Laptop ACER E5-41 comes with no power. I checked if shorted to ground on battery terminal and charging terminal, and it was really shorted. Full shorted. I first download its schematic and analyze the circuit. I removed PQ24 and check if the board was still shorted to ground. Stiil yes. Until I realize that the charging ic OZ8691LN is shorted. I removed it. The short was gone. I replace the charging ic with a good ic, but symptoms persist. Im sure that charging ic that i put in was good, so I decided to look for another defective parts. I found out that PU5, the 3.3valw ic was heating up. When i remove it, the short was gun. Finally I replace the ic and the laptop works perfect.
