The laptop charging cable becomes extremely warm and causes charging problems.
I have a Lenovo Thinkpad X1 Yoga Gen 1 with an i7-6600U processor. I’m experiencing charging issues where the charging indicator on the screen flips between showing and not showing charge every few seconds. The laptop isn’t actually charging, and the wire section near the ferrite beads gets excessively hot—only that part warms up, not the whole cable. This is unusual for a charger I own, which usually heats up when plugged in. Should I replace the charger or just a component?
The internal wiring appears damaged, leading to high resistance in that part of the cable, resulting in voltage drop and weak charging performance. If you're comfortable with soldering, it should take about five minutes to repair it. However, I wouldn't recommend attempting this without proper knowledge.
