Genuine Dell DC power jack for Latitude 6420

This is a genuine Dell replacement Direct Current input jack with cable for the Dell Latitude 6420 laptop. It is designed specifically for models equipped with discrete Nvidia graphics. The part number is J90M8. It restores the charging connection when the original jack is damaged or worn.

Discrete-graphics-only fit with integrated cable

The jack assembly includes the cable for direct connection to the motherboard. Compatibility is limited to Latitude 6420 systems with discrete Nvidia graphics and will not fit units with integrated Intel graphics. Buyers must verify the part number J90M8 against their existing hardware before ordering to ensure correct fitment.

Replaces a failed or loose charging port

This component replaces a faulty DC power jack that prevents the laptop from charging or holding a secure connection. The jump is worth it when the original port is physically damaged, intermittent, or no longer accepts the adapter plug. It is not for buyers who need a complete power adapter or a jack for integrated-graphics models.
