Moto G not starting, only notification light blinks.

Hi, I have a query. My phone Moto G (1st Gen) is not starting only the white notification light blinks when pressing power button. I tried to get it repaired in a shop but he told me that there is an issue with the BCM IC (Battery Chemistry ....), he told me that he was unable to find it in the market. Can any one please suggest me where can i get this and is there anything else that can be done(Please dont suggest to buy a new phone) As this is the first phone i bought with my first salary. Please help me out with this. Thanks.
