Question Laptop doesn't turn on ?

[Aleh Hutnikau]

Laptop model: Acer Nitro 5 AN515

At one point the laptop turned off and does not turn on anymore. When connecting the power supply, it goes into protection mode (until you take it out of the socket and turn it on again). You can also hear a clear spark sound when connecting the power supply. The resistance on the power connector in the laptop is 500 ohms, i.e. there is no short circuit. Apparently, the short circuit occurs when voltage is applied.

By ringing the circuit, I found out that one of the diodes (it seems) has a short circuit. It is located right under the central processor. Marking: 220 13n2x.

I tried to find information about this diode on the Internet, but I did not find anything.

Could this be the cause?

Where can I find this diode or its analogue?

the color of the board seems odd. try cleaning with brush and isopropyl alcohol, then let it dry for about 3 hours. try powering on again

i think this component is not a diode but a capacitor
