Ok. I'm starting to panic. I was transferring photos from my phone to my laptop using my phone's USB. While doing so, my laptop is also being charged with the power on. Half way through, my laptop suddenly shut down with a very faint sound. Something like electricity being turn off. I tried turning back on and it won't work. I also tried turning the main power supply on and off and on again and it still doesn't work.
Used my phone to Google and many ask to remove the battery and try turning in on with the power plug but the thing is this laptop has a built in battery.
You should contact the reseller in case the laptop has some warranty left. As far as I can tell, we are talking about some power issue that might have damaged not only the power supply or the battery. Anyways, an experienced technician should examine the laptop.
