or any components.
• Don’t rock card from side to side; instead, lift card straight up from connector to remove it,
and press card straight into slot to install it.
• Don’t force card. If you meet a lot of resistance, pull card out. Check connector and slot for
damage or obstructions, then try inserting card again.
• Pull card gently to see if it is properly connected. If it resists and stays in place and its gold
connectors are barely visible, card is connected.
