Finding the source of a partial short circuit caused by a faulty BQ Chip. Later on we get to focus on why the Laptop is not generating the main 19v power rail.
A very good video but, I cant see exactly what you are doing coz the camera is facing somewhere else. I can on hear what you are doing than see. Can you please focus the camera on what you are doing, want to see how you test, remove the ic, and where you test.
