots on the
motherboard.
4 If you are replacing a card, make a note of any
external or internal cables attached to the card,
and then disconnect them.
