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
