Genuine Dell IO Daughter Board

This genuine Dell replacement IO circuit board provides two USB jacks and one FireWire jack for Dell Studio 1535, 1536, and 1537 laptops. It restores the original port layout when the factory board fails. The part number is F965C, also referenced as M264C. A ribbon cable is included for connection to the mainboard.

Included Ribbon Cable Simplifies Installation

The supplied ribbon cable connects the daughter board directly to the motherboard header without extra sourcing. Screws are not included, so the original fasteners must be reused. This keeps the repair focused on the port assembly itself rather than hunting for compatible cabling.

Direct Fit for Studio 15 Series Only

The board fits exclusively in Dell Studio 1535, 1536, and 1537 chassis and will not align with other Dell ranges or third-party notebooks. It handles the two USB ports and single FireWire interface native to those models. Builders needing additional ports, different interfaces, or a full motherboard replacement must look elsewhere.

Questions about this item

Will the F965C board need a new ribbon cable later?

The replacement board ships with its own ribbon cable, so no separate cable purchase is required.

What fails first when the USB ports run continuously?

The USB jack solder joints on the daughter board are the typical wear point under constant plug cycles.

Does the F965C run hot or noisy during all-day use?

The board is a passive component with no fan or active circuitry, so it produces no noise and negligible heat.
