How to repair the charging adapter of the Microsoft Surface Pro 3/4/5/6/7

Difficulty

Moderate

Steps

Time Required

30 minutes

Introduction

Due to design choices, in the connector of the Microsoft Surface Pro (3 and later) is prone to failure. The positive and negative wires short making the adapter unusable.

Fortunately the circuit is well designed and can resist a short, so it is sufficient to remove the short to get the adapter working again. It’s an easy fix!

Tools

Step 1

Open the connector by inserting a blade in the two slots on the end.
Some glue spots are holding the outer case on the connector
Detach the glue with a blade and proceed to next step

Step 2

Slide the outer case of the connector towards the cable side to uncover the connector

Step 3

With the help of a knife or a pair of tweezers, remove the resin to uncover the wires.
Be gentle!

Step 4

Microsoft inserted this protective spacer to prevent short of the positive and negative conductors.
Unfortuately this is not sufficient in many cases. We will replace this with a bigger spacer in the next step
Remove the red spacer

Step 5

Here is the short! Some threads burned, if they are not a significant portion, this can be ignored
The two poles touched here, let's clean this area and remove any debris

perfect resolution.

i did the same and booom its working

Step 6

After clearing the connector from any wires that can touch, use a sewing needle and a cotton thread to well insulate the two wires
Use multiple turns to ensure the two poles can never touch each other again

Step 7

Test that the adapter is working again before closing the connector. The white LED should turn on when plugged in your Surface Pro

Conclusion

To reassemble your device, slide on again the protective outer casing

Nice guide for fixing the Surface Pro charger that I’ve used to fix SP6 charger that was intermittently charging at first and not charging at all later.

Was, wenn das Kabel beschädigt ist? Kann man das selbst reparieren? Danke, Oskar

I don't think so, unfortunately! You can cut some sections and resolder it to the end connector, but that is an advanced repair, and only works if the damaged end is on the connector side

I've replaced my charger 3 times, twice with cheap off-brand replacements. These instructions let me avoid a 4th! My cheap replacement charger had even less insulation than the original. Yikes!! But now it's working great again! Thanks so much! I will check this site before replacing my stuff in the future. :D

Thank you! This is the only solution that works for me! All the other official solutions posted on the Microsoft site were useless.
