I am using a Sony Vaio 15 Inch laptop "SVF15N12SN" from 2014 and it was working fine till yesterday.
Yesterday night while I was working on it, I got a huge burst sound with burning smell and smoke from the laptop. I immediately removed the plug and switched off the laptop. The battery got busted and backpanel was damaged, and the laptop is not switching ON. I believe its because of non-removable battery. The laptop is not under warranty and I am looking for a favourabe solution from Sony.
