How to remove a computer modem

Updated: 06/30/2020 by Computer Hope

Most internal modems are built directly onto the motherboard of your computer, making them irremovable. If you do have one of the removable variety PCI (Peripheral Component Interconnect), ISA (Industry Standard Architecture), or PCMCIA follow the steps below for removing most computer modems.

Tip

You can deactivate your integrated modem in BIOS setup, which allows the installation of a PCI modem. For more information, see: How to enter and exit the BIOS or CMOS setup.

Preparation

Before you begin, it's necessary to ensure you reduce or eliminate, the risk of electrical charge damaging any of the hardware in the computer. The best way to do this is by wearing an anti-static wrist strap. While inside the computer, make sure it is disconnected from power and that you are familiar with ESD (ElectroStatic Discharge) and its potential dangers.

Open your machine

After you have removed the power cord, you must remove the side panel from the computer case. The side panel is usually held in place by several screws, or a bracket or clamp of some kind. Remove the fasteners securing the side panel, and carefully pull it off. Once the panel is removed, the inside of the computer is visible.

The modem is usually located in the bottom of the case, on the left side (circled in red above). You may see other hardware cards there as well (e.g., video card, sound card or network card).

Removing the modem

Each of the hardware cards, including the modem, is attached to the computer case by a screw or clamp. If held in place by a screw, remove this screw for the modem card only. If held in place by a clamp, release the clamp. The image below shows a modem card held in place with a screw.

Mounting screw

With the appropriate screw removed, carefully pull the modem card out of the PCI card slot on the motherboard.

Tip

When removing hardware from a PCI slot, it is better to use two hands, so there is equal force being applied to both ends. It is also helpful to use a soft "wiggling" motion to free the card.
