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 
computer. 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. 

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

Inside the PC, locate the add-in card slots on the 
motherboard. 

4

Release the latch that retains the cards by pressing 
the two tabs at the top of the add-in slots inside 
the chassis. Some PCs use a screw instead of the 
retaining latch to secure each add-in card; remove 
the screw. 

5

Holding the card at each end, carefully rock it back 
and forth until the connectors pull free from the 
socket, and then remove the card. Be sure not to 
scrape the card against the other components. 
Store the old card in the anti-static packaging that 
contained your new card. 

6

If you are not replacing the old add-in card with a 
new add-in card, close the open slot by inserting 
the metal slot cover into the opened slot. Replace 
the latch or insert the screw. 

Installing an Add-in Card 

1

Align the edge of 
the add-in card 
with the slot on the 
chassis and gently 
but firmly press the 
card straight down 
into the add-in 
card slot. The 
whole connector 
should be seated 
properly in the 
card slot. 

2

Replace the latch by pressing in on the square tabs 
on the outside of the chassis. The latch should move 
down so that it locks into position over the cards. If 
it does not latch, check that each card is completely 
seated into its card slot. 

Or 

Insert the retaining screw. 

3

Set the chassis upright. 

4

Complete the procedures to replace the side panel, 
and close the PC. See “Opening and Closing the 
PC“ on page 1. 

NOTE:

 If the new card or device isn’t working, read 

through the card manufacturer’s installation 
instructions, and recheck all connections, including 
those to the card, power supply, keyboard, and 
monitor.
