    Re: Acer NITRO 5 AN515-54-52UH Not booting

    Can you confirm..after the solder blob was removed, what are the resistance readings for the cap near the inductor you are measuring?

    One side of the cap will be ~0 ohms since it is ground.

    What is the exact resistance of the other side of the same cap? Is it still ~2R4 ohms?

    If the reading is now high then the IC that creates the voltage rail is NOT shorted.

    Also concerned about the 3 caps that are at an angle near the solder blob.

    With care, flux and hot air with low air pressure to straighten out each of these caps. Keep the air pressure low and away from the plastic connector so it does not melt.

      The resistance is still the same. So 0.1 on the ground side of the cap and 2R4 ohms on the IC side of the cap.

      I also cleaned up the 3 caps and put them straight on the board but for the readings it made no difference.

      Should I replace the IC now and see if that fixes the problem?
