Cabo de entrada DC Dell 7DM5H para portáteis Latitude, cabo de conector de fonte de alimentação OEM

DC input cable Dell 7DM5H for Latitude laptops is an OEM replacement power jack lead manufactured to restore the DC connection between an external AC adapter and compatible Dell Latitude notebook charging ports. Designed to replace damaged, frayed, or non-functioning DC leads, this cable reinstates power delivery and charging capability so laptops can operate normally during everyday use, repair procedures or refurbishment projects.

Advantages

This OEM power jack lead provides a direct and reliable electrical connection tailored to Dell Latitude laptops, preserving original fit and contact alignment. The cable is built for consistent conductivity and mechanical stability at the connector interface, reducing intermittent charging faults and ensuring steady power transfer. As a replacement part, it helps avoid more invasive repairs to the laptop chassis or motherboard by addressing a common point of failure.

Suitable for

• Replacing a worn, broken, or intermittent DC input cable on compatible Dell Latitude notebooks
• Repair shops performing motherboard or charging-system diagnostics
• Refurbishment projects where original-spec power connections are required
• Home users restoring charging capability after connector damage

Key specifications

• Function: DC power input cable for laptop charging
• Compatibility: Designed for Dell Latitude series laptops that use the matching connector and pinout
• Connector type: OEM-designed barrel/plug and board-side mating connector (model-specific)
• Construction: Insulated power conductors with molded connector housing for strain relief
• Purpose: Establishes DC continuity between external AC adapter and internal power circuitry

How to use

Power down the laptop and disconnect the external adapter and any peripherals before starting. Access the internal DC jack area according to the laptop service manual or repair guide—this may require removing the bottom cover and any brackets that secure the jack lead. Carefully unplug the existing cable from the motherboard connector and remove any adhesive or mounting hardware. Fit the replacement DC input cable into the same routing channel and secure it with original fasteners or clips. Reconnect the connector to the motherboard, reassemble the laptop, then connect the AC adapter to verify charging and power delivery.

Recommendations

Use only the matching cable designed for your specific Dell Latitude model to ensure proper connector fit and pin alignment. Avoid forcing the connector when seating it on the motherboard and route the cable to prevent pinching or sharp bends. If unsure about disassembly or connector compatibility, consult a qualified technician or the official service documentation.
