Conjunto de placa base para — placa base de repuesto Dell (MPN: Motherboard assembly for)

This replacement motherboard assembly for Dell systems is a direct-fit mainboard intended to restore or upgrade compatible Dell laptops or desktop units that use the same motherboard design. The unit includes the main printed circuit board with integrated connectors and sockets required for processor, memory, storage and common peripheral interfaces. It provides the core platform for system repair or refurbishment where the original motherboard is faulty or damaged.

Advantages

The board is supplied as a complete assembly, reducing the need to source multiple parts when performing a motherboard swap. As a manufacturer-compatible replacement it preserves original connector layouts and mounting points, which simplifies installation and maintains compatibility with existing chassis, cooling solutions, and cable harnesses. Using a replacement mainboard can restore full system functionality and support original hardware configurations for CPU, RAM and onboard ports.

Suitable for

• Repairing Dell laptops or desktops with the same motherboard design
• System refurbishment and component-level servicing
• Replacing a faulty or damaged mainboard to recover data or restore operation

Key specifications

• Main printed circuit board with integrated CPU socket and chipset components
• Memory module slots compatible with the original system’s RAM type
• Onboard storage interfaces for HDD/SSD connections
• Standard peripheral connectors and internal headers for audio, USB and network
• Mounting points and connector layout matching the original Dell chassis design

How to use

Before installation, verify model compatibility by matching the replacement motherboard to the target system’s original motherboard part number and physical layout. Power down the system, disconnect power and remove the battery if applicable. Disassemble the unit following the manufacturer’s service manual to access the existing mainboard, taking anti-static precautions. Transfer required components such as CPU, heatsink, memory modules, and storage devices if they are not integrated, then position and secure the replacement mainboard in the chassis. Reconnect all cables and peripheral connectors, reassemble the system, and perform a post-installation power-on and functional check to confirm correct operation.

Recommendations

Handle the motherboard on an anti-static surface and use an ESD wrist strap when available. Use torque-appropriate screws for mounting and ensure thermal interface material is correctly applied between CPU and heatsink. If uncertain about disassembly or firmware compatibility, consult a qualified technician or the official Dell service documentation to avoid damage and ensure BIOS/firmware settings match the hardware configuration.
