    Asus X540UBR laptop does not turn on.

    I checked my laptop that was turned off according to the instructions of friends according to the following link: https://www.badcaps.net/forum/showth...08#post1120908 and finally checked all the paths connected to the 3.3V voltage line I tried to find a short circuit, I even removed the three ceramic capacitors connected to this line and the ground, and unfortunately the last remaining part is the two pins 81 and 587 of the Intel 8130 u CPU chip, whose resistance to ground is about 70 ohms. Unfortunately, the CPU chip is probably burned out?

      As I told you, according to this link:
      https://www.badcaps.net/forum/showth...08#post1120908
      I have already given complete information.
      Anyway, it is the full model of the Asus X540UBR rev 2.0A motherboard, and this is the board view map:
      https://www.badcaps.net/forum/attach...4&d=1648484139
      there is no problem in terms of short circuit and water corrosion, and it is suddenly turned off in the review. It turned out that the voltage of the 5-volt path is not a problem, but in the 3-volt path, there was apparently little resistance to the ground. About 70 ohms. Do you think this Intel chip has burned to the core i3 8130 u specifications?
