The resistance of the next 13 pins to the ground is analyzed, and it is found that the short circuit to the ground is 0. Remove the capacitor PC7026 and measure it, and it is found to be a short circuit. Find a 10 Ω resistor and capacitor from the material plate, and measure the resistance of this pin to ground to return to normal.

Acer A315-55G notebook without CPU power supply maintenance: plug in the adapter, power on, repair the CPU power supply before starting up, measure the ground resistance of the next 13 pins, and find that the short circuit to ground is 0 Find a 10-ohm resistor and capacitor from the material plate and change it to measure the resistance of this foot to the ground and return to normal Plug in the adapter again and power it up All power supplies have been connected normally, and the screen lights up successfully.
