My Mac Book Air was dead for over two months. I tried contacting Apple Service Center for the same and they quoted me 45K for the replacement of mother board and another 13K for the battery. I lost all hope as there is no trade-in and no buy back for something worthy.
Farman at Fam Care told me that there was a problem with power IC and he got it replaced along with the new battery for just 15.5K.
I would recommend everyone to contact him for all Apple Products and do not get Apple Care as Apple Service Center tries their best to extort money out of our misery.
Most importantly, he got it done within a day and he explains you the problem like his own. So kudos to him and his team at Fam Care.
