A customer came in with a problem, the laptop was not charging. Otherwise, it works fine - runs from a battery without an issue. The battery is original, the customer also provided his original charger.
However, when I was diagnosing the issue, I turned the laptop off, checked the board, etc. When I put everything back together, the laptop was charging (I inserted the charger and then turned the laptop on). After unplugging the charger and plugging it back,... -
