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: [url]https://www.badcaps.net/forum/showthread.php?p=1120908#post1120908[/url] 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?I checked my laptop that was -

Sudden shutdown of the Asus K543 laptop
hello.
I have an Asus K543 laptop that did not turn on without any special problems after the last operation. The motherboard was checked for short circuit and tin dead. There was no particular problem. Mainboard model X540UBR ver 2.0 All accessories including hard drive DVD burner and ... It is disconnected from the board, but the IC shown in the picture (probably the battery charger IC) gets very hot as soon as the charging adapter is connected, and since it may damage the rest of the circuit, I could not get much voltage. I did not find this model of mainboard, friends, please help.... -
