DC Power Jack Failure

In most cases, 95% of the time, the internal DC Power Jack on a laptop has to be replaced. Unfortunately, the connections directly on the motherboard of the laptop are faulty. Operating a laptop with a faulty DC power connector for long periods of time while moving the power cord to the right position to work can also eventually damage the motherboard.

The center “positive” pin on this power jack (soldered directly to the motherboard) usually breaks first when a DC jack is intermittent or fails to work at all. When this happens, the DC Power Jack needs complete De-soldering and a new DC Power Jack replaced into the motherboard then tested.

An internal DC Power Jack on a laptop “unseats” from the solder joints, or the thin pin snaps away from the board causing the electric circuit to stop or become intermittent.
