My Macbook Pro 2018 is dead

[salahy]

Hi, this is my first post
So yesterday as always I slept while my macbook pro doing some data upload, anyway while I was sleeping I heard very loud noise from the laptop but I didn’t pay and attention, in the morning I woke up and I opened my laptop, it was updating to the latest version 10.15.4, it finishes and everything went fine, but I noticed the laptop isn’t charging even it was connected to the charger.

so what I did is:
I replaced the charger (I have 2)
I changed the usbc cable
I did SMC
I restarted the laptop
I did diagnose for the hardware

nothing happened
Then I connected my iPhone charger to the laptop, left side was dead and one of the ports worked the other gave me message there isn’t enough power.
I kept doing SMC and all keys combinations on the internet but still it wont charge.
Now its not working at all no sound no caps led no clickable touchpad nothing.

I am out of warranty, I saw some people had issue with the latest version.

also I should mention I had weird battery issues like draining fast some usbc ports problem but fixed by smc.
I did for 3 months charge my laptop with a 3rd party usbc cable but always I use the original charger.
What could be the problem? Is it hardware is it software what I should do ?

Sorry for the long post.

What did the loud noise sound like? A pop?

What 3rd-party cable were you using for charging?

Did your battery run down to 0, or did it still report some charge last you saw?

While you were running tests and so on, did it run OK from the adapter without draining the battery?

currently its 0 it was working normally but the ports are dead

While you were running tests and so on, did it run OK from the adapter without draining the battery?

One of the ports worked fine for the iphone and mouse but it wont charge the laptop

It could be a "failed upgrade" due to a failure of the t2 chip to update properly.
This can result in a "bricked" computer that won't start or "do anything".

Fixing a t2 failure requires either a trip to an Apple Store (or send it in to them).
It can be "done yourself" but I believe it requires ANOTHER Mac to do this (connected via USBc), and you need something called "Apple Configurator II" (free from the App Store)...

So you have a 13", right? That's a cheap 60W cable that may not even deliver 60W, and may have other issues. It's possible your battery has been stressed or damaged, which can cause all sorts of strange misbehavior. You said you ran the hardware diagnosis, but everything was normal?

Apple will do free diagnosis even if you have no warranty, but since stores are closed most places, you'd have to see if they can do it by phone.

Actually its 15”
Could the cable destroy the motherboard or the battery ?

Looks like your next stop is either going to be an Apple Store or a 3rd-party service provider...

I don't know, but that's the wrong cable for a 15", not designed to deliver the proper amount of power, so at the least your machine may have been drawing on the battery more than usual, and potentially there could be other problems from cheap cables that don't fully meet USB-C standards, which judging from tests by Benson Leung might be most of them.

If you ran the diagnostics and no trouble was detected, that would suggest the battery was still in good health, though.

If there's no Apple Store open near you, you might as well call Apple to see if they can help. They might offer free diagnosis if you'll send it to them. Or you could try a reliable third-party shop as Fishrrman suggests if you know of one.
