What is wrong with my mac and what can i do?

OK, so my cousin was in my house and I was using my Mac book pro. As my Mac was charging she also connected her phone charger which I think was not even an official apple charger for Iphone 5s and after that something popped up on my screen and with out giving me a chance to read it, the whole computer shut down. I then checked my the charger and it was green and flashing yellow at the same time. I called the apple store and they told me to do shift control and power button and then turn it on and it didn't work. So I think 2 days past and I plug the charger again and try to turn it on and the light doesn't even show up on the charger and in the side where the green light show when you press the button to check the batter doesn't turn on.

So I just want to know what's wrong with my computer and how much do you think is gonna cost for me to fix it?

It's possible your cousin's device caused a short in your Mac, and damaged it, I suppose.

I would not get anywhere near that charger again, just in case.

I would try to go to a tech support place where you can get a chance to try a known good power unit for your MacBook Pro to see if that fixes it.

  • What's wrong with my apps and how can I fix them? I tried to connect my iPhone to my Wi-Fi router but I don't have the router set up correctly and the Wi-Fi just showed up but didn't do anything. When I turned the Wi-Fi off, I went back to my home screen and several of my apps looked like this. How do I fix them?
  • What is wrong with this iphone? And can it be fixed, and if so.how? Ugh, i'm having trouble? My cuz came to me recently with an iphone whose os seems to be erased, i don't know, i'm just saying, anyhow, when the device is turned on, a blank black screen appears, with what seems to be the apple logo on it, however it does nothing else, so. Can anyone tell me what when wrong?

I'm not really much on computers, so that is why I'm looking for something cheap, but still can have internet and play DVDs, and also if it can run videos as well.
