Suddenly phone is dead for no reason (it has non-removable battery) We have a Micromax Q380 at home which is running Lollipop. It was working fine last night and suddenly it is not  responding this morning. Power button and it's combination with volume buttons won't work. It just looks like a dead phone. Display doesn't light up at all, even when charging. It's battery is non-removable which is the sad part of the story. What can I try before handing it over to a service store?
Battery got so drained that the display doesn't turn up even when charging it. There was no problem with the mobile at all. My bad. Now it is up and running after hours of charging. I am not deleting this silly question because somebody might face similar silly issues in the future. Ain't they? ;-)
