I left my working laptop for uploading. It was connected with charger . I came after 45 minutes and found my laptop Power Off. Then I tried power on several ways. But Its not getting Power-On even the power LED is not blinking. I tried power draining by disconnecting battery and charger but nothing helping.
Two year back i had the same problem then a power IC was replaced and my laptop got working. But now I think its not motherboard problem.
