A 'Chip' near battery connector is heating up and making hissing sound, while charging. I Thought its battery so i got it replaced, but its still the same. The Chip squarish with rounded cornerd 10mm x 10mm is just near the battery connector and marked "4R7 403 W47".
Edit : Its probably an inductor.
Questa è una buona domanda?

Thankyou. Can I use the macbook for sometime, Will take some time to do the repair. 1-2 weeks maybe.
You run the risk of the inductor fully failing which could damage other parts.
I agree.. it might damage battery and/or other components on the same rail. It might burn and give sparks too. Avoid if you can.
