Warning: When removing or installing a card, handle it only by the edges. Do not touch
its connectors or any of the components on the card. Lift the card straight out from the
connector to remove it, and insert it straight into the connector to install it. Do not rock
the card from side to side and don’t force the card into the slot. Once the replacement
card is installed, pull on it gently to check that it is properly connected.
Disconnect the booster cable from the logic board.
4.
Release the small locking clip at the front of the card’s logic board connector by pushing the
5.
clip up toward the media shelf.
Holding the card by the top corners, gently pull up the card and remove it from its

Installing the Replacement Graphics Card
Align the card’s connector with the expansion slot and press the card straight down until its
1.
connector is inserted all the way into the slot.
• Don’t rock the card from side to side; instead, press the card straight into the slot.
• Don’t force the card. If you meet a lot of resistance, pull the card out. Check the connector
and the slot for damage or obstructions, then try inserting the card again.
• Pull the card gently to see if it is properly connected. If it resists and stays in place and its
gold connectors are barely visible, the card is connected.
Connect the booster cable to the logic board.
2.
Note: There are two logic board connectors for booster cables. Connect the booster cable for
a card in PCI slot 1 to the lower connector; connect the booster cable for a card in PCI slot 2
to the upper connector (the connector closer to the optical drive).
Replace the PCI bracket and tighten its two mounting screws.
3.
Closing the Computer
Replace the access panel.

Note: Make sure the latch is in the up position before replacing the access panel. If the latch
is down, the access panel will not seat correctly in the enclosure.
Push the latch down to close and secure the access panel.
2.
Warning: Never turn on the computer unless all of its internal and external parts are
in place and it is closed. Operating the computer when it is open or missing parts can
damage it or cause injury.
