This 7.4mm × 5.0mm female barrel female DC jack with pre-attached cable harness fits: Latitude E6420 Latitude E6430 Latitude E6440 Latitude E6520 Latitude E5440 Match the connector type on your existing charger before ordering. If your laptop charges via a 7.4mm × 5.0mm female barrel barrel, this part is the correct fit — no other variant of jack will physically mate with the OEM charger. Common DC jack failure symptoms If any of these match your laptop, the jack is the likely culprit: Charger LED is on, but laptop only charges if you wiggle the cable at a specific angle Battery indicator on screen flickers between 'charging' and 'not charging' randomly You feel the jack move when you push on the charger plug The plug feels loose; the connection isn't snug like it used to be Charging suddenly cuts out when you bump the laptop If two or more of these match, the internal jack solder pads have likely cracked from years of plug-in / plug-out stress. Replacing the harness is a permanent fix. Installation — step by step Most modern laptops use a cable-harness jack like this one (rather than a board-soldered jack), so installation is screwdriver-only: Power off laptop, remove AC and battery Unscrew bottom panel (8-12 Phillips, sometimes Torx T5) Locate old DC jack pigtail connector on motherboard Unlatch ribbon / unplug 2-pin connector Remove old jack from chassis (1-2 screws, sometimes glued — gently pry) Seat new jack into the same recess, screw down Plug new harness into motherboard connector Reassemble, test with charger before fully closing Total time: 20-30 minutes for someone comfortable with laptop teardown. We do free installation in shop if you bring the laptop to Hafeez Center. Build quality & why we sell this specific part OEM-grade plastic body with proper metal contacts for the centre-pin and outer-barrel return. The wire harness uses heavier 22 AWG copper than no-name aftermarket parts — important because a Latitude E6420 charger draws up to 4-6A and thinner copper would heat up under load. The motherboard-side connector is the correct keyed JST type, so it only fits one way and you can't reverse it.

No questions asked within the warranty window. Frequently asked questions Is the cable harness already attached? Yes. The jack ships with a 6-8cm wire pigtail pre-soldered to the jack and terminated with the small 2-pin or 4-pin motherboard connector — just plug it into the board, no soldering required for the harness side. Will the charger plug feel loose or work intermittently after I install this jack? If the new jack is seated correctly on the motherboard and the solder joints are clean, the plug should feel firm — no wobble, no flicker. A loose-feeling charger after replacement usually means a cold solder joint on one of the four mounting pads. Does this fit the Latitude E6420? Yes — this exact jack matches the OEM part number and connector size for the Latitude E6420, Latitude E6430, Latitude E6440. We've sold dozens of these to repair shops across Lahore.

Symptoms: laptop only charges if the plug is held at an angle; charging stops when you wiggle the cable; battery indicator flickers between charging and discharging on screen. If your charger LED is on but the laptop says 'plugged in, not charging' randomly, the jack is the likely culprit. N.N Laptops — Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore.
