Chosen Solution

I bought this Mac two years ago, so it is not covered under warranty. Few days ago, in the morning when I opened the laptop I found that it is completely dead, plugged the charger. Charger was also dead. No indicator was glowing, neither on the jack of the charger nor on the laptop. Kept for sometime to see whether there was any heating. But I found that it was not even heating. But the previous day of its death, it worked completely fine, both the charger and the laptop. As our country is in lockdown, I could not even move to the nearest service centre, as all are closed. So, is it a problem of both the I/O board and logic board? Or something simple? If the boards are gone then it will cost huge I think. And now I can not spend that much. Could anyone please help me estimating the cost of repair of the laptop? Specification of the Mac: MacBook Air, 2017. Problems in short: Laptop is completely dead.Charger is completely dead. Thanks. Images are added.

There is slight yellow coloration on the cable near the magsafe jack. I don’t know whether it is identifiable in the attached picture or not.

This was caused by using a knockoff charger so do make sure you have a REAL Apple charger not a fake. Take a picture if it looks damaged and post it here for us to see Adding images to an existing question Update (05/30/2020) At this point you’ll either need to get a replacement MagSafe charger to test your system or you will need to pop off the bottom cover so you can then test the connection using a DVM to check the voltages of the MagSafe. Depending on what you find you either have a bad MagSafe charger (they do fail over time) or your logic board has a failure of a component. Make sure you get a REAL Apple unit! There are just too many knockoffs now to trust anything at a non-Apple store or online (even if they state its OEM - which its not!)
